# From https://docs.gitlab.com/ee/user/gitlab_com/#shared-runners:
#
# ...
#
# All your CI/CD jobs run on n1-standard-1 instances with 3.75GB of RAM, CoreOS
# and the latest Docker Engine installed. Instances provide 1 vCPU and 25GB of
# HDD disk space. The default region of the VMs is US East1. Each instance is
# used only for one job, this ensures any sensitive data left on the system can’t
# be accessed by other people their CI jobs.
#
# The gitlab-shared-runners-manager-X.gitlab.com fleet of runners are dedicated
# for GitLab projects as well as community forks of them. They use a slightly
# larger machine type (n1-standard-2) and have a bigger SSD disk size. They don’t
# run untagged jobs and unlike the general fleet of shared runners, the instances
# are re-used up to 40 times.
#
# ...
#
# The n1-standard-1 runners seem to be tagged with 'docker' together with 'gce'.
#
# The more powerful n1-standard-2 runners seem to be tagged with
# 'gitlab-org-docker' or some with just 'gitlab-org'.
#
#
# Our current private runner 'docker', 'samba-ci-private', 'shared' and
# 'ubuntu2204'. It runs with an ubuntu2204 kernel (5.15) and provides an
# ext4 filesystem and similar RAM as the n1-standard-2 runners.
#
.shared_runner_build:
# We use n1-standard-1 shared runners by default.
#
# There are currently 5 shared runners with 'docker' and 'gce',
# while there are only 2 provising 'docker' together with 'shared'.
#
# We used to fallback to our private runner if the docker+shared runners
# were busy, but now that we use the 5 docker+gce runners, we try to only
# use shared runners without a fallback to our private runner!
# Lets see how that will work out.
