Need to do surgery on your Docker images?

Have you ever needed to do a deep dive into your docker images to find out exactly what changed?

If your systems are as sophisticated as the systems I work with, your docker images have at least a few layers to them and keeping track of what is installed in each layer can be challenging.

Docker Dive is an opensource tool that will give you better insight into what has changed in each layer.

One suggested way of using it is to wire it into your build pipeline to test to see if you are wasting space.

They do admit that the UI has a “beta quality”, but that is how great open source projects start.

I think it shows great potential even in its current state and am eager to see where it goes.

Special thanks to Tim L for putting this on my radar.

Question for you:
