I’m looking for some way to clean up the contents of /var/lib/docker/overlay (or /var/lib/docker/overlay2 with overlay2 - I run both, but on different nodes, both seem to have this issue). Is there any way to map the contents in there to what owns it? We have some CI runners that nightly do the eq…

So I just went through this. I read a lot of posts about how overlay doesn’t use space. This is not an entirely accurate statement. Depending on what you are doing in your container and how it and the application it runs are configured, you could end up with a large overlay directory. Overlay become…

I was having some issues with a large overlay and the thread I’m replying to helped me identify the diff which was chewing up a lot of disk space. In my case it had some large back-up files sitting inside it. I just deleted those back-up files and freed up a ton 'o space. Thanks!

Hello, I just want to share a tad of experience I gathered today with this issue, which might hopefully help some people here to understand what might be going on. We used a docker server for continuously deploying new software commits to a testing environment. After some time I found that around …

Hi, Just joining to add something to this discussion. I had this similarly problem with my servers. I had like 10 apps running with two containers each. Even with all of their volumes and data, I should have only 30-35GB of used storage, but instead, I was disk full at 155GB. What I did to solve t…

Thanks, I can confirm that the solution of deleting the logs files works: #to remove all log files find /var/lib/docker/containers/ -type f -name “*.log” -delete Do not forget to restart the docker containers: docker-compose down && docker-compose up -d or Reboot the server to complete the clea…

[50] Worked like a charm for me! Thank u! :vulcan_salute::love_you_gesture:

to identify what overlay belongs to what image, container you may use: https://gist.github.com/epcim/cbe1e51b1f8ae011d84ce7a754401398

I can confirm that in my case docker system prune --all --volumes --force fixed the problem. Running the interactive docker system prune didn’t help. Either the force flag was needed or the --volumes (not sure which).

Thanks I’ll add that to the clean up list and see what happens. It’d still be nice to be able to map stuff from the overlay dir to what “owns” it though. This is a handy little one-liner I came up with to identify which image(s) own a particular folder in the overlay2 directory: for I in $(docke…

Actualy you can get all the details from docker inspect. This oneliner lists the mapping of overlay2 folders to exact RepoDigest information (this helps to distinguish folders even for mutable tags like “latest”) docker image inspect $(docker image ls -q) --format '{{ .GraphDriver.Data.MergedDir}…
