# 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
