我可以在环境变量中保存 git 凭据吗? [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，最终将由另一个应用程序调用，用于更新本地 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(我从私有 BitBucket 存储库中提取).

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

我可以(简单地)将凭据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

以上行不通.会什么?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

我知道这是一个很老的问题，但是如果你真的需要为 HTTP 基本身份验证传递用户名和密码，你可以像这样设置帮助器:

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:我已将 sleep 1 添加到函数中.在某些环境中，由于竞争条件可能需要它.我有 2 台运行 Debian Jessie 的虚拟机.它们具有相同的架构，但 CPU 和内核数量不同.在其中一台机器上，助手在没有 sleep 的情况下工作正常.另一方面，它不是.经过几个小时的调试，我运行 strace 来查看发生了什么.它神奇地开始起作用.strace 只是让 git 慢了一点.

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.
