Wercker AWS CI CD example App

Fork this repository
Setup a wercker account and have it point to the repo you just forked

go to the app settings and create an ssh key

add your public key in your aws instance's authorized_keys file

$ ssh YOUR_USER@YOUR_SERVER_IP
$ vi ~/.ssh/authorized_keys

past the public key you got from wercker into the next line

go back to your wercker settings and create a deployment target called aws (doesn't have to be but we will do that)

Add variables into your target
add the ssk key as a variable in your deployment target calling it SSH_KEY
add the variable your HOST, your USER, your REPO_URL and the name of your APP as variables as well

You should windup with a target that looks something like this

Don't forget to Save

Add update_server.sh file into your server's home (you already did that if you're coming from the se-tutrial lab)

This file assumes you're using nvm and pm2

#!/bin/bash

[[ -s $HOME/.nvm/nvm.sh ]] && . $HOME/.nvm/nvm.sh
nvm use 5.9
if [ ! -d "$APP" ]; then
   git clone "$REPO_URL" "$APP"
   cd "$APP"
else
   cd "$APP"
   git pull origin master -f
fi

npm install
cd ..
pm2 stop all
pm2 start "$APP"

exit 0

$ chmod u+x update_server.sh

make sure port 80 is open otherwise you should add a port variable to the script and declare it before running the app

sudo iptables -A INPUT -p tcp --dport 80 -j ACCEPT
sudo iptables -A OUTPUT -p tcp --dport 80 -j ACCEPT
sudo apt-get install libcap2-bin
sudo setcap cap_net_bind_service=+ep /usr/local/bin/node

Now your setup should be ready

To test this out simply clone this repo
and change in it (say change the welcome message)
then add commit and push it to master

After that checkout the app on wercker

the wercker.yml file is explained back in the se-tutrial lab
