Deploying to heroku?

[cheeyeo]

Hi

I have just created a phoenix app to test if it can be deployed to heroku.

I am following the instructions from https://github.com/sapporo-beam/phoenix-heroku and have tried to test locally by installing the dependency using

MIX_ENV=prod mix deps.get

Yet when I deploy to heroku it seems to grab all the dependencies but suddenly fails with

** (Mix) Could not start application ranch: could not find application file: ranch.app

@cheeyeo Please show the output from the heroku deploy/compile. What Elixir version are you using?

[cheeyeo]

@ericmj I'm using elixir version 0.15.0. Please find the output below:

I have logged into the heroku remote server and checked the _build/prod/lib directory and the ranch directory is not there which is causing it to fail?

any help is most appreciated

thanks

Can you pull the latest phoenix master and retry? The mix.lock contained an incorrect ranch dep, but it was fixed late yesterday after 0.15.0 support was added.

[ericmj]

There seems to be other strange things going on with all "module redefined" warnings.

[chrismccord]

I just successfully deployed the phoenix_chat_example app to Heroku (phoenix master, elixir 0.15.0). I'm using HashNuke's buidpack as well. Can you take a look at the example app and see if there's something you're missing? https://github.com/chrismccord/phoenix_chat_example

[cheeyeo]

hi @chrismccord I will try it out :+1: thanks again for your help

[cheeyeo]

hi @chrismccord I managed to get it to work by following your setup in your example application posted above. Thanks again for your help :+1: :+1:

[jeregrine]

@chrismccord might be a good thing to add to the wiki? "Deploying to heroku" or even a blog post I suppose.

[josevalim]

I don't like wikis because they get horrible outdated and unless you have someone actively taking care of it, it becomes a mess very quickly. For Dynamo, we had a bunch of howto/guides in the repository. You could consider something similar here, be it in this repo or in another one. For now, since there is still a lot of code churn, doing in the same repo sounds like a good idea.

[josevalim]

https://github.com/dynamo/dynamo/tree/master/guides

[jeregrine]

The guides can get just as outdated. :trollface: but yea I understand I have no opinion on where it goes.

[josevalim]

Guides are easier to be updated on the repo because when you do backwards incompatible changes it is easier to grep. Another advantage of guides is that we would receive PRs for changing them, instead of free access like in the wiki, so we can guarantee quality. The idea though is to have dozens of guides covering the most important bits.
