LoadBalancer and external IP

Hey guys, i need your help.

I am running a kubernetes cluster with one master and one node.

I am using two vms with public ips (internet accessible) for testing purpose.

Everything is working fine INTERNALLY.

I want to expose a service (postgres with port 5432) to the public.

I installed metallb, so that i can use type=LoadBalancer.

The external IP my exposed service became (from metallb) is something like 192.168.240.1. Can i redirect from the master public ip to this internal ip?

Thought of something with ip tables: Redirect from the external IP port 5432 to 192.168.240.1:5432.

Whats the way to go?

I just ordered another ip address which points to my server. How can i use this with metallb?

Would appreciate any help :slight_smile:

Thank you

Metallb allows you to specify a public ip address to use so you can set up the service to a specific address, you can request it by setting spec.LoadBalancerIP, just make sure metallb owns that public IP address.

Another thing to consider is that all these IPs must be within the same subnet for it to work. except you configure metallb in bgp mode
