Lab 9.1 Deployment Endpoint
Hello,
Just following the [link to copyrighted content removed]
last step:
containerPort: 8080
modified to
containerPort: 80
and even after deleting the endpoint it still shows:
student@master:~/src/lfs258$ kubectl -n accounting get endpoints nginx-one
NAME ENDPOINTS AGE
nginx-one 192.168.171.88:8080,192.168.171.89:8080 14m
any idea how to fix it?
Also,
in [link to copyrighted content removed]
"Exercise 9.2: Configure a NodePort
[Copyrighted content removed]" but there was no LoadBalancer involved.
Any idea how to fix these?

Hi @toma,
The
nginx-one
service needs to be re-created in order for the endpoints to show the correct port number.If you revisit an earlier Exercise 3.5, you will find the LoadBalancer type service.

Thank you @chrispokorni, I deleted, recreated with 80, nothing changed.

Hi @toma,
After re-creating the
nginx-one
deployment, can youdescribe
one of its pod replicas and confirm that thenginx
container has its Port set to 80?Regards,

Coincidentally I was also just stuck here - lab 9.1 seemed to end very abruptly without reaching a final state...
Simply recreating the pods to listen on port 80 did not seem to be sufficient for me either.
I ran
ubuntu@k8s-master:~$ kubectl describe -n accounting service nginx-one
and saw the service is still using 8080:Name: nginx-one Namespace: accounting Labels: system=secondary Annotations: <none> Selector: system=secondary Type: ClusterIP IP Family Policy: SingleStack IP Families: IPv4 IP: 10.99.168.32 IPs: 10.99.168.32 Port: <unset> 8080/TCP TargetPort: 8080/TCP Endpoints: 192.168.254.136:8080,192.168.254.140:8080 Session Affinity: None Events: <none>
So I did
kubectl -n accounting delete service nginx-one
and then repeatedkubectl -n accounting expose deployment nginx-one
. Now curl to both endpoints listed inkubectl -n accounting get ep nginx-one
works for me. Just not sure if this was the intended final result.0 -
That is the expected result, but for Exercise 9.2 Step 1, where the nginx-one deployment is exposed once more.

Hi @toma,
Just deleting the endpoints does not update the target port of the service. You would need to delete the service and expose the deployment again for the target port values to be updated - this in case you missed one of my earlier responses.
