Ask HN: What are the disadvantages of Docker?

I feel your pain on the disk usage, especially when rapidly making changes and building with `docker-compose up --build`. However `docker system prune` is your friend here.

It would be great if it were automated and a little smarter, it basically leaves no survivors, but for all the advantages of Docker this isn't so bad.

There are some community written garbage collectors out there that are good but none mainlined yet.

I do agree that docker's pros are worth the cons. Anyone who has every migrated a large application that they didn't have good documentation on the installation or configuration process (especially ones which you have written and forgot about) knows how valuable good, self-contained, packaging is.

I've used docker-gc by Spotify for production nodes that needed cleaning up and it's worked pretty well.
