git配置——local receive.denyCurrentBranch updateInstead

在Git 2.3中添加了一个很好的可能性:https://github.com/git/git/blob/v2.3.0/Documentation/config.txt#L2155

您在服务器存储库上设置它，如果工作树是干净的，它也会更新工作树。

在2.4中有进一步的改进，包括push-to-checkout钩子和未出生分支的处理。

示例用法:

git init server
cd server
touch a
git add .
git commit -m 0
git config --local receive.denyCurrentBranch updateInstead

cd ..
git clone server local
cd local
touch b
git add .
git commit -m 1
git push origin master:master

cd ../server
ls

输出:

a
b

这确实有以下GitHub公告中提到的缺点:

Your server will contain a .git directory containing the entire history of your project. You probably want to make extra sure that it cannot be served to users! During deploys, it will be possible for users momentarily to encounter the site in an inconsistent state, with some files at the old version and others at the new version, or even half-written files. If this is a problem for your project, push-to-deploy is probably not for you. If your project needs a "build" step, then you will have to set that up explicitly, perhaps via githooks.

但是所有这些点都超出了Git的范围，必须由外部代码来处理。因此，从这个意义上说，这和Git钩子一起是最终的解决方案。

我的方法是在我的部署服务器上有一个裸露的Git存储库，我在那里推送更改。然后我登录到部署服务器，更改到实际的web服务器文档目录，并执行git拉取。我没有使用任何钩子来自动地做这个，这似乎比它的价值更麻烦。

我最终创建了我自己的基本部署工具，它会自动从repo - https://github.com/jesalg/SlimJim -下拉新的更新，基本上它会监听github的接收后钩子，并使用代理来触发更新脚本。

使用下面的更新后文件:

复制你的。git目录到你的web服务器 在你的本地副本上，修改你的.git/config文件，并添加你的web服务器作为远程服务器: (远程“生产”) Url = username@webserver:/path/to/htdocs/.git 在服务器上，用下面的文件替换。git/hooks/post-update 添加对文件的执行访问(同样是在服务器上): Chmod +x .git/hooks/post-update 现在，只要本地推送到你的web服务器，它就会自动更新工作副本: Git推送生产

# This hook does two things:
#
#  1. update the "info" files that allow the list of references to be
#     queries over dumb transports such as http
#
#  2. if this repository looks like it is a non-bare repository, and
#     the checked-out branch is pushed to, then update the working copy.
#     This makes "push" function somewhat similarly to darcs and bzr.
#
# To enable this hook, make this file executable by "chmod +x post-update".

我对基督徒解决方案的看法。

git archive --prefix=deploy/  master | tar -x -C $TMPDIR | rsync $TMPDIR/deploy/ --copy-links -av username@server.com:/home/user/my_app && rm -rf $TMPDIR/deploy

存档主分支到tar 解压tar档案到系统临时文件夹的部署目录。 Rsync更改到服务器 从临时文件夹中删除部署目录。

对于post-receive hook，我使用了两种解决方案:

部署方案1

#!/bin/bash 
#  /git-repo/hooks/post-receive - file content on server (chmod as 755 to be executed)
# DEPLOY SOLUTION 1 

    export GIT_DIR=/git/repo-bare.git
    export GIT_BRANCH1=master
    export GIT_TARGET1=/var/www/html
    export GIT_BRANCH2=dev
    export GIT_TARGET2=/var/www/dev
    echo "GIT DIR:  $GIT_DIR/"
    echo "GIT TARGET1:  $GIT_TARGET1/"
    echo "GIT BRANCH1:  $GIT_BRANCH1/"
    echo "GIT TARGET2:  $GIT_TARGET2/"
    echo "GIT BRANCH2:  $GIT_BRANCH2/"
    echo ""

    cd $GIT_DIR/

while read oldrev newrev refname
do
    branch=$(git rev-parse --abbrev-ref $refname)
    BRANCH_REGEX='^${GIT_BRANCH1}.*$'
    if [[ $branch =~ $BRANCH_REGEX ]] ; then
        export GIT_WORK_TREE=$GIT_TARGET1/.
        echo "Checking out branch: $branch";
        echo "Checking out to workdir: $GIT_WORK_TREE"; 

        git checkout -f $branch
    fi

    BRANCH_REGEX='^${GIT_BRANCH2}.*$'
    if [[ $branch =~ $BRANCH_REGEX ]] ; then
        export GIT_WORK_TREE=$GIT_TARGET2/.
        echo "Checking out branch: $branch";
        echo "Checking out to workdir: $GIT_WORK_TREE"; 

        git checkout -f $branch
    fi
done

部署方案2

        rm -rf $GIT_TEMP_DIR2
    fi
done

这两种解决方案都基于本文中提供的早期解决方案。

请注意, 美元BRANCH_REGEX = ' ^ $ {GIT_BRANCH1}。” 过滤匹配“master”或“dev*”字符串的分支名称，如果推送的分支匹配，则部署工作树。 这使得将开发版本和主版本部署到不同的位置成为可能。

DEPLOY SOLUTION 1仅删除文件，这些文件是repo的一部分，并由提交删除。比部署方案2快。

DEPLOY SOLUTION 2的优势在于，它将从生产目录中删除添加到服务器端的任何新文件，无论这些文件是否添加到repo。它将永远是回购的干净的欺骗。比部署方案1慢。
