Configure runner to run multiple jobs at the same time

Question

When having one gitlab runner serving multiple projects, it can only run one CI pipeline while the other project pipelines have to queue.

Is it possible to make a gitlab runner run pipelines from all projects in parallel?

I don't seem to find anywhere a configuration explanation for this.

Answer 1

I believe the configuration options you are looking for is concurrent and limit, which you'd change in the GitLab Runners config.toml file.

From the documentation:

• concurrent: limits how many jobs globally can be run concurrently. The most upper limit of jobs using all defined runners. 0 does not mean unlimited

• limit: limit how many jobs can be handled concurrently by this token.

The location for the config.toml file:

• /etc/gitlab-runner/config.toml on *nix systems when GitLab Runner is executed as root (this is also path for service configuration)
• ~/.gitlab-runner/config.toml on *nix systems when GitLab Runner is executed as non-root
• ./config.toml on other systems

Useful issue as well.
