Git挂钩可以在子模块更改时更新超级项目? [英] Git hook to update superproject on submodule change?

问题描述

我有三个git存储库:A，B和C. C是一个包含子模块A和B的超级项目，跟踪每个子模块各自的主分支.

I have three git repositories: A, B, and C. C is a superproject including submodules A and B, tracking each submodule's respective master branch.

更改A或B的主分支时，我必须在C中执行以下操作:

When the master branch of A or B is changed, I must do the following in C:

git submodule update --remote
git add A
git add B
git commit -m "Update submodule A or B"
git push

此时，将执行从C进行的自动构建和部署.

At this point an automated build and deploy from C is executed.

我正在寻找简化此过程的方法.理想情况下，对A或B的master分支的任何提交都会触发钩子来更新，提交和推送到C.有什么想法可以实现这一目标吗?

I'm looking for ways to streamline this process. Ideally, any commit to the master branch of A or B would trigger a hook to update, commit, and push to C. Any ideas how to achieve this?

如果有我应该了解的特定于供应商的功能，则我将Azure DevOps用于git托管，并将Azure Pipelines用于构建和部署过程.

In case there's a vendor-specific feature I should be aware of, I'm using Azure DevOps for the git hosting and Azure Pipelines for the build and deploy process.

推荐答案

您可以使用git post-commit

You can use a git post-commit hook, when you do a commit in the submodules the hook will be executed and will do the commands.

1. 转到每个子模块存储库.

2. 使用以下内容创建文件 .git/hooks/post-commit :

#!/bin/sh

branch="$(git rev-parse --abbrev-ref HEAD)"

if [ "$branch" = "master" ]; then
  cd {super repo location}
  git submodule update --remote
  git add A
  git add B
  git commit -m "Update submodule A or B"
  git push
fi

使其可执行(在 Windows 上不是必需的):

Make it executable (not required on Windows):

$ chmod +x .git/hooks/pre-commit
