What made your container fat?

Visualizing the size of Container Layers


Keeping the size of of your containers small is more important than ever, especially when distributing container images for others to build upon them. However, once multiple container layers get involved, even the data collection aspect becomes challenging and most existing tools do not primarily focus on visualization.

We will present a simple tool that we created for this: it is a simple web app that produces sunburst graphs for each layer of a container image and can thereby aid you in finding out where the size bloat comes from. Go and grab it from https://github.com/dcermak/container-layer-sizes and give it a spin yourself!
