GNOME GitLab has AWS runners, but they are used only when pushing code into a GNOME upstream repository, not when you push into your personal fork. For personal forks there is only one (AFAIK) shared runner and you could be waiting for hours before it picks your job.
But did you know you can register your own PC, or a spare laptop collecting dust in a drawer, to get instant continuous integration (CI) going? It's really easy to setup!
apt install docker.io
Follow the instructions here:
https://gitlab.com/gitlab-org/gitlab-runner/blob/master/docs/install/linux-repository.md#installing-the-runner
(Note: The Ubuntu 18.04 package doesn't seem to work.)
sudo gitlab-runner install
sudo gitlab-runner start
Go to your gitlab project page, settings -> CI/CD -> expand "runners"
sudo gitlab-runner register --non-interactive --url https://gitlab.gnome.org --executor docker --docker-image fedora:27 --registration-token ****
You can repeat step 5 with the registration token of all your personal forks in the same GitLab instance. To make this easier, here's a snippet I wrote in my ~/.bashrc to register my "builder.local" machine on a new project. Use it as gitlab-register <token>.
function gitlab-register {
host=$1
token=$2
case "$host" in
gnome)
host=https://gitlab.gnome.org
;;
fdo)
host=https://gitlab.freedesktop.org
;;
collabora)
host=https://gitlab.collabora.com
;;
*)
host=https://gitlab.gnome.org
token=$1
esac
cmd="sudo gitlab-runner register --non-interactive --url $host --executor docker --docker-image fedora:27 --registration-token $token"
#$cmd
ssh builder.local -t "$cmd"
}
Not only will you now get faster CI, but you'll also reduce the queue on the shared runner for others!
