We are currently using adoptopenjdk/openjdk8.

This should probably use the new Universal Base Image, which can be used by both Red Hat customers and anyone else: https://www.redhat.com/en/blog/introducing-red-hat-universal-base-image

The original image linked in the description is only available to OpenShift customers, so we would have had to support two different base image options. Now we don't have to!

Unfortunately, they don't currently provide a base image with a JVM, but you can use the one that includes yum and use it to install the OpenJDK 8 package.
