@@ -354,16 +354,6 @@ Here's a breakdown of what/why:
    API using this CA certificate.
 * `--authorization-mode=Webhook` authorizes requests to the Kubelet API by `POST`-ing
    a `SubjectAccessReview` to the API server.
-* `--cadvisor-port=0` disables cAdvisor from listening to `0.0.0.0:4194` by default.
-   cAdvisor will still be run inside of the kubelet and its API can be accessed at
-   `https://{node-ip}:10250/stats/`. If you want to enable cAdvisor to listen on a
-   wide-open port, run:
-
-   ```bash
-   sed -e "/cadvisor-port=0/d" -i /etc/systemd/system/kubelet.service.d/10-kubeadm.conf
-   systemctl daemon-reload
-   systemctl restart kubelet
-   ```
 * `--rotate-certificates` auto rotate the kubelet client certificates by requesting new
    certificates from the `kube-apiserver` when the certificate expiration approaches.
 * `--cert-dir`the directory where the TLS certs are located.
