The Unifi Network controller runs a syslog server (listening on UDP port
5514) where Unifi devices can send their logs. We need to open the port
in the firewall in order for it to receive log messages and write them
to disk.
The _linuxserver.io_ image for UniFi Network is deprecated. It sucked
anyway. I've created a simple image based on Debian that installs the
_unifi_ package from the upstream apt repository. This image doesn't
require running anything as _root_, so it doesn't need a user namespace.
The UniFi controller service can sometimes take a really long time to
start up. This most frequently happens after a full outage, when the VM
hosts are very busy bringing everything up.
Since Ubiquiti only publishes Debian packages for the Unifi Network
controller software, running it on Fedora has historically been neigh
impossible. Fortunately, a modern solution is available: containers.
The *linuxserver.io* project publishes a container image for the
controller software, making it fairly easy to deploy on any host with an
OCI runtime. I briefly considered creating my own image, since theirs
must be run as root, but I decided the maintenance burden would not be
worth it. Using Podman's user namespace functionality, I was able to
work around this requirement anyway.
