docker工MariaDb – 远程访问

我试图设置通过Traefik远程访问MariaDb：

MariaDB docker-compose.yml

version: "2" services: jpz-mariadb: image: mariadb:latest environment: - MYSQL_ROOT_PASSWORD=root - MYSQL_DATABASE=database - MYSQL_USER=user - MYSQL_PASSWORD=pass networks: - web volumes: - ./db:/docker-entrypoint-initdb.d - jpz-mariadb:/var/lib/mysql:nocopy # I want to manage volumes manually. labels: - 'traefik.backend=jpz-mariadb' - 'traefik.frontend.rule=Host:mariadb.localtest.me' jpz-pma: image: phpmyadmin/phpmyadmin environment: PMA_HOST: jpz-mariadb PHP_UPLOAD_MAX_FILESIZE: 1G PHP_MAX_INPUT_VARS: 1G networks: - web labels: - 'traefik.backend=jpz-pma' - 'traefik.frontend.rule=Host:pma.localtest.me' volumes: jpz-mariadb: external: true networks: web: external: name: traefik_webgateway 

和Traefik docker-compose.yml

 version: '2' services: proxy: image: traefik command: --web --docker --docker.domain=localtest.me --logLevel=DEBUG networks: - webgateway ports: - "81:80" - "3307:3306" - "443:443" - "8081:8080" volumes: - /var/run/docker.sock:/var/run/docker.sock - /dev/null:/traefik.toml networks: webgateway: driver: bridge 

我无法通过mysql连接到mariadb.localtest.me:3307 -u root -p -h mariadb.localtest.me -P 3307

获得：

系统错误：0（Mysql2 :: Error）

如何解决它？

谢谢
