Manifests to deploy GitLab on Kubernetes

Installation process described in blog

Helm chart based on this manifests

2016-11-24 Update #1 after post was published

Bump versions

• gitlab-runner:v1.8.0
• gitlab:8.16.3
• postgresql:9.5-3
• redis:3.2.4 (official redis container)

Change in ingress

• SSH is now available through 1022 service post.
• NGINX settings is now configurable with configmap nginx-settings-configmap.yml. Which currently sets body-size to 0 and increases timeouts to avoid timeouts.

TL;DR

# create gitlab namespace
> $ kubectl create -f gitlab-ns.yml

# deploy redis
> $ kubectl create -f gitlab/redis-svc.yml
> $ kubectl create -f gitlab/redis-deployment.yml

# deploy postgres
> $ kubectl create -f gitlab/postgresql-svc.yml
> $ kubectl create -f gitlab/postgresql-deployment.yml

# deploy gitlab itself
> $ kubectl create -f gitlab/gitlab-svc.yml
> $ kubectl create -f gitlab/gitlab-svc-nodeport.yml
> $ kubectl create -f gitlab/gitlab-deployment.yml

# deploy ingress controller
> $ kubectl create -f ingress/default-backend-svc.yml

Deploying GitLab Runner

# deploy Minio
kubectl create -f minio/minio-svc.yml
kubectl create -f minio/minio-deployment.yml

# check that it's running
kubectl get pods --namespace=gitlab

# check logs for AccessKey and SecretKey
> $ kubectl logs -f minio-2719559383-y9hl2 --namespace=gitlab
