To debug or run a containerized native COBOL application running under Kubernetes

The topic To debug or run a containerized native COBOL application running on Enterprise Server describes the process for debugging or running a containerized native COBOL application running on Enterprise Server. This topic describes additional steps you need to perform if the container is running under Kubernetes.

1. Ensure that the kubectl command is available for you to use and configured to connect to your cluster.

   See Kubernetes: Install and Set Up kubectl for information.

2. Establish which pod you want to debug. You can use a command such as the following to do this:

   kubectl get pods

   See Kubernetes: Overview of kubectl for information.

3. Once the container has started and the region is running, make the following changes on the General tab of your launch configuration:
   • Select Kubernetes pod.
   • Select the required pod from the adjacent drop-down list.
   • Specify the local end of the port-forward in Endpoint port.
4. In the securityContext: field of the pod's specification, enable PTRACE as shown below:

     securityContext:
       capabilities:
         add:
         - SYS_PTRACE
