kubernetes 1.12.1 高可用安装之部署Helm

1.部署Helm客户端

[root@master01 ~]# wget https://storage.googleapis.com/kubernetes-helm/helm-v2.9.1-linux-amd64.tar.gz
[root@master01 ~]# tar zxf helm-v2.9.1-linux-amd64.tar.gz
[root@master01 ~]# mv linux-amd64/helm /usr/local/bin/

2.初始化Helm并部署Tiller服务端

[root@master01 ~]# helm init --upgrade -i \
 registry.cn-hangzhou.aliyuncs.com/google_containers/tiller:v2.9.1 \
--stable-repo-url https://kubernetes.oss-cn-hangzhou.aliyuncs.com/charts

3.所有节点安装socat命令

[root@master01 ~]# yum install -y socat

4.验证安装是否成功

[root@master01 ~]# helm version
Client: &version.Version{SemVer:"v2.9.1", GitCommit:"20adb27c7c5868466912eebdf6664e7390ebe710", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.9.1", GitCommit:"20adb27c7c5868466912eebdf6664e7390ebe710", GitTreeState:"clean"}

5.查看helm tiller的服务

[root@master01 ~]#  kubectl get pod --all-namespaces|grep tiller
kube-system   tiller-deploy-98f7f7564-ppwcx          1/1       Running   0          4m

6.使用Helm部署第一个应用

6.1创建服务账号

[root@master01 ~]# kubectl create serviceaccount --namespace kube-system tiller
serviceaccount "tiller" created

6.2.创建集群的角色绑定

[root@master01 ~]# kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller
clusterrolebinding.rbac.authorization.k8s.io "tiller-cluster-rule" created

6.3.为应用程序设置serviceAccount

[root@master01 ~]# kubectl patch deploy --namespace kube-system tiller-deploy -p '{"spec":{"template":{"spec":{"serviceAccount":"tiller"}}}}'
deployment.extensions "tiller-deploy" patched

6.4.搜索Helm应用

[root@master01 ~]# helm search jenkins
