Helm chart to install Gitlab

This chart is based on my manifests for manual deployment with lots of improvements.

Some of the features:

• Fully automated installation of Gitlab.
• Register and manage Letsencrypt certificates with kube-lego
• Deploys PostgreSQL, Redis and Minio as part of the setup
• Deploys fully configured Docker registry with external domain (letsencrypt) and integration with gitlab.
• Semi-automatic creating of Runner
• Ability to customize any of the environment variables

Requirements

• Kubernetes 1.5 (for StatefulSets support)
• PV support on the underlying infrastructure
• Helm 2.2.0 (for conditions and flags support)

TODO:

• splitting registry/runner into separate charts
• Add support for gitlab pages
• Upgrade to v9
• [] testing/refactoring
• [] more flexible runner configuration
• [] monitoring of the whole thing in Prometheus
