Question

我正在尝试进行docker-compose构建，但是nginx返回此错误：

rm: cannot remove '/etc/nginx/conf.d/default.conf': No such file or directory
ERROR: Service 'nginx' failed to build: The command '/bin/sh -c rm /etc/nginx/conf.d/default.conf' returned a non-zero code: 1

还有docker-compose.yml和Dockerfile：

version: '3'
volumes:
  pgdata:
services:
  python:
    build:
      context: .
      dockerfile: docker/python/Dockerfile
    environment:
      - DJANGO_SETTINGS_MODULE=sphinx_django.settings.prod
    ports:
    - 8000:8000
    depends_on:
      - db
    command: gunicorn -w 4 sphinx_django.wsgi:application -b 0.0.0.0:8000
  db:
    image: postgres:10.3
    restart: always
    environment:
      POSTGRES_USER: '121211'
      POSTGRES_HOST: db
      POSTGRES_PASS: '55555'
    volumes:
    - pgdata:/var/lib/postgresql/data
    ports:
    - "5432:5432"
  nginx:
     build:
       context: .
       dockerfile: docker/nginx/Dockerfile
     restart: always
     ports:
       - 8080:80
     depends_on:
        - python

和Dockerfile：

FROM nginx:latest

RUN rm /etc/nginx/conf.d/default.conf

COPY ./docker/nginx/nginx.conf /etc/nginx/conf.d/

Answer 1

复制您的Dockerfile时，我得到：

Error response from daemon: Dockerfile parse error line 2: unknown instruction:

我认为这是编码问题。尝试将Dockerfile转换为UTF-8。

Answer 2

Context用于指定构建Dockerfile的位置：

上下文：

包含Dockerfile的目录的路径或url 到git仓库。

根据项目的结构，default.conf位于Dockerfile所在的目录内。

您的Dockerfile应该是这样的：

FROM nginx:latest

RUN rm /etc/nginx/conf.d/default.conf

COPY ./nginx.conf /etc/nginx/conf.d/
