One of my docker hosts died and after some investigation I discovered the disk was full and don’t really understand why or how to resolve it given the dockers themselves are small.
I have grabbed screens from the file system and the docker output to show what I mean.
- I haven’t been able to work out which container this large file is. How do I do this?
- How do I shrink / reclaim this space?
- Is it possible to set a docker container size limits and alerts to stop the entire host crashing again?
