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_helm.sh
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!
