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.

Docker-in-Docker in Gitlab Runners | by Tony Wooster | Medium
January 31, 2018 - To get started, let’s create a network for it to exist in: ... # docker run -d \ --name gitlab-dind \ --privileged \ --restart always \ --network gitlab-runner-net \ -v /var/lib/docker \ docker:17.06.0-ce-dind \ --storage-driver=overlay2
GitLab 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.

August 31, 2023A 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?

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?

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.

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

Each job gets its own isolated Docker daemon, so concurrent jobs do not conflict. Use this approach when your runner supports privileged mode. For setup instructions, see Use Docker-in-Docker.

Because of the Docker-in-Docker setup and therefore the separate docker daemon, GitLab jobs are not able to access containers, images, or volumes outside the job. Create Gitlab runner config and register runner in GitLab project or group:

Optional. Run other services, like MySQL, in containers. Do this by specifying services in your .gitlab-ci.yml file. To use GitLab Runner with Docker you need to register a runner that uses the Docker executor.

Docker executor | GitLab Docs
The Docker executor uses Docker Engine to run each job in a separate and isolated container. To connect to Docker Engine, the executor uses: The image and services you define in .gitlab-ci.yml. The configurations you define in config.toml. You can’t register a runner and its Docker executor without defining a default image in config.toml.

We are setting network_mode to host for the GitLab runner container which will put the GitLab runner container on the host machine’s network so GitLab server can communicate with it through localhost instead of using its container name (container ID can change everytime we recreate containers).
