How to: Building a headless container to run remotely with secure VNC
Add the following line:

`-e EXTRA="-display none -vnc 0.0.0.0:99,password=on"`

In the Docker terminal, press `enter` until you see `(qemu)`.

Type `change vnc password someusername`

Enter a password for your new vnc username^.

You also need the container IP: `docker inspect
| jq -r '.[0].NetworkSettings.IPAddress'`

Or `ip n` will usually show the container IP first.

Now VNC connects using the Docker container IP, for example `172.17.0.2:5999`

Remote VNC over SSH: `ssh -N root@1.1.1.1 -L  5999:172.17.0.2:5999`, where `1.1.1.1` is your remote server IP and `172.17.0.2` is your LAN container IP.

Now you can direct connect VNC to any container built with this command!
