Я начал с Kubernetes в последнее время и получил некоторый опыт использования Minikube и, конечно, kubectl.Теперь я хотел настроить свой собственный кластер и следовал этому официальному описанию: Установка Fedora (Single Node)
Мастер и узел могут подключаться, и состояние узла «готово»:
[root@fed-master ~]# kubectl get nodes
NAME STATUS ROLES AGE VERSION
fed-node Ready <none> 22h v1.10.1
Но при создании развертывания:
[root@fed-master ~]# kubectl run hello-world --replicas=2 --labels="run=load-balancer-example" --image=gcr.io/google-samples/node-hello:1.0 --port=8080
POD не создаются и недоступны:
[root@fed-master ~]# kubectl get deployments
NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE
hello-world 2 0 0 0 21h
Я заметил, что мне не хватает кубаPOD -системы, которые доступны в среде Minikube, но отсутствуют в моей настройке Fedora:
[root@fed-master ~]# kubectl get pods --all-namespaces=true
No resources found.
Вывод «kubectl описывает deploy hello-world»:
[root@fed-master ~]# kubectl describe deploy hello-world
