2>create pod with 3 replication
kubectl run nginx --image=nginx --replicas=3 -n test
3>Pod exposed ports for nginx (target port, source port target-port)
kubectl expose deployment nginx --port=88 --target-port=80 --type=LoadBalancer -n test
or
kubectl expose deployment nginx --port=88 --target-port=80 --type=NodePort -n test

4> Check svc(ports that pod exposed , The cluster internally accesses this pod via port 88., external access to the cluster using floatingip+30531)
kubectl get svc -n test
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
nginx LoadBalancer 10.43.45.186 10.0.0.3 88:30531/TCP 3m
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
nginx NodePort 10.43.45.186 88:30531/TCP 3m
Nodes within the CLUSTER can be accessed via cluster-ip +88 port
Outside the cluster, it is accessible via either EXTERNAL IP or the Floating IP+30531, which is the node name of the pod
The floatingip corresponding to the node name can be viewed in the /etc/hosts of the rancher machine or in the documentation
