We dont seem to need the wireguard key anymore, we generate a key on startup based on the new library and the users fetch it from /key. Clean up app.go and update docs
Deploying headscale on Kubernetes
This directory contains Kustomize templates that deploy headscale in various configurations.
These templates currently support Rancher k3s. Other clusters may require adaptation, especially around volume claims and ingress.
Commands below assume this directory is your current working directory.
Generate secrets and site configuration
Run ./init.bash to generate keys, passwords, and site configuration files.
Edit base/site/public.env, changing public-hostname to the public DNS name
that will be used for your headscale deployment.
Set public-proto to "https" if you're planning to use TLS & Let's Encrypt.
Configure DERP servers by editing base/site/derp.yaml if needed.
Add the image to the registry
You'll somehow need to get headscale:latest into your cluster image registry.
An easy way to do this with k3s:
- Reconfigure k3s to use docker instead of containerd (
k3s server --docker) docker build -t headscale:latest ..from here
Create the namespace
If it doesn't already exist, kubectl create ns headscale.
Deploy headscale
sqlite
kubectl -n headscale apply -k ./sqlite
postgres
kubectl -n headscale apply -k ./postgres
TLS & Let's Encrypt
Test a staging certificate with your configured DNS name and Let's Encrypt.
kubectl -n headscale apply -k ./staging-tls
Replace with a production certificate.
kubectl -n headscale apply -k ./production-tls
Static / custom TLS certificates
Only Let's Encrypt is supported. If you need other TLS settings, modify or patch the ingress.
Administration
Use the wrapper script to remotely operate headscale to perform administrative tasks like creating namespaces, authkeys, etc.
[c@nix-slate:~/Projects/headscale/k8s]$ ./headscale.bash
headscale is an open source implementation of the Tailscale control server
https://gitlab.com/juanfont/headscale

-h, --help help for headscale
-o, --output string Output format. Empty for human-readable, 'json' or 'json-line'
Use "headscale [command] --help" for more information about a command.
TODO / Ideas
- Interpolate
email:option to the ClusterIssuer from site configuration. This probably needs to be done with a transformer, kustomize vars don't seem to work. - Add kustomize examples for cloud-native ingress, load balancer
- CockroachDB for the backend
- DERP server deployment
- Tor hidden service
