Gestisci le policy basate sulle risorse di DynamoDB utilizzando AWS Command Line Interface   v2

Creare una tabella con una policy di risorse.

# Step 1: Create a DynamoDB table
aws dynamodb create-table \
    --table-name MusicCollection \
    --attribute-definitions \
        AttributeName=Artist,AttributeType=S \
        AttributeName=SongTitle,AttributeType=S \
    --key-schema \
        AttributeName=Artist,KeyType=HASH \
        AttributeName=SongTitle,KeyType=RANGE \
    --billing-mode PAY_PER_REQUEST

# Step 2: Create a resource-based policy document
cat > policy.json << 'EOF'
{
  "Version":"2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::123456789012:role/DynamoDBReadOnly"
      },
      "Action": [
        "dynamodb:GetItem",
        "dynamodb:BatchGetItem",
        "dynamodb:Query",
        "dynamodb:Scan"
      ],
      "Resource": "arn:aws:dynamodb:us-west-2:123456789012:table/MusicCollection"
    }
  ]
}
EOF

# Step 3: Attach the resource-based policy to the table
aws dynamodb put-resource-policy \
    --resource-arn arn:aws:dynamodb:us-west-2:123456789012:table/MusicCollection \
    --policy file://policy.json

Ottenere una policy di risorse.

# Get the resource-based policy attached to a table
aws dynamodb get-resource-policy \
    --resource-arn arn:aws:dynamodb:us-west-2:123456789012:table/MusicCollection

Aggiornare una policy di risorse.

# Step 1: Create an updated policy document
cat > updated-policy.json << 'EOF'
{
  "Version":"2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": [
          "arn:aws:iam::123456789012:role/DynamoDBReadOnly",
          "arn:aws:iam::123456789012:role/DynamoDBAnalytics"
        ]
      },
      "Action": [
        "dynamodb:GetItem",
        "dynamodb:BatchGetItem",
        "dynamodb:Query",
        "dynamodb:Scan"
      ],
      "Resource": "arn:aws:dynamodb:us-west-2:123456789012:table/MusicCollection"
    }
  ]
}
EOF

# Step 2: Update the resource-based policy on the table
aws dynamodb put-resource-policy \
    --resource-arn arn:aws:dynamodb:us-west-2:123456789012:table/MusicCollection \
    --policy file://updated-policy.json

Eliminare una policy di risorse.

# Delete the resource-based policy from a table
aws dynamodb delete-resource-policy \
    --resource-arn arn:aws:dynamodb:us-west-2:123456789012:table/MusicCollection
