Class: Aws::MigrationHub::Client

Inherits:
Seahorse::Client::Base show all
Defined in:
(unknown)

Overview

An API client for AWS Migration Hub. To construct a client, you need to configure a :region and :credentials.

migrationhub = Aws::MigrationHub::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:

  • ENV['AWS_REGION']
  • Aws.config[:region]

Go here for a list of supported regions.

Credentials

Default credentials are loaded automatically from the following locations:

  • ENV['AWS_ACCESS_KEY_ID'] and ENV['AWS_SECRET_ACCESS_KEY']
  • Aws.config[:credentials]
  • The shared credentials ini file at ~/.aws/credentials (more information)
  • From an instance profile when running on EC2

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:

# load credentials from disk
creds = YAML.load(File.read('/path/to/secrets'))

Aws::MigrationHub::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

#associate_created_artifact(options = {}) ⇒ Struct

Associates a created artifact of an AWS cloud resource, the target receiving the migration, with the migration task performed by a migration tool. This API has the following traits:

  • Migration tools can call the AssociateCreatedArtifact operation to indicate which AWS artifact is associated with a migration task.

  • The created artifact name must be provided in ARN (Amazon Resource Name) format which will contain information about type and region; for example: arn:aws:ec2:us-east-1:488216288981:image/ami-6d0ba87b.

  • Examples of the AWS resource behind the created artifact are, AMI's, EC2 instance, or DMS endpoint, etc.

Examples:

Request syntax with placeholder values


resp = client.associate_created_artifact({
  progress_update_stream: "ProgressUpdateStream", # required
  migration_task_name: "MigrationTaskName", # required
  created_artifact: { # required
    name: "CreatedArtifactName", # required
    description: "CreatedArtifactDescription",
  },
  dry_run: false,
})

Options Hash (options):

  • :progress_update_stream (required, String)

    The name of the ProgressUpdateStream.

  • :migration_task_name (required, String)

    Unique identifier that references the migration task.

    An ARN of the AWS resource related to the migration (e.g., AMI, EC2 instance, RDS instance, etc.)

  • :dry_run (Boolean)

    Optional boolean flag to indicate whether any effect should take place. Used to test if the caller has permission to make the call.

Returns:

  • (Struct)

    Returns an empty response.

See Also:

#associate_discovered_resource(options = {}) ⇒ Struct

Associates a discovered resource ID from Application Discovery Service (ADS) with a migration task.

Examples:

Request syntax with placeholder values

  progress_update_stream: "ProgressUpdateStream", # required
  migration_task_name: "MigrationTaskName", # required
  discovered_resource: { # required
    configuration_id: "ConfigurationId", # required
    description: "DiscoveredResourceDescription",
  },
  dry_run: false,
})

Options Hash (options):

  • :discovered_resource (required, Types::DiscoveredResource)

    Object representing a Resource.

  • :dry_run (Boolean)

    Optional boolean flag to indicate whether any effect should take place. Used to test if the caller has permission to make the call.

Returns:

  • (Struct)

    Returns an empty response.

See Also:

#create_progress_update_stream(options = {}) ⇒ Struct

Creates a progress update stream which is an AWS resource used for access control as well as a namespace for migration task names that is implicitly linked to your AWS account. It must uniquely identify the migration tool as it is used for all updates made by the tool; however, it does not need to be unique for each AWS account because it is scoped to the AWS account.

Examples:

Request syntax with placeholder values


resp = client.create_progress_update_stream({
  progress_update_stream_name: "ProgressUpdateStream", # required
  dry_run: false,
})

Options Hash (options):

  • :progress_update_stream_name (required, String)

    The name of the ProgressUpdateStream.

  • :dry_run (Boolean)

    Optional boolean flag to indicate whether any effect should take place. Used to test if the caller has permission to make the call.

Returns:

  • (Struct)

    Returns an empty response.

See Also:

#delete_progress_update_stream(options = {}) ⇒ Struct

Deletes a progress update stream, including all of its tasks, which was previously created as an AWS resource used for access control. This API has the following traits:

  • The only parameter needed for DeleteProgressUpdateStream is the stream name (same as a CreateProgressUpdateStream call).

  • The call will return, and a background process will asynchronously be doing the actual delete of the stream and all of its resources (tasks, associated resources, resource attributes, created artifacts).

  • If the stream takes time to be deleted, it might still show up on a ListProgressUpdateStreams call.

  • CreateProgressUpdateStream, ImportMigrationTask, NotifyMigrationTaskState, and all Associate[*] APIs realted to the tasks belonging to the stream will throw "InvalidInputException" if the stream of the same name is in the process of being deleted.

  • Once the stream and all of its resources are deleted, CreateProgressUpdateStream for a stream of the same name will succeed, and that stream will be an entirely new logical resource (without any resources associated with the old stream).

Examples:

Request syntax with placeholder values


resp = client.delete_progress_update_stream({
  progress_update_stream_name: "ProgressUpdateStream", # required
  dry_run: false,
})

#put_resource_attributes(options = {}) ⇒ Struct

Provides identifying details of the resource being migrated so that it can be associated in the Application Discovery Service (ADS)'s repository. This association occurs asynchronously after PutResourceAttributes returns.

Keep in mind that subsequent calls to PutResourceAttributes will override previously stored attributes. For example, if it is first called with a MAC address, but later, it is desired to add an IP address, it will then be required to call it with both the IP and MAC addresses to prevent overiding the MAC address.

Because this is an asynchronous call, it will always return 200, whether an association occurs or not. To confirm if an association was found based on the provided details, call ListAssociatedResource.

Examples:

Request syntax with placeholder values


resp = client.put_resource_attributes({
  progress_update_stream: "ProgressUpdateStream", # required
  migration_task_name: "MigrationTaskName", # required
  resource_attribute_list: [ # required
    {
      type: "IPV4_ADDRESS", # required, accepts IPV4_ADDRESS, IPV6_ADDRESS, MAC_ADDRESS, FQDN, VM_MANAGER_ID, VM_MANAGED_OBJECT_REFERENCE, VM_NAME, VM_PATH, BIOS_ID, MOTHERBOARD_SERIAL_NUMBER, LABEL

  • :migration_task_name (required, String)

    Unique identifier that references the migration task.

  • :resource_attribute_list (required, Array<Types::ResourceAttribute>)

    Information about the resource that is being migrated. This data will be used to map the task to a resource in the Application Discovery Service (ADS)\'s repository.

  • :dry_run (Boolean)

    Optional boolean flag to indicate whether any effect should take place. Used to test if the caller has permission to make the call.

Returns:

  • (Struct)

    Returns an empty response.

#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

Parameters:

  • waiter_name (Symbol)

    The name of the waiter. See #waiter_names for a full list of supported waiters.

  • params (Hash) (defaults to: {})

    Additional request parameters. See the #waiter_names for a list of supported waiters and what request they call. The called request determines the list of accepted parameters.

Yield Parameters:

Returns:

  • (Boolean)

    Returns true if the waiter was successful.

Raises:

  • (Errors::FailureStateError)

    Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.

  • (Errors::TooManyAttemptsError)

    Raised when the configured maximum number of attempts have been made, and the waiter is not yet successful.

  • (Errors::UnexpectedError)

    Raised when an error is encounted while polling for a resource that is not expected.

  • (Errors::NoSuchWaiterError)

    Raised when you request to wait for an unknown state.

#waiter_namesArray<Symbol>

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