Helm之于Kubernetes好比yum之于Red Hat Enterprise Linux，或者apt-get之于Ubuntu。

Helm是由helm CLI和Tiller组成，是典型的Client/Server应用。helm运行于客户端，提供命令行界面；Tiller应用运行于Kubernetes内部。

在Jerry之前的文章 里曾经介绍过手动下载Helm安装包，解压后把执行文件拷贝到环境变量的做法。

其实还有另外一种全自动的做法，使用安装脚本自动安装。

1. 自动下载安装脚本

curl   > get_

打开脚本，可以看到helm安装的环境变量HELM_INSTALL_DIR为/usr/local/bin:

2. chmod 700 get_helm.sh

./get_helm.sh:

3. 执行helm init, 看到Happy Helming消息，说明安装成功。

Creating /root/.helm

Creating /root/.helm/repository

Creating /root/.helm/repository/cache

Creating /root/.helm/repository/local

Creating /root/.helm/plugins

Creating /root/.helm/starters

Creating /root/.helm/cache/archive

Creating /root/.helm/repository/repositories.yaml

Adding stable repo with URL: 

Adding local repo with URL: 

$HELM_HOME has been configured at /root/.helm.

Tiller (the Helm server-side component) has been installed into your Kubernetes Cluster.

Please note: by default, Tiller is deployed with an insecure 'allow unauthenticated users' policy.

To prevent this, run  helm init  with the --tiller-tls-verify flag.

Happy Helming!
