安装Helm
一:
1、下载helm-v2.10.0-linux-amd64.tar.gz 地址:https://github.com/kubernetes/helm/releases
2,解压缩 tar -zxvf helm-v2.10.0-linux-amd64.tar.gz
3,mv linux-amd64/helm /usr/local/bin/helm
4,helm version
5,目前只能查看到客户端的版本,服务器还没有安装。
helm 有很多子命令和参数,为了提高使用命令行的效率,通常建议安装 helm 的 bash 命令补全脚本,方法如下:
helm completion bash > .helmrc
echo "source .helmrc" >> .bashrc
source .bashrc
二、安装tiller服务端 (不能科学上网,使用国内镜像)
1、docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/tiller:v2.10.0
2、 权限配置不然会报这种错 no release found
kubectl create serviceaccount --namespace kube-system tiller
kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller
kubectl patch deploy --namespace kube-system tiller-deploy -p '{"spec":{"template":{"spec":{"serviceAccount":"tiller"}}}}' (此项高版本或许不起效)
3、 helm init -i registry.cn-hangzhou.aliyuncs.com/google_containers/tiller:v2.10.0 (我使用的)
或
helm init --service-account tiller --upgrade -i registry.cn-hangzhou.aliyuncs.com/google_containers/tiller:v2.10.0 --skip-refresh
helm init常用配置项如下:
--canary-image:安装金丝雀build
--tiller-image:安装指定image
--kube-context:安装到指定的kubernetes集群
--tiller-namespace:安装到指定的namespace中
--upgrade:如果tiller server已经被安装了,可以使用此选项更新镜像
--service-account:用于指定运行tiller server的serviceaccount,该account需要事先在kubernetes集群中创建,且需要相应的rbac授权
4,helm version
Client: &version.Version{SemVer:"v2.10.0", GitCommit:"9ad53aac42165a5fadc6c87be0dea6b115f93090", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.10.0", GitCommit:"9ad53aac42165a5fadc6c87be0dea6b115f93090", GitTreeState:"clean"}
5、查看tiller的Service
[^_^] linux02 ~# kubectl get services -n kube-system
tiller-deploy ClusterIP 10.103.12.239 <none> 44134/TCP 15m
查看tiller的Deployment
[^_^] linux02 ~# kubectl get deployment -n kube-system
tiller-deploy 1 1 1 1 16m
查看tiller的Pod
[^_^] linux02 ~# kubectl get pods -n kube-system
tiller-deploy-56dd949bd5-t7kq5 1/1 Running 0 16m
