软件介绍

Nulecule是一款用于快速打包复杂多样化应用的格式，同时确保所有实例顺利部署。

Nulecule规格亮点：

• Application description and context maintained in a single container through extensible metadata

• Composable definition of complex applications through inheritance and composition of containers into a single, standards-based, portable description.

• Simplified dependency management for the most complex applications through a directed graph to reflect relationships.

• Container and orchestration engine agnostic, enabling the use of any container technology and/or orchestration technology

部署用户体验

Option 1: Non-interactive defaults

[sudo] atomic run projectatomic/helloapache

Option 2: Unattended

1.用下列内容创建answers.conf 文件

[general]
provider = kubernetes

[helloapache-app]
image = centos/httpd # optional: choose a different image
hostport = 80        # optional: choose a different port to expose

2.从当前工作目录运行应用程序

$ [sudo] atomic run projectatomic/helloapache
...
helloapache

3.作为一个单独额外实验，除去kubernetes pod，改变供应商为“docker”，然后重新运行该应用程序，看看它在本地docker得到的部署。

Option 3: Install and Run

1.利用atomic install下载应用程序文件

[sudo] atomic install projectatomic/helloapache

2.重命名answers.conf.sample

mv answers.conf.sample answers.conf

3.编辑answers.conf，如果需要审查文件，然后运行

$ [sudo] atomic run projectatomic/helloapache
...
helloapache
