Setting up gitlab from scratch

Preparing to use the Gitlab Chart

We found some decent documentation over

https://gitlab.com/charts/gitlab/blob/master/doc/installation/README.md

and ended up at:

https://gitlab.com/charts/gitlab/blob/master/doc/cloud/gke.md#scripted-cluster-creation-on-gke

Helm

curl -L https://storage.googleapis.com/kubernetes-helm/helm-v2.10.0-linux-amd64.tar.gz | tar xvz -f - --strip-components 1 -C /usr/local/bin

The Source

git clone git@gitlab.com:charts/gitlab.git ~/gitlab

GKE Setup Script

You’ll need to customize this with an project of your own.

cd ~/gitlab
export PROJECT=recodenz
./scripts/gke_bootstrap_script.sh up

Grab the external IP

export PROJECT=recodenz
export CLUSTER_NAME=gitlab-cluster
export REGION=us-central1
gcloud compute addresses create ${CLUSTER_NAME}-external-ip --region $REGION --project $PROJECT
export PROJECT=recodenz
export CLUSTER_NAME=gitlab-cluster
export REGION=us-central1
gcloud compute addresses describe ${CLUSTER_NAME}-external-ip --region $REGION --project $PROJECT --format='value(address)'
