docker-credential-gcr

--default-to-gcr-access-token has been added as a config value. By default, the credential helper will still return an error when an unknown credential is requested, but when --default-to-gcr-access-token is enabled the credential helper will attempt to return GCR's access token instead. This allows for the credential helper to be used for non-default GCR registries.

Some users were having issues using configure-docker, which is solved in this bugfix.

Credential helper support has been cherry picked into v1.13.0-rc4. docker-credential-gcr has been updated to reflect that.

Docker client v1.14 introduces registry-specific credential helpers. docker-credential-gcr will now preferentially act as a credential helper on Docker client versions 1.14+ and as a general credential store on 1.11 - 1.13.

You must now use "gcloud" rather than "gcloud_sdk" to reference gcloud as a token source.

Added 2 new user controls for docker-credential-gcr:

• docker-credential-gcr config: Configure where (and in which order) the credential helper searches for GCR credentials.
• docker-credential-gcr clear: Remove ALL stored credentials. Handier than specifically gcr-logouting followed by several erases

This release contains support for beta.gcr.io, as well as a fix where 'docker build' was not pulling GCR's credentials.
