Deployment instructions using github hooks to Ec2 or any cloud VS like HEROKU does | deployment, github hooks, heroku, set production server, set server, EC2

Prepare your github repo on /var/www folder to follow the best practice.

$cd /var/www

Create a source code folder with your application name

$ sudo mkdir <Project Name>.com

Create a folder for github source code

$ sudo mkdir <Project Name>.com.git

Change to project github repo folder

$cd img-cloud-qa.com.git/

Initiate github bare to prepare folder

$sudo git init --bare

Jump to hooks to prepare your hooks for git preparation of project so you can start pushing your code to github.

$cd hooks

Now we are ready with hooks set to your project, create a post-receive file to execute your steps with shell script, below example is a node project and i am doing npm install and restarting web server.

$sudo nano post-receive


#!/bin/sh

error_exit ()
{
echo "$1" 1>&2
exit 1
}

git --work-tree=/var/www/<Project Name>.com --git-dir=/var/www/<Project Name>.com.git checkout -f
cd /var/www/<Project Name>.com || error_exit "error changing directory!. now exiting..."
npm install || error_exit "error running npm install! now exiting ..."
FOREVER_ROOT=/etc/forever forever restart -l /etc/forever/<Project Name>.log bin/www || error_exit "error starting forever server! now exiting ..."

Finally assign the proper permissions to the user to write files to to folder

$sudo chown -R deploy:deploy www/

Once all above steps done you are ready to deploy push your code to your project with below steps

git add remote <user>@<ip or host>:/var/www/<Project Name>.com.git
git push master

Ex:-

git add remote prod deploy@gsrao.xyz:/var/www/myapp.com.git
git push prod master
