Docker-compose tutorial not working "python: can't open file 'manage.py"

Question

I am running simple Docker-compose example shown here

Here is Dockerfile:

 FROM python:2.7
 ENV PYTHONUNBUFFERED 1
 RUN mkdir /code
 WORKDIR /code
 ADD requirements.txt /code/
 RUN pip install -r requirements.txt
 ADD . /code/

Here is docker-compose.yml:

 version: '2'
 services:
   db:
     image: postgres
   web:
     build: .
     command: python manage.py runserver 0.0.0.0:8000
     volumes:
       - .:/code
     ports:
       - "8000:8000"
     depends_on:
       - db

When I am trying to launch the example with docker-compose it gives me following:

alex@universe:~/projects/testcompose$ docker-compose up
testcompose_db_1 is up-to-date
Recreating testcompose_web_1
Attaching to testcompose_db_1, testcompose_web_1
web_1  | python: can't open file 'manage.py': [Errno 2] No such file or directory

Probably tutorial is not up to date so if you know answer please write it here.

Right, project file structure was generated correctly. Django always has a my-project-folder/my-site/my-site file structure.

To make it work with docker-compose you just need to move up the following files to my-project-folder/my-site/

Dockerfile
docker-compose.yml
requirements.txt

my-project-folder/my-site/ already contains manage.py file (if that is not the case then something is wrong)

At this point make sure that my-project-folder/ only contains my-site/ folder and nothing else.

Once everything is setup correctly just move up to my-project-folder/my-site/my-site execute command docker-compose up it will build everything needed. execute command docker-compose up a second time and there you have it.

Dont forget to check allowed host and add '0.0.0.0' on settings.py file if needed.

that's all.
