Deploy an app

$ microk8s kubectl create deployment kubernetes-bootcamp --image=gcr.io/google-samples/kubernetes-bootcamp:v1
deployment.apps/kubernetes-bootcamp created

$ microk8s kubectl get pods
NAME                                   READY   STATUS    RESTARTS   AGE
kubernetes-bootcamp-6f6656d949-7bhlv   1/1     Running   0          6m44s

$ microk8s kubectl logs kubernetes-bootcamp-6f6656d949-7bhlv
Kubernetes Bootcamp App Started At: 2020-04-11T06:37:09.171Z | Running On:  kubernetes-bootcamp-6f6656d949-7bhlv 

再用一个docker nginx 官方的镜像作为例子

$ kubectl create deployment nginx --image=nginx
deployment.apps/nginx created
$ kubectl get deployments
NAME                  READY   UP-TO-DATE   AVAILABLE   AGE
kubernetes-bootcamp   1/1     1            1           67m
nginx                 1/1     1            1           4s
$ kubectl get pods
