WiFi0 используется исключительно для настройки, в процессе работы никакой траффик через него ходить не будет
- В номерах VLAN для каждой ноды используется номер ноды что бы проще было запомнить
- Vlan 101, 201, 301 - используется для etcd
Master Nodes
- Три ноды которые будут играть роль как master так и worker нод
- Для лучшего понимания для каждого отдельного сервиса будет назначена своя сеть
