For the longest time I thought the standard was to install stuff on Docker as root and not worry about typical permission/user idioms you'd practice on a classic box.
But now I am seeing more of this. Do you have any good links to read more about why using venv/non-root makes sense for Docker?
In my case, I think Docker voids the need for virtualenv. But a quick google search returns interesting results [1]
I do know setting up a proper user in Docker is just a couple lines away in a Dockerfile (As a matter of fact, I did that for the main app I develop).
For my other use cases, I just don't care. I'm using Docker to quickly bootstrap a Jupyter Labs environment, and I do that by sharing some confs (Like the Pip cache folder).
The caveat to this is that files I create are owned by root, but that again is just a command away for fixing (If I need it, that haven't yet).
