# How To Put Your Docker Image On A Diet
A talk by [Peter Fisher](http://peterfisher.me.uk/event/how-to-put-your-docker-image-diet/)
The application is a very simple Symfony 4.3.4 web app.
Each tag demonstrates how to reduce the file size of the Docker image which is being built.
The talk was first given at PHP South Wales
