Question

我的前端（Vuejs）和后端（django）都有不同的Dockerfile，还有两个docker-compose文件来运行其开发服务器和测试阶段。它们在我的机器上运行得很好。但是，在Travis-CI上运行测试版本时，它们会出错。

docker-compose.yml：

version: "3.4"

services:
  database:
    image: postgres:alpine
    volumes:
      - postgres_data:/var/lib/postgresql/data/
    environment:
      - POSTGRES_USER=user
      - POSTGRES_PASSWORD=uni69204passwd
      - POSTGRES_DB=uni-db
  backend:
    build: ./backend/
    volumes:
      - ./backend:/app
    ports:
      - "8000:8000"
    depends_on:
      - database
  frontend:
    build: ./frontend/
    command: npm run dev
    ports:
      - "3000:3000"
    volumes:
      - ./frontend:/app
    depends_on:
      - database
      - backend

volumes:
  backend:
  frontend:
  postgres_data:

docker-compose.test.yml：

version: "3.4"

services:
  cypress:
    image: "cypress/included:3.4.0"
    environment:
      - CYPRESS_baseUrl=http://frontend:3000
    working_dir: /testing
    volumes:
      - ./frontend/:/testing
    entrypoint: "sh -c 'sleep 15; ./wait-for-it.sh frontend:3000 --strict -- cypress run'"

volumes:
  cypress:

.travis.yml：

language: node_js
node_js:
  - 14.8.0
services:
  - docker
before_script:
  - docker-compose run frontend sh -c "npm install"
script:
  - docker-compose -f docker-compose.yml -f docker-compose.test.yml up --abort-on-container-exit
  - docker-compose run --entrypoint "" backend pytest --flake8

frontend/Dockerfile：

FROM node:lts-alpine

EXPOSE 3000

# Use `node` user that `node:lts-alpine` provides
RUN mkdir -p /app && chown -R node /app

USER node

WORKDIR /app

backend/Dockerfile：

FROM python:3.8.5-alpine

EXPOSE 8000

# install psycopg2, pillow and argon2_cffi dependencies
RUN apk update && apk add postgresql-dev gcc python3-dev musl-dev libffi-dev openssl-dev jpeg-dev zlib-dev

RUN mkdir -p /app && adduser -D -h /app -u 1000 python && chown -R python /app

WORKDIR /app

ENV SECRET_KEY=e75)h*54&*^&(secret-keyd+=^%mb0n \

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

USER python

ENTRYPOINT [ "python", "manage.py", "runserver", "0.0.0.0:8000" ]

这是我在测试构建期间遇到的错误：

在您的前端 Dockerfile 中，当您在创建 chown 目录后对其进行 /apping 时，请尝试在用户名后添加 :。

即

RUN mkdir -p /app && chown -R node: /app

这将向用户和组 node 显示 /app。

也可能是您在 docker-compose 文件中使用 - ./frontend:/app 卷定义覆盖了它。

如何配置docker测试以在Travis CI上正确运行？
