Assign External IP to a Kubernetes Service

First of all run this command:

kubectl get -n namespace services

Above command will return output like this:

 NAME            TYPE       CLUSTER-IP       EXTERNAL-IP   PORT(S)         AGE
backend   NodePort   10.100.44.154         <none>          9400:3003/TCP   13h   
frontend        NodePort   10.107.53.39     <none>        3000:30017/TCP   13h

It is clear from the above output that External IPs are not assigned to the services yet. To assign External IPs to backend service run the following command.

 kubectl patch svc backend -p '{"spec":{"externalIPs":["192.168.0.194"]}}'

and to assign external IP to frontend service run this command.

 kubectl patch svc frontend -p '{"spec":{"externalIPs":["192.168.0.194"]}}'

Now get namespace service to check either external IPs assignment:

kubectl get -n namespace services

We get an output like this:

NAME     TYPE     CLUSTER-IP     EXTERNAL-IP    PORT(S)             AGE
backend  NodePort 10.100.44.154  192.168.0.194  9400:3003/TCP       13h
frontend NodePort 10.107.53.39   192.168.0.194  3000:30017/TCP      13h

Cheers!!! Kubernetes External IPs are now assigned .
