Transcript

1. How to Bring Up GitLab Nestor Pestelos, Jr. @ngpestelos
3. • GitLab service from scratch (w/ demo) • Tools: terraform, CoreOS, docker-compose • Services: DigitalOcean, LetsEncrypt tl;dr
4. Why? • I run a GitLab instance for >1 year now • Fighting bit rot every day • Config management can only take you so far
5. Demo • use terraform to bring up a CoreOS host (w/ DNS) • run a few setup scripts (e.g. letsencrypt) • scp docker-compose.yml • run docker-compose • setup GitLab
6. gitlab-selfhosted.tf • terraform config DSL • “tell DigitalOcean to spin-up a host and give it a hostname” • initial DNS config (point to DO name servers)
7. gitlab-selfhosted.yml • initialize the host using cloud-config • bootstrapping newly provisioned cloud servers • generate shell scripts
8. docker-compose.yml • not the standard way to run your own GitLab • github.com/sameersbn/docker-gitlab • Containers: redis, postgresql, registry, gitlab • Data volume containers • (optional) How to use upgraded images?
9. Insights • Build generic servers • Image as primary artifact (multiple images in a single host) • Having long-running servers is OK
10. Examples • https://goo.gl/P4lGy8 (gitlab-selfhosted.tf) • https://goo.gl/b3CCKX (gitlab-selfhosted.yml) • https://goo.gl/l6ahQO (docker-compose.yml)
