I’m new to kubernetes and managed to set up a small cluster using Calico as the networking component.
I’m trying out some examples using a LoadBalancer Service. I’m trying to understand how kubernetes together with Calico is allocating the IP-address when creating the resource.
I read that you should use the serviceExternalIPs to put the CIDRs you want to be announced using BGP.
But I don’t find any information in the documentation what CIDRs is used when creating a LoadBalancer. It does get an IP but not the one from serviceExternalIPs CIDRS. Does Calico support allocating IPs for services? Or do I have to do a manual setup of the external IP when creating the LoadBalancer?
