Using google cloud registry with docker while offline - docker

Question

I'm using Google Cloud Registry, associating with Docker using gcloud auth configure-docker.
https://cloud.google.com/sdk/gcloud/reference/auth/configure-docker
However, when my computer is offline and I run docker-compose up I get an error where it tries to communicate/authenticate with Google.
how can I use docker offline now that I've started using GCR?
$ docker-compose up --build --force-recreate -d
Building solr
ERROR: (gcloud.auth.docker-helper) There was a problem refreshing your current auth tokens: Unable to find the server at www.googleapis.com
Please run:
$ gcloud auth login
to obtain new credentials, or if you have already logged in with a
different account:
$ gcloud config set account ACCOUNT
to select an already authenticated account to use.

Answer 1

Docker-compose will read your YAML file to configure your application’s services , so if in your YAML you are using a Docker image or a personalized images and you don't have them on local, docker will try download them from the principal registry in your configuration, in this case Google Cloud Registry and if your are offline you will get an error.
