1. Create GKE cluster (server)

2. Login GCP (client)

https://fastfoodcoding.com/questions/1509294958998/how-to-logout-from-an-account-on-gcloud-sdk If you want to logout from all the accounts run the following command

$ gcloud auth revoke --all

If you want to logout from a specific account then run the following command

$ gcloud auth revoke <your_account>

If you want to login with a different account, you can run the following command

$ gcloud auth login

This will take you to the Google's login page where you can choose the account with which you want to login

3. Install Helm

https://jimmysong.io/kubernetes-handbook/practice/helm.html 创建tiller的serviceaccount和clusterrolebinding

kubectl create serviceaccount --namespace kube-system tiller
kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller

然后安装helm服务端tiller

helm init -i jimmysong/kubernetes-helm-tiller:v2.8.1

或

helm init --service-account tiller

pod 啟動需要一些時間

5. Define your Chart

Helm 提供快速 create Chart 的指令， 並且可以透過 --dry-run --debug 來預先瀏覽產出的設定是不是你想要的，確認後才真正的執行安裝：

$ helm create example-chart
$ helm install . --dry-run --debug
$ helm install . --name example-chart --namespace example-chart
