error in the service page about service name and service port. #39

Closed survivant closed 2 years ago

survivant commented 3 years ago

in the page : https://github.com/redhat-scholars/kubernetes-tutorial/edit/master/documentation/modules/ROOT/pages/service.adoc image

The name of the service should be : the-service (from the metadata) and not myapp

if I do : kubectl get svc -o wide I'll obtain this

vagrant@k8s-master ~ $ kubectl get svc -o wide
NAME                                                   TYPE           CLUSTER-IP       EXTERNAL-IP      PORT(S)                         AGE    SELECTOR

vagrant@k8s-master ~ $

PS. Look at the port also, it's 80:(generated nodeport). in your example, it's 8080. PS2. I'm running on-premise with MetalLB.
