安装Helm

---
  • 官方参考文档：https://helm.sh/docs/intro/quickstart/
  • Helm的安装方式有两种：预编译的二进制程序和源码编译安装。
  • Helm项目托管在GitHub之上，项目地址为https://github.com/helm/helm/releases。
  • Helm的运行依赖于本地安装并配置完成的kubectl方能与运行于Kubernetes集群之上的Tiller服务器进行通信，因此，运行Helm的节点也应该是可以正常使用kubectl命令的主机，或者至少是有着可用kubeconfig配置文件的主机。

NOTES:
Thank you for installing Helm Dashboard.
Helm Dashboard can be accessed:
  * Within your cluster, at the following DNS name at port 8080:

    helm-dashboard.helm.svc.cluster.local

  * From outside the cluster, run these commands in the same shell:

    export POD_NAME=$(kubectl get pods --namespace helm -l "app.kubernetes.io/name=helm-dashboard,app.kubernetes.io/instance=helm-dashboard" -o jsonpath="{.items[0].metadata.name}")
    export CONTAINER_PORT=$(kubectl get pod --namespace helm $POD_NAME -o jsonpath="{.spec.containers[0].ports[0].containerPort}")
    echo "Visit http://127.0.0.1:8080 to use your application"
    kubectl --namespace helm port-forward $POD_NAME 8080:$CONTAINER_PORT
