Post-receive hook to deploy the code being pushed to production branch to a specific folder

post-receive

#!/bin/bash

target_branch="production"
working_tree="PATH_TO_DEPLOY"

while read oldrev newrev refname
do
    branch=$(git rev-parse --symbolic --abbrev-ref $refname)
    if [ -n "$branch" ] && [ "$target_branch" == "$branch" ]; then
    
       GIT_WORK_TREE=$working_tree git checkout $target_branch -f
       NOW=$(date +"%Y%m%d-%H%M")
       git tag release_$NOW $target_branch
    
       echo "   /==============================="
       echo "   | DEPLOYMENT COMPLETED"
       echo "   | Target branch: $target_branch"
       echo "   | Target folder: $working_tree"
       echo "   | Tag name     : release_$NOW"
       echo "   \=============================="

Deploying Code via Git Post-Receive Hook

The procedure is pretty simple. Whenever you merge your code from development branch into production branch, commit and then push to deploy_server (that is the server you want to deploy your code. It contains a remote git repository that we can push our code), the changes are deployed to the required folders in deploy_server by the post-receive hook. If you want more information about git hooks, please check http://git-scm.com/book/en/Customizing-Git-Git-Hooks. The following procedure is useful to deploy static files, and scripts.

Local:

Add a new remote to your local repository

$ git remote add deploy_server REMOTE_URL

Create production branch

$ git branch production

Do your development in development branch and merge into production to deploy to server

(production) $ git merge development

Remote:

Add the post-receive hook decribed in this gist. Do not forget to replacethe path to deploy with the PATH_TO_DEPLOY placeholder.

Local:

Simply push you commits to the newly added remote

(production) $ git push deploy_server production

remote:    | Target branch: production

remote:    \==============================
To REMOTE_URL
   92f6e8e..f260343  production -> production

When you push the code to production branch of remote:

• Post-receive hook puts your code (i.e. totally replaces the existing code via force checkout) to the directory you defined in the hook
• Adds a new tag with a name release_$releaseDateTime on remote bare repo.

This is great, thanks

cool!

A very useful bit of code and easy to follow, thanks.

It might be worth mentioning in your instructions that if you need to roll back to a previous commit you'll need to do something like git push <remote> +<commit>:<target_branch>

Lovely, I event added second if condition to push my development branch to different directory 💃

Unfortunatelly it doesn't work on Bitbucket =/
