Ultraman start example

If no additional parameters are passed, ultraman will run one instance of each type of process defined in your Procfile.

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
-t --timeout 5 Specify the amount of time (in seconds) processes have to shutdown gracefully before receiving a SIGTERM
-n --no-timestamp false Include timestamp in output

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"
