'RUN pip install -r requirements.txt' not working

I am new to Docker and trying to deploy a django project with the same. But after building the docker-compose I am getting this error:

ERROR: Could not open requirements file: [Errno 2] No such file or directory: 'requirements.txt' ERROR: Service 'web' failed to build: The command '/bin/sh -c pip install -r requirements.txt' returned a non-zero code: 1

I might be messing up in setting the correct path so here is my project structure

~/Desktop/Projects/ToDoApp
   ToDoApp
     settings.py
   docker-compose.yml
   Dockerfile
   manage.py
   requirements.txt

Here is my dockerfile

#pull official base image
FROM python:3

#set envionment variables
ENV PYTHONUNBUFFERED 1

# Adding requirements file
ADD requirements.txt ToDoApp/ToDoApp

#set work directory
WORKDIR /ToDoApp

#install dependencies
RUN pip install --upgrade pip
RUN pip install -r requirements.txt

CMD ["python", "./ToDoApp/manage.py runserver 0.0.0.0:8000"]

and this is my docker-compose.yml

version: '3'

services:
  web:
    build: .
    command: python /ToDoApp/manage.py runserver 0.0.0.0:8000
    volumes:
        - .:/Desktop/Projects/ToDoApp
    ports:
        - "8000:8000"
    environment:
      - SECRET_KEY = please_change_me

Several issues I'm seeing:

  • The ADD command you use creates a file called ToDoApp/ToDoApp, it doesn't even create a sub directory.
  • ADD is unneeded (you're not extracting a tar or downloading from a URL) so that can switch to a COPY.
  • You need to copy your code.
  • The RUN commands can be reordered for better cache efficiency.
  • Use relative paths and the WORKDIR correctly.
  • Args need to be separated when you use the json syntax

The resulting Dockerfile looks like:

FROM python:3

#set envionment variables
ENV PYTHONUNBUFFERED 1

# run this before copying requirements for cache efficiency
RUN pip install --upgrade pip

#set work directory early so remaining paths can be relative
WORKDIR /ToDoApp

# Adding requirements file to current directory
# just this file first to cache the pip install step when code changes
COPY requirements.txt .

#install dependencies
RUN pip install -r requirements.txt

# copy code itself from context to image
COPY . .

# run from working directory, and separate args in the json syntax
CMD ["python", "./manage.py", "runserver", "0.0.0.0:8000"]

Try this:

FROM python:3

#set envionment variables
ENV PYTHONUNBUFFERED 1

#set work directory
WORKDIR /ToDoApp

# Adding requirements file
ADD requirements.txt /ToDoApp/

#install dependencies
RUN pip install --upgrade pip
RUN pip install -r requirements.txt

CMD ["python", "./ToDoApp/manage.py runserver 0.0.0.0:8000"]
