Cleaning Up Docker Images

December 30, 2019

After a while of using docker locally for development, you may notice that you have a lot of images and containers laying around on your disk that you no longer use. This post shows you an effective way to clean up 50 of GB or more of disk space. The first, best thing to do is clean up dangling images. These are docker images that are not referenced by a container.


Over the past few months, I’ve been getting my hands dirty with containers, Docker, and Kubernetes in an effort to get some hands on experience working toward microservices. I’ve been building up a small application to generate and serve Sudoku puzzles. My original goal was to see how many puzzles with unique solution I could actually find, but that’s another post entirely. There are already many great tutorials about Docker and Kubernetes on Google Container Engine, so I won’t go into getting started details here.
