我在使用laravel5/mysql应用程序访问docker容器中的adminer时遇到问题。我有个错误：
SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Name does not resolve我的docker-compose.yml：

command: composer install --ignore-platform-reqs我有不同的应用程序和数据库容器端口。
在这里https://hub.docker.com/_/adminer/ 我发现：
使用外部服务器可以使用adminer\u default\u server环境变量指定默认主机。如果要连接到外部服务器或docker容器（名称不是默认db），则此选项非常有用。
docker run -p 8080:8080 -e ADMINER_DEFAULT_SERVER=mysql adminer在我的应用程序控制台我运行命令
$ docker run -p 8089:8080 -e ADMINER_DEFAULT_SERVER=votes_db adminer在我的应用程序端口中使用了unused，并且这个命令无论如何都没有成功，因为我在尝试登录到adminer时遇到了相同的错误https://imgur.com/a/4hcdc1w.
哪条路对？
修改块#2：
在my docker-compose.yml中：

command: composer install --ignore-platform-reqs我重建了应用程序，但未能登录adminer:https://imgur.com/a/jwvgfba
我在操作系统的控制台中运行，指向其他未使用的8089端口：
$ docker run -p 8089:8080 -e ADMINER_DEFAULT_SERVER=db adminer
PHP 7.2.11 Development Server started at Thu Nov 1 07:00:46 2018

怎么了？
修改块#3：
我想是的，因为在我重新构建了容器之后，我进入了这个框，并在控制台输出中看到了“root”：

这个问题已经被回答了，但是在这里添加我对一个类似问题的解决方案以供参考。
在docker compose phpmyadmin/adminer服务块中添加一个'links'参数可以为我解决这个问题，因为假设数据库块的服务名实际上是db，正如上面的示例中所使用的那样。通过此链接，可以在phpmyadmin登录界面中使用“db”作为主机并进行连接。
hxzsmxv22#
你可以在报纸上看到https://hub.docker.com/_/adminer/
例子
uajslkp63#
设置中的问题是由于环境变量引起的
DB_PATH_HOST. 你已经在你的写作文件中设置好了一切。但是在运行docker compose之前，应该先定义环境变量DB_PATH_HOST. 因为没有定义环境变量，所以它会抛出一个错误。有关环境变量及其在docker中的优先级的更多详细信息，请参见本文。因此，您应该做的是，在启动docker容器之前，您应该在compose文件中定义环境变量，或者在运行docker compose之前在shell中将其导出为shell变量，或者应该使用env file，或者在dockerfile中使用env instrction来定义环境变量(这些都是定义环境变量的可能方法，我已经列出了所有这些方法，优先使用的方法。有关更多信息，请参阅此页）。
因此，正确的docker-compose.yml文件应该如下所示。
现在进入下一点，我从您的讨论中看到，您已经得出结论，从db容器中删除卷解决了您的问题。但实际上不是。怎样？
首先让我解释一下为什么这里使用音量。mysql生成的数据应该存储在某个地方。默认情况下，docker以非持久模式运行容器，这意味着运行docker容器生成的所有数据将在该容器关闭/终止时被擦除。因此，为了持久化（存储/保存）数据，我们使用卷。docker中使用了不同类型的卷。我鼓励您阅读docker的存储文档以了解更多详细信息。这里使用的卷类型是绑定装载，即将主机目录绑定到docker目录，docker将所有数据直接存储在主机中，这样即使docker容器关闭，数据仍然保留。
因此，如果您不在mysql中使用卷，那么无论您做什么，只要停止容器，所有db更改都将丢失。
奖励要点：
默认情况下，mysql容器不允许远程连接。所以如果你想从phpmyadmin之外的任何地方访问mysql。你必须允许远程连接。
因为我们在这里保存数据，所以只有在第一次启动mysqll容器时才会设置根密码。从下一次开始，root password环境变量将被忽略。
如果您使用dockerexec登录docker容器，您可以看到您将成为root用户。这是因为无论何时，只要使用
docker build或者docker-compose build除非你在Dockerfile要创建和使用新用户，docker将以root用户身份运行所有操作。现在每当您运行上面的compose文件时。您可以看到mysql数据位置的所有权将被更改。这是因为每当您将主机目录装载到docker时，docker都会根据该容器的docker定义根据用户和组更改文件权限。mysql在这里定义了一个名为
mysqluid和gid是999。因此/tmp/mysql将拥有999:999的所有权。如果这些id与系统中的任何其他用户帐户Map，那么每当您在主机中执行ls-al时，您将看到这些名称而不是id。如果id没有Map，那么您将直接看到id。例如，我使用了/tmp/mysql作为mysql数据目录。请不要使用相同的，因为只要系统重新启动，/tmp中的数据就会被删除。
