CentOS7下安装helm

1、先下载2.11.0版本

记住就下这个版本，其他版本要确认你有相应的镜像源，否则装不上

wget https://get.helm.sh/helm-v2.11.0-linux-amd64.tar.gz
tar -xf helm-v2.15.2-linux-amd64.tar.gz
cd linux-amd64/
cp helm /usr/local/bin/

配置sa以及绑定集群
vi tiller.yaml

apiVersion: v1
kind: ServiceAccount
metadata:
  name: tiller
  namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1beta1
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 create -f rbac-config.yaml
serviceaccount/tiller created
clusterrolebinding.rbac.authorization.k8s.io/tiller created

2、下载镜像

docker pull fishead/gcr.io.kubernetes-helm.tiller:v2.11.0

下载完查看一下

docker images|grep till

镜像源没问题开始安装

3、初始化创建服务端

./helm init --service-account tiller --tiller-image fishead/gcr.io.kubernetes-helm.tiller:v2.11.0 --skip-refresh

执行完后查看pod

kubectl get pods -n kube-system

也可以用

helm version

正常如下，否则会报错

[root@master1 linux-amd64]# helm version
Client: &version.Version{SemVer:"v2.11.0", GitCommit:"2e55dbe1fdb5fdb96b75ff144a339489417b146b", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.11.0", GitCommit:"2e55dbe1fdb5fdb96b75ff144a339489417b146b", GitTreeState:"clean"}

4、出错

你可能会看到下面的界面

NAME                             READY   STATUS             RESTARTS   AGE
tiller-deploy-6f6fd74b68-qvlzx   0/1     ImagePullBackOff   0          8m43s

编辑下配置文件

kubectl edit deployment tiller-deploy -n kube-system

apiVersion: extensions/v1beta1
kind: Deployment

编辑下配置文件，看看镜像对不对，应该是镜像 fishead/gcr.io.kubernetes-helm.tiller

image: gcr.io/kubernetes-helm/tiller:v2.11.0

如果还是有问题，删除tiller，检查版本，检查每一步，重新上述步骤
删除tiller用下面的语句

helm reset -f
