My problem is when I run my application on a container and map a port, the app does not run on my local machine.
I use ubuntu and here is my dockerfile:
FROM python:3.8.13-alpine3.14
WORKDIR /app/
COPY ./requirements.txt .
RUN apk add -u zlib-dev jpeg-dev gcc musl-dev
RUN python3 -m pip install --upgrade pip
RUN pip3 install -r requirements.txt
COPY . .
ENV API_URL='http://my_api.com'
EXPOSE 8000
CMD ["python", "manage.py", "runserver", "8000"]
when I run the image with the command bellow django app starts in the container.
docker run -d -p 8000:8000 dj-test
I say that because when I run a shell in this container
docker exec -it e906801932ac sh
and I check 127.0.0.1:8000, here is the response:
/app # wget localhost:8000
Connecting to localhost:8000 (127.0.0.1:8000)
saving to 'index.html'
index.html 100% |*****************************************************************************************************************************| 10697 0:00:00 ETA
'index.html' saved
but when I try this in my local machine, the response is different.
wget localhost:8000

when I try docker ps here is the response:

Can you help me to find the problem here? Thanks.
