  • 1.  UDP Override at run time

    Posted Tue November 30, 2021 07:03 AM
    Hello Team,

    Can anybody tell how to do the runtime UDP override in App Connect running in containerized environment. My problem is how to persistence the UDP values after each restart of the contianer.

    The UDPs will not persist across container restarts.  This is expected.  If you need this type of functionality, a UDP is probably not the best option.  You would need to configure the startup to read the value some from persistent location and then set it.  The problem is of course defining that readable persistent location within a container.  You could define a persistent volume and store a property file there.

    The better option is to replace the UDP with a different option, like an environment variable.

    Perhaps a User Defined Policy would fit the use case here? User defined policies can be deployed in a BAR file or provided to the container as an override in the working directory and will therefore be persisted across restart ... You could access them in the flow with Java.

    Thanks Ben Thomson for your reply,

    I will say my requirement.

    1.  I am storing the the provider system URL in one UDP variable.
    2. Suppose if I want change the URL I can update it via CURL command/Rest API.
    3. But in containerized environment , pod/container will restart some time.
    4. So the UDP value will not be persistent.
    5. How I can make the UDP value that I changed via CURL/Rest to be retained after container restart?
    In the above case, how I can achieve this using userdefined policy?

    Hi,

    We have stored our user-defined policies in a configmap in openshift. During startup of the container this configmap is referenced. So when a change is done to a user-defined policy we need to change the configmap and restart the container.

    Your suggestion is very good and works well.

    But they say here you can make the changes persistent. I'm testing it and it doesn't work. Have you ever tried it?

    Hi Pedro

    Have you set this inside your server.conf.yaml?

    UserVariables: 
  udp-persist-global-overrides: true

    You can supply a servers.conf.yaml override to your ACE container via a configuration resource. But I haven't tested it, can give it a try this week.

    Yes, I did that, but the values still did not persist. After restarting the integration server, the values returned to their default values.
