Git: Auto Deploy Server

Step-1: create git directory (/home/ubuntu/site.git).
$/home/ubuntu/site.git> git init --bare

Step-2: your deployment path (/home/ubuntu/www) from where site will be served.
Step-3: Inside site.git folder move to hooks folder and create a file named post-receive.
paste below code inside it.

#!/bin/bash

deploy="yes"
while read oldrev newrev refname
do
    ref=$(git rev-parse --symbolic --abbrev-ref $refname)
    if [ -n "$ref" ] && [ "master" == "$ref" ]; then
       work_tree="/home/ubuntu/www"
       branch="master"
    elif [ -n "$ref" ] && [ "dev" == "$ref" ]; then
       work_tree="/home/ubuntu/www2"
       branch="dev"
    else
       echo "Got $ref branch. Doing Nothing."
       deploy="no"
    fi
done

if [ "yes" == "$deploy" ]; then
   git --work-tree=$work_tree --git-dir=/home/ubuntu/site.git checkout $branch -f
   NOW=$(date +"%Y%m%d-%H%M%S")
   git tag release_$NOW $target_branch
   echo "    //==============================="
   echo "   || DEPLOYMENT COMPLETED"
   echo "   || Target branch: $branch"
   echo "   || Target folder: $work_tree"
   echo "   || Tag name     : release_$NOW"
   echo "   \\=============================="
fi

Step-4: Give execution permissions

chmod +x /hooks/port-receive


Step-5: add remote git in you local git repo

git remote add live ssh://ec2-user@IPOrPublicDNS:/home/ubuntu/site.git

git push/pull live "branch"
