  • 1.  WebSphere Liberty Official Docker Image Java 21 Support

    Hi,

    I am trying to explore the websphere-liberty official docker image and I see the image tags to be only supporting Java 17. Will there a future release to include Java 21?

    Also, on the other hand, I am looking at this docker image repo, https://hub.docker.com/r/ibmcom/websphere-liberty. This repo has Support for Java 21. I see this repo is maintained by IBM, what's the difference between the official docker image vs the image that's available in this repo?

    Thanks,

    Rohit

    Hi,

    If you are comparing these two:

    • https://hub.docker.com/_/websphere-liberty

    • https://hub.docker.com/r/ibmcom/websphere-liberty

    The difference is underlying operating system:

    • First one uses - WebSphere Liberty multi-architecture images based on Ubuntu 18.04
    • Second - WebSphere Liberty multi-architecture images based on UBI 8.

    The UBI is preferred for OpenShift deployments, but you should be able to use it in any other container environment also.

    Thank you for the Response.

    Follow up question on this docker image, https://hub.docker.com/_/websphere-liberty. Would there be a Java 21 version available soon for this ubuntu image? Just Curious.

    Thank you.

    I spoke with the folks that are maintain the container images.  They recommend using the IBM Container Registry if you want to use Java 21 with Liberty in a container.  There is no date for the release on Ubuntu with Java 21.

    You can also use the IBM Container Registry to get the images.  More info in the Knowledge Center.
