Minimize the RPM content of the Quarkus container
Even though we use `ubi8-minimal` as the parent of our container, it
still has many RPMs installed that aren't necessary to run the Keycloak
server. Also, since the JDK RPM (that we install on top of
`ubi8-minimal`) is designed for general use, it pulls in more dependency
RPMs than it strictly needs to, like cups and avahi. Keycloak will never
need to access a printer itself!
Trimming down these excess RPMs will improve our CVE statistics with
automated scanners, and therefore let us perform fewer CVE rebuilds.
`ubi8-null.sh` uses the low-level `rpm` command to identify and forcibly
remove dependencies and operating system files that are not required to
boot our Quarkus-based server. This includes `microdnf` and `rpm`
itself! I have preserved bash however, so it's still possible to debug
the container from a shell.
I've created an initial set of allow/disallow lists, that seems to pass
a smoke test (server boots, admin console works). This leaves 37
packages installed, with 96 removed relative to `ubi8-minimal`. We could
go more minimal than this, or less minimal if required. Trial and error
is required.
