kubernetes - how to local load balancer

Pre-requirements:

1. Docker desktop installed.
2. Kubernetes enabled
3. Some services already created and running:

kubectl.exe get all                                                             NAME                             READY STATUS RESTARTS AGE                 pod/httpenv-dd7475946-69wj8      1/1     Running   0          15h               pod/httpenv-dd7475946-6ncsb      1/1     Running   0          15h               pod/httpenv-dd7475946-cf46s      1/1     Running   0          15h               pod/httpenv-dd7475946-lclml      1/1     Running   0          15h               pod/httpenv-dd7475946-nv4br      1/1     Running   0          15h                                                                                                NAME                 TYPE CLUSTER-IP       EXTERNAL-IP PORT(S) AGE   service/httpenv      ClusterIP 10.111.175.59    <none>        8888/TCP   15h                                                                                    NAME                        READY UP-TO-DATE AVAILABLE   AGE deployment.apps/httpenv     5/5     5            5           15h                                                                                                                NAME                                   DESIRED CURRENT READY AGE     replicaset.apps/httpenv-dd7475946      5         5         5       15h

Create LoadBalancer:

1. Create LoadBalancer as following

kubectl.exe expose deployment.apps/httpenv --port 8888 --name httpenv-lb --type LoadBalancer                                                                     
service/httpenv-lb exposed        

2. Check the load balancer created

kubectl.exe get service                                                             NAME         TYPE           CLUSTER-IP       EXTERNAL-IP PORT(S)          AGE httpenv      ClusterIP   10.111.175.59   <none> 8888/TCP         15h httpenv-lb   LoadBalancer   10.102.229.139   localhost 8888:31050/TCP   28s

                                                                                                                                                                       

3. Test                                                                                                                                                                               

curl localhost:8888
