docker-compose 构建镜像或构建上下文[关闭]

我想构建自定义 Dockerfile，但我收到以下消息： --> Starting build app ERROR: The Compose file is invalid because: Service app has neither an image nor a build context specified. At least one must be provided.

我不明白为什么这个名字app。你可以看到我的 docker-compose.yml 文件：

version: "3"

services:
  webapp-react:
    build:
      context: ./docker/nodejs
      dockerfile: Dockerfile
    image: webapp/react
    container_name: webapp_react
    user: ${UID}:${GID}
    environment:
      - NODE_ENV=build

  webapp-nginx:
    build:
      context: ./docker/nginx
      dockerfile: Dockerfile
    image: webapp/nginx
    container_name: webapp_nginx
    environment:
      - VIRTUAL_HOST=${SITE_URL}
      - VIRTUAL_PORT=8080
      - VIRTUAL_NETWORK=nginx-proxy
      - LETSENCRYPT_HOST=${SITE_URL}
      - LETSENCRYPT_EMAIL=${MAILER_DEFAUT_SENDER_ADDRESS}
    ports:
      - "8181:80"
    volumes:
      - ./app/build:/www-data/

networks:
  default:
    external:
      name: nginx-proxy

有人知道我哪里出错了吗？

谢谢 ！

就我而言，我已将服务重命名为docker-compose.yml文件，但忘记在中执行相同的操作docker-compose.override.yml and docker-compose.vs.release.yml.
