Applies a policy to a container image. We recommend that you call the RAM API CreateResourceShare (https://docs.aws.amazon.com//ram/latest/APIReference/API_CreateResourceShare.html) to share resources. If you call the Image Builder API <code>PutContainerImagePolicy</code>, you must also call the RAM API PromoteResourceShareCreatedFromPolicy (https://docs.aws.amazon.com//ram/latest/APIReference/API_PromoteResourceShareCreatedFromPolicy.html) in order for the resource to be visible to all principals with whom the resource is shared.
