Simple CI/CD System

• This is tutorial about Simple CI/CD system. You can use simple technologies of current system to build it.

Ideas and Environment

Environment

• Tools:
  • Flyway (https://flywaydb.org/): Version control for your database.
  • Backlog: Git server
  • Chatwork: Group chat for teams
• Environment:
  • OS: Ubuntu 14.04
  • Git: 1.9.1
  • PHP: 5.5+
  • Nginx: 1.4.6
  • PostgreSQL: 9.3.16

Idea

After you Build environment for server sucessfully.

1. Create an API Pull source code automatically has method is POST (index.php): To call bash script file and send message to Chatwork.
2. Create and bash script file: Pull latest source code from Git server (Backlog) and run Database migration tool (Flyway). I have written an example (bash_deploy.sh).
3. Create ssh key by nginx user (www-data user) and add public key to Backlog server.

• Create a ssh key by nginx user :

sudo -H -u www-data bash -c 'ssh-keygen -t rsa -b 4096 -C "your_email@example.com"' 

This creates a new ssh key. Add new ssh to Git server.

4. User Backlog git webhook to trigger CI build (https://backlog.com/help/usersguide/git/userguide1710/)
5. Install php-curl extension on Server.

apt-get install -y php-curl

6. Permission for bash_deploy.sh file and source codes of project. So web service can read, write and execute them.
7. Get chatwork access token (http://download.chatwork.com/ChatWork_API_Documentation.pdf).
8. Change configuration in API to server can send message to Chatwork.
9. You can try create a pulling request on Backlog.

Goodluck!!!
