Я установил Kubernetes, выполнив следующие шаги. Все выглядит отлично, но работает на одном узле/сервере.kubernetes set список всех физических узлов
Теперь я хочу сделать следующий шаг для работы на нескольких узлах. Интересно, где я должен настроить IP-адреса физических серверов, чтобы я мог создать модуль на более чем одном физическом сервере.
Я бегу:
hack/local-up-cluster.sh
затем (в другом терминале):
cluster/kubectl.sh config set-cluster local --server=http://127.0.0.1:8080 --insecure-skip-tls-verify=true
cluster/kubectl.sh config set-context local --cluster=local
cluster/kubectl.sh config use-context local
И:
cluster/kubectl.sh create -f run-aii.yaml
