# This script is a basic replacement for foreman when running on Docker. When
|

|
|
# starting the docker instance, specify as command `script/start <type>`.
|
||
|
|
# `type` is looked up in `Procfile` and the command is started. This allows e.g.
|
||
|
|
# docker-compose to run multiple process/dyno types from a single image, without
|
||
|
|
# needing to know the exact command (which may change over time).
