how to deploy to heroku? about hedwig HOT 7 CLOSED

Heroku kills web apps if they don't respond to $PORT in 60 seconds. see: https://devcenter.heroku.com/articles/error-codes#r10-boot-timeout

I would just write a simple cowboy process that listens to and set to port to System.get_env('PORT') || 4000

This is all you need to add: https://github.com/joshrotenberg/elixir_cowboy_examples/tree/master/apps/hello_world

Just change the port.

That should work.

@meatherly thanks for the tips!
I know about the "web" process specificities, but it amazes me that heroku forces you to create a useless web process just to let other dynos live.

From what I read here https://devcenter.heroku.com/articles/run-non-web-java-processes-on-heroku it seems we could run whatever long-running process without any web process.

Thoughts?

@docteurklein is there a reason why you cannot use a worker process? I have an elixir chat bot running as a worker on heroku that has stayed alive for months now without a web process.

My Procfile:

worker: mix run --no-halt

This is not a hedwig app, but I cannot imagine that deploying to heroku would be much different.

@bbrock25 thanks for the feedback
I tried at first to define a worker process only, but didn't get it to work.
What does your Procfile look like, and how are you starting it?
I tried with

bot: mix run --no-halt

and then push to deploy.

EDIT: i just tried to run it with heroku scale bot=1 and it seems to work. Still not sure why it doesn't at git push.

You probably needed to turn the worker on before it would automatically deploy. I'd imagine that deploying with git push should be fine now.

@bbrock25 thanks!
I didn't notice you added your Procfile, sorry to ask again how it looked like.
Anyway, I guess I can close this issue now?
