Ultraman export example

ultraman export is used to export your application to another process management format.
A location to export can be passed as an argument. This argument may be either required or optional depending on the export format.

The following options control how the application is run:

short long default description
-m --formation all=1 Specify the number of each process type to run. The value passed in should be in the format process=num,process=num
-e --env .env Specify an environment file to load
-f --procfile Procfile Specify an alternate Procfile to load
-p --port Specify which port to use as the base for this application. Should be a multiple of 1000
-a --app Use this name rather than the application's root directory name as the name of the application when exporting
-l --log Specify the directory to place process logs in
-r --run Specify the pid file directory, defaults to /var/run/
-T --template Specify an template to use for creating export files
-u --user Specify the user the application should be run as. Defaults to the app name
-d --root Specify an alternate application root. This defaults to the directory containing the Procfile
-t --timeout 5 Specify the amount of time (in seconds) processes have to shutdown gracefully before receiving a SIGTERM

Example

Here is an example when the Procfile and .env files have the following contents

[Procfile]

exit_0: ./fixtures/exit_0.sh
exit_1: ./fixtures/exit_1.sh
loop: ./fixtures/loop.sh $MESSAGE

[.env]

MESSAGE="Hello World"
