I have been following the instructions so far and have come to the point where I have setup the worker nodes. I realized that on the first controller node kube-apiserver is not starting because the port 6443 is in use by Nginx
On the second controller kube-apiserver starts without any issue and the port 6443 is used by kube-apiserver.
netstat -lutpn | grep 6443
tcp6 0 0 :::6443 :::* LISTEN 1153/kube-apiserver
Not sure where the mistake was made. I went back and checked the config files and everything seems to be in order. If I stop the nginx server on the first node then kube-api server starts but then when I try to start nginx it gives me an error.
Appreciate any help that I can get in this matter.
