Kubernetes Administration

Notes on deploying GitLab using their Helm chart.

Setup

To use your own PVs and PVCs,

Create your own PVs and PVCs for gitaly, postgres, and redis.
Setup a PV for minio.
- Note that the gitaly PVC should be named repo-data-gitlab-gitaly-0
Set the following values:

minio:
  replicas: 2
  persistence:
    volumeName: gitlab-minio
redis:
  persistence:
    existingClaim: gitlab-redis
postgresql:
  persistence:
    existingClaim: gitlab-postgres

Migration from Omnibus Install

See Migrate from the Linux package to the Helm chart

Docker-in-docker CI/CD

The Gitlab CI/CD is useful for building docker images.
You will need to deploy setup Gitlab runners.

Due to some issues with fastly [1], you will want to set command: ["--mtu=1300"] on your dind service containers.

Omnibus Administration

Here are notes on running your own gitlab instance.
Note: I've migrated from the Omnibus install to the helm charts.

Terms

unicorn - this is the web server portion of gitlab
sidekiq - the background job processor

Basic Commands

sudo gitlab-ctl start
sudo gitlab-ctl stop
sudo gitlab-ctl restart

LFS

LFS Administration

Edit the config in /etc/gitlab/gitlab.rb and set the following:

### Git LFS
gitlab_rails['lfs_enabled'] = true
gitlab_rails['lfs_storage_path'] = "/var/opt/gitlab/gitlab-rails/shared/lfs-objects"

Notes

If you change the LFS directory, you should run sudo gitlab-ctl reconfigure
- The LFS directory should be 700 and git:root.
- Parent directories need to have permissions 775 with git in the group or owned by user git.
- See https://docs.gitlab.com/omnibus/settings/configuration.html#disable-storage-directories-management for more details.

Email

The easiest way if you have very few users like me is to setup a separate gmail account.
Then use forwardemail.net such that the separate gmail account can send using your domain.
Then fill in the configuration.
See settings:smtp#gmail. Also set:

gitlab_rails['gitlab_email_from'] = '[email protected]'

Container Registry

In /etc/gitlab/gitlab.rb, edit the following:

registry_external_url 'https://registry.gitlab.davidl.me'

### Settings used by GitLab application
gitlab_rails['registry_enabled'] = true
gitlab_rails['registry_host'] = "registry.gitlab.davidl.me"
gitlab_rails['registry_path'] = "/var/opt/gitlab/gitlab-rails/shared/registry"

registry_nginx['enable'] = false

Then have your reverse proxy to 5000.
