Создание ВМ по шагам

Дано: только что развернутый опенстек, в качестве внешнего роутреа используется ASR1001X
Требуется: Задеплоить 2 VM с Floating IP


openstack image create

Пример загрузки образа в OpenStack 

openstack \
    image create \
    --container-format bare  \
    --disk-format qcow2 \
    --file ~/Downloads/noble-server-cloudimg-amd64.img \
    Ubuntu-24.04

keypair create

Создать пару ключей, если нужно, приватную часть сохранить так как она больше нигде не сохраняется. 

openstack keypair create mmazur

Публичная сеть

openstack network create

 openstack network create --external public
  • --external public - сеть внешняя, использует для Floating IPs и будет маршрутизироваться наружу, за пределы OpenStack

openstack subnet create

Сабнет определяет диапазон адресов 

openstack subnet create \
     --network public \
     --subnet-range 10.170.6.0/24 \
     --allocation-pool start=10.170.6.201,end=10.170.6.249 \
     --dns-nameserver 8.8.8.8 \
     --gateway none \
