Client — AWS SDK for Ruby V2

You are viewing documentation for version 2 of the AWS SDK for Ruby. Version 3 documentation can be found here.

Class: Aws::ManagedBlockchain::Client Overview

An API client for Amazon Managed Blockchain. To construct a client, you need to configure a :region and :credentials.

managedblockchain = Aws::ManagedBlockchain::Client.new(
  region: region_name,
  credentials: credentials,
  )

See #initialize for a full list of supported configuration options.

Region

You can configure a default region in the following locations:

Go here for a list of supported regions.

Credentials

Default credentials are loaded automatically from the following locations:

You can also construct a credentials object from one of the following classes:

Alternatively, you configure credentials with :access_key_id and :secret_access_key:

creds = YAML.load(File.read('/path/to/secrets'))

Aws::ManagedBlockchain::Client.new(
  access_key_id: creds['access_key_id'],
  secret_access_key: creds['secret_access_key']
)

Always load your credentials from outside your application. Avoid configuring credentials statically and never commit them to source control.

Instance Method Details #create_proposal(options = {}) ⇒ Types::CreateProposalOutput

Creates a proposal for a change to the network that other members of the network can vote on, for example, a proposal to add a new member to the network. Any member can create a proposal.

#delete_member(options = {}) ⇒ Struct

Deletes a member. Deleting a member removes the member and all associated resources from the network. DeleteMember can only be called for a specified MemberId if the principal performing the action is associated with the AWS account that owns the member. In all other cases, the DeleteMember action is carried out as the result of an approved proposal to remove a member. If MemberId is the last member in a network specified by the last AWS account, the network is deleted also.

#delete_node(options = {}) ⇒ Struct

Deletes a peer node from a member that your AWS account owns. All data on the node is lost and cannot be recovered.

#list_members(options = {}) ⇒ Types::ListMembersOutput

Returns a listing of the members in a network and properties of their configurations.

#list_networks(options = {}) ⇒ Types::ListNetworksOutput

Returns information about the networks in which the current AWS account has members.

#list_proposal_votes(options = {}) ⇒ Types::ListProposalVotesOutput

Returns the listing of votes for a specified proposal, including the value of each vote and the unique identifier of the member that cast the vote.

#reject_invitation(options = {}) ⇒ Struct

Rejects an invitation to join a network. This action can be called by a principal in an AWS account that has received an invitation to create a member and join a network.

#update_member(options = {}) ⇒ Struct

Updates a member configuration with new parameters.

#update_node(options = {}) ⇒ Struct

Updates a node configuration with new parameters.

#vote_on_proposal(options = {}) ⇒ Struct

Casts a vote for a specified ProposalId on behalf of a member. The member to vote as, specified by VoterMemberId, must be in the same AWS account as the principal that calls the action.

#wait_until(waiter_name, params = {}) {|waiter| ... } ⇒ Boolean

Waiters polls an API operation until a resource enters a desired state.

Basic Usage

Waiters will poll until they are succesful, they fail by entering a terminal state, or until a maximum number of attempts are made.

# polls in a loop, sleeping between attempts client.waiter_until(waiter_name, params)

Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. You configure waiters by passing a block to #wait_until:

# poll for ~25 seconds
client.wait_until(...) do |w|
  w.max_attempts = 5
  w.delay = 5
end
Callbacks

You can be notified before each polling attempt and before each delay. If you throw :success or :failure from these callbacks, it will terminate the waiter.

started_at = Time.now
client.wait_until(...) do |w|

  # disable max attempts
  w.max_attempts = nil

  # poll for 1 hour, instead of a number of attempts
  w.before_wait do |attempts, response|
    throw :failure if Time.now - started_at > 3600
  end

end
Handling Errors

When a waiter is successful, it returns true. When a waiter fails, it raises an error. All errors raised extend from Waiters::Errors::WaiterFailed.

begin
  client.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end
#waiter_names ⇒ Array<Symbol>

Returns the list of supported waiters. The following table lists the supported waiters and the client method they call:

Waiter Name Client Method Default Delay: Default Max Attempts:
