6. Docker to the rescue
Infrastructure as code
Customisable setup for each project
Consistent development environment
Easy to share with other developers
Low resource use
Fast to start

7. What is Docker?

8. Docker
“Docker is an open-source project that automates the deployment of applications
inside software containers. Docker containers wrap up a piece of software in a
complete filesystem that contains everything it needs to run: code, runtime, system
tools, system libraries – anything you can install on a server.”
- Wikipedia

9. Everything in containers
● Web server: Apache / Nginx
● Development language: PHP
● Database: MySQL / MariaDB
● Database management: phpMyAdmin
● Mail client: mailhog
● Caching: redis / memcached / varnish
● Search engine: solr
● Stylesheet compilation: sass
● ...

10. Docker compose
Manage multiple containers
Define links between services
Manage storage
