create_replication_subnet_group

DatabaseMigrationService.Client.create_replication_subnet_group(**kwargs)

Creates a replication subnet group given a list of the subnet IDs in a VPC.

The VPC needs to have at least one subnet in at least two availability zones in the Amazon Web Services Region, otherwise the service will throw a ReplicationSubnetGroupDoesNotCoverEnoughAZs exception.

If a replication subnet group exists in your Amazon Web Services account, the CreateReplicationSubnetGroup action returns the following error message: The Replication Subnet Group already exists. In this case, delete the existing replication subnet group. To do so, use the DeleteReplicationSubnetGroup action. Optionally, choose Subnet groups in the DMS console, then choose your subnet group. Next, choose Delete from Actions.

Request Syntax

response = client.create_replication_subnet_group(
    ReplicationSubnetGroupIdentifier='string',
    ReplicationSubnetGroupDescription='string',
    SubnetIds=[
        'string',
    ],
    Tags=[
        {
            'Key': 'string',
            'Value': 'string',
            'ResourceArn': 'string'
        },
    ]
)

Parameters:

• ReplicationSubnetGroupIdentifier (string) –

  [REQUIRED]

  The name for the replication subnet group. This value is stored as a lowercase string.

  Constraints: Must contain no more than 255 alphanumeric characters, periods, underscores, or hyphens. Must not be “default”.

  Example: mySubnetgroup

• ReplicationSubnetGroupDescription (string) –

  [REQUIRED]

  The description for the subnet group.

• SubnetIds (list) –

  [REQUIRED]

  Two or more subnet IDs to be assigned to the subnet group.

  • (string) –

• Tags (list) –

  One or more tags to be assigned to the subnet group.

  • (dict) –

    A user-defined key-value pair that describes metadata added to an DMS resource and that is used by operations such as the following:

    • AddTagsToResource

    • ListTagsForResource

    • RemoveTagsFromResource

    • Key (string) –

      A key is the required name of the tag. The string value can be 1-128 Unicode characters in length and can’t be prefixed with “aws:” or “dms:”. The string can only contain only the set of Unicode letters, digits, white-space, ‘_’, ‘.’, ‘/’, ‘=’, ‘+’, ‘-’ (Java regular expressions: “^([\p{L}\p{Z}\p{N}_.:/=+\-]*)$”).

    • Value (string) –

      A value is the optional value of the tag. The string value can be 1-256 Unicode characters in length and can’t be prefixed with “aws:” or “dms:”. The string can only contain only the set of Unicode letters, digits, white-space, ‘_’, ‘.’, ‘/’, ‘=’, ‘+’, ‘-’ (Java regular expressions: “^([\p{L}\p{Z}\p{N}_.:/=+\-]*)$”).

    • ResourceArn (string) –

      The Amazon Resource Name (ARN) string that uniquely identifies the resource for which the tag is created.

Return type:

dict

Response Structure

• (dict) –

  • ReplicationSubnetGroup (dict) –

    The replication subnet group that was created.

    • ReplicationSubnetGroupIdentifier (string) –

    • VpcId (string) –

      The ID of the VPC.

    • SubnetGroupStatus (string) –

      The status of the subnet group.

    • Subnets (list) –

      The subnets that are in the subnet group.

      • (dict) –

        In response to a request by the DescribeReplicationSubnetGroups operation, this object identifies a subnet by its given Availability Zone, subnet identifier, and status.

        • SubnetIdentifier (string) –

          The subnet identifier.

        • SubnetAvailabilityZone (dict) –
