Docker Registry to use for this deployment. This configuration is only applicable to 1st Gen functions, 2nd Gen functions can only use Artifact Registry. Deprecated: As of March 2025, CONTAINER_REGISTRY option is no longer available in response to Container Registry's deprecation: https://cloud.google.com/artifact-registry/docs/transition/transition-from-gcr Please use Artifact Registry instead, which is the default choice.

If unspecified, it defaults to ARTIFACT_REGISTRY. If docker_repository field is specified, this field should either be left unspecified or set to ARTIFACT_REGISTRY.
