Как я могу это исправить?
Похоже, что функции Cgroups, необходимые для Docker, не поддерживаются вашим текущим ядром. Вы используете Debian? В любом случае эти предупреждения показывают, что к контейнерам Docker нельзя применять ограничения памяти, ЦП и свопинга. Вам следует обновить ядро, если они вам нужны / нужны.
Была такая же проблема на Xenial, и я собирался перекомпилировать ядро в соответствии с потребностями докера, но не нашел ни одного из выключателей, деактивированных в текущей конфигурации, как это утверждалось. Оказалось: как только я удалил (--purge) все пакеты докеров, включая cgroupfs-mount и aufs-tools, и снова установил ту же версию докера, все заработало. Думаю, это вызвано чем-то в деталях какого-то необходимого пакета. Как ни странно.
