S3 Tables レプリケーションの設定

S3 Tables がロールを引き受けることを許可する信頼ポリシードキュメントを作成します。これを trust-policy.json として保存します。

{
  "Version": "2012-10-17"		 	 	 
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "Service": "replication.s3tables.amazonaws.com"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}
     

IAM ロールの作成:

aws iam create-role \
    --role-name S3TablesReplicationRole \
    --assume-role-policy-document file://trust-policy.json \
    --description "Role for S3 Tables replication"
     

レプリケーションアクセス許可を付与するアクセス許可ポリシーを作成します。これを replication-permissions.json として保存します。

{
    "Version": "2012-10-17",		 	 	 
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "s3tables:GetTable",
                "s3tables:GetTableMetadataLocation",
                "s3tables:GetTableMaintenanceConfiguration",
                "s3tables:GetTableData"
            ],
            "Resource": "arn:aws:s3tables:us-east-2:111122223333:bucket/amzn-s3-demo-table-bucket-source/table/*"
        },
        {
            "Effect": "Allow",
            "Action": [
                "s3tables:ListTables"
            ],
            "Resource": "arn:aws:s3tables:us-east-2:111122223333:bucket/amzn-s3-demo-table-bucket-source"
        },
        {
            "Effect": "Allow",
            "Action": [
                "s3tables:CreateTable",
                "s3tables:CreateNamespace"
            ],
            "Resource": "arn:aws:s3tables:us-east-2:444455556666:bucket/amzn-s3-demo-table-bucket-destination"
        },
        {
            "Effect": "Allow",
            "Action": [
                "s3tables:PutTableData",
                "s3tables:GetTableData",
                "s3tables:UpdateTableMetadataLocation",
                "s3tables:PutTableMaintenanceConfiguration"
            ],
            "Resource": "arn:aws:s3tables:us-east-2:444455556666:bucket/amzn-s3-demo-table-bucket-destination/table/*"
        }
    ]
}
     

アクセス許可ポリシーをロールにアタッチします:

aws iam put-role-policy \
    --role-name S3TablesReplicationRole \
    --policy-name S3TablesReplicationPermissions \
    --policy-document file://replication-permissions.json
     

(オプション) KMS 暗号化を使用する場合は、ポリシーに KMS アクセス許可を追加します。

{
  "Effect": "Allow",		 	 	 
  "Action": [
     "kms:Decrypt",
     "kms:GenerateDataKey",
     "kms:Encrypt"

  ],
  "Resource": "arn:aws:kms:us-east-1:111122223333:key/SOURCE-KEY-ID"
},
{
  "Effect": "Allow",
  "Action": [
    "kms:Decrypt",
    "kms:GenerateDataKey"
  ],
  "Resource": [
    "arn:aws:kms:us-west-2:444455556666:key/DESTINATION-KEY-ID-1"
  ]
}
     

送信先アカウントで、送信先テーブルバケットのバケットポリシーを作成します。これを destination-bucket-policy.json として保存します。

{
    "Version": "2012-10-17",		 	 	 
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::444455556666:role/cross-account-test"
            },
            "Action": [
                "s3tables:PutTableData",
                "s3tables:GetTableData",
                "s3tables:UpdateTableMetadataLocation",
                "s3tables:PutTableMaintenanceConfiguration"
            ],
            "Resource": "arn:aws:s3tables:us-east-2:111122223333:bucket/amzn-s3-demo-table-bucket-cross-account-destination/table/*"
        },
        {
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::444455556666:role/cross-account-test"
            },
            "Action": [
                "s3tables:CreateTable",
                "s3tables:CreateNamespace"
            ],
            "Resource": "arn:aws:s3tables:us-east-2:111122223333:bucket/amzn-s3-demo-table-bucket-cross-account-destination"
        }
    ]
}   

S3 Tables API を使用してポリシーを適用します。

aws s3tables put-table-bucket-policy \
    --table-bucket-arn arn:aws:s3tables:us-west-2:444455556666:bucket/amzn-s3-demo-table-bucket-cross-account-destination \
    --policy file://destination-bucket-policy.json \
    --profile destination-account
   

ソース KMS キーを変更して、S3 Tables のレプリケーションとメンテナンスを許可します。

{
  "Version": "2012-10-17",		 	 	 
  "Id": "key-consolepolicy-3",
  "Statement": [
        {
            "Sid": "allow replication to decrypt",
            "Effect": "Allow",
            "Principal": {
                "AWS": "replication_role_arn"
            },
            "Action": [
                "kms:Decrypt",
                "kms:GenerateDataKey"
            ],
            "Resource": "arn:aws:kms:us-east-1:111122223333:key/SOURCE-KEY-ID"
        },
        {
            "Sid": "allow maintenance",
            "Effect": "Allow",
            "Principal": {
                "Service": "maintenance.s3tables.amazonaws.com"
            },
            "Action": [
                "kms:Decrypt",
                "kms:GenerateDataKey"
            ],
            "Resource": "arn:aws:kms:us-east-1:111122223333:key/SOURCE-KEY-ID"
        }
  ]
}
     

同様に、送信先 KMS キーポリシーに許可を追加します

{
    "Version": "2012-10-17",		 	 	 
    "Id": "key-policy-3",
    "Statement": [
        {
            "Sid": "allow maintenance",
            "Effect": "Allow",
            "Principal": {
                "Service": "maintenance.s3tables.amazonaws.com"
            },
            "Action": [
                "kms:Decrypt",
                "kms:GenerateDataKey"
            ],
            "Resource": "arn:aws:kms:us-west-2:444455556666:key/DESTINATION-KEY-ID-1"
        },
        {
            "Sid": "allow replication to encrypt/decrypt",
            "Effect": "Allow",
            "Principal": {
                "AWS": "replication_role_arn"
            },
            "Action": [
                "kms:Encrypt",
                "kms:Decrypt",
                "kms:GenerateDataKey"
            ],
            "Resource": "arn:aws:kms:us-west-2:444455556666:key/DESTINATION-KEY-ID-1"
        }
    ]
