Answer 1

Have you tried scaling one of your process types? e.g. heroku ps:scale web=1

Or rather, check what's your current web count by using 'heroku ps' See https://devcenter.heroku.com/articles/scaling

Answer 2

I kept running into the same problem. The sample python application ran fine, but mine did not. I logged into the dashboard and noticed that the web dyno count for my app showed zero. So I bumped it up on the web gui (i.e., strech the slider widget until you get a non-zero count.) and that worked. My dashboard also showed the heroku ps:scale web=1 dyno at zero, and I left it as zero.

Answer 3

If you are using a container to build a web application, create a heroku.yaml file like this in your project's root:

build:
docker:
    web: Dockerfile
run:
    web: [PUT YOUR CMD COMMAND IN DOCKERFILE HERE]

Then add heroku.yaml to git repository. You can remove Procfile (optional). Finally deploy your repository as the following:

git add .
git commit -m "Add heroku.yml"
heroku stack:set container -a [YOUR APP NAME]
git push heroku master

If your are pushing to heroku for the first time, you should run heroku git:remote -a [YOUR APP NAME] before git push heroku master
