Description of problem:

I am no longer able to deploy my Elixir/Phoenix app using Dokku on a DigitalOcean Linux droplet, as I get the following error every time.

Buildpacks:

https://github.com/HashNuke/heroku-buildpack-elixir.git
https://github.com/madshargreave/geo_buildpack.git

No Dockerfile or Procfile

I am not sure if related, but the problem seemed to occur around the time I added a docker-options--restart=always`, I tried removing it, but it does not help

Can you include all of the information we ask for in our issue template? It is helpful for debugging problems. Thanks.

Sorry about that, updated with as much info/outputs as I could

I'm guessing those buildpacks don't spit out a .release file that is usable by herokuish. I wonder, does this app works on Heroku?

The quickest probable fix is to define a Procfile with a web proc type that runs your app as expected. https://devcenter.heroku.com/articles/procfile

josegonzalez commented 8 years ago

When Heroku writes the .release file, it doesn't "merge" the .release files, and your last buildpack doesn't write a proper .release file. Since you don't have a Procfile, neither Dokku nor Heroku will run a command.

Here is the relevant logging output from Heroku:

remote: -----> Discovering process types
remote:        Procfile declares types -> (none)

Dokku/Herokuish just doesn't output that nothing was detected:

-----> Discovering process types

App confirmed not to work on Dokku or Heroku without the following Procfile:

web: mix run --no-halt

Closing as we're following what Heroku does here and it's clear that this is an app issue. If you reverse the order of the buildpacks, everything should start fine.
