如何将phpmyadmin添加到laravel 8 sail docker-compose.yml

Question

我正在尝试将 phpmyadmin 添加到 laravel 8 docker-compose.yml 文件。

现在，我可以访问“http://localhost:8080”上的 phpmyadmin，但是用户没有得到 无法登录:

Cannot log in to the MySQL server

mysqli::real_connect(): php_network_getaddresses: getaddrinfo failed: Name or service not known

mysqli::real_connect(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: Name or service not known

我的 docker-compose.yml 文件如下所示：

Answer 1

要让容器相互通信，它们必须在同一个 Docker 网络上。您已将 mysql 容器明确分配给 networks: [sail]，但 phpmyadmin 容器不在该网络上。您可以添加

services:
  phpmyadmin:
    networks:
      - sail

Compose 还为您提供了一个名为 default 的网络（有关详细信息，请参阅 Networking in Compose）。如果您没有明确指定 networks: 服务，那么它将在 default 网络上。另一种解决方案是只删除文件中各处的所有 networks: 块，让每个容器都在 default 网络上。

links: 仅与过时形式的 Docker 网络一起使用，您也可以删除文件的那部分内容。
