I run a docker image with a bind-mount pointing to a non-existing host directory. The docker image then created data into that volume, wherever it may be. The data is accessible on every docker run.
If I then create that missing host directory and re-run the container, the new host folder is used, creating new data. When I remove it again, the old data shows up again.
I have done
docker volume prune and have nothing coming up with
docker volume ls.
When I remove the host directory again, then also remove the container and the image, then re-run the docker container, I can see the image getting re-downloaded, but then the old data is still there.
How do I identify the location of the old data and interact with it?
