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.
For e.g. earlier Docker used to [modify](https://github.com/moby/moby/issues/17190) the `hosts` file after the containers start.
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.
