Openshift (oc) login to registry keeps on failing - how to start the Docker daemon?

Question

After starting a command prompt, I normally start with login in to openshift with this command:

$ oc login https://api.starter-us-west-1.openshift.com --token=

Works fine. Up till now I then connected to the docker registry of Openshift with the command:

$ docker login -u myOpenShiftName -p registry.starter-us-west-1.openshift.com (or :443)

Now I get this error (partly translated):

Warning: failed to get default registry endpoint from daemon (error during connect: Get http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.37/info: open //./pipe/docker_engine: The system cannot find the specified file. In the default daemon configuration on Windows, the docker client must be run elevated to connect. This error may also indicate that the docker daemon is not running.). Using system default: https://index.docker.io/v1/

Do I need a local docker running?

UPDATE/ANSWER: yes. On windows10 home start e.g. DockerQuickstartTerminal.

At another computer I had a similar error on Windows 10 pro with Docker. The service was started, but after I had started "Docker for Windows" the error disappeared.

My environment is Win10 home, virtual box + extension + docker toolbox.

Answer 1

The docker command cannot work without its local Docker daemon process running.

If you want to be able to work with OCI/Docker images and not need docker and the daemon, for some things you can use a tool like Skopeo.

There are also tools for building OCI container images which aren't dependent on docker.
