See ‘aws help’ for descriptions of global parameters.

Synopsis

  create-node
[--client-request-token <value>]
--network-id <value>
[--member-id <value>]
--node-configuration <value>
[--tags <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--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.

--network-id (string)

The unique identifier of the network for the node.

Ethereum public networks have the following NetworkId s:

• n-ethereum-mainnet

• n-ethereum-rinkeby

• n-ethereum-ropsten

--member-id (string)

The unique identifier of the member that owns this node.

Applies only to Hyperledger Fabric.

--node-configuration (structure)

The properties of a node configuration.

InstanceType -> (string)

The Amazon Managed Blockchain instance type for the node.

AvailabilityZone -> (string)

The Availability Zone in which the node exists. Required for Ethereum nodes.

LogPublishingConfiguration -> (structure)

Configuration properties for logging events associated with a peer node on a Hyperledger Fabric network on Managed Blockchain.

Fabric -> (structure)

Configuration properties for logging events associated with a node that is owned by a member of a Managed Blockchain network using the Hyperledger Fabric framework.

ChaincodeLogs -> (structure)

Configuration properties for logging events associated with chaincode execution on a peer node. Chaincode logs contain the results of instantiating, invoking, and querying the chaincode. A peer can run multiple instances of chaincode. When enabled, a log stream is created for all chaincodes, with an individual log stream for each chaincode.

Cloudwatch -> (structure)

Parameters for publishing logs to Amazon CloudWatch Logs.

Enabled -> (boolean)

Indicates whether logging is enabled.

PeerLogs -> (structure)

Configuration properties for a peer node log. Peer node logs contain messages generated when your client submits transaction proposals to peer nodes, requests to join channels, enrolls an admin peer, and lists the chaincode instances on a peer node.

Cloudwatch -> (structure)

Parameters for publishing logs to Amazon CloudWatch Logs.

Enabled -> (boolean)

Indicates whether logging is enabled.

StateDB -> (string)

The state database that the node uses. Values are LevelDB or CouchDB . When using an Amazon Managed Blockchain network with Hyperledger Fabric version 1.4 or later, the default is CouchDB .

Applies only to Hyperledger Fabric.

JSON Syntax:

{
  "InstanceType": "string",
  "AvailabilityZone": "string",
  "LogPublishingConfiguration": {
    "Fabric": {
      "ChaincodeLogs": {
        "Cloudwatch": {
          "Enabled": true|false
        }
      },
      "PeerLogs": {
        "Cloudwatch": {
          "Enabled": true|false
        }
      }
    }
  },
  "StateDB": "LevelDB"|"CouchDB"
}

--tags (map)

Tags to assign to the node. Each tag consists of a key and optional value.

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.

For more information about tags, see Tagging Resources in the Amazon Managed Blockchain Ethereum Developer Guide , or Tagging Resources in the Amazon Managed Blockchain Hyperledger Fabric Developer Guide .

key -> (string)

value -> (string)

Shorthand Syntax:

KeyName1=string,KeyName2=string

JSON Syntax:

{"string": "string"
  ...}

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. 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.

Output

NodeId -> (string)

The unique identifier of the node.
