uuid - 如何获取 dotCloud 应用程序的 UUID？

Question

一些 PaaS 提供商有一个APPLICATION_UUID环境变量，这显然是唯一的（至少在他们的平台上）。

DotCloud 有类似的东西吗？我在environment.json中没有找到类似的东西

Answer 1

There isn't a UUID, but if you are trying to tell different instances from each other, you can use the dotcloud configuration values from the environment.json file:

DOTCLOUD_PROJECT : which is the name you have given the dotcloud application DOTCLOUD_SERVICE_NAME : which is the name you give each service (typically www, or data, etc) DOTCLOUD_SERVICE_ID : the instance number of a particular instance, starting at 0

If you concatenate the 3, it would create a unique identifier across all of your dotcloud applications, services, and instances.

Answer 2

没有这样的东西暴露在外面。你需要它做什么，也许我可以建议一个替代方案？
