Assumed the pluggin installation would do that.
That's a possible improvement for later. Jenkins has the concept of tools, and if I remember well, other plug-ins like Selenium Plugin fetch required dependencies. The trick part here is that some of these dependencies are OS specific, and could fail to be installed from Jenkins/JVM.
Easier to install via pip or conda.
Do you have steps to perform before issuing the pip install? Thank you.
All I did was to create a venv (python -m venv venv and activate it source ./venv/bin/activate). You could include these two steps in your container, though you would also either need to copy a layer with python/pip from another container, or modify your Dockerfile to fetch these two, plus run pip install -r requirements.txt or add the dependencies in another RUN command in your container.
