helm在kubernetes环境中搭建

1.安装helm

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.gz

tar -zxvf helm-v2.14.3-linux-amd64.tar.gz

mv linux-amd64/helm /usr/local/bin/

chmod +x /usr/local/bin/helm

helm 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
Client: &version.Version{SemVer:"v2.14.3", GitCommit:"0e7f3b6637f7af8fcfddb3d2941fcc7cbebb0085", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.14.3", GitCommit:"0e7f3b6637f7af8fcfddb3d2941fcc7cbebb0085", GitTreeState:"clean"}

 #如果报错如下：

Client: &version.Version{SemVer:"v2.14.3", GitCommit:"bbc1f71dc03afc5f00c6ac84b9308f8ecb4f39ac", GitTreeState:"clean"}
E0921 16:19:09.448738   24295 portforward.go:331] an error occurred forwarding 39401 -> 44134: error forwarding port 44134 to pod 5b85aa2aa4347d59ea30edf466a7e01a198780151d30644a16b5cab4ceb2b83d, uid : unable to do port forwarding: socat not found.
Error: cannot connect to Tiller

#解决办法：在k8s的node节点安装ssocat即可解决

$sudo yum install socat

1.2.3.卸载Helm镜像等k8s资源

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
