Docker Engine Authentication

As explained in the Marathon docs using private registries requires that credentials are provided using an archive. This archive is generated during cluster provisioning on all Mesos agents based on credentials in credentials/secret.yml.

Requires the credentials for all Docker registries to log into to be defined via the docker_credentials configuration variable.

Note: this will run docker login on all hosts.

Configuration

Defaults are set in defaults/main.yml.

• docker_credentials:

  Credentials for authenticating access to private Docker registries.

  For each registry, specify the server, username, password and email. E.g.:

  docker_credentials:
    - server: docker.example.com
      username: pull-user
      password: secret
      email: pull-user@example.com
    - server: quay.io
      username: pull-user2
      password: secret
      email: pull-user2@example.com
  

  Default:

  docker_credentials: []
