See 'aws help' for descriptions of global parameters.


[--client-request-token <value>]
--invitation-id <value>
--network-id <value>
--member-configuration <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


--client-request-token (string)

A unique, case-sensitive identifier that you provide to ensure the idempotency of the operation. An idempotent operation completes no more than one time. This identifier is required only if you make a service request directly using an HTTP client. It is generated automatically if you use an AWS SDK or the AWS CLI.

--invitation-id (string)

The unique identifier of the invitation that is sent to the member to join the network.

--network-id (string)

The unique identifier of the network in which the member is created.

--member-configuration (structure)

Member configuration parameters.

Name -> (string)

The name of the member.

Description -> (string)

An optional description of the member.

FrameworkConfiguration -> (structure)

Configuration properties of the blockchain framework relevant to the member.

Fabric -> (structure)

Attributes of Hyperledger Fabric for a member on a Managed Blockchain network that uses Hyperledger Fabric.

AdminUsername -> (string)

The user name for the member's initial administrative user.

AdminPassword -> (string)

The password for the member's initial administrative user. The AdminPassword must be at least eight characters long and no more than 32 characters. It must contain at least one uppercase letter, one lowercase letter, and one digit. It cannot have a single quotation mark (‘), a double quotation marks (“), a forward slash(/), a backward slash(), @, or a space.

LogPublishingConfiguration -> (structure)

Configuration properties for logging events associated with a member of a Managed Blockchain network.

Fabric -> (structure)

Configuration properties for logging events associated with a member of a Managed Blockchain network using the Hyperledger Fabric framework.

CaLogs -> (structure)

Configuration properties for logging events associated with a member's Certificate Authority (CA). CA logs help you determine when a member in your account joins the network, or when new peers register with a member CA.

Cloudwatch -> (structure)

Parameters for publishing logs to Amazon CloudWatch Logs.

Enabled -> (boolean)

Indicates whether logging is enabled.

Tags -> (map)

Tags assigned to the member. Tags consist of a key and optional value. For more information about tags, see Tagging Resources in the Amazon Managed Blockchain Hyperledger Fabric Developer Guide .

When specifying tags during creation, you can specify multiple key-value pairs in a single request, with an overall maximum of 50 tags added to each resource.

key -> (string)

value -> (string)

KmsKeyArn -> (string)

The Amazon Resource Name (ARN) of the customer managed key in AWS Key Management Service (AWS KMS) to use for encryption at rest in the member. This parameter is inherited by any nodes that this member creates.

Use one of the following options to specify this parameter:

  • Undefined or empty string - The member uses an AWS owned KMS key for encryption by default.
  • A valid symmetric customer managed KMS key - The member uses the specified key for encryption. Amazon Managed Blockchain doesn't support asymmetric keys. For more information, see Using symmetric and asymmetric keys in the AWS Key Management Service Developer Guide . The following is an example of a KMS key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.


MemberId -> (string)

The unique identifier of the member.
