      "MemberId" : String,
      "NetworkId" : String,
      "NodeConfiguration" : NodeConfiguration
    }
}

YAML

Type: AWS::ManagedBlockchain::Node
Properties:
  MemberId: String
  NetworkId: String
  NodeConfiguration: 
    NodeConfiguration

Properties

MemberId

The unique identifier of the member to which the node belongs. Applies only to Hyperledger Fabric.

Return values

Ref

When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns the node ID.

For more information about using the Ref function, see Ref.

Fn::GetAtt

The Fn::GetAtt intrinsic function returns a value for a specified attribute of this type. The following are the available attributes and sample return values.

For more information about using the Fn::GetAtt intrinsic function, see Fn::GetAtt.

Arn

The Amazon Resource Name (ARN) of the node.

MemberId

The unique identifier of the member in which the node is created. Applies only to Hyperledger Fabric.

NetworkId

The unique identifier of the network that the node is in.

NodeId

The unique identifier of the node.
