Question

我正在开发Laravel应用程序。我正在使用docker-compose安装我的环境。我正在使用postgres作为数据库。

这是我的docker-compose.yml

version: '3'
services:
    apache:
        container_name: easy_eat_apache
        image: webdevops/apache:ubuntu-16.04
        environment:
            WEB_DOCUMENT_ROOT: /var/www/public
            WEB_ALIAS_DOMAIN: easy-eat.localhost
            WEB_PHP_SOCKET: php-fpm:9000
        volumes: # Only shared dirs to apache (to be served)
        - ./public:/var/www/public:cached
        - ./storage:/var/www/storage:cached
        networks:
        - easy-eat-network
        ports:
        - "80:80"
        - "443:443"
    php-fpm:
        container_name: easy_eat_php
        image: jguyomard/laravel-php:7.2
        volumes:
        - ./:/var/www/
        - ./ci:/var/www/ci:cached
        - ./vendor:/var/www/vendor:delegated
        - ./storage:/var/www/storage:delegated
        - ./node_modules:/var/www/node_modules:cached
        - ~/.ssh:/root/.ssh:cached
        - ~/.composer/cache:/root/.composer/cache:delegated
        networks:
        - easy-eat-network
    db:
        image: postgres
        restart: always
        ports:
        - 5432
        environment:
            POSTGRES_PASSWORD: secret
        volumes:
        - easy-eat-data:/var/lib/postgresql
networks:
    easy-eat-network:
        driver: "bridge"
volumes:
    easy-eat-data:
        driver: "local"

在Laravel的env文件中，我放入了这样的数据库凭据

DB_CONNECTION=pgsql
DB_HOST=db
DB_PORT=5432
DB_DATABASE=postgres
DB_USERNAME=postgres
DB_PASSWORD=secret

然后我运行迁移命令以查看我的应用程序是否能够连接到postgres。我收到此错误。

   Illuminate\Database\QueryException  : SQLSTATE[08006] [7] timeout expired (SQL: select * from information_schema.tables where table_schema = public and table_name = migrations)

  at /var/www/vendor/laravel/framework/src/Illuminate/Database/Connection.php:664
    660|         // If an exception occurs when attempting to run a query, we'll format the error
    661|         // message to include the bindings with SQL, which will make this exception a
    662|         // lot more helpful to the developer instead of just the database's errors.
    663|         catch (Exception $e) {
  > 664|             throw new QueryException(
    665|                 $query, $this->prepareBindings($bindings), $e
    666|             );
    667|         }
    668| 

  Exception trace:

  1   PDOException::("SQLSTATE[08006] [7] timeout expired")
      /var/www/vendor/laravel/framework/src/Illuminate/Database/Connectors/Connector.php:70

请问如何解决？

Answer 1

您的php-fpm容器已附加到easy-eat-network网络，但您的db容器未附加，因此它将附加到Docker Compose创建的默认网络。这将导致在容器之间解决和路由问题。

这里最简单的解决方案可能就是依靠Docker Compose为您创建的默认网络。删除所有networks:块，包括顶级服务和单个服务。

如果您确实要自己明确声明网络，则需要在networks: [easy-eat-network]服务块中添加db:节。

无法将Postgres与docker compose和Laravel一起使用
