Today I’d like to point out an amazing new tool: The Container Layer Analyzer, written by Dan Čermák. Dan also wrote a comprehensive blog post about it, which explains it much better than what I do here.
The tool visualizes the storage requirements of a given container as a sunburst plot (you know it from the GNOME disk usage analyzer) within your webbrowser. See it for yourself, this is the plot for the current Tumbleweed container (registry.opensuse.org/opensuse/tumbleweed):
You can easily run this on your own machine:
$ podman run --rm -p 5050:5050 ghcr.io/dcermak/container-layer-sizes:latest
Ready. Listening on :5050
After starting, the web interface is running on localhost:5050.
Checkout Dan’s blog post for more info or head directly to the GitHub repository.
Thanks Dan for creating this amazing tool for us!
