Launch pods into Secondary CIDR network

Let’s launch few pods and test networking

kubectl create deployment nginx --image=nginx
kubectl scale --replicas=3 deployments/nginx
kubectl expose deployment/nginx --type=NodePort --port 80
kubectl get pods -o wide

NAME                     READY     STATUS    RESTARTS   AGE       IP              NODE                                           NOMINATED NODE
nginx-64f497f8fd-k962k   1/1       Running   0          40m    ip-192-168-52-113.us-east-2.compute.internal   <none>
nginx-64f497f8fd-lkslh   1/1       Running   0          40m    ip-192-168-74-125.us-east-2.compute.internal   <none>
nginx-64f497f8fd-sgz6f   1/1       Running   0          40m   ip-192-168-26-65.us-east-2.compute.internal    <none>
You can use busybox pod and ping pods within same host or across hosts using IP address

kubectl run -i --rm --tty debug --image=busybox -- sh

Test access to internet and to nginx service
