Is it possible to build and run a container image (that will run another container inside it) in the Jenkins job that is hosted on the openshift cluster?

I'm trying the $ISSUE_TITLE scenario and currently, I'm seeing some errors.

+ podman build --no-cache -f Dockerfile.tests --build-arg ACCEPTANCE_TESTS_URL=https://github.com/redhat-developer/helm-acceptance-testing --build-arg ACCEPTANCE_TESTS_COMMIT=helm-3.2-openshift -t helm-acceptacne-test /home/jenkins/workspace/helm-cpaas-run-acceptance-test

I tried few commands suggested in various issues

         0 1006860000          1

Is $ISSUE_TITLE even possible? If yes then could someone give me any pointers?
