Docker + Django + Angular + Heroku + Postgresql - Process exited with status 127, error code=H10 desc=“App crashed”

Question

I am trying to deploy on Heroku my project in Docker with Angular 4 frontend, Django backend and postgresql database. At this moment my files look as shown below. I am note sure if this is done properly? I pushed it using heroku container:push web --app myproject but it doesn't work (Logs). When I'm running docker-compose up without Heroku everything seems to be working properly.

I noticed that in logs there is Process exited with status 127 . I have found here 127 Return code from $? that

Value 127 is returned by /bin/sh when the given command is not found within your PATH system variable and it is not a built-in shell command. In other words, the system doesn't understand your command, because it doesn't know where to find the binary you're trying to call.

Besides, when I was trying different commands I very often were getting error like /bin/sh: 1 not found what I described in this post. Maybe it is a root of the problem? Or eventually there is a problem with ports like in this case?

Any other ideas? It seems to me that I was trying everything. I have no idea what is wrong.

I will be grateful if you could tell me if I am doing everything properly.

1.`heroku login`
2.`heroku container:login`
3.`heroku create nameofmyapp`
4.`heroku container:push web --app nameofmyapp`
5.`heroku open --app nameofmyapp`

I guess i'm running through the same issue, maybe you should only use docker-compose for running your application locally, and configure it to run on heroku using postgres add-on: https://devcenter.heroku.com/articles/heroku-postgresql .

But i'm unsure how to actually fire the application up after that. I can do the migrations using the django commands: python manage.py migrate, however cannot start the server on heroku using heroku run python manage.py runserver, because I'm uploading a Docker Image. So I'm unsure how to boot the application up. Maybe the add-on can help...

EDIT 1: Solved it for django apps, checkout my issue: Docker + Django + Postgres Add-on + Heroku
