If not careful, containers can become much larger than necessary which makes them annoying to download/upload from/to a container registry.

However, with a few simple tips, it is possible to build lightweight, snappy images. In this video, I share two techniques that can help make your production images smaller!

I hope you find these helpful to make your containerized applications a bit lighter.

Cheers!
