## Verifying Artifacts

We sign our artifacts using this [key][signing_key]:

```

 * <p>This is pretty much a placeholder for something more descriptive.

It discovers plugins by monitoring inotify events under the directory returned by
kubelet.getPluginsDir(). We will refer to this directory as PluginsDir.

Plugins are expected to implement the gRPC registration service specified in
pkg/kubelet/apis/pluginregistration/v*/api.proto.

## Plugin Discovery

The pluginwatcher service will discover plugins in the PluginDir when they
