Невозможно запустить команды Redis с хоста Windows на сервере Redis, работающем в контейнере Docker на моем WSL2. ⇐ C#

[Anonymous]

Я запускаю redis-stack в контейнере Docker на своем экземпляре WSL2:

mark@L-R910LPKW:~$ docker ps
CONTAINER ID  IMAGE                               COMMAND         CREATED       STATUS           PORTS                                           NAMES

mark@L-R910LPKW:~$

На самом хосте Windows я могу перейти по адресу http://localhost:8001 и получить доступ к графическому интерфейсу Redis Insights, работающему в том же контейнере. Он отлично отображает данные.
В WSL2 я без проблем могу подключиться к серверу Redis. У меня нет клиента redis-cli (кроме того, который доступен в контейнере), поэтому я буду использовать команду nc для запуска команды Redis PING:

mark@L-R910LPKW:~$ nc localhost 6379
ping
+PONG
^C
mark@L-R910LPKW:~$

На хосте Windows у меня нет ни клиента Redis, ни инструмента NC. Но у меня есть git-bash и это работает:

/c/dayforce/aida$ exec 3/dev/tcp/localhost/6379

/c/dayforce/aida$ echo -e "PING\r\n" >&3

/c/dayforce/aida$ cat  Encoding.UTF8;
}

public class LocalRedis
{
private readonly IConnectionMultiplexer sut;

public LocalRedis(ITestOutputHelper testOutputHelper)
{
if (Environment.GetEnvironmentVariable("TF_BUILD") == null)
{
sut = ConnectionMultiplexer.Connect("localhost,abortConnect=false", new XUnitTextWriter(testOutputHelper));
}
}

[SkippableFact]
public void Ping()
{
Skip.If(sut == null, $"{GetType().Name} tests can only run locally.");

var db = sut.GetDatabase();
db.Ping();
}
}

И эта штука терпит неудачу:

(По какой-то причине трассировка стека и захваченные выходные данные печатаются дважды — один раз с префиксом [xUnit.net 00:00:...], а затем без префикса, поэтому я для краткости заменил последнее многоточием)
Я новичок в Redis, и мне совершенно непонятно, что происходит. Кроме того, меня озадачил следующий вывод при запуске модульного теста:

Код: Выделить всё

localhost:6379: Standalone v3.0.0, ...

Интересно, что это значит, учитывая, что команда INFO сообщает версию сервера как 7.4.0.
Изменить 1
Я заменил localhost на 127.0.0.1, и всё заработало. Итак, теперь вопрос: в чем проблема с localhost в .NET, ведь в Git Bash он отлично работал.
