Description:

* **all** - listing of all cluster nodes in the format specified in the example;
* **kube\_ingress -** Ingress nodes (there can be more than one);
* **kube\_vpn -** VPN server;
* **kube\_control\_plane -** master nodes (servers) of the cluster;
* **etcd -** nodes with the etcd service;
* **kube\_vpn\_clients -** worker nodes that will be connected to the VPN network;
* **kube\_node -** nodes that will be part of the cluster;
* **dekube -** groups of nodes that will be included in a single VPN network (do not edit);
* **k8s\_cluster -** groups of nodes that will be in the Kubernetes cluster (do not edit).
