ks8/openshift下安装、卸载helm

环境

openshift 3.11（k8s环境请将oc命令替换成kubectl）

1. 安装helm client端

• 手工安装,从官方后去下载包。https://github.com/helm/helm/releases

unzip helm.zip
chmod +x helm
mv helm /usr/local/bin

• 自动安装helm

 curl https://raw.githubusercontent.com/kubernetes/helm/master/scripts/get | bash

2. 创建serviceaccount并授权

export TILLER_NAMESPACE=kube-system  

oc create serviceaccount --namespace kube-system tiller

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

3. 安装

执行init子命令，镜像tag应该与client端保持一致

helm init  --service-account=tiller --tiller-namespace=kube-system  --tiller-image=registry.cn-hangzhou.aliyuncs.com/google_containers/tiller:v2.13.0 

检查helm pod是否running

oc get po --namespace kube-system

4. 卸载

• 卸载方式一：服务端卸载

oc delete deployment tiller-deploy --namespace kube-system

• 卸载方式二：服务端、chart应用卸载

helm reset
