How to run Django on Docker container

Question

I'm setting up a django server application on docker. docker runs the container well but the command to run django is not taking by docker.

I've already gone through few youtube videos but none of them worked for me

Dockerfile

FROM python:3.6-stretch

MAINTAINER ***

ENV PYTHONBUFFERED 1

COPY ./requirements.txt /requirements.txt

RUN pip install -r /requirements.txt

RUN mkdir /specfolder
WORKDIR /specfolder
COPY ./myfolder /specfolder

EXPOSE 8000

CMD ["python", "manage.py runserver"]

i've tried placing the command under docker-compose.yml file under

commands: sh -c "python manager.py runserver"

but none of them worked

docker-compose.yml file

version: "3"

services:
myapp:
    build:
        context: .
    ports:
        - "8000:8000"
    volumes:
        - ./myfolder:/specfolder

requriements.txt

django==2.2.4
pandas
xlrd
xlsxwriter

as of now under kinematics i am getting the python shell

Type "help", "copyright", "credits" or "license" for more information.

You need to make changes in your runserver command. Change it to

python manage.py runserver 0.0.0.0:8000

Your Dockerfile will be something like this

# other command
CMD ["python", "manage.py", "runserver", "0.0.0.0:8000"]

Make changes accordingly if you are using Dockerfile or docker-compose.

I see 2 problems in your implementation.

In Dockerfile you have, CMD ["python", "manage.py runserver"]. It should be CMD ["python", "manage.py", "runserver"]
In compose file commands: sh -c "python manager.py runserver" should be commands: python manager.py runserver.
1. a. If you use compose file then CMD should be removed from Dockerfile

Watching for file changes with StatReloader Performing system checks... System check identified no issues (0 silenced). You have 17 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, sessions. Run 'python manage.py migrate' to apply them.
