error: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

[aabdou]

I set up a user X, added it to the docker group and I can run docker info and docker run successfully when I'm logged in as user X. In my deploy.yml (in my rails app), I have ssh user set to X. When I run kamal setup, I get the error below:
error: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

I'm on Rails 8 beta and my server is running Ubuntu 20.04

Did you followed these step to manually bootstrap your server?
https://kamal-deploy.org/docs/configuration/ssh/

I'd suggest to try to see if following command works:

kamal server exec "whoami" # should show your user X
kamal server exec "docker run hello-world" # should run if docker daemon running and accessible for user X

Thank you. Turned out it was failing locally as it tried to build the container. By default kamal uses docker-container and on Mac, docker runs in a VM and on my machine docker-container does not work. I changed Kamal’s config to use docker instead and it works now :)
