Docker wrong credentials

Resolving Docker Error

I have gotten an issue while attemting to build a Docker image with the following command:

docker build -t izfaha/express:v1 .

And I encountered this error:

Cannot connect to the Docker daemon at unix:///home/ray/.docker/desktop/docker.sock. Is the docker daemon running?

How do I tackle?

Root cause is:

First, Docker CLI was configured to use Docker Desktop, even though I was running native Docker in linux.

Second, the configuration file at ~/.docker/config.json contain:

{
  "auths": {},
  "credsStore": "desktop",
  "currentContext": "desktop-linux"
}

This caused Docker to:

• Attempt to connect to a nonexistent socket: /home/ray/.docker/desktop/docker.sock

• Call missing credentials helper: docker-credential-desktop

Solution

Ensure Docker Daemon is Running

sudo systemctl start docker
sudo systemctl enable docker

Switch Context to the Default Linux One

docker context use default
docker context ls               # to verify docker context set to default

Remove Faulty Docker Desktop Configuration

rm -rf ~/.docker
