Support for scaling processes #85

Closed ktchernov closed 4 years ago

ktchernov commented 4 years ago

It would be great to be able to scale a single Procfile line to run as multiple processes.

For example Procfile:

worker: /usr/local/bin/command.sh

But to be able to tell overmind to launch N number of these.

In Heroku this can be done with a ps:scale N command. In supervisord, there is a way to specify numprocs parameter per program definition.

If you look at the output of overmind s -h you will find this option

   --formation value, -m value     Specify the number of each process type to run. The value passed in should be in the format process=num,process=num. Use 'all' as a process name to set value for all processes [$OVERMIND_FORMATION]

Would be good to have this mentioned in the README

Added formation docs to README https://github.com/DarthSim/overmind#scaling-processes-formation
