在结构中添加环境变量的最佳方法? [英] Best way to add an environment variable in fabric?

问题描述

我想将一些值从Fabric传递到远程环境中，但我没有很好的方法来做到这一点.到目前为止，我想出的最好的方法是:

I would like to pass a few values from fabric into the remote environment, and I'm not seeing a great way to do it. The best I've come up with so far is:

with prefix('export FOO=BAR'):
    run('env | grep BAR')

这似乎确实有效，但似乎有点破绽.

This does seem to work, but it seems like a bit of a hack.

我查看了GIT存储库，它看起来像是 issue#263 .

I looked in the GIT repository and it looks like this is issue #263.

推荐答案

从Fabric 1.5(已发布)开始，

As of fabric 1.5 (released), fabric.context_managers.shell_env does what you want.

    with shell_env(FOO1='BAR1', FOO2='BAR2', FOO3='BAR3'):
        local("echo FOO1 is $FOO1")
