Helm Charts

Notice: It works well with K3s. SSL cert is managed by cert-manager. You should edit the templates, if K8s is used to replace K3s.

# values.yaml
hostname: derp.example.com  # Your derper hostname
replicaCount: 1 # Replica count, Suggest 1

mesh_with: # Mesh with other derper, if empty mesh is disabled
pskKey: # Mesh PSK key, must be same with other derper, 64 hex string at least

ingressAnnotations: # Ingress annotations

  -c string
        config file path

  -certmode string
        mode for getting a cert. possible options: manual, letsencrypt (default "letsencrypt")
