    • operatingSystem

      public final ContainerOperatingSystem operatingSystem()

      The platform required for all containers in the container group definition.

      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.

      If the service returns an enum value that is not available in the current SDK version, operatingSystem will return ContainerOperatingSystem.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from operatingSystemAsString().

    • totalMemoryLimit

      public final Integer totalMemoryLimit()

      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 additional limits for each ContainerDefinition in the group. If individual containers have limits, this value must meet the following requirements:

      • Equal to or greater than the sum of all container-specific soft memory limits in the group.

      • Equal to or greater than any container-specific hard limits in the group.

      For more details on memory allocation, see the Container fleet design guide.

      Returns:
      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 additional limits for each ContainerDefinition in the group. If individual containers have limits, this value must meet the following requirements:

      • Equal to or greater than the sum of all container-specific soft memory limits in the group.

      For more details on memory allocation, see the Container fleet design guide.

    • totalCpuLimit

      public final Integer totalCpuLimit()

      The amount of CPU units on a fleet instance to allocate for the container group. All containers in the group share these resources. This property is an integer value in CPU units (1 vCPU is equal to 1024 CPU units).

      You can set additional limits for each ContainerDefinition in the group. If individual containers have limits, this value must be equal to or greater than the sum of all container-specific CPU limits in the group.

      For more details on memory allocation, see the Container fleet design guide.

    • hasContainerDefinitions

      public final boolean hasContainerDefinitions()
      For responses, this returns true if the service returned a value for the ContainerDefinitions property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • containerDefinitions

      public final List<ContainerDefinition> containerDefinitions()

      The set of container definitions that are included in the container group.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasContainerDefinitions() method.

      Returns:
      The set of container definitions that are included in the container group.

    • status

      public final ContainerGroupDefinitionStatus status()

      Current status of the container group definition resource. Values include:

      • COPYING -- Amazon GameLift is in the process of making copies of all container images that are defined in the group. While in this state, the resource can't be used to create a container fleet.

      • READY -- Amazon GameLift has copied the registry images for all containers that are defined in the group. You can use a container group definition in this status to create a container fleet.

      • 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.

      If the service returns an enum value that is not available in the current SDK version, status will return ContainerGroupDefinitionStatus.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from statusAsString().

    • statusReason

      public final String statusReason()

      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 CreateContainerGroupDefinitionagain.

      • 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.

      • The ImageUri value for at least one of the containers in the container group definition was invalid or not found in the current Amazon Web Services account.

      • At least one of the container images referenced in the container group definition exceeds the allowed size. For size limits, see Amazon GameLift endpoints and quotas.

      • At least one of the container images referenced in the container group definition uses a different operating system than the one defined for the container group.
