No longer required if the minimum is beta2

CHANGELOG.md

@@ -1,3 +1,21 @@
+### 0.2.4 (August 24, 2024)
+- Removed ACL management from the integration since Headscale 0.23-beta2 now supports it natively.
+- Removed the `ACL_FILE` environment variable since it's no longer needed.
+- Introduce a `COOKIE_SECURE=false` environment variable to disable HTTPS requirements for cookies.
+- Fixed a bug where removing Split DNS configurations would crash the UI.
+
+### 0.2.3 (August 23, 2024)
+- Change the minimum required version of Headscale to 0.23-beta2
+- Support the new API policy mode for Headscale 0.23-beta1
+- Switch to the new DNS configuration in Headscale 0.23-beta2 (fixes [#29](https://github.com/tale/headplane/issues/29))
+- If OIDC environment variables are defined, don't use configuration file values (fixes [#24](https://github.com/tale/headplane/issues/24))
+
+### 0.2.2 (August 2, 2024)
+- Added a proper Kubernetes integration which utilizes `shareProcessNamespace` for PIDs.
+- Added a new logger utility that shows categories, levels, and timestamps.
+- Reimplemented the integration system to be more resilient and log more information.
+- Fixed an issue where the /proc integration found `undefined` PIDs.
+
 ### 0.2.1 (July 7, 2024)
 - Added the ability to manage custom DNS records on your Tailnet.
 - ACL tags for machines are now able to be changed via the machine menu.

-## Automatic Configuration Reload
+## Deployment
-
-When the configuration file is changed, Headscale will need to be restarted to apply the changes.
-Similarly, when the ACL file is changed, Headscale will need to be sent a `SIGHUP` signal to reload the ACLs.
-Currently there are 2 integration providers that can do this for you:
-
-### Docker Integration
-
-To enable the Docker integration, set `HEADSCALE_INTEGRATION=docker` in the environment variables.
-Additionally, you'll need to pass in the `HEADSCALE_CONTAINER` environment variable.
-This should be either the name or ID of the Headscale container (you can retrieve this using `docker ps`).
-If the other integrations aren't setup, then Headplane will automatically disable the Docker integration.
-
-By default the integration will check for `/var/run/docker.sock`, however you can override this by
-setting the `DOCKER_SOCK` environment variable if you use a different configuration than the default.
-When setting `DOCKER_SOCK`, you'll need to include the protocol (e.g., `unix://` or `tcp://`).
-Headplane currently does not support the HTTPS protocol for the Docker socket.

-#### Example Docker Deployment
 
 Requirements:
-- Headscale 0.23 alpha or later

-
-### Native Linux Integration (Beta)
-
-The native integration for Linux relies on the `/proc` directory to locate the Headscale process.
-To enable it, set the `HEADSCALE_INTEGRATION=proc` value in the environment variables.
-Because of the way this integration works, it only supports automatically reloading ACLs.
-It's still very experimental and may not work in all environments.
-
-## Configuration Scenarios
-
-Since the configuration is fairly modular you can have a variety of different setups.
-This mostly applies to the Docker integration since the native integration isn't fully featured yet.
-Here are a few examples to inspire you and show you what can work and what can't:
-
-#### Full Integration
-Headscale runs in a container, Headplane can run in either a container or natively.
-Headplane is able to manage the configuration file and ACLs that Headscale uses.
-When changes happen, the Docker integration will automatically reload the configuration and ACLs.
-
-> Note that the full integration currently isn't possible if Headscale isn't running in a container.
-
-#### Configuration Only
-Headscale and Headplane can either run in containers or natively.
-Headplane is able to manage the configuration file and ACLs that Headscale uses.
-When changes are made, Headscale will need to be manually restarted to apply the changes.
-
-#### ACL Only
-Headscale and Headplane can either run in containers or natively.
-Headplane is able to manage the ACLs that Headscale uses.
-When changes are made, Headscale will need to be sent a `SIGHUP` to reload the ACLs.
-In this scenario, Headplane does not have access to the configuration file.
-
-#### Read-Only Configuration or ACLs
-If the configuration or ACLs are read-only, Headplane will not be able to manage them.
-Instead you'll only be able to view the configurations on the UI and need to edit them manually.
-
-#### No Integration
-If no integration is setup, Headplane will not be able to manage the configuration or ACLs.
-This is the simplest setup by far, however it also heavily reduces the capabilities of Headplane.

+## Kubernetes Integration
+
+The Kubernetes integration allows you to run Headplane and Headscale together
+in a cluster. It allows you to unlock full functionality such as automatic
+reloading of ACLs, DNS management, and Headscale configuration management.
+
+Currently there are a few limitations to the Kubernetes integration:
+- Headplane and Headscale need to run in the same Pod and share the same
+  process space for the integration to work correctly due to a limitation in
+  the Kubernetes API.
+
+- The only supported methods of deploying the integration are through a
+  `Deployment` or `Pod` (more coming soon). You can still get around this with
+  the `HEADSCALE_INTEGRATION_UNSTRICT` variable, but it's not recommended.
+
+- The integration will assume that the Headscale container will always restart
+  because the integration relies on a system call that will exit the container.
+
+### Deployment
+
+In order to ensure Headplane can read Kubernetes resources, you'll need to
+grant additional RBAC permissions to the default `ServiceAccount` in the
+namespace. This can be done with the following:
+```yaml
+apiVersion: rbac.authorization.k8s.io/v1
+kind: Role
+metadata:
+  name: headplane-agent
+  namespace: default # Adjust namespace as needed
+rules:
+- apiGroups: ['']
+  resources: ['pods']
+  verbs: ['get', 'list']
+- apiGroups: ['apps']
+  resources: ['deployments']
+  verbs: ['get', 'list']
+---
+apiVersion: rbac.authorization.k8s.io/v1
+kind: RoleBinding
+metadata:
+  name: headplane-agent
+  namespace: default # Adjust namespace as needed
+roleRef:
+    apiGroup: rbac.authorization.k8s.io
+    kind: Role
+    name: headplane-agent
+subjects:
+- kind: ServiceAccount
+  name: default # If you use a different service account, change this
+  namespace: default # Adjust namespace as needed
+```
+
+Keep in mind you'll need to make `PersistentVolumeClaim`s for the data and that
+they need to be either `ReadWriteOnce` or `ReadWriteMany` depending on your
+topology. Additionally, you can abstract environment variables and configuration
+away into a `ConfigMap` or `Secret` for easier management.
+
+The important parts of this deployment are the `HEADSCALE_INTEGRATION` and
+`DEPLOYMENT_NAME` environment variables. The `HEADSCALE_INTEGRATION` variable
+should be set to `kubernetes` and the `POST_NAME` variable should be set

+set `HEADSCALE_INTEGRATION_UNSTRICT` to `true` to disable the strict checks.

+## Native Integration
+
+The Native integration allows you to run both Headplane and Headscale on
+bare-metal servers or virtual machines. This integration is best suited for
+environments where Docker or Kubernetes are not available or not desired.
+
+Currently the Native integration only supports automatic reloading of ACLs. It
+cannot handle configuration changes as killing the `headscale` process can lead
+to undefined behavior or the service not restarting.
+
+### Deployment
+
+Follow the instructions to install Headscale from the
+[Linux Installation Guide](https://headscale.net/running-headscale-linux/). As
+of now, Headplane requires Node.js 20 to be installed on the system. Once you
+are ready, clone the repository (`git clone https://github.com/tale/headplane`),
+install dependencies (`npm install`), build the project (`npm run build`), and
+start the server (`npm start`).
+
+> If you'd like, you can turn this into a `systemd` unit to manage the service.
+> I plan to provide packages and unit files to make this easier in the future.
+
+When running Headplane, you'll need to set environment variables to configure
+the application. The `HEADSCALE_INTEGRATION` variable should be set to `proc`.
+
+> For a breakdown of each configuration variable, please refer to the
+[Configuration](/docs/Configuration.md) guide.
