# kg
`kg` is the Kilo agent that runs on every Kubernetes node in a Kilo mesh.
It performs several key functions, including:
* adding the node to the Kilo mesh;
* installing CNI configuration on the node;
* configuring the WireGuard network interface; and
* maintaining routing table entries and iptables rules.
`kg` is typically installed on all nodes of a Kubernetes cluster using a DaemonSet.
Example manifests can be found [in the manifests directory](https://github.com/squat/kilo/tree/master/manifests).
## Usage
The behavior of `kg` can be configured using the command line flags listed below.

When should Kilo encapsulate packets within a location? Possible values: never, crosssubnet, always (default "always")
-hostname string
Hostname of the node on which this process is running.
-interface string
