1.1.安装helm客户端

各个版本的helm：https://github.com/helm/helm/releases

wget https://get.helm.sh/helm-v2.14.3-linux-amd64.tar.gztar -zxvf helm-v2.14.3-linux-amd64.tar.gzmv linux-amd64/helm /usr/local/bin/chmod +x /usr/local/bin/helmhelm version

1.2.安装helm tiller（server）端

离线安装请查看

1.2.1.为应用程序设置serviceaccount

kubectl create -f helm-rbac-config.yaml

kubectl patch deploy --namespace kube-system tiller-deploy -p '{"spec":{"template":{"spec":{"serviceAccount":"tiller"}}}}'

1.2.2.安装tiller

helm init --upgrade -i registry.cn-hangzhou.aliyuncs.com/google_containers/tiller:v2.14.3 --stable-repo-url [https://kubernetes.oss-cn-hangzhou.aliyuncs.com/charts](https://kubernetes.oss-cn-hangzhou.aliyuncs.com/charts)

 [root@k8s1-master1 ~]# helm version

helm reset -f

或

kubectl get -n kube-system secrets,sa,clusterrolebinding -o name|grep tiller|xargs kubectl -n kube-system delete kubectl get all -n kube-system -l app=helm -o name|xargs kubectl delete -n kube-system
