Even though Mongo says it doesn't support WSL, you can still make it work. Just install MongoDB as you would any regular Ubuntu system
If you tried to start it with systemctl start mongod, it will fail with an error like:
System has not been booted with systemd as init system (PID 1). Can't operate.
Well...if SystemD doesn't work, then use SystemV!
Create an /etc/init.d/mongod with the script below (don't forget to chmod +x it afterwards), and then simply start the service using service mongod start:
#!/bin/sh
#
# init.d script with LSB support.

# Short-Description: An object/document-oriented database
# Description: MongoDB is a high-performance, open source, schema-free
# document-oriented data store that's easy to deploy, manage
# and use. It's network accessible, written in C++ and offers
# the following features:
#
# * Collection oriented storage - easy storage of object-
# style data
# * Full index support, including on inner objects
# * Query profiling
# * Replication and fail-over support
# * Efficient storage of binary data including large
# objects (e.g. videos)
# * Automatic partitioning for cloud-level scalability
#
# High performance, scalability, and reasonable depth of
# functionality are the goals for the project.
