`associateAddress( array $args = array() )`

Executes the AssociateAddress operation.

Associates an Elastic IP address with an instance or a network interface.

An Elastic IP address is for use in either the EC2-Classic platform or in a VPC. For more information, see Elastic IP Addresses in the Amazon Elastic Compute Cloud User Guide.

[EC2-Classic, VPC in an EC2-VPC-only account] If the Elastic IP address is already associated with a different instance, it is disassociated from that instance and associated with the specified instance.

[VPC in an EC2-Classic account] If you don't specify a private IP address, the Elastic IP address is associated with the primary IP address. If the Elastic IP address is already associated with a different instance or a network interface, you get an error unless you allow reassociation.

This is an idempotent operation. If you perform the operation more than once, Amazon EC2 doesn't return an error.

#### Examples

`associateDhcpOptions( array $args = array() )`

Executes the AssociateDhcpOptions operation.

Associates a set of DHCP options (that you've previously created) with the specified VPC, or associates no DHCP options with the VPC.

After you associate the options with the VPC, any existing instances and all new instances that you launch in that VPC use the options. You don't need to restart or relaunch the instances. They automatically pick up the changes within a few hours, depending on how frequently the instance renews its DHCP lease. You can explicitly renew the lease using the operating system on the instance.

For more information, see DHCP Options Sets in the Amazon Virtual Private Cloud User Guide.

#### Examples

EC2-VPC: You can have up to 50 rules per group (covering both ingress and egress rules).

Rule changes are propagated to instances within the security group as quickly as possible. However, a small delay might occur.

[EC2-Classic] This action gives one or more CIDR IP address ranges permission to access a security group in your account, or gives one or more security groups (called the source groups) permission to access a security group for your account. A source group can be for your own AWS account, or another.

[EC2-VPC] This action gives one or more CIDR IP address ranges permission to access a security group in your VPC, or gives one or more other security groups (called the source groups) permission to access a security group for your VPC. The security groups must all be for the same VPC.

# `public `Guzzle\Service\Resource\Model``
`copySnapshot( array $args = array() )`

Executes the CopySnapshot operation.

Copies a point-in-time snapshot of an EBS volume and stores it in Amazon S3. You can copy the snapshot within the same region or from one region to another. You can use the snapshot to create EBS volumes or Amazon Machine Images (AMIs). The snapshot is copied to the regional endpoint that you send the HTTP request to.

Copies of encrypted EBS snapshots remain encrypted. Copies of unencrypted snapshots remain unencrypted, unless the Encrypted flag is specified during the snapshot copy operation. By default, encrypted snapshot copies use the default AWS Key Management Service (AWS KMS) customer master key (CMK); however, you can specify a non-default CMK with the KmsKeyId parameter.

For more information, see Copying an Amazon EBS Snapshot in the Amazon Elastic Compute Cloud User Guide.

#### Examples

- Basic formatting example

      $result = $client->copySnapshot(array(
          'DryRun' => true || false,
          // SourceRegion is required
          'SourceRegion' => 'string',
          // SourceSnapshotId is required
          'SourceSnapshotId' => 'string',
          'Description' => 'string',
          'DestinationRegion' => 'string',
          'PresignedUrl' => 'string',
          'Encrypted' => true || false,
          'KmsKeyId' => 'string',
      ));

#### Parameters

$args
  `array`
  $arg Associative array containing the following keys (required keys are bold):
  - DryRun => (bool)

    Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

  - SourceRegion => (string)

    The ID of the region that contains the snapshot to be copied.

  - SourceSnapshotId => (string)

    The ID of the EBS snapshot to copy.

  - Description => (string)

    A description for the EBS snapshot.

  - DestinationRegion => (string)

    The destination region to use in the PresignedUrl parameter of a snapshot copy operation. This parameter is only valid for specifying the destination region in a PresignedUrl parameter, where it is required.

    CopySnapshot sends the snapshot copy to the regional endpoint that you send the HTTP request to, such as ec2.us-east-1.amazonaws.com (in the AWS CLI, this is specified with the --region parameter or the default region in your AWS configuration file).

  - PresignedUrl => (string)

    The pre-signed URL that facilitates copying an encrypted snapshot. This parameter is only required when copying an encrypted snapshot with the Amazon EC2 Query API; it is available as an optional parameter in all other cases. The PresignedUrl should use the snapshot source endpoint, the CopySnapshot action, and include the SourceRegion, SourceSnapshotId, and DestinationRegion parameters. The PresignedUrl must be signed using AWS Signature Version 4. Because EBS snapshots are stored in Amazon S3, the signing algorithm for this parameter uses the same logic that is described in Authenticating Requests by Using Query Parameters (AWS Signature Version 4) in the Amazon Simple Storage Service API Reference. An invalid or improperly signed PresignedUrl will cause the copy operation to fail asynchronously, and the snapshot will move to an error state.

  - Encrypted => (bool)

    Specifies whether the destination snapshot should be encrypted. There is no way to create an unencrypted snapshot copy from an encrypted snapshot; however, you can encrypt a copy of an unencrypted snapshot with this flag. The default CMK for EBS is used unless a non-default AWS Key Management Service (AWS KMS) CMK is specified with KmsKeyId. For more information, see Amazon EBS Encryption in the Amazon Elastic Compute Cloud User Guide.

  - KmsKeyId => (string)

    The full ARN of the AWS Key Management Service (AWS KMS) CMK to use when creating the snapshot copy. This parameter is only required if you want to use a non-default CMK; if this parameter is not specified, the default CMK for EBS is used. The ARN contains the arn:aws:kms namespace, followed by the region of the CMK, the AWS account ID of the CMK owner, the key namespace, and then the CMK ID. For example, arn:aws:kms:us-east-1:012345678910:key/abcd1234-a123-456a-a12b-a123b4cd56ef. The specified CMK must exist in the region that the snapshot is being copied to. If a KmsKeyId is specified, the Encrypted flag must also be set.

#### Returns

``Guzzle\Service\Resource\Model``
Returns a response Model object

- SnapshotId => (string)

  The ID of the new snapshot.

# `public `Guzzle\Service\Resource\Model``
`createCustomerGateway( array $args = array() )`

Executes the CreateCustomerGateway operation.

Provides information to AWS about your VPN customer gateway device. The customer gateway is the appliance at your end of the VPN connection. (The device on the AWS side of the VPN connection is the virtual private gateway.) You must provide the Internet-routable IP address of the customer gateway's external interface. The IP address must be static and can't be behind a device performing network address translation (NAT).

For devices that use Border Gateway Protocol (BGP), you can also provide the device's BGP Autonomous System Number (ASN). You can use an existing ASN assigned to your network. If you don't have an ASN already, you can use a private ASN (in the 64512 - 65534 range).

Amazon EC2 supports all 2-byte ASN numbers in the range of 1 - 65534, with the exception of 7224, which is reserved in the us-east-1 region, and 9059, which is reserved in the eu-west-1 region.

For more information about VPN customer gateways, see Adding a Hardware Virtual Private Gateway to Your VPC in the Amazon Virtual Private Cloud User Guide.

You cannot create more than one customer gateway with the same VPN type, IP address, and BGP ASN parameter values. If you run an identical request more than one time, the first request creates the customer gateway, and subsequent requests return information about the existing customer gateway. The subsequent requests do not create new customer gateway resources.

#### Examples

- Basic formatting example

      $result = $client->createCustomerGateway(array(
          'DryRun' => true || false,
          // Type is required
          'Type' => 'string',
          // PublicIp is required
          'PublicIp' => 'string',
          // BgpAsn is required
          'BgpAsn' => integer,
      ));

#### Parameters

$args
  `array`
  $arg Associative array containing the following keys (required keys are bold):
  - DryRun => (bool)

    Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

  - Type => (string: ipsec.1 )

    The type of VPN connection that this customer gateway supports (ipsec.1).

  - PublicIp => (string)

    The Internet-routable IP address for the customer gateway's outside interface. The address must be static.

  - BgpAsn => (int)

    For devices that support BGP, the customer gateway's BGP ASN.

    Default: 65000

        Constraints: Tag values are case-sensitive and accept a maximum of 255 Unicode characters.

# `public `Guzzle\Service\Resource\Model``
`createDhcpOptions( array $args = array() )`

Executes the CreateDhcpOptions operation.

Creates a set of DHCP options for your VPC. After creating the set, you must associate it with the VPC, causing all existing and new instances that you launch in the VPC to use this set of DHCP options. The following are the individual DHCP options you can specify. For more information about the options, see RFC 2132.

- domain-name-servers - The IP addresses of up to four domain name servers, or AmazonProvidedDNS . The default DHCP option set specifies AmazonProvidedDNS . If specifying more than one domain name server, specify the IP addresses in a single parameter, separated by commas.
- domain-name - If you're using AmazonProvidedDNS in us-east-1 , specify ec2.internal . If you're using AmazonProvidedDNS in another region, specify region.compute.internal (for example, ap-northeast-1.compute.internal ). Otherwise, specify a domain name (for example, MyCompany.com ). Important: Some Linux operating systems accept multiple domain names separated by spaces. However, Windows and other Linux operating systems treat the value as a single domain, which results in unexpected behavior. If your DHCP options set is associated with a VPC that has instances with multiple operating systems, specify only one domain name.
- ntp-servers - The IP addresses of up to four Network Time Protocol (NTP) servers.
- netbios-name-servers - The IP addresses of up to four NetBIOS name servers.
- netbios-node-type - The NetBIOS node type (1, 2, 4, or 8). We recommend that you specify 2 (broadcast and multicast are not currently supported). For more information about these node types, see RFC 2132.

Your VPC automatically starts out with a set of DHCP options that includes only a DNS server that we provide (AmazonProvidedDNS). If you create a set of options, and if your VPC has an Internet gateway, make sure to set the domain-name-servers option either to AmazonProvidedDNS or to a domain name server of your choice. For more information about DHCP options, see DHCP Options Sets in the Amazon Virtual Private Cloud User Guide.

      ));

#### Parameters

$args
  `array`
  $arg Associative array containing the following keys (required keys are bold):
  - DryRun => (bool)

    Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

  - InstanceId => (string)

    The ID of the instance.

  - Name => (string)

    A name for the new image.

    Constraints: 3-128 alphanumeric characters, parentheses (()), square brackets ([]), spaces ( ), periods (.), slashes (/), dashes (-), single quotes ('), at-signs (@), or underscores(_)

  - Description => (string)

    A description for the new image.

  - NoReboot => (bool)

    By default, this parameter is set to false, which means Amazon EC2 attempts to shut down the instance cleanly before image creation and then reboots the instance. When the parameter is set to true, Amazon EC2 doesn't shut down the instance before creating the image. When this option is used, file system integrity on the created image can't be guaranteed.

  - BlockDeviceMappings => (array<associative-array>)

    Information about one or more block device mappings.

    - (associative-array)

      Describes a block device mapping.

      - VirtualName => (string)

        The virtual device name (ephemeralN). Instance store volumes are numbered starting from 0. An instance type with 2 available instance store volumes can specify mappings for ephemeral0 and ephemeral1.The number of available instance store volumes depends on the instance type. After you connect to the instance, you must mount the volume.

        Constraints: For M3 instances, you must specify instance store volumes in the block device mapping for the instance. When you launch an M3 instance, we ignore any instance store volumes specified in the block device mapping for the AMI.

      - DeviceName => (string)

        The device name exposed to the instance (for example, /dev/sdh or xvdh).

      - Ebs => (associative-array)

        Parameters used to automatically set up EBS volumes when the instance is launched.

        - SnapshotId => (string)

          The ID of the snapshot.

        - VolumeSize => (int)

          The size of the volume, in GiB.

          Constraints: 1-1024 for standard volumes, 1-16384 for gp2 volumes, and 4-16384 for io1 volumes. If you specify a snapshot, the volume size must be equal to or larger than the snapshot size.

          Default: If you're creating the volume from a snapshot and don't specify a volume size, the default is the snapshot size.

        - DeleteOnTermination => (bool)

          Indicates whether the EBS volume is deleted on instance termination.

        - VolumeType => (string: standard | io1 | gp2 )

          The volume type. gp2 for General Purpose (SSD) volumes, io1 for Provisioned IOPS (SSD) volumes, and standard for Magnetic volumes.

          Default: standard

        - Iops => (int)

          The number of I/O operations per second (IOPS) that the volume supports. For Provisioned IOPS (SSD) volumes, this represents the number of IOPS that are provisioned for the volume. For General Purpose (SSD) volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting. For more information on General Purpose (SSD) baseline performance, I/O credits, and bursting, see Amazon EBS Volume Types in the Amazon Elastic Compute Cloud User Guide.

          Constraint: Range is 100 to 20000 for Provisioned IOPS (SSD) volumes and 3 to 10000 for General Purpose (SSD) volumes.

          Condition: This parameter is required for requests to create io1 volumes; it is not used in requests to create standard or gp2 volumes.

        - Encrypted => (bool)

          Indicates whether the EBS volume is encrypted. Encrypted Amazon EBS volumes may only be attached to instances that support Amazon EBS encryption.

# `public `Guzzle\Service\Resource\Model``
`createNetworkAclEntry( array $args = array() )`

Executes the CreateNetworkAclEntry operation.

Creates an entry (a rule) in a network ACL with the specified rule number. Each network ACL has a set of numbered ingress rules and a separate set of numbered egress rules. When determining whether a packet should be allowed in or out of a subnet associated with the ACL, we process the entries in the ACL according to the rule numbers, in ascending order. Each network ACL has a set of ingress rules and a separate set of egress rules.

We recommend that you leave room between the rule numbers (for example, 100, 110, 120, ...), and not number them one right after the other (for example, 101, 102, 103, ...). This makes it easier to add a rule between existing ones without having to renumber the rules.

After you add an entry, you can't modify it; you must either replace it, or create an entry and delete the old one.

For more information about network ACLs, see Network ACLs in the Amazon Virtual Private Cloud User Guide.

          The number of months remaining in the reservation. For example, 2 is the second to the last month before the capacity reservation expires.

        - Price => (int)

          The fixed price for the term.

          A specific price schedule is always in effect, but only one price schedule can be active at any time. Take, for example, a Reserved Instance listing that has five months remaining in its term. When you specify price schedules for five months and two months, this means that schedule 1, covering the first three months of the remaining term, will be active during months 5, 4, and 3. Then schedule 2, covering the last two months of the term, will be active for months 2 and 1.

# `public `Guzzle\Service\Resource\Model``
`createRoute( array $args = array() )`

Executes the CreateRoute operation.

Creates a route in a route table within a VPC.

You must specify one of the following targets: Internet gateway or virtual private gateway, NAT instance, VPC peering connection, or network interface.

When determining how to route traffic, we use the route with the most specific match. For example, let's say the traffic is destined for 192.0.2.3 , and the route table includes the following two routes:

- 192.0.2.0/24 (goes to some target A)

- 192.0.2.0/28 (goes to some target B)

Both routes apply to the traffic destined for 192.0.2.3 . However, the second route in the list covers a smaller number of IP addresses and is therefore more specific, so we use that route to determine where to target the traffic.

For more information about route tables, see Route Tables in the Amazon Virtual Private Cloud User Guide.

`createSecurityGroup( array $args = array() )`

Executes the CreateSecurityGroup operation.

Creates a security group.

A security group is for use with instances either in the EC2-Classic platform or in a specific VPC. For more information, see Amazon EC2 Security Groups in the Amazon Elastic Compute Cloud User Guide and Security Groups for Your VPC in the Amazon Virtual Private Cloud User Guide.

EC2-Classic: You can have up to 500 security groups.

EC2-VPC: You can create up to 100 security groups per VPC.

When you create a security group, you specify a friendly name of your choice. You can have a security group for use in EC2-Classic with the same name as a security group for use in a VPC. However, you can't have two security groups for use in EC2-Classic with the same name or two security groups for use in a VPC with the same name.

You have a default security group for use in EC2-Classic and a default security group for use in your VPC. If you don't specify a security group when you launch an instance, the instance is launched into the appropriate default security group. A default security group includes a default rule that grants instances unrestricted network access to each other.

You can add or remove rules from your security groups using AuthorizeSecurityGroupIngress, AuthorizeSecurityGroupEgress, RevokeSecurityGroupIngress, and RevokeSecurityGroupEgress.

# `public `Guzzle\Service\Resource\Model``
`createSnapshot( array $args = array() )`

Executes the CreateSnapshot operation.

Creates a snapshot of an EBS volume and stores it in Amazon S3. You can use snapshots for backups, to make copies of EBS volumes, and to save data before shutting down an instance.

When a snapshot is created, any AWS Marketplace product codes that are associated with the source volume are propagated to the snapshot.

You can take a snapshot of an attached volume that is in use. However, snapshots only capture data that has been written to your EBS volume at the time the snapshot command is issued; this may exclude any data that has been cached by any applications or the operating system. If you can pause any file systems on the volume long enough to take a snapshot, your snapshot should be complete. However, if you cannot pause all file writes to the volume, you should unmount the volume from within the instance, issue the snapshot command, and then remount the volume to ensure a consistent and complete snapshot. You may remount and use your volume while the snapshot status is pending .

To create a snapshot for EBS volumes that serve as root devices, you should stop the instance before taking the snapshot.

Snapshots that are taken from encrypted volumes are automatically encrypted. Volumes that are created from encrypted snapshots are also automatically encrypted. Your encrypted volumes and any associated snapshots always remain protected.

For more information, see Amazon Elastic Block Store and Amazon EBS Encryption in the Amazon Elastic Compute Cloud User Guide.

#### Examples

- Basic formatting example

      $result = $client->createSnapshot(array(
          'DryRun' => true || false,
          // VolumeId is required
          'VolumeId' => 'string',
          'Description' => 'string',
      ));

#### Parameters

$args
  `array`
  $arg Associative array containing the following keys (required keys are bold):
  - DryRun => (bool)

    Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

  - VolumeId => (string)

    The ID of the EBS volume.

  - Description => (string)

    A description for the snapshot.

#### Returns

``Guzzle\Service\Resource\Model``
Returns a response Model object

- VolumeId => (string)

  The ID of the volume that was used to create the snapshot.

- State => (string)

  The snapshot state.

- StateMessage => (string)

  Encrypted Amazon EBS snapshots are copied asynchronously. If a snapshot copy operation fails (for example, if the proper AWS Key Management Service (AWS KMS) permissions are not obtained) this field displays error state details to help you diagnose why the error occurred. This parameter is only returned by the DescribeSnapshots API operation.

- StartTime => (string)

  The time stamp when the snapshot was initiated.

- Progress => (string)

  The progress of the snapshot, as a percentage.

- OwnerId => (string)

  The AWS account ID of the EBS snapshot owner.

- KmsKeyId => (string)

  The full ARN of the AWS Key Management Service (AWS KMS) customer master key (CMK) that was used to protect the volume encryption key for the parent volume.

- DataEncryptionKeyId => (string)

  The data encryption key identifier for the snapshot. This value is a unique identifier that corresponds to the data encryption key that was used to encrypt the original volume or snapshot copy. Because data encryption keys are inherited by volumes created from snapshots, and vice versa, if snapshots share the same data encryption key identifier, then they belong to the same volume/snapshot lineage. This parameter is only returned by the DescribeSnapshots API operation.

# `public `Guzzle\Service\Resource\Model``
`createSpotDatafeedSubscription( array $args = array() )`

Executes the CreateSpotDatafeedSubscription operation.

  `array`
  $arg Associative array containing the following keys (required keys are bold):
  - DryRun => (bool)

    Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

# `public `Guzzle\Service\Resource\Model``
`createSubnet( array $args = array() )`

Executes the CreateSubnet operation.

Creates a subnet in an existing VPC.

When you create each subnet, you provide the VPC ID and the CIDR block you want for the subnet. After you create a subnet, you can't change its CIDR block. The subnet's CIDR block can be the same as the VPC's CIDR block (assuming you want only a single subnet in the VPC), or a subset of the VPC's CIDR block. If you create more than one subnet in a VPC, the subnets' CIDR blocks must not overlap. The smallest subnet (and VPC) you can create uses a /28 netmask (16 IP addresses), and the largest uses a /16 netmask (65,536 IP addresses).

AWS reserves both the first four and the last IP address in each subnet's CIDR block. They're not available for use.

If you add more than one subnet to a VPC, they're set up in a star topology with a logical router in the middle.

If you launch an instance in a VPC using an Amazon EBS-backed AMI, the IP address doesn't change if you stop and restart the instance (unlike a similar instance launched outside a VPC, which gets a new IP address when restarted). It's therefore possible to have a subnet with no running instances (they're all stopped), but no remaining IP addresses available.

For more information about subnets, see Your VPC and Subnets in the Amazon Virtual Private Cloud User Guide.

#### Examples

- Basic formatting example

      $result = $client->createSubnet(array(
          'DryRun' => true || false,

# `public `Guzzle\Service\Resource\Model``
`describeSnapshots( array $args = array() )`

Executes the DescribeSnapshots operation.

Describes one or more of the EBS snapshots available to you. Available snapshots include public snapshots available for any AWS account to launch, private snapshots that you own, and private snapshots owned by another AWS account but for which you've been given explicit create volume permissions.

The create volume permissions fall into the following categories:

- public: The owner of the snapshot granted create volume permissions for the snapshot to the all group. All AWS accounts have create volume permissions for these snapshots.
- explicit: The owner of the snapshot granted create volume permissions to a specific AWS account.
- implicit: An AWS account has implicit create volume permissions for all snapshots it owns.

The list of snapshots returned can be modified by specifying snapshot IDs, snapshot owners, or AWS accounts with create volume permissions. If no options are specified, Amazon EC2 returns all snapshots for which you have create volume permissions.

If you specify one or more snapshot IDs, only snapshots that have the specified IDs are returned. If you specify an invalid snapshot ID, an error is returned. If you specify a snapshot ID for which you do not have access, it is not included in the returned results.

If you specify one or more snapshot owners, only snapshots from the specified owners and for which you have access are returned. The results can include the AWS account IDs of the specified owners, amazon for snapshots owned by Amazon, or self for snapshots that you own.

If you specify a list of restorable users, only snapshots with create snapshot permissions for those users are returned. You can specify AWS account IDs (if you own the snapshots), self for snapshots for which you own or have explicit permissions, or all for public snapshots.

If you are describing a long list of snapshots, you can paginate the output to make the list more manageable. The MaxResults parameter sets the maximum number of results returned in a single page. If the list of results exceeds your MaxResults value, then that number of results is returned along with a NextToken value that can be passed to a subsequent DescribeSnapshots request to retrieve the remaining results.

For more information about EBS snapshots, see Amazon EBS Snapshots in the Amazon Elastic Compute Cloud User Guide.

#### Examples

- Basic formatting example

      $result = $client->describeSnapshots(array(
          'DryRun' => true || false,
          'SnapshotIds' => array('string', ... ),
          'OwnerIds' => array('string', ... ),
          'RestorableByUserIds' => array('string', ... ),
          'Filters' => array(
              array(
                  'Name' => 'string',
                  'Values' => array('string', ... ),
              ),
              // ... repeated
          ),
          'NextToken' => 'string',
          'MaxResults' => integer,
      ));

#### Parameters

$args
  `array`
  $arg Associative array containing the following keys (required keys are bold):
  - DryRun => (bool)

    Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

  - SnapshotIds => (array<string>)

    One or more snapshot IDs.

    Default: Describes snapshots for which you have launch permissions.

  - OwnerIds => (array<string>)

    Returns the snapshots owned by the specified owner. Multiple owners can be specified.

  - RestorableByUserIds => (array<string>)

    One or more AWS accounts IDs that can create volumes from the snapshot.

  - Filters => (array<associative-array>)

    One or more filters.

    - description - A description of the snapshot.

    - owner-alias - The AWS account alias (for example, amazon) that owns the snapshot.

    - owner-id - The ID of the AWS account that owns the snapshot.

    - progress - The progress of the snapshot, as a percentage (for example, 80%).

    - snapshot-id - The snapshot ID.

    - start-time - The time stamp when the snapshot was initiated.

    - status - The status of the snapshot (pending | completed | error).

    - tag:key=value - The key/value combination of a tag assigned to the resource.

    - tag-key - The key of a tag assigned to the resource. This filter is independent of the tag-value filter. For example, if you use both the filter "tag-key=Purpose" and the filter "tag-value=X", you get any resources assigned both the tag key Purpose (regardless of what the tag's value is), and the tag value X (regardless of what the tag's key is). If you want to list only resources where Purpose is X, see the tag:key=value filter.

    - tag-value - The value of a tag assigned to the resource. This filter is independent of the tag-key filter.

    - volume-id - The ID of the volume the snapshot is for.

    - volume-size - The size of the volume, in GiB.

    - (associative-array)

      A filter name and value pair that is used to return a more specific list of results. Filters can be used to match a set of resources by various criteria, such as tags, attributes, or IDs.

      - Name => (string)

        The name of the filter. Filter names are case-sensitive.

      - Values => (array<string>)

        One or more filter values. Filter values are case-sensitive.

  - NextToken => (string)

    The NextToken value returned from a previous paginated DescribeSnapshots request where MaxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the NextToken value. This value is null when there are no more results to return.

  - MaxResults => (int)

    The maximum number of snapshot results returned by DescribeSnapshots in paginated output. When this parameter is used, DescribeSnapshots only returns MaxResults results in a single page along with a NextToken response element. The remaining results of the initial request can be seen by sending another DescribeSnapshots request with the returned NextToken value. This value can be between 5 and 1000; if MaxResults is given a value larger than 1000, only 1000 results are returned. If this parameter is not used, then DescribeSnapshots returns all results. You cannot specify this parameter and the snapshot IDs parameter in the same request.

#### Returns

``Guzzle\Service\Resource\Model``
Returns a response Model object

- Snapshots => (array<associative-array>)

  Information about the snapshots.

  - (associative-array)

      Encrypted Amazon EBS snapshots are copied asynchronously. If a snapshot copy operation fails (for example, if the proper AWS Key Management Service (AWS KMS) permissions are not obtained) this field displays error state details to help you diagnose why the error occurred. This parameter is only returned by the DescribeSnapshots API operation.

    - StartTime => (string)

      The time stamp when the snapshot was initiated.

    - Progress => (string)

      The progress of the snapshot, as a percentage.

    - Tags => (array<associative-array>)

      Any tags assigned to the snapshot.

      - (associative-array)

        Describes a tag.

        - Key => (string)

          The key of the tag.

    - DataEncryptionKeyId => (string)

      The data encryption key identifier for the snapshot. This value is a unique identifier that corresponds to the data encryption key that was used to encrypt the original volume or snapshot copy. Because data encryption keys are inherited by volumes created from snapshots, and vice versa, if snapshots share the same data encryption key identifier, then they belong to the same volume/snapshot lineage. This parameter is only returned by the DescribeSnapshots API operation.

- NextToken => (string)

  The NextToken value to include in a future DescribeSnapshots request. When the results of a DescribeSnapshots request exceed MaxResults, this value can be used to retrieve the next page of results. This value is null when there are no more results to return.

# `public `Guzzle\Service\Resource\Model``
`describeSpotInstanceRequests( array $args = array() )`

Executes the DescribeSpotInstanceRequests operation.

Describes the Spot instance requests that belong to your account. Spot instances are instances that Amazon EC2 launches when the bid price that you specify exceeds the current Spot price. Amazon EC2 periodically sets the Spot price based on available Spot instance capacity and current Spot instance requests. For more information, see Spot Instance Requests in the Amazon Elastic Compute Cloud User Guide.

You can use DescribeSpotInstanceRequests to find a running Spot instance by examining the response. If the status of the Spot instance is fulfilled , the instance ID appears in the response and contains the identifier of the instance. Alternatively, you can use DescribeInstances with a filter to look for instances where the instance lifecycle is spot .

# `public `Guzzle\Service\Resource\Model``
`describeVolumeStatus( array $args = array() )`

Executes the DescribeVolumeStatus operation.

Describes the status of the specified volumes. Volume status provides the result of the checks performed on your volumes to determine events that can impair the performance of your volumes. The performance of a volume can be affected if an issue occurs on the volume's underlying host. If the volume's underlying host experiences a power outage or system issue, after the system is restored, there could be data inconsistencies on the volume. Volume events notify you if this occurs. Volume actions notify you if any action needs to be taken in response to the event.

The DescribeVolumeStatus operation provides the following information about the specified volumes:

Status: Reflects the current status of the volume. The possible values are ok , impaired , warning , or insufficient-data . If all checks pass, the overall status of the volume is ok . If the check fails, the overall status is impaired . If the status is insufficient-data , then the checks may still be taking place on your volume at the time. We recommend that you retry the request. For more information on volume status, see Monitoring the Status of Your Volumes.

Events: Reflect the cause of a volume status and may require you to take action. For example, if your volume returns an impaired status, then the volume event might be potential-data-inconsistency . This means that your volume has been affected by an issue with the underlying host, has all I/O operations disabled, and may have inconsistent data.

Actions: Reflect the actions you may have to take in response to an event. For example, if the status of the volume is impaired and the volume event shows potential-data-inconsistency , then the action shows enable-volume-io . This means that you may want to enable the I/O operations for the volume by calling the EnableVolumeIO action and then check the volume for data consistency.

Volume status is based on the volume status checks, and does not reflect the volume state. Therefore, volume status does not indicate volumes in the error state (for example, when a volume is incapable of accepting I/O.)

#### Examples

- Basic formatting example

      $result = $client->describeVolumeStatus(array(
          'DryRun' => true || false,
          'VolumeIds' => array('string', ... ),
          'Filters' => array(
              array(
                  'Name' => 'string',
                  'Values' => array('string', ... ),
              ),
              // ... repeated
          ),
          'NextToken' => 'string',
          'MaxResults' => integer,
      ));

#### Parameters

$args

`detachVolume( array $args = array() )`

Executes the DetachVolume operation.

Detaches an EBS volume from an instance. Make sure to unmount any file systems on the device within your operating system before detaching the volume. Failure to do so results in the volume being stuck in a busy state while detaching.

If an Amazon EBS volume is the root device of an instance, it can't be detached while the instance is running. To detach the root volume, stop the instance first.

When a volume with an AWS Marketplace product code is detached from an instance, the product code is no longer associated with the instance.

For more information, see Detaching an Amazon EBS Volume in the Amazon Elastic Compute Cloud User Guide.

#### Examples

- Basic formatting example

      $result = $client->detachVolume(array(
          'DryRun' => true || false,

# `public `Guzzle\Service\Resource\Model``
`getConsoleOutput( array $args = array() )`

Executes the GetConsoleOutput operation.

Gets the console output for the specified instance.

Instances do not have a physical monitor through which you can view their console output. They also lack physical controls that allow you to power up, reboot, or shut them down. To allow these actions, we provide them through the Amazon EC2 API and command line interface.

Instance console output is buffered and posted shortly after instance boot, reboot, and termination. Amazon EC2 preserves the most recent 64 KB output which is available for at least one hour after the most recent post.

For Linux instances, the instance console output displays the exact console output that would normally be displayed on a physical monitor attached to a computer. This output is buffered because the instance produces it and then posts it to a store where the instance's owner can retrieve it.

For Windows instances, the instance console output includes output from the EC2Config service.

#### Examples

- Basic formatting example

      $result = $client->getConsoleOutput(array(
          'DryRun' => true || false,
          // InstanceId is required

    The ID of the instance.

#### Returns

``Guzzle\Service\Resource\Model``
Returns a response Model object

- InstanceId => (string)

  The ID of the instance.

- Timestamp => (string)

# `public `Guzzle\Service\Resource\Model``
`getPasswordData( array $args = array() )`

Executes the GetPasswordData operation.

Retrieves the encrypted administrator password for an instance running Windows.

The Windows password is generated at boot if the EC2Config service plugin, Ec2SetPassword , is enabled. This usually only happens the first time an AMI is launched, and then Ec2SetPassword is automatically disabled. The password is not generated for rebundled AMIs unless Ec2SetPassword is enabled before bundling.

The password is encrypted using the key pair that you specified when you launched the instance. You must provide the corresponding key pair file.

Password generation and encryption takes a few moments. We recommend that you wait up to 15 minutes after launching an instance before trying to retrieve the generated password.

#### Examples

- Basic formatting example

      $result = $client->getPasswordData(array(
          'DryRun' => true || false,
          // InstanceId is required

# `public `Guzzle\Service\Resource\Model``
`importKeyPair( array $args = array() )`

Executes the ImportKeyPair operation.

Imports the public key from an RSA key pair that you created with a third-party tool. Compare this with CreateKeyPair, in which AWS creates the key pair and gives the keys to you (AWS keeps a copy of the public key). With ImportKeyPair, you create the key pair and give AWS just the public key. The private key is never transferred between you and AWS.

For more information about key pairs, see Key Pairs in the Amazon Elastic Compute Cloud User Guide.

#### Examples

# `public `Guzzle\Service\Resource\Model``
`modifySpotFleetRequest( array $args = array() )`

Executes the ModifySpotFleetRequest operation.

Modifies the specified Spot fleet request.

While the Spot fleet request is being modified, it is in the modifying state.

To scale up your Spot fleet, increase its target capacity. The Spot fleet launches the additional Spot instances according to the allocation strategy for the Spot fleet request. If the allocation strategy is lowestPrice , the Spot fleet launches instances using the Spot pool with the lowest price. If the allocation strategy is diversified , the Spot fleet distributes the instances across the Spot pools.

To scale down your Spot fleet, decrease its target capacity. First, the Spot fleet cancels any open bids that exceed the new target capacity. You can request that the Spot fleet terminate Spot instances until the size of the fleet no longer exceeds the new target capacity. If the allocation strategy is lowestPrice , the Spot fleet terminates the instances with the highest price per unit. If the allocation strategy is diversified , the Spot fleet terminates instances across the Spot pools. Alternatively, you can request that the Spot fleet keep the fleet at its current size, but not replace any Spot instances that are interrupted or that you terminate manually.

#### Examples

- Basic formatting example

      $result = $client->modifySpotFleetRequest(array(
          // SpotFleetRequestId is required

# `public `Guzzle\Service\Resource\Model``
`registerImage( array $args = array() )`

Executes the RegisterImage operation.

Registers an AMI. When you're creating an AMI, this is the final step you must complete before you can launch an instance from the AMI. For more information about creating AMIs, see Creating Your Own AMIs in the Amazon Elastic Compute Cloud User Guide.

For Amazon EBS-backed instances, CreateImage creates and registers the AMI in a single request, so you don't have to register the AMI yourself.

You can also use RegisterImage to create an Amazon EBS-backed Linux AMI from a snapshot of a root device volume. For more information, see Launching an Instance from a Snapshot in the Amazon Elastic Compute Cloud User Guide.

Some Linux distributions, such as Red Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server (SLES), use the EC2 billingProduct code associated with an AMI to verify subscription status for package updates. Creating an AMI from an EBS snapshot does not maintain this billing code, and subsequent instances launched from such an AMI will not be able to connect to package update infrastructure.

Similarly, although you can create a Windows AMI from a snapshot, you can't successfully launch an instance from the AMI.

To create Windows AMIs or to create AMIs for Linux operating systems that must retain AMI billing codes to work properly, see CreateImage.

If needed, you can deregister an AMI at any time. Any modifications you make to an AMI backed by an instance store volume invalidates its registration. If you make changes to an image, deregister the previous image and register the new image.

You can't register an image where a secondary (non-root) snapshot has AWS Marketplace product codes.

#### Examples

      $result = $client->registerImage(array(
          'DryRun' => true || false,

`requestSpotFleet( array $args = array() )`

Executes the RequestSpotFleet operation.

Creates a Spot fleet request.

You can submit a single request that includes multiple launch specifications that vary by instance type, AMI, Availability Zone, or subnet.

By default, the Spot fleet requests Spot instances in the Spot pool where the price per unit is the lowest. Each launch specification can include its own instance weighting that reflects the value of the instance type to your application workload.

Alternatively, you can specify that the Spot fleet distribute the target capacity across the Spot pools included in its launch specifications. By ensuring that the Spot instances in your Spot fleet are in different Spot pools, you can improve the availability of your fleet.

For more information, see Spot Fleet Requests in the Amazon Elastic Compute Cloud User Guide.

#### Parameters

$args
  `array`
  $arg Associative array containing the following keys (required keys are bold):
  - DryRun => (bool)

    Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

  - SpotPrice => (string)

    The maximum hourly price (bid) for any Spot instance launched to fulfill the request.

  - ClientToken => (string)

    Unique, case-sensitive identifier that you provide to ensure the idempotency of the request. For more information, see How to Ensure Idempotency in the Amazon Elastic Compute Cloud User Guide.

  - InstanceCount => (int)

    The maximum number of Spot instances to launch.

    Default: 1

  - Type => (string: one-time | persistent )

    The Spot instance request type.

    Default: one-time

  - ValidFrom => (string [date format]|int [unix timestamp]|\DateTime)

    The start date of the request. If this is a one-time request, the request becomes active at this date and time and remains active until all instances launch, the request expires, or the request is canceled. If the request is persistent, the request becomes active at this date and time and remains active until it expires or is canceled.

    Default: The request is effective indefinitely.

  - ValidUntil => (string [date format]|int [unix timestamp]|\DateTime)

    The end date of the request. If this is a one-time request, the request remains active until all instances launch, the request is canceled, or this date is reached. If the request is persistent, it remains active until it is canceled or this date and time is reached.

    Default: The request is effective indefinitely.

  - LaunchGroup => (string)

    The instance launch group. Launch groups are Spot instances that launch together and terminate together.

    Default: Instances are launched and terminated individually

  - AvailabilityZoneGroup => (string)

    The user-specified name for a logical grouping of bids.

    When you specify an Availability Zone group in a Spot Instance request, all Spot instances in the request are launched in the same Availability Zone. Instance proximity is maintained with this parameter, but the choice of Availability Zone is not. The group applies only to bids for Spot Instances of the same instance type. Any additional Spot instance requests that are specified with the same Availability Zone group name are launched in that same Availability Zone, as long as at least one instance from the group is still active.

    If there is no active instance running in the Availability Zone group that you specify for a new Spot instance request (all instances are terminated, the bid is expired, or the bid falls below current market), then Amazon EC2 launches the instance in any Availability Zone where the constraint can be met. Consequently, the subsequent set of Spot instances could be placed in a different zone from the original request, even if you specified the same Availability Zone group.

    Default: Instances are launched in any available Availability Zone.

  - BlockDurationMinutes => (int)

    The required duration for the Spot instances, in minutes. This value must be a multiple of 60 (60, 120, 180, 240, 300, or 360).

    The duration period starts as soon as your Spot instance receives its instance ID. At the end of the duration period, Amazon EC2 marks the Spot instance for termination and provides a Spot instance termination notice, which gives the instance a two-minute warning before it terminates.

    Note that you can't specify an Availability Zone group or a launch group if you specify a required duration.

  - LaunchSpecification => (associative-array)

    The launch specification.

    - ImageId => (string)

      The ID of the AMI.

#### Returns

``Guzzle\Service\Resource\Model``
Returns a response Model object

# `public `Guzzle\Service\Resource\Model``
`runInstances( array $args = array() )`

Executes the RunInstances operation.

Launches the specified number of instances using an AMI for which you have permissions.

When you launch an instance, it enters the pending state. After the instance is ready for you, it enters the running state. To check the state of your instance, call DescribeInstances.

If you don't specify a security group when launching an instance, Amazon EC2 uses the default security group. For more information, see Security Groups in the Amazon Elastic Compute Cloud User Guide.

[EC2-VPC only accounts] If you don't specify a subnet in the request, we choose a default subnet from your default VPC for you.

[EC2-Classic accounts] If you're launching into EC2-Classic and you don't specify an Availability Zone, we choose one for you.

Linux instances have access to the public key of the key pair at boot. You can use this key to provide secure access to the instance. Amazon EC2 public images use this feature to provide secure access without passwords. For more information, see Key Pairs in the Amazon Elastic Compute Cloud User Guide.

You can provide optional user data when launching an instance. For more information, see Instance Metadata in the Amazon Elastic Compute Cloud User Guide.

If any of the AMIs have a product code attached for which the user has not subscribed, RunInstances fails.

T2 instance types can only be launched into a VPC. If you do not have a default VPC, or if you do not specify a subnet ID in the request, RunInstances fails.

For more information about troubleshooting, see What To Do If An Instance Immediately Terminates, and Troubleshooting Connecting to Your Instance in the Amazon Elastic Compute Cloud User Guide.

# `public `Guzzle\Service\Resource\Model``
`startInstances( array $args = array() )`

Executes the StartInstances operation.

Starts an Amazon EBS-backed AMI that you've previously stopped.

Instances that use Amazon EBS volumes as their root devices can be quickly stopped and started. When an instance is stopped, the compute resources are released and you are not billed for hourly instance usage. However, your root partition Amazon EBS volume remains, continues to persist your data, and you are charged for Amazon EBS volume usage. You can restart your instance at any time. Each time you transition an instance from stopped to started, Amazon EC2 charges a full instance hour, even if transitions happen multiple times within a single hour.

Before stopping an instance, make sure it is in a state from which it can be restarted. Stopping an instance does not preserve data stored in RAM.

Performing this operation on an instance that uses an instance store as its root device returns an error.

For more information, see Stopping Instances in the Amazon Elastic Compute Cloud User Guide.

#### Examples

- Basic formatting example

      $result = $client->startInstances(array(
          // InstanceIds is required

# `public `Guzzle\Service\Resource\Model``
`stopInstances( array $args = array() )`

Executes the StopInstances operation.

Stops an Amazon EBS-backed instance. Each time you transition an instance from stopped to started, Amazon EC2 charges a full instance hour, even if transitions happen multiple times within a single hour.

You can't start or stop Spot Instances.

Instances that use Amazon EBS volumes as their root devices can be quickly stopped and started. When an instance is stopped, the compute resources are released and you are not billed for hourly instance usage. However, your root partition Amazon EBS volume remains, continues to persist your data, and you are charged for Amazon EBS volume usage. You can restart your instance at any time.

Before stopping an instance, make sure it is in a state from which it can be restarted. Stopping an instance does not preserve data stored in RAM.

Performing this operation on an instance that uses an instance store as its root device returns an error.

You can stop, start, and terminate EBS-backed instances. You can only terminate instance store-backed instances. What happens to an instance differs if you stop it or terminate it. For example, when you stop an instance, the root device and any other devices attached to the instance persist. When you terminate an instance, the root device and any other devices attached during the instance launch are automatically deleted. For more information about the differences between stopping and terminating instances, see Instance Lifecycle in the Amazon Elastic Compute Cloud User Guide.

For more information about troubleshooting, see Troubleshooting Stopping Your Instance in the Amazon Elastic Compute Cloud User Guide.

#### Examples

- Basic formatting example

      $result = $client->stopInstances(array(

#### Parameters

$args
  `array`
  $arg Associative array containing the following keys (required keys are bold):
  - DryRun => (bool)

    Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

  - InstanceIds => (array<string>)

    One or more instance IDs.

  - Force => (bool)

    Forces the instances to stop. The instances do not have an opportunity to flush file system caches or file system metadata. If you use this option, you must perform file system check and repair procedures. This option is not recommended for Windows instances.

    Default: false

#### Returns

# `public `Guzzle\Service\Resource\Model``
`terminateInstances( array $args = array() )`

Executes the TerminateInstances operation.

Shuts down one or more instances. This operation is idempotent; if you terminate an instance more than once, each call succeeds.

Terminated instances remain visible after termination (for approximately one hour).

By default, Amazon EC2 deletes all EBS volumes that were attached when the instance launched. Volumes attached after instance launch continue running.

You can stop, start, and terminate EBS-backed instances. You can only terminate instance store-backed instances. What happens to an instance differs if you stop it or terminate it. For example, when you stop an instance, the root device and any other devices attached to the instance persist. When you terminate an instance, any attached EBS volumes with the DeleteOnTermination block device mapping parameter set to true are automatically deleted.
