installing mongodb using docker

Question

I am installing mongodb on linux mint (Tina) (Ubuntu 18.0.4) using Docker. I am unsure what version should I install. I see available tags here https://hub.docker.com/_/mongo/ Because my linux version is 18.04 Bionic, I guess I should use Mongo Bionic rather than Xenial However, I see the tag names as -

4.1.13-bionic, 4.1-bionic, unstable-bionic

Is it an unstable release ? What tag should I use in the following command ?

docker pull mongo:4.1.13-bionic or 4.1-bionic or something else

If I do not give a tag, I get Mongo 4.0.11 However I don't see any tag 4.0.11-bionic in the list. Is it pulling 4.0.11 Bionic or Xenial ?

What is simple tag vs shared tag ?

If an image does not have suffix Xenial or Bionic (e.g. 4.0.11) then is it valid for both Xenial (Ubuntu 16) and Bionic (Ubuntu 18 ) ?

TL;DR; You can pick any image. Not necessarily matching your host OS.

I guess ubuntu 18.04 is the host OS (the OS running the docker service). The image specified in dockerhub is the base docker image for the container and has nothing to do with your host OS.

It only matters if you want to extend the image and/or care about its size.
