1.1.1. 安装Helm

1.部署Helm客户端

[root@linux-node1 ~]# cd /usr/local/src
[root@linux-node1 src]# wget https://get.helm.sh/helm-v3.2.4-linux-amd64.tar.gz
[root@linux-node1 src]# tar zxf helm-v3.2.4-linux-amd64.tar.gz
[root@linux-node1 src]# mv linux-amd64/helm /usr/local/bin/

2.验证安装是否成功

[root@linux-node1 ~]# helm version
version.BuildInfo{Version:"v3.2.4", GitCommit:"b29d20baf09943e134c2fa5e1e1cab3bf93315fa", GitTreeState:"clean", GoVersion:"go1.13.7"}

1.1.2. 使用Helm部署第一个应用

3.添加仓库

[root@linux-node1 ~]# helm repo list
[root@linux-node1 ~]# helm repo add stable http://mirror.azure.cn/kubernetes/charts/
[root@linux-node1 ~]# helm repo update

4.搜索Helm应用

[root@linux-node1 helm-nginx]# helm search repo jenkins

2. Get the Jenkins URL to visit by running these commands in the same shell:
  NOTE: It may take a few minutes for the LoadBalancer IP to be available.
        You can watch the status of by running 'kubectl get svc --namespace default -w viable-seal-jenkins'
  export SERVICE_IP=$(kubectl get svc --namespace default viable-seal-jenkins --template "{{ range (index .status.loadBalancer.ingress 0) }}{{ . }}{{ end }}")
