i am new to ubuntu core, i have Ubuntu core 20 VM and installed Docker Snap.
I am creating a service which needs to pull latest image and run docker container.
if i write docker command without sudo, below script is failing.
how to fix this, i read many topics about adding user to docker group, i am not able to find docker group after installing docker snap.
Hi, unfortunately the docker snap is not currently usable without sudo on Ubuntu Core.
Based on ubuntu snap docker run as a normal user · GitHub it seems it is possible. It worked for me on Ubuntu 24.04.
Step 1: Create the ‘docker’ system group if it does not exist. This group is required by the Docker daemon for non-root access to its socket.
sudo addgroup --system docker
Step 2: Verify that the ‘docker’ group now exists.
grep docker /etc/group
You should see output like: docker:x:NNN: (where NNN is the GID)
Step 3: Add your user to the ‘docker’ group.
sudo adduser $USER docker
Step 4: Activate the new group membership for your current shell session. Alternatively, log out and log back in.
newgrp docker
Step 5: Disable and re-enable the docker snap. This ensures the snap’s environment picks up the changes in group membership.
sudo snap disable docker
sudo snap enable docker
