具有traefik（v2.1）和数据库网络的多个docker组成文件

Question

我想构建一个docker景观。我使用一个带有traefik（v2.1）图像的容器和一个用于多个数据库的mysql容器。

traefik / docker-compose.yml

version: "3.3"

services:
  traefik:
    image: "traefik:v2.1"
    container_name: "traefik"
    restart: always
    command:
      - "--log.level=DEBUG"
      - "--api=true"
      - "--api.dashboard=true"
      - "--providers.docker=true"
      - "--providers.docker.exposedbydefault=false"
      - "--providers.docker.network=proxy"
      - "--entrypoints.web.address=:80"
      - "--entrypoints.websecure.address=:443"
      - "--entrypoints.traefik-dashboard.address=:8080"
      - "--certificatesresolvers.devnik-resolver.acme.httpchallenge=true"
      - "--certificatesresolvers.devnik-resolver.acme.httpchallenge.entrypoint=web"
      #- "--certificatesresolvers.devnik-resolver.acme.caserver=https://acme-staging-v02.api.letsencrypt.org/directory"
      - "--certificatesresolvers.devnik-resolver.acme.email=####"
      - "--certificatesresolvers.devnik-resolver.acme.storage=/letsencrypt/acme.json"
    ports:
      - "80:80"
      - "443:443"
      - "8080:8080"
    volumes:
      - "./letsencrypt:/letsencrypt"
      - "./data:/etc/traefik"
      - "/var/run/docker.sock:/var/run/docker.sock:ro"
    networks:
      - "proxy"
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.traefik.rule=Host(`devnik.dev`)"
      - "traefik.http.routers.traefik.entrypoints=traefik-dashboard"
      - "traefik.http.routers.traefik.tls.certresolver=devnik-resolver"
      #basic auth
      - "traefik.http.routers.traefik.service=api@internal"
      - "traefik.http.routers.traefik.middlewares=auth"
      - "traefik.http.middlewares.auth.basicauth.usersfile=/etc/traefik/.htpasswd"

数据库/docker-compose.yml

version: "3.3"

services:
  #MySQL Service
  mysql:
    image: mysql:5.7
    container_name: mysql
    restart: always
    ports:
      - "3306:3306"
    volumes:
      #persist data
      - ./mysqldata/:/var/lib/mysql/
      - ./init:/docker-entrypoint-initdb.d
    networks:
      - "mysql"
    environment:
      MYSQL_ROOT_PASSWORD: ####
      TZ: Europe/Berlin

#Docker Networks
networks:
  mysql:
    driver: bridge

对于结构，我想通过多个docker-compose文件控制所有项目。这些容器应与traefik容器在同一网络上运行，而某些容器应与mysql容器一起运行。这也适用于以下情况（但仅在某些情况下）

dev-releases / docker-compose.yml

version: "3.3"

services:
  backend:
    image: "registry.gitlab.com/devnik/dev-releases-backend/master:latest"
    container_name: "dev-releases-backend"
    restart: always
    volumes:
      #laravel logs
      - "./logs/backend:/app/storage/logs"
      #cron logs
      - "./logs/backend/cron.log:/var/log/cron.log"
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.dev-releases-backend.rule=Host(`dev-releases.backend.devnik.dev`)"
      - "traefik.http.routers.dev-releases-backend.entrypoints=websecure"
      - "traefik.http.routers.dev-releases-backend.tls.certresolver=devnik-resolver"
    networks:
      - proxy
      - mysql
    environment:
      TZ: Europe/Berlin

#Docker Networks
networks:
  proxy:
    external:
      name: "traefik_proxy"
  mysql:
    external:
      name: "database_mysql"

我通过docker-compose up -d重新启动dev-releases /中的容器时，在浏览器中调用它们时，出现典型错误“网关超时”。一旦我注释了网络networks: #- mysql并在dev-releases /中重新启动docker-compose，它将再次起作用。

我的猜测是我没有正确配置外部网络。不能使用2个外部网络？我希望某些容器可以访问“ mysql”网络，但是整个traefik网络都不能访问它。

让我知道是否需要更多信息

编辑（26.03.2020）

我让它运行。

我将所有容器都放入一个网络“代理”中。看来mysql也必须在代理网络中。

所以我将以下内容添加到database / docker-compose.yml

networks:
  proxy:
    external:
      name: "traefik_proxy"

并从dev-releases / docker-compose.yml中移出了database_mysql网络>

我想构建一个docker景观。我使用一个带有traefik（v2.1）图像的容器和一个用于多个数据库的mysql容器。 traefik / docker-compose.yml版本：“ 3.3”服务：traefik：...

根据文件名，您的mysql网络应为mysql_mysql。您可以通过执行
