How To Put Your Docker Image On A Diet | PHP South West

Large docker images are slow to deploy and costs can mount up when they are used on cloud infrastructure.

In this talk I will demonstrate 6 ways to reduce the size of your Docker image. Each example has been tagged as a working example that can be found on the Docker hub and GitHub.

I presented this talk at PHP South West on the 11th of October 2017
