Share and learn in the Docker community.
I have a 60gb Ubuntu VM setup for running docker + all my containers. But, I keep running into the problem that the overlay2 folder is growing exponentially and causing my VM to crash.
This is the ncdu -x of my docker folder, only 16gb filled.
I have tried clearing all stale volumes/containers/etc with sudo docker system prune -a --volumes --force but it doesnt free up any space.
How can I monitor during the containers to see which one is causing my VM to crash?
None of the folders on your screenshot belong to the overlay2 folder under the Docker data root. I say it only because you referred to it as âdocker folderâ, but you probably meant a folder where you store data for docker containers.
If pruning doesnât free up space, then it is probably not Docker that uses the generated data. Or there is a bug. I would run prune again and check the content of the overlay2 folder before starting anything.
Please, also show the output of docker info and docker version and remove anything from the output you would not want to share like IP addresses or username.
Small addition to @rimelekâs post: please also share the output of docker system df --verbose
Are you working with the VM through a console from which you cannot copy and paste the terminal output?
If you donât, please, use </> button to share codes, terminal outputs, error messages instead of sharing screenshots. That helps others to search for similar issues and us to read it more easily and quote parts of the message so we can help you more quickly. You can find a complete guide in the following post: How to format your forum posts
I am also confused as you wrote you ran docker system prune -a --volumes --force, but you ha a lot of images and other objects. Am I correct when I assume you ran system df after you also ran system prune as you quoted in your first post?
I understand docker system prune -a --volumes --force : it only prunes stopped containers or stale images, right?
But to answer your question - yes I ran system df after I ran docker system prune -a --volumes --force
Here is the output of the requested data:
root@docker:~# docker system df --verbose

Observations:
immich_machine_learning, nextcloud-app-1, and calibre-web. You might want to check using docker diff <container name> where you forgot to add a volume mapping into a container folder to store data outside the container.
Generally, with such a small base disk, you might want to consider using a dedicated block device for dockerâs data-root folder, to make sure that it will not render your system useless, when you manage to fill up the disk space of the dedicated block device.
I am pretty sure I didnât answer what you are looking for, but then again the original post didnât really specify something specific.
volumes: only 2 anonymous volumes, which indicates you are using bind mounts instead. Is it it safe to assume your first screenshot showed the disk usage of the host folders you bind mounted as volumes into the containers? â Yes correct, is that bad practice? I thought it was better to do it this way to allow for easy backups of the important folders.
This is the output of docker diff for immich folder, not sure what to make of this?

Even though you write folder, you must mean container.
The characters at the beginning of each line indicate A = add ; C = changed
Thus, the data in /root/.cache and /root/.config is written as new files into the container file system directly. This is data you loose, when you remove the container (like it happens when you use a new image tag).
I donât know the image, and canât tell you whether itâs safe to bind a host folder into the container /root folder, or if you need to bind two separate folders for /root/.cache and /root/.config. It depends whether data/files exists in /root required by the container to work. If /root is otherwise empty, a single bind should be enough to store the cache outside the container filesystem.
True. I missed that. For some reason I remembered wrong and thought it would remove everything. but I see the issue was solved, so thatâs great 
its still happening! I found one culprit container and removed it and that helped tremendously. But still happens every once in a while. How can I find out which container is causing overlay2 to grow just before the VM crashes due to no more space?
I am not sure what more we can say, but when you say âwhich container is causing overlay2 to growâ it means you have a container that writes to the container filesystem, so you can monitor the size of that. @meyay recommended using docker system df --verbose which shows that too, but you can also use docker container ls --size. Both command supports 'ââformat json` if you want to parse a json file to find the responsible container more easily.
how did you find the last container that you could remove to solve the porblem?
