#Creating cluster:

Setup gcloud cli: gcloud config set project PROJECT-ID gcloud config set compute/zone COMPUTE-ZONE

Create a cluster: gcloud container clusters create my-cluster --num-nodes=1

Create IPs:

gcloud compute addresses create service-a-ip
gcloud compute addresses create front-service-ip

And specify them in my-values.yaml (if you use Linux, avoid .bak in sed commands):

export SERVICE_A_IP=$(gcloud compute addresses describe service-a-ip | grep address: | sed 's/address: //g')
export FRONT_SERVICE_IP=$(gcloud compute addresses describe front-service-ip | grep address: | sed 's/address: //g')
cp kubergang/values.yaml kubergang/my-values.yaml
sed -i .bak 's/SERVICE_A_IP/'$SERVICE_A_IP'/g' kubergang/my-values.yaml
sed -i .bak 's/FRONT_SERVICE_IP/'$FRONT_SERVICE_IP'/g' kubergang/my-values.yaml

Update IPs in DNS records for service-a.kubergang.com and the.kubergang.com

#Helm commands:

helm repo add kubergang https://anatoliistepaniuk.github.io/kube-services

helm repo update

helm search repo kubergang --versions

helm upgrade kubergang kubergang/kubergang --install --create-namespace --values=kubergang/my-values.yaml --version=1.3.6

Make changes to templates, specify new chart version in Chart.yaml, and create new chart: ./create_chart.sh

Push changes to Github.

Now you can upgrade your release to new version: helm repo update helm upgrade kubergang kubergang/kubergang --install --create-namespace --values=kubergang/my-values.yaml --version=1.3.7

Validate installation: helm test kubergang
