Description Jonas Nordell 2020-07-28 08:01:23 UTC

Document URL: 

https://access.redhat.com/documentation/en-us/openshift_container_platform/3.11/html/using_images/other-images#configuration-and-customization

https://docs.openshift.com/container-platform/3.11/using_images/other_images/jenkins_slaves.html#environment-variables

Section Number and Name: 

Jenkins Agents - Configuration and Customization >> Environment variables

Describe the issue: 

With the introduction of OpenJDK 11 support in the 3.11 Maven 3.5 Jenkins Agent image, a new environment variable was introduced named "USE_JAVA_VERSION" [0]. This new variable is not found anywhere in the documentation.

https://github.com/openshift/jenkins/blob/openshift-3.11/slave-base/contrib/bin/run-jnlp-client#L24

Suggestions for improvement: 

The behavior and possible usage of this variable should be documented. At least mentioning that it exists and that it is possible to switch between java-1.8.0 and java-11 if necessary.
