我正在尝试使用Traefik作为MariaDB的反向代理，以便可以从我的客户端连接。
目前Traefik在多个WordPress容器的HTTP和HTTPS上运行良好，但我在为MariaDB配置它时遇到了麻烦。
以下是当前配置：
Traefik合成文件：

version: '3.5'

 networks:
  traefik:
    name: traefik

services:
  traefik:
    image: traefik:latest
    restart: always
    container_name: traefik
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - ./traefik.toml:/traefik.toml:ro
      - ./acme.json:/acme.json
    ports:
      - 80:80
      - 443:443
      - 3306:3306
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.traefik.rule=Host(`traefik.local`)"
      - "traefik.http.routers.traefik.entrypoints=websecure"
      - "traefik.http.routers.traefik.service=api@internal"
      - "traefik.http.routers.traefik.middlewares=auth"
      - "traefik.http.middlewares.auth.basicauth.users=username:$$apr1$$j994eiLb$$KmPfiii4e9VkZwTPW2/RF1"
    networks:
      - traefik

Traefik配置文件（traefik.toml）：

# Network traffic will be entering our Docker network on the usual web ports
# (ie, 80 and 443), where Traefik will be listening.
[entyPoints]
  [entryPoints.web]
    address = ":80"

  [entryPoints.websecure]
    address= ":443"
    [entryPoints.websecure.http.tls]
      certResolver = "resolver"

#  [entryPoints.ssh]
#    address = ":2222"

  [entryPoints.mariadb]
    address = ":3306"

    #Redirection from HTTP to HTTPS
    [entryPoints.web.http]
      [entryPoints.web.http.redirections]
        [entryPoints.web.http.redirections.entryPoint]
        to = "websecure"
        scheme = "https"

#Integration with Let's Encrypt
[certificatesResolvers.resolver.acme]
  email = "service@local"
  storage = "acme.json"
  [certificatesResolvers.resolver.acme.tlsChallenge]

#[log]
#  level = "DEBUG"

[api]
  #Defaul=true
  dashboard = true

# Enable retry sending request if network error
[retry]

# These options are for Traefik's integration with Docker.
[providers.docker]
  endpoint = "unix:///var/run/docker.sock"
  exposedByDefault = false
  network = "traefik"

MariaDB合成文件：版本：“3.5”

networks:
  traefik:
    external:
      name: traefik

services:
  dbtest:
    image: mariadb:latest
    restart: always
    container_name: dbtest
    environment:
      - MYSQL_DATABASE=admin
      - MYSQL_USER=admin
      - MYSQL_PASSWORD=admin
      - MYSQL_ROOT_PASSWORD=admin
    networks:
      - traefik
    labels:
      - "traefik.enable=true"
      - "traefik.docker.network=traefik"
      - "traefik.tcp.routers.mariadb.entrypoints=mariadb"
      - "traefik.tcp.routers.mariadb.rule=HostSNI(`test.local`)"
      - "traefik.tcp.routers.mariadb.tls=true"
#      - "traefik.tcp.routers.mariadb.service=dbtest"
#      - "traefik.tcp.services.mariadb.loadbalancer.server.port=3306"

当我尝试从客户端连接到数据库时，无法正常工作
有人有经验或者有好的例子吗？
