Posted 2021-07-02 温茶又折花

下载安装包，并解压

wget https://get.helm.sh/helm-v2.15.2-linux-amd64.tar.gz
tar -xvf helm-v2.15.2-linux-amd64.tar.gz
cd helm-v2.15.2-linux-amd64/
cp helm /usr/local/bin/

初始化Helm 并安装tiller

Tiller是helm的服务器端，一般运行于kubernetes集群之上，定义tiller的ServiceAccount，并通过ClusterRoleBinding将其绑定至集群管理员角色cluster-admin，从而使得它拥有集群级别所有的最高权限
apiVersion: v1
kind: ServiceAccount
metadata:
  name: tiller
  namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: tiller
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
  - kind: ServiceAccount
    name: tiller
    namespace: kube-system

kubectl apply -f tiller-rbac.yaml

初始化并安装tiller

helm init --upgrade --service-account tiller  --tiller-image registry.cn-hangzhou.aliyuncs.com/google_containers/tiller:v2.15.2 --stable-repo-url https://kubernetes.oss-cn-hangzhou.aliyuncs.com/charts

一旦安装了 Tiller，运行 helm version 会显示客户端和服务器版本
helm version

可以在kube-system命名空间看到tiller已经部署
kubectl get pods -n kube-system | grep tiller

删除tiller
kubectl -n kube-system delete deploy tiller-deploy
