The instructions here make use of the Omnibus GitLab package for Ubuntu. This package provides versions of the services that are guaranteed to be compatible with the charts’ services.
Create a VM on your provider of choice, or locally. This was tested with VirtualBox, KVM, and Bhyve. Ensure that the instance is reachable from the cluster.
Install Ubuntu Server onto the VM that you have created. Ensure that
openssh-server is installed, and that all packages are up to date.
Configure networking and a hostname. Make note of the hostname/IP, and ensure it is both resolvable and reachable from your Kubernetes cluster.
Be sure firewall policies are in place to allow traffic.
Follow the installation instructions for Omnibus GitLab. When you perform the package installation, do not provide the
EXTERNAL_URL= value. We do not want automatic configuration to occur, as we’ll provide a very specific configuration in the next step.
Create a minimal
gitlab.rb file to be placed at
/etc/gitlab/gitlab.rb. Be very explicit about what is enabled on this node, use the contents below.
Note: This example is not intended to provide Redis HA.
REDIS_PASSWORDshould be replaced with the value in the
# Listen on all addresses redis['bind'] = '0.0.0.0' # Set the defaul port, must be set. redis['port'] = 6379 # Set password, as in the secret `gitlab-redis` populated in Kubernetes redis['password'] = 'REDIS_PASSWORD' ## Disable everything else gitlab_rails['enable'] = false sidekiq['enable'] = false unicorn['enable'] = false registry['enable'] = false gitaly['enable'] = false gitlab_workhorse['enable'] = false nginx['enable'] = false prometheus_monitoring['enable'] = false postgresql['enable'] = false
gitlab.rb, we’ll reconfigure the package with
gitlab-ctl reconfigure. Once the task has completed, check the running processes with
gitlab-ctl status. The output should appear as such:
# gitlab-ctl status run: logrotate: (pid 4856) 1859s; run: log: (pid 31262) 77460s run: redis: (pid 30562) 77637s; run: log: (pid 30561) 77637s
