perInstanceContainerGroupDefinitionName

The name or ARN value of a new per-instance container group definition to deploy on the fleet. If you're updating the fleet to a specific version of a container group definition, use the ARN value and include the version number. If you're updating the fleet to the latest version of a container group definition, you can use the name value.

Update a container group definition by calling UpdateContainerGroupDefinition. This operation creates a ContainerGroupDefinition resource with an incremented version.

To remove a fleet's per-instance container group definition, leave this parameter empty and use the parameter RemoveAttributes.
