If you use Docker and get it running while using Docker Desktop, you might run into this error:
docker.errors.DockerException: Error while fetching server API version: ('Connection aborted.', FileNotFoundError(2, 'No such file or directory'))
That’s because Docker Desktop is well, not running. What if you could run Docker without needing Docker Desktop?
Check if the service is running
sudo systemctl status docker
Verify if the Docker socket exists by running:
ls -l /var/run/docker.sock
output: srw-rw---- 1 root docker 0 ... /var/run/docker.sock
If not, start the Docker service or reinstall Docker. If docker --version is not around, do same.
On ubuntu/linux mint verify if you have the correct permission
sudo usermod -aG docker $USER
You can also try restarting the service
sudo systemctl restart docker
If you get when running docker version
Client: Docker Engine - Community
Version: 27.3.1
API version: 1.47
Go version: go1.22.7
Git commit: ce12230
Built: Fri Sep 20 11:41:11 2024
OS/Arch: linux/amd64
Context: desktop-linux
Cannot connect to the Docker daemon at unix:///home/appinv/.docker/desktop/docker.sock. Is the docker daemon running?
Then, temporarily add this env var
export DOCKER_HOST=unix:///var/run/docker.sock
Also do the above if getting
Dec 03 13:44:47 appinv-machine dockerd[22962]: time="2024-12-03T13:44:47.469983115+04:00" level=info msg="API listen on /run/docker.sock"
Add permanently if fixed.
If you get an error like the below which occurs as a result of authing through Docker Desktop
ERROR: failed to solve: ...: failed to resolve source metadata for docker.io/...: error getting credentials - err: exec: "docker-credential-desktop": executable file not found in $PATH, out: `
ERROR: Service '...' failed to build : Build failed
Edit this file
nano ~/.docker/config.json
Replace "credsStore": "desktop" with "credsStore": ""
Else login throught docker hub.
Hope it helps1
