Support and discussions

Currently the opeartor has only been tested on GKE; if you are facing any problems please open an issue or join our slack channel

Tested with

IBM Cloud Kubernetes Service
Google Kubernetes Engine
- requires spec.mtu: "1380"
DigitalOcean Kubernetes
- requires spec.serviceType: "NodePort". DigitalOcean LoadBalancer does not support UDP.
Amazon EKS
Azure Kubernetes Service

Architecture

Features

Uses userspace implementation of wireguard through wireguard-go
Automatic key generation
Automatic IP allocation
Does not need persistance. peer/server keys are stored as k8s secrets and loaded into the wireguard pod
Exposes a metrics endpoint by utilizing prometheus_wireguard_exporter

Example

server

apiVersion: vpn.example.com/v1alpha1
kind: Wireguard
metadata:
  name: "my-cool-vpn"
spec:
  mtu: "1380"

peer

apiVersion: vpn.example.com/v1alpha1
kind: WireguardPeer
metadata:
  name: peer1
spec:
  wireguardRef: "my-cool-vpn"

Peer configuration

Peer configuration can be retreived using the following command

command:

kubectl get wireguardpeer peer1 --template={{.status.config}} | bash

output:
