Ubuntu LXC/LXD Configuration Help

I am in need of someone to document how to configure and set up an LXC/LXD environment on a freshly installed Ubuntu 22.04 server. This is for a POC and you will not have direct access to the test environment, but will work with me to resolve any issues and update the documentation. I am looking for the following configurations 1: A container with an external ip 2: A container on a private network shared by multiple containers 3: A container with two interfaces. One external and one on the network from item #2 This will be a proxy instance, for nginx
