The installation went through well. But when I am doing `kubectl` sometimes it is getting connected and fetching details and sometimes or most of the time it is complaining `connection refused`

Hi Pradeep, you rock, I installed the k8s on rocky 9.1, it worked. Only thing to take care firewall-cmd does not come enabled. So u install first with sudo yum install firewalld
sudo systemctl enable firewalld –now. After which the step 4 can be executed. Since firewalld is not installed, same as can be skipped as well, as firewall in not installed and enabled. Else it was cakewalk…. Great… thanks a ton…
