Class: Aws::ResourceGroups::Client

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

Overview

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

resourcegroups = Aws::ResourceGroups::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::ResourceGroups::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.

Options Hash (options):

  • :name (required, String) —

A resource group name must be unique within each AWS Region in your AWS account.

  • :description (String) —

    The description of the resource group. Descriptions can consist of letters, numbers, hyphens, underscores, periods, and spaces.

  • :resource_query (Types::ResourceQuery) —

    The resource query that determines which AWS resources are members of this group.

    You can specify either a ResourceQuery or a Configuration, but not both.

  • :tags (Hash<String,String>) —

    The tags to add to the group. A tag is key-value pair string.

  • :configuration (Array<Types::GroupConfigurationItem>) —

    A configuration associates the resource group with an AWS service and specifies how the service can interact with the resources in the group. A configuration is an array of GroupConfigurationItem elements.

    You can specify either a Configuration or a ResourceQuery in a group, but not both.

    {
      name: "resource-type", # required, accepts resource-type

Options Hash (options):

  • :group_name (String) —

    Don\'t use this parameter. Use Group instead.

  • :group (String) —

    The name or the ARN of the resource group

  • :filters (Array<Types::ResourceFilter>) —

    Filters, formatted as ResourceFilter objects, that you want to apply to a ListGroupResources operation. Filters the results to include only those of the specified resource types.

    • resource-type - Filter resources by their type. Specify up to five resource types in the format AWS::ServiceCode::ResourceType. For example, AWS::EC2::Instance, or AWS::S3::Bucket.

    ^

    When you specify a resource-type filter for ListGroupResources, AWS Resource Groups validates your filter resource types against the types that are defined in the query associated with the group. For example, if a group contains only S3 buckets because its query specifies only that resource type, but your resource-type filter includes EC2 instances, AWS Resource Groups does not filter for EC2 instances. In this case, a ListGroupResources request returns a BadRequestException error with a message similar to the following:

    The resource types specified as filters in the request are not valid.

    The error includes a list of resource types that failed the validation because they are not part of the query associated with the group. This validation doesn\'t occur when the group query specifies AWS::AllSupported, because a group based on such a query can contain any of the allowed resource types for the query type (tag-based or AWS CloudFormation stack-based queries).

  • :max_results (Integer) —

    The total number of results that you want included on each page of the response. If you do not include this parameter, it defaults to a value that is specific to the operation. If additional items exist beyond the maximum you specify, the NextToken response element is present and has a value (is not null). Include that value as the NextToken request parameter in the next call to the operation to get the next part of the results. Note that the service might return fewer results than the maximum even when there are more results available. You should check NextToken after every operation to ensure that you receive all of the results.

  • :next_token (String) —

    The parameter for receiving additional results if you receive a NextToken response in a previous request. A NextToken response indicates that more output is available. Set this parameter to the value provided by a previous call\'s NextToken response to indicate where the output should continue from.

Returns:

#list_groups(options = {}) ⇒ Types::ListGroupsOutput

#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) —
