# 自我管理 Kafka 叢集的 CreateReplicator API 範例
<a name="msk-replicator-external-api-examples"></a>

## 轉送複寫 （自我管理 Kafka 到 MSK Express)
<a name="msk-replicator-external-forward"></a>

使用下列 AWS CLI 命令來建立複寫器，將資料從自我管理的 Kafka 叢集複寫到 Amazon MSK Express 叢集。

```
aws kafka create-replicator \
  --replicator-name my-selfmanaged-to-msk-replicator \
  --description "Replicating from self-managed Kafka to MSK Express" \
  --service-execution-role-arn arn:aws:iam::123456789012:role/MSKReplicatorRole \
  --kafka-clusters '[
    {
      "apacheKafkaCluster": {
        "bootstrapBrokerString": "broker1:9094,broker2:9094,broker3:9094",
        "apacheKafkaClusterId": "<self-managed-cluster-id>"
      },
      "clientAuthentication": {
        "saslScram": {
          "mechanism": "SHA256",
          "secretArn": "arn:aws:secretsmanager:us-east-1:123456789012:secret:kafka-scram-creds"
        }
      },
      "encryptionInTransit": {
        "encryptionType": "TLS",
        "rootCaCertificate": "arn:aws:secretsmanager:us-east-1:123456789012:secret:kafka-scram-creds"
      },
      "vpcConfig": {
        "subnetIds": ["subnet-aaa","subnet-bbb","subnet-ccc"],
        "securityGroupIds": ["sg-xxxxxxxxxxxxxxxxx"]
      }
    },
    {
      "amazonMskCluster": {
        "mskClusterArn": "arn:aws:kafka:us-east-1:123456789012:cluster/msk-express/xxx"
      },
      "vpcConfig": {
        "subnetIds": ["subnet-ddd","subnet-eee","subnet-fff"],
        "securityGroupIds": ["sg-yyyyyyyyy"]
      }
    }]' \
  --replication-info-list '[{
    "sourceKafkaClusterId": "<self-managed-cluster-id>",
    "targetKafkaClusterArn": "arn:aws:kafka:us-east-1:123456789012:cluster/msk-express/xxx",
    "targetCompressionType": "NONE",
    "topicReplication": {
      "topicsToReplicate": [".*"],
      "topicNameConfiguration": {"type": "IDENTICAL"},
      "startingPosition": {"type": "EARLIEST"},
      "detectAndCopyNewTopics": true,
      "copyTopicConfigurations": true,
      "copyAccessControlListsForTopics": true
    },
    "consumerGroupReplication": {
      "consumerGroupsToReplicate": [".*"],
      "detectAndCopyNewConsumerGroups": true,
      "synchroniseConsumerGroupOffsets": true
    }}]'
```

## 雙向複寫範例
<a name="msk-replicator-external-bidirectional"></a>

若要為轉返功能設定雙向複寫，必須先建立正向和反向複寫器，並將 `consumerGroupOffsetSyncMode`設定為 `ENHANCED`。這可確保消費者群組位移的同步方式可支援任一方向的無縫切換。

使用`ENHANCED`偏移同步模式建立轉送複寫器 （自我管理 Kafka 到 MSK Express)：

```
aws kafka create-replicator \
  --replicator-name my-selfmanaged-to-msk-replicator \
  --description "Replicating from self-managed Kafka to MSK Express" \
  --service-execution-role-arn arn:aws:iam::123456789012:role/MSKReplicatorRole \
  --kafka-clusters '[
    {
      "apacheKafkaCluster": {
        "bootstrapBrokerString": "broker1:9094,broker2:9094,broker3:9094",
        "apacheKafkaClusterId": "<self-managed-cluster-id>"
      },
      "clientAuthentication": {
        "saslScram": {
          "mechanism": "SHA256",
          "secretArn": "arn:aws:secretsmanager:us-east-1:123456789012:secret:kafka-scram-creds"
        }
      },
      "encryptionInTransit": {
        "encryptionType": "TLS",
        "rootCaCertificate": "arn:aws:secretsmanager:us-east-1:123456789012:secret:kafka-ca-cert"
      },
      "vpcConfig": {
        "subnetIds": ["subnet-aaa","subnet-bbb","subnet-ccc"],
        "securityGroupIds": ["sg-xxxxxxxxxxxxxxxxx"]
      }
    },
    {
      "amazonMskCluster": {
        "mskClusterArn": "arn:aws:kafka:us-east-1:123456789012:cluster/msk-express/xxx"
      },
      "vpcConfig": {
        "subnetIds": ["subnet-ddd","subnet-eee","subnet-fff"],
        "securityGroupIds": ["sg-yyyyyyyyy"]
      }
    }]' \
  --replication-info-list '[{
    "sourceKafkaClusterId": "<self-managed-cluster-id>",
    "targetKafkaClusterArn": "arn:aws:kafka:us-east-1:123456789012:cluster/msk-express/xxx",
    "targetCompressionType": "NONE",
    "topicReplication": {
      "topicsToReplicate": [".*"],
      "topicNameConfiguration": {"type": "IDENTICAL"},
      "startingPosition": {"type": "EARLIEST"},
      "detectAndCopyNewTopics": true,
      "copyTopicConfigurations": true,
      "copyAccessControlListsForTopics": true
    },
    "consumerGroupReplication": {
      "consumerGroupsToReplicate": [".*"],
      "detectAndCopyNewConsumerGroups": true,
      "synchroniseConsumerGroupOffsets": true,
      "consumerGroupOffsetSyncMode": "ENHANCED"
    }}]'
```

然後使用`ENHANCED`偏移同步模式建立反向複寫器 (MSK Express 到自我管理的 Kafka)：

```
aws kafka create-replicator \
  --replicator-name my-msk-to-selfmanaged-replicator \
  --description "Reverse replication for rollback" \
  --service-execution-role-arn arn:aws:iam::123456789012:role/MSKReplicatorRole \
  --kafka-clusters '[
    {
      "amazonMskCluster": {
        "mskClusterArn": "arn:aws:kafka:us-east-1:123456789012:cluster/msk-express/xxx"
      },
      "vpcConfig": {
        "subnetIds": ["subnet-ddd","subnet-eee","subnet-fff"],
        "securityGroupIds": ["sg-yyyyyyyyy"]
      }
    },
    {
      "apacheKafkaCluster": {
        "bootstrapBrokerString": "broker1:9094,broker2:9094,broker3:9094",
        "apacheKafkaClusterId": "<self-managed-cluster-id>"
      },
      "clientAuthentication": {
        "saslScram": {
          "mechanism": "SHA256",
          "secretArn": "arn:aws:secretsmanager:us-east-1:123456789012:secret:kafka-scram-creds"
        }
      },
      "encryptionInTransit": {
        "encryptionType": "TLS",
        "rootCaCertificate": "arn:aws:secretsmanager:us-east-1:123456789012:secret:kafka-ca-cert"
      },
      "vpcConfig": {
        "subnetIds": ["subnet-aaa","subnet-bbb","subnet-ccc"],
        "securityGroupIds": ["sg-xxxxxxxxxxxxxxxxx"]
      }
    }]' \
  --replication-info-list '[{
    "sourceKafkaClusterArn": "arn:aws:kafka:us-east-1:123456789012:cluster/msk-express/xxx",
    "targetKafkaClusterId": "<self-managed-cluster-id>",
    "targetCompressionType": "NONE",
    "topicReplication": {
      "topicsToReplicate": [".*"],
      "topicNameConfiguration": {"type": "IDENTICAL"},
      "startingPosition": {"type": "LATEST"},
      "detectAndCopyNewTopics": true,
      "copyTopicConfigurations": true,
      "copyAccessControlListsForTopics": true
    },
    "consumerGroupReplication": {
      "consumerGroupsToReplicate": [".*"],
      "detectAndCopyNewConsumerGroups": true,
      "synchroniseConsumerGroupOffsets": true,
      "consumerGroupOffsetSyncMode": "ENHANCED"
    }}]'
```

## 驗證複寫器狀態
<a name="msk-replicator-external-verify"></a>

使用 CLI `describe-replicator` 命令檢查複寫器的狀態：

```
aws kafka describe-replicator \
  --replicator-arn arn:aws:kafka:us-east-1:123456789012:replicator/my-replicator/xxx
```

複寫器將繼續進行 `CREATING` → `RUNNING` 狀態。等待約 30 分鐘讓複寫器達到`RUNNING`狀態。
