When a job is based on a Docker image [1], or is using a Docker
service, it requires a runner with Docker installed.

Gitlab shared runners provide the 'docker' tag when they have it
installed.

Are Gitlab shared runners are limited resources, we'd like to
add more runners to QEMU repositories hosted on Gitlab. If a
runner doesn't provide Docker, our jobs requiring it will fail.

Use the standard 'docker' tag to mark the jobs requiring Docker
on the runner.

If someone is interested in testing or filling the documentation
gap, what I ran is:

$ sudo usermod -aG docker,kvm gitlab-runner
$ sudo gitlab-runner --log-format text --log-level debug \
    register \
 --non-interactive \
 --url https://gitlab.com --registration-token MYTOKEN --description myrunner \
 --tag-list 'docker,linux,x86_64,kvm' --run-untagged --limit 2 \
 --executor docker --docker-image docker:dind --docker-cpus 4 \
 --docker-volumes /var/run/docker.sock:/var/run/docker.sock \
 --docker-dns 8.8.8.8

--docker-volumes is for docker:dind else it was not working
This comes from this 3 year old thread:
https://gitlab.com/gitlab-org/gitlab-runner/-/issues/1986

We can not use the 'docker:dind' tag for a runner having docker:dind
and /var/run/docker.sock volume because this is not a tag used by
the shared runners, so we can't use them anymore.

If you add it to the templates ... won't this disable most of the jobs on 
the dedicated runners that don't have docker? Wouldn't it be better to add 
the tag only to the jobs that run "make check-tcg" ?

(I don't know if the docker dependency is presently expressed with the
exact granularity that we need, but I'm willing to ACK the edk2 part, on
principle. We should be explicit about dependencies.)

Thanks

But this is the point, if a runner doesn't have Docker, it can not
run the job...
