生产环境的开源容器管理平台--Rancher入门教程(5):自定义Catalog工具

Rancher是一个用于部署和管理生产环境的容器的开源平台,它与Kubernetes/Mesos/Docker Swarm进行集成。使得在任何硬件环境上容器化应用变得触手可及。在这个系列的教程中我们将会学习如何使用rancher, 上篇文章介绍了如何在rancher中添加自定义的catalog，由于较为繁琐，本文介绍一下相关自动化工具。

yo rancher-catalog

在上篇文章中介绍了自定义catalog的方法，但是文件较多，限制很多，从文件名到内容很小的地方都可能造成不能正常显示，使用npm的rancher-catalog这个小工具可以绕开一部分问题。

安装

npm install -g yo
npm install -g generator-rancher-catalog

执行方法

yo rancher-catalog

demo

生成

设定

确认

rancher-cattle-autocatalog

使用npm的yo，前提是还必须要安装npm，所以也可以使用rancher-cattle-autocatalog进行处理。

warning: push.default is unset; its implicit value is changing in
Git 2.0 from 'matching' to 'simple'. To squelch this message
and maintain the current behavior after the default changes, use:

git config --global push.default matching

To squelch this message and adopt the new behavior now, use:

git config --global push.default simple

See 'git help config' and search for 'push.default' for further information.
(the 'simple' mode was introduced in Git 1.7.11. Use the similar mode
'current' instead of 'simple' if you sometimes use older versions of Git)

上篇文章的例子即为使用这种方法自动生成。熟悉格式之后不用任何工具也是一样。
