Hello,
in this exercise I created in step 5 the "service again, but this time pass theLoadBalancertype. Check to see the status and note the external portsmentioned. The output will show theExternal-IPaspending. Unless a provider responds with a load balancer it willcontinue to show as pending".
In the step 6 I opened a browser on my local system and used the public IP of my master node and port32753, but the connection is refused and I am not able to see the Welcome Page of nginx server :(
Does anyone Know the reason?
Thanks for help

Alberto.

    Hello,
    attached the snaphot of my terminal (putty connected to the master node).
    If I use the ephemeral IP of one worker node, I see the welcome page in html format, but if test from my local machine ( with an external browser) to an ephimeral IP of the pod or to the load balancer Cluster IP, the connection fails.

    Thx and regards,

    A.

    Hi @albtau81,

    It seems you were trying to use the node port value 32753 from the lab guide. You are expected to use the node port value from your own cluster, which is displayed on step 5 by the kubectl get svc command. Please use the correct node port value to validate the access from the browser.

    Regards,

    Hi @serewicz ,
    I tested the internal service IP ( Load Balancer) and it works from within the remote node.Just if I test the connection to nginx server from my local machine, it goes in timeout with any browser ( I also disabled my enterprise firewall to check...).
    Hi@chrispokorni,
    yes i used the node port values 80:31974/TCP ( displayed by kubectl get svc command) but the connection goes in timeout..:(

    Regards,
    Alberto.
