I work on K3S kuberentes cluster on ubuntu.
Local IP address 192.168.111.2
public IP address : 192.168.20.90
ip loadbalancer : 192.168.111.100
I build an Nginx with the k3sdomain.com domain on my K3S cluster.
I can access my k3sdomain.com from my machine and another computer in a local network, simply type k3sdomain.com through the browser, but I need to put my hostname On another /etc/hosts machine.
something like this:
192.168.111.100 k3sdomain.com
But it is so ridiculous if I have many clients and need to configure every client host, and how if they access through phone, etc.
I came up with how to build a DNS server and connect to my Nginx cluster, so I followed this https://ubuntu.com/server/docs/service-domain-name-service-dns instruction. I changed the nameserver IP address many times to make sure I put the correct IP. I switched to local IP:192.168.111.2, public: 192.168.20.90 or even my load balancer IP address, but it is not working.
Maybe I don't get the concept. But please let me know your thought.
is it normal if we can not ping our hostname or Ip load balancer from the local machine/localhost?
ping k3sdomain.com ping 192.168.111.100
it will not work, but I can ping from another machine
Thank you.
