wg-access-server - Helm Chart Repository

This repository contains the Helm Chart files for the wg-access-server project.

Installing the Chart

To install the chart with the release name wireguard:

$ helm install wireguard --repo https://freifunkMUC.github.io/wg-access-server-chart/ wg-access-server

The command deploys wg-access-server on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.

A wireguard private key needs to be set in order for the pod to start successfully. Use wg genkey and append --set wireguard.config.privateKey="<wg-private-key>" to the command above.

Per default persistence is disabled and devices will not persist. To enable persistence, set persistence.enabled.

Because IPv6 on Kubernetes is disabled by default in most clusters and can't be enabled on a per-pod basis, the default values.yaml disables it for the VPN as well. If you have a cluster with working IPv6, set config: {} in your values.yaml or specify a custom VPN-internal prefix under config.vpn.cidrv6.

If no admin password is set, the Chart generates a random one. You can retrieve it using kubectl get secret ... as prompted by helm after installing the Chart.

Uninstalling the Chart

To uninstall/delete the wireguard deployment:

$ helm delete wireguard

The command removes all the Kubernetes components associated with the chart and deletes the release.
