Can I remove cilium in managed kubernetes?

I’m using managed kubernetes. Doing ‘kubectl top pods –all-namespaces’ showed me that the cilium pods are taking significant amount of CPU. I did not install the cilium pods. They came with the managed cluster.

kube-system cilium-ct96b 54m 150Mi

kube-system cilium-fw9xd 172m 204Mi

kube-system cilium-jsldl 57m 167Mi

kube-system cilium-n2xbl 53m 151Mi

My questions are:

  1. What do the cilium pods do?
  2. Is it required for managed kubernetes? Can I remove them? How do I remove them?

Hi there,

Cilium is the component that provides the software defined network for the cluster. This is required for pods and internal components to communicate properly. You should not remove them. Any changed to the cilium configuration will be overwritten by the reconciliation process the next time it is kicked off.
