Permission issue in docker run

[nitisht]

I've tried using /tmp as in the previous rendition of the docs, but after getting the error, I modified the permissions of /tmp/parseable to a+rw, then it works.
After storing some data, this is what has been created when listing from the host system

total 0
drwxr-xr-x 3 65532 65532 60 maj  1 19:14 'date=2023-05-01'

Basically everything is stored under an arbitrary UID (65532), which in general doesn't translate well to mapping in directory volumes from the host. I think the containers should be updated to simply use root (probably not the best practice for other reasons...), or start with root to set up the correct permissions, and then drop privileges, or simply document how to use Docker volume containers.
