Thought I'd drop my xmas project in here: A visual disk usage analyser for docker images.
I have regularly found Disk Inventory X to be illuminating when fighting congestion on my macbook, but when it came to de-congesting Python docker images there was no similar tool.
Unlike Disk Inventory X and other similar tools, Whaler works from the command-line both on local dirs and images. It is built using modern front end tech: D3, Canvas, React, making it portable to all platforms including headless environments.
I have tested the tool with directories containing up to 500K nodes which should be fine for most Python Docker images. Beyond that it may chug/crash.
A live demo of my CI environment is https://treebeardtech.github.io/whaler/
