-# Deploying headscale on Kubernetes
-
-**Note:** This is contributed by the community and not verified by the headscale authors.
-
-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
-
-https://github.com/juanfont/headscale
-
-Usage:
-  headscale [command]
-
-Available Commands:
-  help        Help about any command
-  namespace   Manage the namespaces of headscale
-  node        Manage the nodes of headscale
-  preauthkey  Handle the preauthkeys in headscale
-  routes      Manage the routes of headscale
-  serve       Launches the headscale server
-  version     Print the version.
-
-Flags:
-  -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
