Is it possible to add some explicit documentation on deploying the benchmark keycloak docker image? (or something like a link to the documentation like referencing 'build and new testing image and deploy from local using values file ###)

Do we need the java version installed to build the benchmark test runner that will be deployed in openshift? If so is it included in the keycloak repo's asdf tool version?

[NithinKuruba]

You would need Java 21 only if you are running the tests locally in your machine but when running in the Openshift, the docker image has the Java Runtime pre-installed
