# 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).
|
