# Deploying headscale on Kubernetes
|
|
|
|
This directory contains [Kustomize](https://kustomize.io) 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

# 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
