登录后的Docker phpmyadmin : 504网关超时

Question

尝试使用连接多个mysql的本地(容器)和远程服务器。在我开始登录之前，一切都很好--连接到远程服务器就像一种魅力，问题是如何连接本地服务器的容器。我的写作中心是这样的：

version: '3'

services:
  phpmyadmin:
    image: phpmyadmin_4.7.6
    container_name: phpmyadmin
    restart: always
    ports:
      - "8081:80"
    volumes:
      - "./conf_phpmyadmin/:/root/confs/"
      - "/sessions"
    networks:
      proxy:
        ipv4_address: "172.18.0.4"
    environment:
      - PMA_ABSOLUTE_URI=https://<access-url>/phpmyadmin/
      - PMA_HOSTS=172.21.0.3,192.168.1.65
      - PMA_VERBOSES=LocalMysqlContainer,RemoteMySql
    links:
      - mysql-5.7:mysql

  php7:
    restart: always
    image: php7-phalcon
    hostname: <hostname>
    container_name: <container name>
    expose:
      - 82
    # add static IP in case of restart
    networks:
      network1:
        ipv4_address: "172.21.0.2"
      proxy:
    environment:
      - VIRTUAL_HOST=${VIRTUAL_HOST}
      - LETSENCRYPT_HOST=${VIRTUAL_HOST}
      - LETSENCRYPT_EMAIL=${EMAIL}

  mysql-5.7:
    restart: always
    image: prod-mysql
    container_name: mysql
    # add static IP in case of restart
    networks:
      network1:
        ipv4_address: "172.21.0.3"
    volumes:
      - "/var/lib/mysql"
    environment:
      MYSQL_ROOT_PASSWORD: ${MYSQL_ROOT_PASS}

# create custom network
networks:
  proxy:
    external:
      name: webproxy_proxy
  network1:
    driver: bridge
    ipam:
      config:
        - subnet: "172.21.0.0/24"

• 尝试将mysql容器添加到与nginx代理相同的网络(与phpmyadmin相同的子网)。
• 尝试了不同的端口和IP-s和变体。
