 ## Why does the kubelet manage the hosts file? {#why-does-kubelet-manage-the-hosts-file}
 
-The kubelet [manages](https://github.com/kubernetes/kubernetes/issues/14633) the
-`hosts` file for each container of the Pod to prevent Docker from
-[modifying](https://github.com/moby/moby/issues/17190) the file after the
-containers have already been started.
+The kubelet manages the
+`hosts` file for each container of the Pod to prevent the container runtime from
+modifying the file after the containers have already been started.
+Historically, Kubernetes always used Docker Engine as its container runtime, and Docker Engine would
+then modify the `/etc/hosts` file after each container had started.
+
+Current Kubernetes can use a variety of container runtimes; even so, the kubelet manages the
+hosts file within each container so that the outcome is as intended regardless of which
+container runtime you use.
 
 {{< caution >}}
 Avoid making manual changes to the hosts file inside a container.
