wgmesh

WG Mesh

WG Mesh facilitates building a secure overlay network using the WireGuard protocol and a Kubernetes API.

Why??

WG Mesh is built for a variety of use-cases. WG Mesh can be used to provide virtual network connectivity between the pod/service networks of one or more clusters and non-local (other cloud, vpc, or on-prem) networks. For example, WG Mesh could provide secure routing between an on-prem network and an cloud hosted Kubernetes cluster.

Status

This project is under active development as of Dec 31, 2019. It should be considered as an early alpha. Basic functionality may work, but lots of useful features and testing are missing.

      --endpoint-addr string             endpoint address used by peers (default fqdn) (default "ubuntu-bionic")
  -h, --help                             help for agent
      --interface string                 network interface name for the wiregard interface. Use + suffix to auto-select the next available id (ex. wg+ for wg0,wg1... (default "wg+")
      --ips strings                      ip addresses which should be assigned to the local WireGuard interface

      --labels string                    apply kubernetes labels the local WireGuardPeer
      --name string                      name of the endpoint (default hostname) (default "ubuntu-bionic")
      --offer-routes strings             routes which this node will offer to peers
      --peer-selector string             select a subset of peers based on labels
      --port uint16                      port to bind the WireGuard service. 0 = random available port
      --registry-kubeconfig string       path to kubeconfig file for registry
      --registry-namespace string        kubernetes namespace
      --reuse-existing-interface         If --interface already exists, and is a compatible WireGuard device, reuse it.
      --wireguard-go-extra-args string   extra arguments to pass to the wireguard-go userspace driver
      --wireguard-go-path string         path to wireguard-go userspace driver

Global Flags:
      --debug   debug logging

Todo

• Finish MacOS/BSD support. Windows support???
• IPAM
• Populate routes via Kubernetes object references. Ex. node.PodCIDR
• More testing
• Template out Kubernetes deployment/ds and offer Kustomize or helm templates.
