Playgrounds
#1

If i create a nginx pod and expose it’s 80 port:

k run nginx --image nginx --expose --port 80

it coudn’t be achieved from the same namespace another pod via curl. On the v1.24 labs it works as expected (didnt’ try for v1.24 playground)

Hello @rostergek,

How did you verify the curl command? Can you share your screenshot?

Thanks,

I just tried and confirm it worked.
Create nginx-pod

trungtran@k8scommunity ~ % kubectl run nginx-pod --image=nginx --expose --port=80
service/nginx-pod created

Create another nginx in the same namespace

trungtran@k8scommunity ~ % kubectl run nginx-pod3 --image=nginx                     
pod/nginx-pod3 created

Try curl command

trungtran@k8scommunity ~ % kubectl exec -it nginx-pod 3 -- curl nginx-pod
