Document OpenJDK images on OpenShift

XMLWordPrintable

      We've had requests where various provided OpenJDK image streams from a default OCP installation can cause confusion. Image streams to pick from are (but might not be limited to):

       

      From the assets, I was able to extract some information about the different Java version available in:
      
      OCP 4.5
      java-rhel7.json =>  java:8, java:11, java:latest
      openjdk-11-rhel7-rhel7.json => openjdk-11-rhel7:1.0, openjdk-11-rhel7:1.1
      openjdk-11-rhel8-rhel7.json => openjdk-11-rhel8:1.0
      openjdk-8-rhel8-rhel7.json => openjdk-8-rhel8:1.0, openjdk-8-rhel8:1.1, openjdk-8-rhel8:1.2
      redhat-openjdk18-openshift-rhel7.json => redhat-openjdk18-openshift:1.0, redhat-openjdk18-openshift:1.1, redhat-openjdk18-openshift:1.2, redhat-openjdk18-openshift:1.3, redhat-openjdk18-openshift:1.4, redhat-openjdk18-openshift:1.5, redhat-openjdk18-openshift:1.6, redhat-openjdk18-openshift:1.7, redhat-openjdk18-openshift:1.8
      
      OCP 4.6
      java-rhel7.json => java:8, java:11, java:latest
      openjdk-11-rhel7-rhel7.json => openjdk-11-rhel7:1.0, openjdk-11-rhel7:1.1
      openjdk-11-rhel8-rhel7.json => openjdk-11-rhel8:1.0
      redhat-openjdk18-openshift-rhel7.json => redhat-openjdk18-openshift:1.0, redhat-openjdk18-openshift:1.1, redhat-openjdk18-openshift:1.2, redhat-openjdk18-openshift:1.3, redhat-openjdk18-openshift:1.4, redhat-openjdk18-openshift:1.5, redhat-openjdk18-openshift:1.6, redhat-openjdk18-openshift:1.7, redhat-openjdk18-openshift:1.8
      ubi8-openjdk-11-rhel7.json => ubi8-openjdk-11:1.3
      ubi8-openjdk-8-rhel7.json => ubi8-openjdk-8: 1.3, java:8

       

      Basically this boils down to:

      • explaining when to use specific tags
      • explaining how image streams map to OpenJDK images in the RH container catalogue
