7.1.3 Service discovery

Get the name of the internal service created in 7.1.2

$ kubectl get svc
NAME                TYPE           CLUSTER-IP       EXTERNAL-IP     PORT(S)        AGE
kubernetes          ClusterIP      34.118.224.1     <none>          443/TCP        98m
robohash-internal   ClusterIP      34.118.234.111   <none>          80/TCP         6m28s
timeserver          LoadBalancer   34.118.238.176   35.233.155.58   80:32534/TCP   94m

We can reference this in the Deployment

And add a new endpoint /avatar to generate a Random robot

Replace the Deployment:

$ cd Chapter07/7.1_InternalServices
$ kubectl replace -f  timeserver-deploy-dns.yaml

Create the service if needed

$ kubectl create -f timeserver-service.yaml
service/timeserver created

Wait for the new Pods to become ready

watch kubectl get deploy

Get the IP of our main service:

$ kubectl get svc/timeserver -w
NAME         TYPE           CLUSTER-IP       EXTERNAL-IP     PORT(S)        AGE
timeserver   LoadBalancer   34.118.238.176   203.0.113.16   80:32534/TCP   95m

Append /avatar to the IP and browse to it. Refresh the page to generate different robots.
