I have a Kubernetes cluster with two networks, a 1 Gbit/s management network and a 100 Gbit/s data network. I am trying to use cilium as my CNI, but I find that my bandwidth is limited to 1 Gbit/s so presumably cilium is using the management network rather than the data network. How do I persuade cilium to use the 100 Gbit/s network ?
I am using cilium version 1.11.6 and Kubernetes version 1.22.4 .
When I asked this on StackOverflow https://stackoverflow.com/questions/72866983/how-do-i-configure-cilium-cni-to-use-my-100-gbit-s-interface , I got an answer to try specifying --apiserver-advertise-address= for the 100Gb interface on the kubeadm init command. I tried this but this did not work; the cluster started but used the 1 Gbit/s interface for data traffic. I also tried --apiserver-advertise-address= on the kubeadm join commands but got a message indicating that --control-plane was also necessary.
StackOverflow is the wrong forum for this question so I am trying here instead.
