Как починить docker контейнер mysql?

Хост: CentOS 7, после перезагрузки сервера перестал подниматься докер контейнер с mysql базой

2021-02-10T13:12:40.364242Z 0 [ERROR] Could not open unix socket lock file /var/run/mysqld/mysqld.sock.lock.
2021-02-10T13:12:40.364250Z 0 [ERROR] Unable to setup unix socket lock file.
2021-02-10T13:12:40.364255Z 0 [ERROR] Aborting

Я понимаю, что mysql не может создать mysqld.sock.lock, но как это исправить или подключиться к выключенному контейнеру (если такое вообще возможно) ?

Как, вообще, быть в такой ситуации?

Если есть (актуальная) резервная копия данных, то стоит восстановить с нее. Это будет самый быстрый способ.

Если резервной копии нет, то попробуйте по этой статье:
https://dev.mysql.com/doc/refman/5.7/en/innodb-rec...

А вот как, собственно, извлечь данные с контейнера:
https://morioh.com/p/dbde4658c10e

В следующий раз примонтируйте данные к контейнеру и наладьте регулярное создание копии.
