Lab 8.1 / 8.2 Questions
In lab 8.1 using the nginx-one.yaml I am creating a deployment within the namespace accounting.
The deployment is sucessfull created and afterwards exposed on step 10 and on step 13 recreated to expose port 80.
joaocfernandes@master-node:~$ kubectl --namespace=accounting get ep nginx-one NAME ENDPOINTS AGE nginx-one 10.244.1.42:80,10.244.1.43:80 17m joaocfernandes@master-node:~$ kubectl get service --all-namespaces NAMESPACE NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE accounting nginx-one ClusterIP 10.97.119.130 <none> 80/TCP 18m default kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 17d kube-system kube-dns ClusterIP 10.96.0.10 <none> 53/UDP,53/TCP 17d joaocfernandes@master-node:~$ kubectl -n accounting describe service nginx-one Name: nginx-one Namespace: accounting Labels: system=secondary Annotations: <none> Selector: app=nginx Type: ClusterIP IP: 10.97.119.130 Port: <unset> 80/TCP TargetPort: 80/TCP Endpoints: 10.244.1.42:80,10.244.1.43:80 Session Affinity: None Events: <none>
In the step 13, we are asked to recreate the deployment to expose port 80. So in order to prove this I should curl 10.97.119.130:80 or the pods directly 10.244.1.42:80/10.244.1.43:80 ?
Previously to step 13 I first exposed port 8080, then exposed 80. Is it necessary to expose the deployment again in order to update the exposed port? (I had to in my case or I did something wrong).
