Commands

Запустили minikube:

minikube start
# wait until start

Затем через kubectl (alias) запускаем деплоймент и сервис:

ztvgzh@Ubuntu:~/Documents/app$ kubectl apply -f deployment.yaml 
deployment.apps/test created
ztvgzh@Ubuntu:~/Documents/app$ kubectl apply -f service.yaml 
service/my-service created

Проверяем:

ztvgzh@Ubuntu:~/Documents/app$ kubectl get all

Получаем с помощью команды describe больше информации о сервисе:

ztvgzh@Ubuntu:~/Documents/app$ kubectl describe service/my-service
Name:                     my-service
Namespace:                default

Делаем проброс портов через port-forward, у меня они пробразываются по отдельности:

ztvgzh@Ubuntu:~/Documents/app$ kubectl port-forward pod/test-6bbcbccb7f-ln474 32777:32777
Forwarding from 127.0.0.1:32777 -> 32777
Forwarding from [::1]:32777 -> 32777
Handling connection for 32777
Handling connection for 32777
Handling connection for 32777

Result

Результат можно увидеть на localhost:32777 в браузере:

Delete everything

minikube delete
# wait until finish

minikube stop
# wait until finish
