# headscale-operator
|
||
|
||
A Kubernetes Operator to instanciate and control headscale instances.
|
||
|
||
## Description
|
||
|
||
With _headscale-operator_ you can instanciate multiple [headscale](https://github.com/juanfont/headscale) servers for multiple purpose.
|
||
|
||
_headscale-operator_ let you manage [_namespaces_](https://github.com/juanfont/headscale/blob/main/docs/glossary.md) and _preauthkeys_.
|
||
|
||
## Getting Started
|
||
|
||
You’ll need a Kubernetes cluster to run against. You can use [KIND](https://sigs.k8s.io/kind) to get a local cluster for testing, or run against a remote cluster.
|
||
**Note:** Your controller will automatically use the current context in your kubeconfig file (i.e. whatever cluster `kubectl cluster-info` shows).
|
||
|
||
### Running on the cluster
|
||
|
||
1. Install Instances of Custom Resources:
|
||
|
||
```sh
|
||
kubectl apply -f config/samples/
|
||
```
|
||
|
||
1. Build and push your image to the location specified by `IMG`:
|
||
|
||
```sh
|
||
make docker-build docker-push IMG=<some-registry>/headscale-operator:tag
|
||
```
|
||
|
||
1. Deploy the controller to the cluster with the image specified by `IMG`:
|
||
|
||
```sh
|
||
make deploy IMG=<some-registry>/headscale-operator:tag
|
||
```
|
||
|
||
### Uninstall CRDs
|
||
|
||
To delete the CRDs from the cluster:
|
||
|
||
```sh
|
||
make uninstall
|
||
```
|
||
|
||
### Undeploy controller
|
||
|
||
UnDeploy the controller to the cluster:
|
||
|
||
```sh
|
||
make undeploy
|
||
```
|
||
|
||
### How it works
|
||
|
||
This project aims to follow the Kubernetes [Operator pattern](https://kubernetes.io/docs/concepts/extend-kubernetes/operator/)
|
||
|
||
It uses [Controllers](https://kubernetes.io/docs/concepts/architecture/controller/)
|
||
which provides a reconcile function responsible for synchronizing resources untile the desired state is reached on the cluster
|
||
|
||
### Test It Out
|
||
|
||
1. Install the CRDs into the cluster:
|
||
|
||
```sh
|
||
make install
|
||
```
|
||
|
||
1. Run your controller (this will run in the foreground, so switch to a new terminal if you want to leave it running):
|
||
|
||
```sh
|
||
make run
|
||
```
|
||
|
||
**NOTE:** You can also run this in one step by running: `make install run`
|
||
|
||
### Modifying the API definitions
|
||
|
||
If you are editing the API definitions, generate the manifests such as CRs or CRDs using:
|
||
|
||
```sh
|
||
make manifests
|
||
```
|
||
|
||
**NOTE:** Run `make --help` for more information on all potential `make` targets
