How to forward docker.sock

[elyrtan]

Hi,

i'm playing around with gitlab runner docker image and trying to have it talk with the docker host engine.
I run the container like so:

docker run -d --name gitlab-runner --restart always \
-v gitlab-runner-config:/etc/gitlab-runner \
-v /Users/myUser/.colima/default/docker.sock:/var/run/docker.sock \
gitlab/gitlab-runner:latest

However the runner looks unable to talk with the docker engine for now, ci jobs are failing with :

ERROR: Preparation failed: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running? (docker.go:754:0s)
Will be retried in 3s ...
ERROR: Failed to remove network for build
ERROR: Preparation failed: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running? (docker.go:[7](https://gitlab.com/blah/hello-world/-/jobs/4069024169#L7)54:0s)

Just to make sure, I've tried running portainer container which looks unable to talk with the docker host engine as well.

Is there something configurable colima side ?

My colima status:

INFO[0000] colima is running using QEMU
INFO[0000] arch: aarch64
INFO[0000] runtime: docker
INFO[0000] mountType: sshfs
INFO[0000] address: 192.168.106.2
INFO[0000] socket: unix:///Users/myUser/.colima/default/docker.sock

-v /Users/myUser/.colima/default/docker.sock:/var/run/docker.sock \

This is the location of the socket on the host. You need to forward the location inside the VM, so probably:

-v /var/run/docker.sock:/var/run/docker.sock
