gcloud beta auth configure-docker

NAME
gcloud beta auth configure-docker - register gcloud as a Docker credential helper
SYNOPSIS
gcloud beta auth configure-docker [REGISTRIES] [GCLOUD_WIDE_FLAG …]
DESCRIPTION
(BETA) gcloud beta auth configure-docker adds the Docker credHelper entry to Docker's configuration file, or creates the file if it doesn't exist. This will register gcloud as the credential helper for all Google-supported Docker registries. If the Docker configuration already contains a credHelper entry, it will be overwritten.

Note: docker and gcloud need to be on the same system PATH to work correctly.

Note: This command will not work for docker installed via Snap, as the docker snap package does not currently provide an interface for credential helpers.

For more details on Docker registries, see https://docs.docker.com/registry/.

For more details on how to authenticate to Google Container Registry using this command, see https://cloud.google.com/container-registry/docs/advanced-authentication#gcloud-helper.

For more details on Google Container Registry's standalone credential helpers, see https://github.com/GoogleCloudPlatform/docker-credential-gcr.

For more details on Docker credential helpers, see https://docs.docker.com/engine/reference/commandline/login/#credential-helpers.
