I cannot seem to install gcc-9 or libstdc++6 for ubi8-miniman distro.
error: No package matches 'gcc-9'
I know there is a enablerepo= which I can use to point towards the repo for packages that are not inside the minimal one, but the repos I tried so far were not correct.
Maybe somebody had a similar challenge and solved it?
The minimal base image also only comes with a minimal package manager. As you can read in RH's blog post on this the minimal image has the following:
Minimal - Designed for applications that contain their own dependencies (Python, Node.js, .NET, etc.)
Minimized pre-installed content set
No suid binaries
Minimal package manager (install, update, and remove)
So you can only install what's available more or less. You can enable and disable repos but only from the following list:
# microdnf repolist

(microdnf:155): librhsm-WARNING **: 07:08:39.301: Found 0 entitlement certificates
repo id repo name
ubi-8-appstream-rpms Red Hat Universal Base Image 8 (RPMs) - AppStream
ubi-8-baseos-rpms Red Hat Universal Base Image 8 (RPMs) - BaseOS
ubi-8-codeready-builder-rpms Red Hat Universal Base Image 8 (RPMs) - CodeReady Builder
You can look up all packages available for those here but there will only be gcc in version 8.5 available.
