title: How to containerise CodeIgniter project using Docker?
body: <p>I'm very new to Docker and I have a CodeIgniter project that I have been working on via my localhost (XAMPP) up until now. I now want to host my project on Docker using GCP.</p>
  <p>Would anyone be able to provide guidance as to how I would write a docker-compose.yml to containerise the project with redis, php, mysql and and nginx containers? Also how would I need my CI project structured for it to work?</p>
