Running Unifi Controller in systemd-nspawn with cloud-init

This uses Ubuntu's server cloud image as a stateless container to run the UBNT Unifi Controller software. Configuration data is stored in a directory outside the container. Cloud-init is used to automatically set up the container image, so a new version can be dropped in with minimal effort. This should work with pretty much any modern Linux distro with systemd.

Setup

Systemd-nspawn prefers to store its machines on btrfs, so if your /var/lib/machines is not currently btrfs, you should create one and mount it there. Otherwise it will automatically create an image file at /var/lib/machines.raw and mount it.

Create a device

Pre-requests:

TFTP server
IPXE Make sure ipxe.lkrn is in the TFTP root.
iSCSI target (Server) Assume we have an iSCSI target "1:net.cszombie.au:windows" that is ready to be connected. 1 is LUN id, "net.cszombie.au:windows" is the target name.
HTTP server (To speed up loading boot.wim, http is faster than tftp, http is supported by IPXE, however this is optional)

1. Download wimboot to the root of the TFTP server

2. Create scripts:

centos8 @ OVH/SoYouStart/Kimsufi

How to install CentOS 8 on OVH/SoYouStart/Kimsufi

connect to the OVH/SoYouStart/Kimsufi API and create a ipxe script under https://eu.api.kimsufi.com/console/#/me/ipxeScript#POST or equivalent, see centos8.ipxe below
boot your server from this netboot, and ping it to follow the process. If you can observe the webserver's logs you will se your server's IP pulling kernel and initrd with "iPXE" user agent, then it will start pinging, and retrieve the kickstart.cfg a bit later (with "curl" user agent). This is the moment when you could set your server back to "Boot from Hard Disk".
Also at this point you can connect to your server with SSH using the key/password set in the kickstart file. type tmux a to attach the install's tmux session and follow the progress. For debugging, check the logs in /tmp and those sent over syslog.
