Docker is the world’s leading software container platform. Developers use Docker to eliminate “works on my machine” problems when collaborating on code with co-workers. Operators use Docker to run and manage apps side-by-side in isolated containers to get better compute density. Enterprises use Docker to build agile software delivery pipelines to ship new features faster, more securely and with confidence for both Linux and Windows Server apps.

CodeIgniter is a powerful PHP framework with a very small footprint, built for developers who need a simple and elegant toolkit to create full-featured web applications. If you want to learn more then head to their official website that has great documentation as well at https://codeigniter.com/

If you’re excited about using Docker for your development and you are working on a CodeIgniter (CI) based PHP project then you are lucky. It is very easy to setup CI based project with Docker. Just follow the instructions below to setup a fresh CI project with Docker.
docker-compose up -d
It will spin up two containers. One for app itself with Nginx and another for MariaDB for your DB. App container will create a directory in your project folder and install CodeIgniter in it.
