合成文件不适用于部署

Question

我正在使用Wonderfall nextcloud image通过一个组合文件进行部署。当使用docker stack deploy时，它似乎不会填充变量。

我已经尝试部署了几次，但都没有成功

version: '3.3'

networks:
  prodnet:
    external: true

services:
  nextcloud:
    image: wonderfall/nextcloud
    depends_on:
      - nextcloud-db # If using MySQL
      - redis # If using Redis
  ports:
    - 8888:8888
  deploy:
    replicas: 1
    placement:
      constraints: [node.role == worker]

# If using Redis
redis:

# If using MySQL

nextcloud-db:
  image: mysql:latest
  command: --default-authentication-plugin=mysql_native_password
  ports:
    - 3307:3306
  deploy:
    replicas: 1
    placement:
      constraints: [node.role == worker]

  volumes:
    - nextcloud_mysql:/var/lib/mysql

  environment:
    - MYSQL_ROOT_PASSWORD=supersecretpassword
    - MYSQL_DATABASE=nextcloud
    - MYSQL_USER=wonderfall
    - MYSQL_PASSWORD=supersecretpassword
  networks:
    - prodnet

volumes:
  nextcloud_data:
    driver: local
    driver_opts:
      type: nfs
      o: addr=xxxxxxxxxxxxx,hard,nolock,rw
      device: ":/mnt/array1/docker/nextcloud1/data"
  nextcloud_config:
    driver: local
    driver_opts:
      type: nfs
      o: addr=xxxxxxxxxxxxx,hard,nolock,rw
      device: ":/mnt/array1/docker/nextcloud1/config"
  nextcloud_apps:
    driver: local
    driver_opts:
      type: nfs
      o: addr=xxxxxxxxxxxxx,hard,nolock,rw
      device: ":/mnt/array1/docker/nextcloud1/apps2"
  nextcloud_themes:
    driver: local
    driver_opts:
      type: nfs
      o: addr=xxxxxxxxxxxxx,hard,nolock,rw
      device: ":/mnt/array1/docker/nextcloud1/themes"

  nextcloud_redis:
    driver: local
    driver_opts:
      type: nfs
      o: addr=xxxxxxxxxxxxx,hard,nolock,rw
      device: ":/mnt/array1/docker/nextcloud1/redis"

  nextcloud_mysql:
    driver: local
    driver_opts:
      type: nfs
      o: addr=xxxxxxxxxxxxx,hard,nolock,rw
      device: ":/mnt/array1/docker/nextcloud1/mysql"

映像已部署，但它是默认设置，并且正在尝试使用SQLite，而不是配置的映像。我正在遵循Wonderfall页面上的指导原则，但它不起作用。

您需要更多地缩进redis和nextcloud-db定义，它们应该与nextcloud处于同一级别，而不是与services处于同一级别。

[...]

services:
  nextcloud:
    image: wonderfall/nextcloud
    [...]

  # If using Redis
  redis:
    image: redis:alpine
    [...]

  # If using MySQL
  nextcloud-db:
    image: mysql:latest
    [...]

请参阅Dockerhub上的示例。
