Starting docker container results in docker-credential-secretservice: The connection is closed

Question

I'm trying to start the docker container from this tutorial (Quick-Start Installation and Tutorial): https://zuul-ci.org/docs/zuul/admin/quick-start.html#start-zuul-containers

docker.errors.DockerException: Credentials store error: StoreError('Credentials store docker-credential-secretservice exited with "The connection is closed".',)

What can possibly be causing this error? What is the solution for it?

I tried to reinstall docker-compose & docker.io, but no success.

Thank you.

Answer 1

I can't call it a solution really, but it helped me get rid of this problem and start the containers.

The steps are:

1. In ~/.docker/config.json remove the line "credsStore":"secretservice"
2. cd zuul/doc/source/admin/examples
3. sudo -E docker-compose up

The containers should start now.

Thanks for sharing Ivan. I had to do a docker login prior to your solution though, as I did not have a config.json file in my ~/.docker/.docker directory.
