Setup standalone Gitaly

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 VM with Omnibus GitLab

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.

Configure Omnibus GitLab

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 based on Running Gitaly on its own server docs.

NOTE: The values below should be replaced

# Avoid running unnecessary services on the Gitaly server
postgresql['enable'] = false
redis['enable'] = false
nginx['enable'] = false
prometheus['enable'] = false
unicorn['enable'] = false
sidekiq['enable'] = false
gitlab_workhorse['enable'] = false

# Prevent database connections during 'gitlab-ctl reconfigure'
gitlab_rails['rake_cache_clear'] = false
gitlab_rails['auto_migrate'] = false

# Configure the gitlab-shell API callback URL. Without this, `git push` will
# fail. This can be your 'front door' GitLab URL or an internal load
# balancer.
gitlab_rails['internal_api_url'] = 'GITLAB_URL'
gitlab_shell['secret_token'] = 'SHELL_TOKEN'

# Make Gitaly accept connections on all network interfaces. You must use
# firewalls to restrict access to this address/port.
gitaly['listen_addr'] = "0.0.0.0:8075"
gitaly['auth_token'] = 'AUTH_TOKEN'

gitaly['storage'] = [
  { 'name' => 'default', 'path' => '/mnt/gitlab/default/repositories' },
  { 'name' => 'storage1', 'path' => '/mnt/gitlab/storage1/repositories' },
]

# To use TLS for Gitaly you need to add
gitaly['tls_listen_addr'] = "0.0.0.0:9999"
gitaly['certificate_path'] = "path/to/cert.pem"
gitaly['key_path'] = "path/to/key.pem"

After creating gitlab.rb, 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: gitaly: (pid 30562) 77637s; run: log: (pid 30561) 77637s run: logrotate: (pid 4856) 1859s; run: log: (pid 31262) 77460s
