UpdateContainerGroupDefinition

This API works with the following fleet types: Container

Updates properties in an existing container group definition. This operation doesn't replace the definition. Instead, it creates a new version of the definition and saves it separately. You can access all versions that you choose to retain.

The only property you can't update is the container group type.

Request options:

Update based on the latest version of the container group definition. Specify the container group definition name only, or use an ARN value without a version number. Provide updated values for the properties that you want to change only. All other values remain the same as the latest version.
Update based on a specific version of the container group definition. Specify the container group definition name and a source version number, or use an ARN value with a version number. Provide updated values for the properties that you want to change only. All other values remain the same as the source version.
Change a game server container definition. Provide a complete set of container definitions, including the updated definition.
Add or change a support container definition. Provide a complete set of container definitions, including the updated definition.
Remove a support container definition. Provide a complete set of container definitions, excluding the definition to remove. If the container group has only one support container definition, provide an empty set.
Remove the total vCPU limit from a game server container group so that its containers can use up to the instance's available vCPU. Set RemoveAttributes to TOTAL_VCPU_LIMIT. The game server container must have a Vcpu value, because a game server container group needs either a total vCPU limit or a game server Vcpu value.

Results:

If successful, this operation returns the complete properties of the new container group definition version.

If the container group definition version is used in an active fleet, the update automatically initiates a new fleet deployment of the new version. You can track a fleet's deployments using ListFleetDeployments.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

Note

In the following list, the required parameters are described first.

Name

A descriptive identifier for the container group definition. The name value must be unique in an AWS Region.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 512.

Pattern: ^[a-zA-Z0-9\-]+$|^arn:.*:containergroupdefinition\/[a-zA-Z0-9\-]+(:[0-9]+)?$

Required: Yes

GameServerContainerDefinition

An updated definition for the game server container in this group. Define a game server container only when the container group type is GAME_SERVER. You can pass in your container definitions as a JSON file.

Type: GameServerContainerDefinitionInput object

Required: No

OperatingSystem

The platform that all containers in the group use. Containers in a group must run on the same operating system.

Note

Amazon Linux 2 (AL2) will reach end of support on 6/30/2026. See more details in the Amazon Linux 2 FAQs. For game servers that are hosted on AL2 and use server SDK version 4.x for Amazon GameLift Servers, first update the game server build to server SDK 5.x, and then deploy to AL2023 instances. See Migrate to server SDK version 5.

Type: String

Valid Values: AMAZON_LINUX_2023

Required: No

RemoveAttributes

If set, this update removes the container group's total vCPU limit, and the group's containers can use up to the instance's available vCPU. You can't remove the total vCPU limit from a per-instance container group. A game server container group needs either a total vCPU limit or a Vcpu value for the game server container. You can't set TotalVcpuLimit in the same request.

Type: Array of strings

Array Members: Fixed number of 1 item.

Valid Values: TOTAL_VCPU_LIMIT

Required: No

SourceVersionNumber

The container group definition version to update. The new version starts with values from the source version, and then updates values included in this request.

Type: Integer

Valid Range: Minimum value of 1.

Required: No

SupportContainerDefinitions

One or more definitions for support containers in this group. You can define a support container in any type of container group. You can pass in your container definitions as a JSON file.

Type: Array of SupportContainerDefinitionInput objects

Array Members: Minimum number of 0 items. Maximum number of 10 items.

Required: No

TotalMemoryLimitMebibytes

The maximum amount of memory (in MiB) to allocate to the container group. All containers in the group share this memory. If you specify memory limits for an individual container, the total value must be greater than any individual container's memory limit.

Type: Integer

Valid Range: Minimum value of 4. Maximum value of 1024000.

Required: No

TotalVcpuLimit

The maximum amount of vCPU units to allocate to the container group (1 vCPU is equal to 1024 CPU units). All containers in the group share these resources. If you set vCPU reservations for individual containers, the total value must be equal to or greater than the sum of the Vcpu values for all containers in the group.

For a game server container group, Amazon GameLift Servers requires either a total vCPU limit or a Vcpu value for the game server container. If the container group has a total vCPU limit, Amazon GameLift Servers uses this value to calculate how many game server container groups fit on an instance. If the container group doesn't have a total vCPU limit, its containers can use up to the instance's available vCPU, and Amazon GameLift Servers uses the sum of the containers' Vcpu values to calculate how many game server container groups fit on an instance. To remove the total vCPU limit, omit this parameter and set RemoveAttributes to TOTAL_VCPU_LIMIT.

Type: Double

Valid Range: Minimum value of 0.125. Maximum value of 10.

Required: No

VersionDescription

A description for this update to the container group definition.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1024.

Required: No

Examples

Update a game server container group definition for a new support container

This example adds a new support container definition to a game server container group that previously had one game server container defined. The request has these characteristics:

A source version isn't provided, and the container group Name parameter is an ARN without a version number. As a result, this update will use the latest version as the source.
The request changes the total memory limit for the container group.
The new support container definition supplies the minimum required parameters.

As shown, an update request includes only the properties that you want to change or add.

HTTP requests are authenticated using an AWS Signature Version 4 signature in the Authorization header field.
