Всем привет. Разворачиваю кластер kubernetes тестовы. Но столкнулся с проблемой:
1. Установил везде кубер и докер, выполнил подготовительные настройки.
2. Инициализировал кластер на мастере.
3. Добавил в кластер 2 рабочих ноды.
4. Установил сетевой плагин Calico.
После этого мастер встал в стату Ready, а 2 рабочих ноды так и остались в NotReady.
Подскажите куда смотреть? В describe вижу что плагин не установлен. Но насколько я понял, он ставиться на местере, на мастере я установил все.
