Error with DATABASE_URL when deploying Phoenix application to Heroku
Hi, I’m following phoenix/guides/deployment/heroku.md at main · phoenixframework/phoenix · GitHub to deploy using Heroku containers.
Here’s the example repo: GitHub - biske/hello: Basic Phoenix application to test deployment to Heroku · GitHub
When I push to heroku I get following error:
Apples-MacBook-Pro:hello ivanbisevac$ git push heroku master

Have you set up database on your Heroku app? ‘DATABASE_URL is missing’ means that you haven’t exported the environment variable. You probably didn’t add a database as addon on Heroku.
If you use postgres, here is the tutorial how to do it: Heroku Postgres | Heroku Dev Center

That’s ok, but my question is not about buildpack deploy, but container one. Whole point is that there is Phoenix documentation how to deploy which doesn’t work.
