I am running a docker container (used by me and me only) on a shared ssh server. Recently, I needed to install a new package through pip, and noticed the following warning:
WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead
Now: I don't care about the container itself since it gets destroyed once I'm done with it anyway (I use docker run (...) --rm), but I'm concerned about the host machine. As far as I know, containers are supposed to be 100% isolated, meaning that in case of any "conflicting behaviour with the system package manager", they will affect at most the container's and not the host's. Correct? Does that mean that I can safely ignore the message? Anything else I should be mindful of with respect to the host machine?
Sorry for the stupid question, but I am a docker noob. Many thanks in advance.
