Docker Container in Cics

After the last CAF I have thaught a while about running multiple images/Platforms in a Cics Region.

Now I think the only good solution for this, also what would bring multiple value to cics would be, to be able to run docker images in cics.

And with docker images I mean real docker images, not cicspt

This would give cics the possibility to be a container for everything.

    We have assessed this requirement. We have no current plans for this to be implemented and so this requirement is being declined at this point.

    No, this PMR should not address point 1 to 3.

    For number 4 I would say this is a part of it, as you need some sort of standard spezification everwhere works with.

    The more I am thinking what is important for the cics runtime I think it is the ability to just take ANY application from an linux or windows environment and just drop it to cics(without code changes) to make the application available there.

    Why?

    1) Reason 1: The main reason is portability -> like java program it once run it everywhere.

    What could I do with this?

    A programmer could create an application run it in his local docker image and then take this docker image and deploy it to cics. Of cource you would somehow need some cics resources for this, but this could be automated.

    The important part here would be that he could take what he build locally and tested locally and run it 1:1 in cics.

    The problem in cics

    2) Reason 2: Integrate customized Java Servers in Cics

    At the moment it is really painful and not possible to just take a developpers server.xml and put it to cics. Sysprogs have to do something to make this work and this is not good. I have not looked deeper into the open container initiative, but this is maybe a way to solve this problem.

    3) Reason 3: Getting new workload to cics

    There are a lot of docker based applications on linux out there, if it is easy to just take them and move them to cics customers would have the ability to go to the mainframe with all their apps. At the moment they must run this stuff in Linux or windows.

    4) Reason 4: If I look to cics I see more and more the counterpart of red hats openshift. A possibility of providing a very dynamic "virualisation" of a runtime inside an operating system for any language / container format in the market.

    Let me know if you need more information.

    Thanks PEter

    Do you require one or more of the following:
    1. The ability to provision multiple new LIberty JVM servers in an existing CICS region like RFE 83803 "more than one Liberty server per CICS region - using authorised services via Angel"
    2. z/OSMF workflows or a cloud provisioning template for 1
    3. Include an application in a z/OS PT image (with the current limitations one which resources are supported
    4. Support for Docker/OCI image format

    Actually running "a region in a region" would be a considerable and very unlikely investment based on the extensive private resource research we have done.

    Hey guys! I see the RFE Needs more Information. But I don't find anything on what kind of information you need. Please let me know.
