Docker images can get very large in disk space and this can quickly become an issue during deployment of a web application.

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.

Great talk dude! Great to compare it to AB split testing. Change one thing at a time and check the result. Be interesting to have a few real examples of projects you have done this on and the savings achieved... Also how do I get a cool presenter pen?!?!

Good tips! The text was a little small unfortunately and I wouldn't have been able to follow if I didn't know Dockerfiles well

Clear content, good slides and delivery.

Great to learn how some simple changes in the Dockerfile can make such a difference in size/transfer speed and attack surface.
