Beta doesn't work with --user to drop permissions

[jacobalberty]

Operating system

Debian Bullseye

UniFi Tag

beta

Docker run

docker run --rm --user unifi --init -e "PKGURL=https://dl.ui.com/unifi/6.5.55/unifi_sysvinit_all.deb" -p 8080:8080 -p 8443:8443 -p 3478:3478/udp -e TZ='Africa/Johannesburg' -v ~/unifi:/unifi --name unifi jacobalberty/unifi:beta

Bug description

It fails to start because beta tries to install unifi at launch time and it is not running as root.

I need to come up with a solution to safely run the install script as root. Perhaps through sudo or some other mechanism. Would need to perform some security auditing and cleanup on the install script too.

Steps to reproduce

Just run the docker run command line and look at the logs
