kubernetes-安装Helm

Helm是什么?

Helm可以管理Kubernetes应用程序-Helm Charts帮助您定义，安装和升级最复杂的Kubernetes应用程序。

下载Helm 在https://github.com/helm/helm/releases

最新发布版本是这个，使用wget下载

wget https://get.helm.sh/helm-v2.16.0-linux-amd64.tar.gz

 下的太慢了，我就直接用本机下载过来Xftp传上去了。

然后执行：

tar -zxvf helm-v2.16.0-linux-amd64.tar.gz
mv linux-amd64/helm /usr/local/bin/helm

 基于角色的访问控制（RABC） ：rabc-tiller.yml

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

 运行:

kubectl apply -f rabc-tiller.yml

查看helm版本信息:

helm version

Client: &version.Version{SemVer:"v2.16.0", GitCommit:"e13bc94621d4ef666270cfbe734aaabf342a49bb", GitTreeState:"clean"}
Error: could not find tiller

安装helm,  tiller使用阿里云源(Server/Client版本要一致):

helm init --service-account tiller --tiller-image registry.cn-hangzhou.aliyuncs.com/google_containers/tiller:v2.16.0 --stable-repo-url https://kubernetes.oss-cn-hangzhou.aliyuncs.com/charts

$HELM_HOME has been configured at /root/.helm.

Tiller (the Helm server-side component) has been installed into your Kubernetes Cluster.

Please note: by default, Tiller is deployed with an insecure 'allow unauthenticated users' policy.
To prevent this, run `helm init` with the --tiller-tls-verify flag.
For more information on securing your installation see: https://docs.helm.sh/using_helm/#securing-your-helm-installation

 再查看版本信息:

helm version

Client: &version.Version{SemVer:"v2.16.0", GitCommit:"e13bc94621d4ef666270cfbe734aaabf342a49bb", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.16.0", GitCommit:"e13bc94621d4ef666270cfbe734aaabf342a49bb", GitTreeState:"clean"}

就安装成功了

如果出现错误可使用以下命令:

helm reset :  重置
rm -rf /root/.helm  :  删除helm配置
kubernetes删除helm和tiller相关配置:   
kubectl delete deployment tiller-deploy -n kube-system
kubectl delete service tiller-deploy -n kube-system

如果pod删除不掉，可强制删除:

kubectl delete pod <pod name> --namespace=<pod namespace> --grace-period=0 --force
