У меня есть несколько экземпляров CoreOS bare metal, которые демонстрируют необычное поведение на мостовом устройстве docker0.
В одном из случаев, когда это происходило, я запускаю сервер couchbase, и это вызвало некоторые проблемы с перебалансировкой. Когда я переместил couchbase на узел, где этого не происходило, эта проблема исчезла.
Что может быть причиной этого? что определяет состояние мостового устройства?
аппаратное обеспечение идентично. Конфигурация идентична, за исключением IP-адреса.
