Docker no basic auth credentials after succesfull login

Question

I've moved to linux (pop_os 21.04) on my desktop and I'm having some issues with docker. When I'm trying to run docker-compose to pull an image from a private registry I'm getting:

ERROR: Head "https://my.registry/my-image/manifests/latest": no basic auth credentials

Of course before running this command I've ran: docker login https://my.registry.com -u user -p pass which returns

WARNING! Your password will be stored unencrypted in /home/user/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store

Login Succeeded

And my config.json in my .docker folder show my credentials

 {
    "auths": {
        "my.registry.com": {
            "auth": "XXXXX"
        }
    }
}

To install docker I've followed instructions on their page https://docs.docker.com/engine/install/ubuntu/

And my version is: Docker version 20.10.8, build 3967b7d

The same command ran on a macos system with Docker version 20.10.8 runs without any issues so I my password and all the urls are correct for sure.

Thanks for any help!

Answer 1

Ran into the same issue and my problem was that I logged in without sudo and afterwards tried to run containers with sudo privileges.

So the solution for me was to run sudo login ... and afterwards sudo docker compose up -d.
