        port: 8080
        protocol: TCP
        targetPort: 8080
    selector:
      app: tomcat

Open terminal in the newly created pod in requester container.
Try to access tomcat via service. Execute curl tomcat:8080 Expected: Response HELLO Actual: Request hung up.

Note that it works fine on https://console.codenvy.openshift.com/ or http://console.starter-us-east-2.openshift.com/. Note that it works fine if containers are in separated pods.

Should we perhaps close the issue as it cannot be fixed on Che side. The issue has been opened for a while and the issue in Origin does not seem to get any attention either.
