Who assign ClusterIP to service in kubernetes, could it be disabled?

I'm not sure which component in kubernetes do such job. Maybe kube-api-server or kube-controller-manager, since they both has a parameter named: "service-cluster-ip-range".

And I wonder to know if the assignment could be disable?

Thanks

Solution

  • After some research, finally I found the cluster ip is assigned by kube-api-server: it assign the validate cluster ip before stored the object to etcd!

    See the link: https://pkg.go.dev/k8s.io/kubernetes/pkg/registry/core/service@v1.22.1

    and you also can found related code in the kubernetes repository on github.

    So I guess it cannot be disabled : )
