使用 laravel 构建 Docker - SQLSTATE[HY000] [2002]

Question

在构建 docker 容器后，我的 docker 映像出现错误。

在 docker-compose up -d 命令上，应用程序连接到数据库。

但是当我尝试运行 docker build -t 来制作图像时 运行它，我得到 500 内部错误 php_network_getaddresses: getaddrinfo failed:

我尝试用这些更改 .env 文件。

DB_HOST=127.0.0.1 错误 -> SQLSTATE[HY000] [2002] 连接被拒绝

DB_HOST=localhost 错误 -> SQLSTATE[HY000] [2002] 没有这样的文件或目录

DB_HOST=172.19.0.3 ERROR -> SQLSTATE[HY000] [2002] 操作超时

容器 IP 使用 docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' container_id

如果我没记错的话，它要么与包/库或权限有关。检查行：

RUN chown -R www-data:www-data /var/www

它确保您获得正确的权限。

很抱歉，我无法提供更多详细信息。
