What you can do with it
- Browse the file tree of each layer in a Docker image to see what changed
- Check an image efficiency score and the amount of wasted space to find ways to shrink it
- Run it in a CI pipeline to fail builds when an image wastes too much space
Make money with it
A freelancer could offer container image optimisation audits for small teams, using it to show where space is wasted.
