我可以在环境变量中保存git凭证吗? [英] Can I hold git credentials in environment variables?

问题描述

我想创建一个非常简单的shell脚本，该脚本最终将被另一个应用程序调用，以更新本地git存储库:

I'd like to create a very simple shell script, which will ultimately be called by another application, that updates a local git repository:

#!/bin/bash

cd $1
sudo git pull

执行此操作时，系统会要求我提供凭据(我是从私有BitBucket存储库中提取的).

When executing this I'm asked for credentials (I'm pulling from a private BitBucket repository).

我可以(简要地)将凭证存储在环境变量中吗?

Can I ( briefly) store credentials in environment variables?

#!/bin/bash

export  GIT_USERNAME=<user>
export  GIT_PASSWORD=<pass>

cd $1
sudo git pull

以上操作无效.有什么事吗我可以以编程方式修改原始网址，但这似乎有点过分.

The above doesn't work. Would anything? I could programmatically modify the origin url but that seems a bit execessive.

推荐答案

我知道这是一个非常老的问题，但是如果您真的需要通过用户名和密码来进行HTTP基本身份验证，则可以像这样设置帮助程序:

I know that it's very old question but if you really need to pass username and password for HTTP basic authentication you can just set helper like this:

git config credential.helper '!f() { sleep 1; echo "username=${GIT_USER}"; echo "password=${GIT_PASSWORD}"; }; f'

更新:我已经在函数中添加了sleep 1.在某些环境中，可能由于比赛条件而需要它.我有2个运行Debian Jessie的虚拟机.它们具有相同的体系结构，但CPU和内核数量不同.在其中一台计算机上，辅助程序在没有sleep的情况下仍能正常工作.另一方面，事实并非如此.经过几个小时的调试，我运行strace看看发生了什么.它神奇地开始工作. strace只是使git慢一点.

UPDATE: I've added sleep 1 to the function. In some environments it may be probably needed due to race condition. I've got 2 virtual machines running Debian Jessie. They had the same architecture but different CPU and different number of cores. On one of these machines the helper was working fine without sleep. On the other one it wasn't. After few hours of debugging I run strace to see what's happening. And it magically started to work. strace just made git a little bit slower.
