When using the CF plugin, we have a serious issue to use our command line in our manifest. The system complaint about not recognizing the $PORT. If we remove it, the deployment is passing from a perspective of delivering but the app is not started as CF do not recognize the default port 3000 (this is what is happening if we are not indicating the $PORT which is set by CF when deploying normally).

Is there a way to workaround this in Jenkins?

Here is the command in the manifest.yml we are using to start our app:

command: bundle exec rails s Puma -p $PORT -e production

Thank you
