not able to access Django project through Docker Compose - python

I have created a simple Docker file for DJango project and when I issue docker run, I am able to access through browser.
docker run -p 8000:8000 s3bucket-ms:1
Here is the Docker File:
FROM python:3.6.7-alpine
ENV PYTHONUNBUFFERED 1
COPY ./requirements.txt /requirements.txt
RUN pip install --upgrade pip
RUN apk update \
&& apk add postgresql-dev gcc python3-dev musl-dev
RUN pip install -r requirements.txt
RUN mkdir /app
WORKDIR /app
ADD ./s3bucket /app/
EXPOSE 8000
CMD ["python", "./manage.py", "runserver", "0.0.0.0:8000"]
However, when I am using Docker Compose , i can't access the project through the browser.
Here is the docker-compose.yml
version: '3'
services:
web:
build: .
command: python ./manage.py runserver 8000
ports:
- "8000:8000"
With Docker Compose , I also commented CMD within Docker File.
Output from Docker Compose UP
web_1 | Run 'python manage.py migrate' to apply them.
web_1 | February 17, 2020 - 14:29:22
web_1 | Django version 3.0.3, using settings 's3bucket.settings'
web_1 | Starting development server at http://127.0.0.1:8000/
web_1 | Quit the server with CONTROL-C.
Am I missing something? Any help is appreciated.
Thanks,

Add EXPOSE 8000 on your Dockerfile
Update1:
With docker run
docker run \
-v /path/to/s3bucket:/app \ # absolute path
-p 8000:8000 \
s3bucket-ms:1
With docker-compose
version: '3'
services:
web:
build: .
command: python ./manage.py runserver 8000
volumes:
- /path/to/s3bucket:/app # absolute path
ports:
- "8000:8000"

Trying to run a container on docker but can not access the website of the application we created

We've been using python3 and Docker as our framework. Our main issue is that while we try to run the docker container it redirects us to the browser but the website can not be reached. But it is working when we run the commands python manage.py runserver manualy from the terminal of VS code
here is the docker-compose.yml file
version: "2.12.2"
services:
web:
tty: true
build:
dockerfile: Dockerfile
context: .
command: bash -c "cd happy_traveller && python manage.py runserver 0.0.0.0:8000 "
ports:
\- 8000:8000
restart: always
the docker file
FROM python:3.10
EXPOSE 8000
WORKDIR /
COPY happy_traveller .
COPY requirements.txt .
RUN pip install -r requirements.txt
COPY . .
and the app structure
|_App_Folder
|_happy_traveller
|_API
|_paycache
|_core
|_settings
|_templates
|_folder
|_folder
|_folder
|_manage.py
|_dockerfile
|_docker-compose.yml
|_requirements.txt
|_readmme.md
|_get-pip.py
We would really apreciate the help. thank you for your time
As you copied the source folder(happy_traveller) in your docker file, you don't need to run the cd command again, so the docker-compose file would look like this:
version: "2.12.2"
services:
web:
tty: true
build:
dockerfile: Dockerfile
context: .
command: bash -c "python manage.py runserver 0.0.0.0:8000 "
ports:
- 8000:8000
restart: always

Can't open localhost in the browser on port given in docker-compose

I am trying to build and run django application with docker and docker-compose.
docker-compose build example_app and docker-compose run example_app run without errors, but when I go to http://127.0.0.1:8000/ page doesn't open, I'm just getting "page is unavailable" error in the browser.
Here is my Dockeffile, docker-compose.yml and project structure
Dockerfile

COPY ./requirements.txt /app/requirements.txt
COPY ./requirements_dev.txt /app/requirements_dev.txt
RUN pip install --upgrade pip

docker-compose.yml
version: '3'
services:
example_app:

build:

dockerfile: ./docker/Dockerfile
command: bash -c "cd app_examples/drf_example && python manage.py runserver"

By default, Django apps bind to 127.0.0.1 meaning that they'll only accept connections from the local machine. In a container context, the local machine is the container, so your app won't accept connections from outside the container.
To get it to accept connections from anywhere, you add the bind address to the runserver command. In your case, you'd change the command in your docker-compose.yml file to
command: bash -c "cd app_examples/drf_example && python manage.py runserver 0.0.0.0:8000"
you need to expose port 8000 in your Docker file
FROM python:3.9-buster
EXPOSE 8000
RUN mkdir app
WORKDIR /app
COPY ./requirements.txt /app/requirements.txt
COPY ./requirements_dev.txt /app/requirements_dev.txt
RUN pip install --upgrade pip
RUN pip install -r /app/requirements.txt

Unable to create a container for a Django app

I was trying to make a basic container as a learning project that should download Django from PyPI and run the default server. For that I made 3 files i.e.
docker-compose.yml
version: '3'
services:
web:
build: .
command: python manage.py runserver 0.0.0.0:8000
volumes:
- .:/app
ports:
- "8000:8000"
Dockerfile
FROM python:3
ENV PYTHONUNBUFFERED 1
RUN mkdir /app
WORKDIR /app
COPY /requirements.txt /app/
RUN pip install -r requirements.txt
COPY . /app/
requirements.txt
Django==4.0
the command that I used in terminal and the output are given below in the terminal snippet:
samar#wasseypur:~/Desktop/project2/telusko$ sudo docker-compose run web django-admin startproject mysite .
[sudo] password for samar:
Creating telusko_web_run ... done
Error response from daemon: OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "django-admin": executable file not found in $PATH: unknown

Django not running from Docker image, cant access

My Dockerfile is:
FROM python:3.5
RUN apt-get update
USER root
WORKDIR /app
ADD . /app
RUN pip install -r requirements.txt
WORKDIR /app/etalentNET
EXPOSE 8000
CMD ["python", "manage.py", "makemigrations"]
CMD ["python", "manage.py", "migrate"]
CMD ["python", "manage.py", "runserver", "0.0.0.0:8000"]
My docker-compose.yaml is:
version: '3'
services:
db:
image: sqlite3
web:
build:
image: demo:latest
dockerfile: Dockerfile
command: python3 manage.py runserver 0.0.0.0:8000
volumes:
- .:/code
ports:
- "8000:8000"
depends_on:
- db
When I run docker run -p 8000:8000 demo it doesn't do anything.
CONTAINER ID IMAGE COMMAND CREATED STATUS
4829d420c560 demo "python manage.py ru…" 9 minutes ago Exited (0)
But when I run docker run -p 8000:8000 -it demo bash and then there python manage.py runserver 0.0.0.0:8000 the servers start running (but can't access it via <host_ip>:8000. I don't know why).
I'm running in a Google Cloud Compute Engine virtual machine with Ubuntu 16.04, and Django-2.0.6.
Put allowed_hosts='*' in settings.py

Django with Docker - Server not starting

I have followed the steps in the official docker tutorial for getting up and running with django: https://docs.docker.com/compose/django/
It works fine until I have to run docker-compose up
It doesn't directly give me an error, but it won't run the server either, stopping at this point:
(Screenshot of the Docker Quickstart Terminal)
docker-compose.yml:
version: '3'
services:
db:
image: postgres
web:
build: .
command: >
bash -c
"python3 manage.py migrate
python3 manage.py runserver 0.0.0.0:8000"
volumes:
- .:/code
ports:
- "8000:8000"
depends_on:
- db
Dockerfile:
FROM python:3
ENV PYTHONUNBUFFERED 1
RUN mkdir /code
WORKDIR /code
ADD requirements.txt /code/
RUN pip install -r requirements.txt
ADD . /code/
I am on Windows and have therefore used docker-toolbox.
Thanks for your suggestions!
Start docker-compose in detached mode:
docker-compose up -d
check your django container id
docker ps
then log into container:
docker exec -it yourDjangoContainerID bash
then go to directory where manage.py file is, and type
python manage.py migrate
You can put the migration command into your docker-compose.yml file. Something like
web:
command: >
bash -c
"python3 manage.py migrate
python3 manage.py runserver 0.0.0.0:8000"
replacing
web:
command: python3 manage.py runserver 0.0.0.0:8000
This will apply migrations every time you do docker-compose up.
