7. Verify the shopping cart is exposing a web page.

I had to create firewall rule in the gcp instance to see shoppingcart webpage using externalip:30001

Hi,
When building a Kubernetes cluster in the cloud, it may require a firewall rule to enable traffic from/to outside of the cluster. A similar approach when working with VirtualBox or VMware is to enable all traffic to the VM instances.
Depending on the node's OS distribution, a firewall may also be enabled by default at the OS level, in which case it needs to be disabled - for the purpose of these labs, but not as best practice, and not recommended for prod.
Regards,
