For example, if you had an app that contained 1 web app listener and 1 background job processor, dokku can, spin up 1 container for each process type defined in the Procfile. By default, dokku will only start a single web process (if defined.) However, if you wanted, for example, 2 job processors running simultaneously, you can modify this behavior in one of the following ways.}  \tn
