[CIAM-2881] Add a demo on how to rebuild the standard Red Hat Single Sign-On
7.5 container image to start using the latest version of IBM Semeru 11 Open
Edition JDK (OpenJ9 JVM) instead of the default Red Hat OpenJDK 11 one.

Also add a helper script to (re)generate the existing templates to start
using the newly built image stream

@dale-fu @levicic PTAL once got a chance (I have tested the changes on single s390x / ppc64le hosts too, and they seems to WFM correctly there too AFAICT, but better to verify them on full OpenShift cluster on these architectures too)

@andymunro PTAL at / review the associated README.md once got a chance. If there's something that should be updated, kindly let me know

Thanks to all of you for your time in advance!

@dale-fu @levicic JFTR, obviously, till the PR is merged, you will need to change the last line in the above command to point to my fork & corresponding branch instead of the form above. IOW, create new build as follows:

$ oc new-build \
     --context-dir=jdk/ibm-semeru-open-11-jdk \
     --image-stream=sso75-openshift-rhel8 \
     --name=sso75-openshift-rhel8-ibm-semeru-11-jdk \
     --namespace=openshift \
     --strategy=docker \
     https://github.com/iankko/redhat-sso-7-openshift-image.git#semeru

The rest of the proposed steps should work without additional changes AFAICT.

Fixed in latest version. Thanks for pointing out!

.Prerequisites

@andymunro I will actually need to revert these changes back. The code isn't written in Asciidoc, but rather in Markdown syntax, so the dot before the string actually does nothing. See here, on how it's rendered:

• https://github.com/iankko/redhat-sso-7-openshift-image/tree/semeru/jdk

Instead of Prerequisites, it's just '.Prerequisites' (IOW without any effects).

The same case for the other remaining strings, that were modified. Are you OK with returning the previous form?

Thanks, Jan

[andymunro]

A few changes, @iankko. Thanks.

[iankko]

A few changes, @iankko. Thanks.

@andymunro Fixed all of them, as suggested. Thanks!

[andymunro]

Yes, of course; please change it back. Thanks for asking @iankko .
