Azure – Permission denied while trying to connect to the Docker daemon socket

here is the error message that you got :

permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/images/load?quiet=0": dial unix /var/run/docker.sock: connect: permission denied

The error message you’re seeing indicates that your current user does not have the necessary permissions to connect to the Docker daemon.

1. Add Your User to the Docker Group

1. Add your user to the Docker group:

   sudo usermod -aG docker $USER

2. Log out and log back in to apply the group changes, or run the following command to refresh your group membership

   newgrp docker

3. Verify you can run Docker commands without sudo:

   docker ps

Now check if this fix your problem, it should.

if not then try next topic.

2. Check Docker Daemon Status

Make sure the Docker daemon is running. You can start it with the following command:

sudo systemctl start docker

To check its status:

sudo systemctl status docker

!!! At this point it’s should work now !!!

Below is a further troubleshooting.

Reinstall Docker

If you still encounter issues, ensure Docker is installed correctly. You can reinstall Docker if necessary:

sudo apt-get remove docker docker-engine docker.io containerd runc
sudo apt-get install docker.io

Check File Permissions

Ensure that the permissions of the /var/run/docker.sock socket file are correct:

ls -l /var/run/docker.sock

You should see something like this:

srw-rw---- 1 root docker 0 date /var/run/docker.sock

If the group is not docker, you can change it:

sudo chown root:docker /var/run/docker.sock
sudo chmod 660 /var/run/docker.sock

Adding your user to the docker group should stop your issue.
