list-container-group-definitions

Description

Retrieves container group definitions for the Amazon Web Services account and Amazon Web Services Region. Use the pagination parameters to retrieve results in a set of sequential pages.

This operation returns only the latest version of each definition. To retrieve all versions of a container group definition, use ListContainerGroupDefinitionVersions .

Request options:
  • Retrieve the most recent versions of all container group definitions.
  • Retrieve the most recent versions of all container group definitions, filtered by type. Specify the container group type to filter on.
Results:

If successful, this operation returns the complete properties of a set of container group definition versions that match the request.

Note

This operation returns the list of container group definitions in no particular order.

See also: AWS API Documentation

list-container-group-definitions is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: ContainerGroupDefinitions

Options

--container-group-type (string)

The type of container group to retrieve. Container group type determines how Amazon GameLift deploys the container group on each fleet instance.

Possible values:

  • GAME_SERVER
  • PER_INSTANCE

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Note

Amazon Linux 2 (AL2) will reach end of support on 6/30/2025. See more details in the Amazon Linux 2 FAQs . For game servers that are hosted on AL2 and use Amazon GameLift server SDK 4.x, first update the game server build to server SDK 5.x, and then deploy to AL2023 instances. See Migrate to Amazon GameLift server SDK version 5.

Name -> (string)

A descriptive identifier for the container group definition. The name value is unique in an Amazon Web Services Region.

TotalMemoryLimitMebibytes -> (integer)

The amount of memory (in MiB) on a fleet instance to allocate for the container group. All containers in the group share these resources.

You can set a limit for each container definition in the group. If individual containers have limits, this total value must be greater than any individual container's memory limit.

TotalVcpuLimit -> (double)

The amount of vCPU units on a fleet instance to allocate for the container group (1 vCPU is equal to 1024 CPU units). All containers in the group share these resources. You can set a limit for each container definition in the group. If individual containers have limits, this total value must be equal to or greater than the sum of the limits for each container in the group.

GameServerContainerDefinition -> (structure)

The definition for the game server container in this group. This property is used only when the container group type is GAME_SERVER . This container definition specifies a container image with the game server build.

ContainerName -> (string)

The container definition identifier. Container names are unique within a container group definition.

DependsOn -> (list)

Indicates that the container relies on the status of other containers in the same container group during startup and shutdown sequences. A container might have dependencies on multiple containers.

(structure)

A container's dependency on another container in the same container group. The dependency impacts how the dependent container is able to start or shut down based the status of the other container.

For example, ContainerA is configured with the following dependency: a START dependency on ContainerB . This means that ContainerA can't start until ContainerB has started. It also means that ContainerA must shut down before ContainerB .

  • FAILED -- Amazon GameLift failed to create a valid container group definition resource. For more details on the cause of the failure, see StatusReason . A container group definition resource in failed status will be deleted within a few minutes.

StatusReason -> (string)

Additional information about a container group definition that's in FAILED status. Possible reasons include:

  • An internal issue prevented Amazon GameLift from creating the container group definition resource. Delete the failed resource and call CreateContainerGroupDefinition again.
  • An access-denied message means that you don't have permissions to access the container image on ECR. See IAM permission examples for help setting up required IAM permissions for Amazon GameLift.
