Dockerfile is copying files from outside of parent directory-CodePudding

I have a simple Dockerfile that is in a directory called /App when I build my docker container using a docker-compose yaml file the dockerfile copies files from one level up, outside the /App folder into the container. Here is my dockerfile

FROM python:3.8

ENV PYTHONUNBUFFERED 1

WORKDIR /code

COPY requirements.txt .
RUN pip install -r requirements.txt
COPY . .

and here is my docker-compose file

version: '3'

services:
  dash:
    build:
      context: ./App
      dockerfile: Dockerfile.dash
    container_name: dash_dash
    command: ls
    volumes:
      - .:/code
    ports:
      - "80:8080"

When I build and run the container the ls command shows that it copied the directory one level above the /App directory, such that the /App directory is included but is not the main directory.

CodePudding user response：

The volumes section of your docker-compose.yml is overriding the working directory:

    volumes:
      - .:/code

is copying the whole folder where the docker-compose.yml is (so it is copying the /App folder entirely). As a result, your files in your working directory (/code) are overridden.

You should remove the volumes section of your docker-compose.yml. The ls command will then show the contents of the App directory, copied by the COPY . . section of your Dockerfile.
