Question

我无法使用Symfony 4上的Doctrine Migration捆绑包。我在Docker容器中启动Web应用程序。在容器启动后要执行迁移的尝试上，迁移失败并显示“连接被拒绝”异常。但是：

当我尝试从主机或FPM容器连接到它自己的容器中的MySQL时，它工作正常
使用Doctrine的命令执行后，效果很好。

示例：

root@3af0cf70b099:/var/www# php bin/console doctrine:migration:migrate -qn

In StreamSocketClient.php line 225:

  Failed to write to socket: fwrite(): send of 185 bytes failed with errno=111 Connection refused (8)


doctrine:migrations:migrate [--write-sql [WRITE-SQL]] [--dry-run] [--query-time] [--allow-no-migration] [--configuration [CONFIGURATION]] [--db-configuration [DB-CONFIGURATION]] [--db DB] [--em EM] [--shard SHARD] [-h|--help] [-q|--quiet] [-v|vv|vvv|--verbose] [-V|--version] [--ansi] [--no-ansi] [-n|--no-interaction] [-e|--env ENV] [--no-debug] [--] <command> [<version>]

root@3af0cf70b099:/var/www# php bin/console dbtest


 [OK] Found user with login demo


root@3af0cf70b099:/var/www# php bin/console doctrine:migration:migrate -qn

In StreamSocketClient.php line 225:

仅在容器启动后20秒钟以上才能进行迁移。
我的学说配置：

doctrine:
    dbal:
        # configure these for your database server
        driver: '%env(DB_DRIVER)%'
        server_version: '%env(DB_SERVER_VERSION)%'
        charset: '%env(DB_CHARSET)%'
        default_table_options:
            charset: '%env(DB_CHARSET)%'
            collate: '%env(DB_COLLATION)%'
        mapping_types:
            enum: string
        types:
            phone_number: Misd\PhoneNumberBundle\Doctrine\DBAL\Types\PhoneNumberType
        url: 'mysql://%env(DB_USER)%:%env(MYSQL_ROOT_PASSWORD)%@%env(DB_HOST)%:%env(DB_PORT)%/%env(MYSQL_DATABASE)%'
    orm:
        auto_generate_proxy_classes: false
        naming_strategy: doctrine.orm.naming_strategy.underscore
        auto_mapping: true
        mappings:
            App:
                is_bundle: false
                type: annotation
                dir: '%kernel.project_dir%/src/Entity'
                prefix: 'App\Entity'
                alias: App

文档迁移配置为默认设置：

doctrine_migrations:
    dir_name: '%kernel.project_dir%/src/Migrations'
    # namespace is arbitrary but should be different from App\Migrations
    # as migrations classes should NOT be autoloaded
    namespace: DoctrineMigrations

您需要等待所有docker服务完全加载。参见：https://docs.docker.com/compose/startup-order/
