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.

Type: String

Valid Values: READY | COPYING | FAILED

Required: No

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 AWS account.

Array Members: Minimum number of 1 item. Maximum number of 10 items.

Required: No

TotalMemoryLimitMebibytes
