无法通过主机浏览器访问 docker 容器。允许 Ping答案

【问题标题】：Can't access docker container via host browser. Ping is allowed无法通过主机浏览器访问 docker 容器。允许 Ping
【发布时间】：2021-12-09 02:18:07
【问题描述】：

我第一次通过 docker-compose 在同一个新网络中创建了一些容器。在环境完成之后。我看到通过 docker ps 运行容器。通常在那之后我可以使用容器。但是当我尝试通过 localhost:20000 或 :20000 从主机访问 wordpress 网页时。我收到 ERR_Connection 被拒绝。我期待有关“连接到数据库时出错”的信息。我可以通过主机的 docker 容器 ip ping 容器。所以也许有人知道如何解决这个问题并访问它们。

这种情况发生在这个新网络 - network_1 上。其他容器，如默认桥接网络中的 pihole + portainer 可以从整个主机网络访问。谢谢。

【问题讨论】：

显示docker container logs 52d11a5c2931的输出
我在第一篇文章中添加了 - 它工作但很慢......我无法访问 phpmyadmin - 它响应 DNS_PROBE_FINISHED_NXDOMAIN。一些超时？在码头？我不知道。
所以它检测到来自外部的呼叫？（因为记录了一些 GET/POST 请求）
我从其他容器添加了日志 - 我无法访问。这是 Raspberry 的性能限制吗？
后者可能是由于容器中某处的执行命令语法不正确造成的。 stackoverflow.com/questions/42494853/…

【解决方案1】：

我认为

  # Database
  db:
    image: linuxserver/mariadb
    volumes:
      - db_data:/var/lib/mysql
    restart: always
        ports:
      - 3306:3306

应该是

  # Database
  db:
    image: linuxserver/mariadb
    volumes:
      - db_data:/var/lib/mysql
    restart: always
    ports:
      - 3306:3306

【讨论】：

我试过了 - 结果一样。

【解决方案2】：

尝试另一张图片。几次更新后，我在使用 linuxserver 映像时遇到了很多麻烦。 mariadb 在 docker 上有官方图片。或者，如果您还想继续使用 linuxserver 映像，请尝试另一个 mariadb 映像版本。
