i think you should be fine to just run python3 -m ~/path/to/your/project/venv
this will make a venv folder in your project directory. whenever you want to work on your project you just do source ~/path/to/your/project/venv/bin/activate
and then pip install whatever
to install whatever packages you want in the venv. i don't think the fact that it's in a container should be any issue.
