How many resources does GitLab Runner need in Docker?

Run GitLab Runner in a container | GitLab Docs
Run the gitlab-runner Docker image by using the docker run -d [options] <image-uri> <runner-command> command. When you run gitlab-runner in a Docker container, ensure the configuration is not lost when you restart the container. Mount a permanent volume to store the configuration.

A few questions about GitLab Runner and Docker
Hello, In the GitLab Runner documentation it was written that it should be installed on a separate server from the GitLab server. 1- Can I install it alongside the Docker server or do I have to dedicate a separate server to it? 2- Is it better to install it as a container or an application?

April 9, 2024GitLab Runner in Docker
I’d suggest setting up your runners using the docker executor - https://docs.gitlab.com/runner/executors/docker.html This allows your runner to start up fresh containers for jobs with the image you specify, meaning jobs aren’t running on the host and can have whatever you need. You can then also use a single runner with parallelism instead of multiple runners. Downside is that if you need to install extras they will need to install as part of the CI on every job.

r/gitlab on Reddit: GitLab Runner in Docker
August 31, 2023 -
Hi all,
We recently moved to GitLab, and I am tasked with setting up the testing stuff for our pipeline.
We had gitlab runners recently installed on our server, but I am running into some problems. I’m new to all this, so while reading documentation has been helpful, I’m still unsure on a lot of things.
The Gitlab-Runner is installed and registered on 3 separate docker containers in the server (so 3 runners total)
The docker containers use the official docker alpine gitlab runner image
The Gitlab-Runner is in shell executor mode
When I run my script through gitlab-ci, I am getting command not found for sudo, apt, node, npm, docker, etc.
From what i can tell, that’s because the runner is running the CI script directly in the docker container from the official images, which do not have any of these installed.
So even if I switch from shell executor to docker executor, this would not work since the official runner image doesn’t have docker installed correct?
Is the correct path here to start docker containers with gitlab runners registered in it, but the docker container itself needs to be docker in docker? Is the official gitlab runner alpine image able to run in docker in docker?

Can you pass the docker API socket to the runner containers so they can run new containers with the job using the Docker executer?

There is --privileged parameter
https://docs.docker.com/engine/reference/run/#/runtime-privilege-and-linux-capabilities
Which should give capability to run docker inside docker. So theoretically it possible, but you probably run into other problems.

You need to mount docker.sock , set --privileged
docker run -d -v /var/run/docker.sock:/var/run/docker.sock --name gitlab-runner --privileged --restart always -v d:/docker/data/gitlab-runner:/etc/gitlab-runner gitlab/gitlab-runner:latest
And set config privileged .
[[runners]]
name = "docker2"
url = "https://gitlab.com/"
token = "xxxxx"
executor = "docker"
[runners.docker]
image = "alpine:latest"
privileged = true
disable_entrypoint_overwrite = false
oom_kill_disable = false
disable_cache = false

November 7, 2019 - The first thing to do then is the need to mount a config volume in the ‘gitlab-runner’ container to be used for configs in your terminal. That is done by running this command in your terminal; (insert a container name you desire after the name tag). docker run -d --name [container-name] --restart always --privileged -v $(pwd):/etc/gitlab-runner -v /var/run/docker.sock:/var/run/docker.sock gitlab/gitlab-runner:latest
