Mongodb install steps inside LXD container on rpi4
#!/bin/sh
# MongoDB official community ed discontinued support of raspberry pi after mongod 4.4
# We tried their steps from https://www.mongodb.com/docs/v4.4/tutorial/install-mongodb-on-ubuntu/
# and the result is core dump; didn't matter for 20.04/18.04 images, all core dumps.
# Lesson learned, just use the old apt package provided by Ubuntu.
lxc launch ubuntu:20.04 mdb
lxc exec mdb -- bash
