 ## Overview

 Tailscale is [a modern VPN](https://tailscale.com/) built on top of [Wireguard](https://www.wireguard.com/).

 ## Roadmap 🤷

 Suggestions/PRs welcomed!

-## Running it

-1. Download the Headscale binary https://github.com/juanfont/headscale/releases, and place it somewhere in your PATH or use the docker container
+## Running headscale

-   ```shell
-   docker pull headscale/headscale:x.x.x
-   ```
+Please have a look at the documentation under [`docs/`](docs/).

-   <!--
-    or
-    ```shell
-    docker pull ghrc.io/juanfont/headscale:x.x.x
-    ``` -->
-
-2. (Optional, you can also use SQLite) Get yourself a PostgreSQL DB running
-
-   ```shell
-   docker run --name headscale -e POSTGRES_DB=headscale -e \
-     POSTGRES_USER=foo -e POSTGRES_PASSWORD=bar -p 5432:5432 -d postgres
-   ```
-
-3. Set some stuff up (headscale Wireguard keys & the config.json file)
-
-   ```shell
-   wg genkey > private.key
-   wg pubkey < private.key > public.key  # not needed
-
-   # Postgres
-   cp config.json.postgres.example config.json
-   # or
-   # SQLite
-   cp config.json.sqlite.example config.json
-   ```
-
-4. Create a namespace (a namespace is a 'tailnet', a group of Tailscale nodes that can talk to each other)
-
-   ```shell
-   headscale namespaces create myfirstnamespace
-   ```
-
-   or docker:
-
-   the db.sqlite mount is only needed if you use sqlite
-
-   ```shell
-   touch db.sqlite
-   docker run -v $(pwd)/private.key:/private.key -v $(pwd)/config.json:/config.json -v $(pwd)/derp.yaml:/derp.yaml -v $(pwd)/db.sqlite:/db.sqlite -p 127.0.0.1:8080:8080 headscale/headscale:x.x.x headscale namespaces create myfirstnamespace
-   ```
-
-   or if your server is already running in docker:
-
-   ```shell
-   docker exec <container_name> headscale create myfirstnamespace
-   ```
-
-5. Run the server
-
-   ```shell
-   headscale serve
-   ```
-
-   or docker:
-
-   the db.sqlite mount is only needed if you use sqlite
-
-   ```shell
-   docker run -v $(pwd)/private.key:/private.key -v $(pwd)/config.json:/config.json -v $(pwd)/derp.yaml:/derp.yaml -v $(pwd)/db.sqlite:/db.sqlite -p 127.0.0.1:8080:8080 headscale/headscale:x.x.x headscale serve
-   ```
-
-6. If you used tailscale.com before in your nodes, make sure you clear the tailscald data folder
-
-   ```shell
-   systemctl stop tailscaled
-   rm -fr /var/lib/tailscale
-   systemctl start tailscaled
-   ```
-
-7. Add your first machine
-
-   ```shell
-   tailscale up --login-server YOUR_HEADSCALE_URL
-   ```
-
-8. Navigate to the URL you will get with `tailscale up`, where you'll find your machine key.
-
-9. In the server, register your machine to a namespace with the CLI
-   ```shell
-   headscale -n myfirstnamespace nodes register YOURMACHINEKEY
-   ```
-   or docker:
-   ```shell
-   docker run -v $(pwd)/private.key:/private.key -v $(pwd)/config.json:/config.json -v $(pwd)/derp.yaml:/derp.yaml headscale/headscale:x.x.x headscale -n myfirstnamespace nodes register YOURMACHINEKEY
-   ```
-   or if your server is already running in docker:
-   ```shell
-   docker exec <container_name> headscale -n myfirstnamespace nodes register YOURMACHINEKEY
-   ```
-
-Alternatively, you can use Auth Keys to register your machines:
-
-1. Create an authkey
-
-   ```shell
-   headscale -n myfirstnamespace preauthkeys create --reusable --expiration 24h
-   ```
-
-   or docker:
-
-   ```shell
-   docker run -v $(pwd)/private.key:/private.key -v $(pwd)/config.json:/config.json -v$(pwd)/derp.yaml:/derp.yaml -v $(pwd)/db.sqlite:/db.sqlite headscale/headscale:x.x.x headscale -n myfirstnamespace preauthkeys create --reusable --expiration 24h
-   ```
-
-   or if your server is already running in docker:
-
-   ```shell
-   docker exec <container_name> headscale -n myfirstnamespace preauthkeys create --reusable --expiration 24h
-   ```
-
-2. Use the authkey from your machine to register it
-   ```shell
-   tailscale up --login-server YOUR_HEADSCALE_URL --authkey YOURAUTHKEY
-   ```
-
-If you create an authkey with the `--ephemeral` flag, that key will create ephemeral nodes. This implies that `--reusable` is true.
-
-Please bear in mind that all the commands from headscale support adding `-o json` or `-o json-line` to get a nicely JSON-formatted output.
-
-## Configuration reference
-
-Headscale's configuration file is named `config.json` or `config.yaml`. Headscale will look for it in `/etc/headscale`, `~/.headscale` and finally the directory from where the Headscale binary is executed.
-
-```
-    "server_url": "http://192.168.1.12:8080",
-    "listen_addr": "0.0.0.0:8080",
-    "ip_prefix": "100.64.0.0/10"
-```
-
-`server_url` is the external URL via which Headscale is reachable. `listen_addr` is the IP address and port the Headscale program should listen on. `ip_prefix` is the IP prefix (range) in which IP addresses for nodes will be allocated (default 100.64.0.0/10, e.g., 192.168.4.0/24, 10.0.0.0/8)
-
-```
-    "log_level": "debug"
-```
-
-`log_level` can be used to set the Log level for Headscale, it defaults to `debug`, and the available levels are: `trace`, `debug`, `info`, `warn` and `error`.
-
-```
-    "private_key_path": "private.key",
-```
-
-`private_key_path` is the path to the Wireguard private key. If the path is relative, it will be interpreted as relative to the directory the configuration file was read from.
-
-```
-    "derp_map_path": "derp.yaml",
-```
-
-`derp_map_path` is the path to the [DERP](https://pkg.go.dev/tailscale.com/derp) map file. If the path is relative, it will be interpreted as relative to the directory the configuration file was read from.
-
-```
-    "ephemeral_node_inactivity_timeout": "30m",
-```
-
-`ephemeral_node_inactivity_timeout` is the timeout after which inactive ephemeral node records will be deleted from the database. The default is 30 minutes. This value must be higher than 65 seconds (the keepalive timeout for the HTTP long poll is 60 seconds, plus a few seconds to avoid race conditions).
-
-```
-    "db_host": "localhost",
-    "db_port": 5432,
-    "db_name": "headscale",
-    "db_user": "foo",
-    "db_pass": "bar",
-```
-
-The fields starting with `db_` are used for the PostgreSQL connection information.
-
-### Running the service via TLS (optional)
-
-```
-    "tls_cert_path": ""
-    "tls_key_path": ""
-```
-
-Headscale can be configured to expose its web service via TLS. To configure the certificate and key file manually, set the `tls_cert_path` and `tls_cert_path` configuration parameters. If the path is relative, it will be interpreted as relative to the directory the configuration file was read from.
-
-```
-    "tls_letsencrypt_hostname": "",
-    "tls_letsencrypt_listen": ":http",
-    "tls_letsencrypt_cache_dir": ".cache",
-    "tls_letsencrypt_challenge_type": "HTTP-01",
-```
-
-To get a certificate automatically via [Let's Encrypt](https://letsencrypt.org/), set `tls_letsencrypt_hostname` to the desired certificate hostname. This name must resolve to the IP address(es) Headscale is reachable on (i.e., it must correspond to the `server_url` configuration parameter). The certificate and Let's Encrypt account credentials will be stored in the directory configured in `tls_letsencrypt_cache_dir`. If the path is relative, it will be interpreted as relative to the directory the configuration file was read from. The certificate will automatically be renewed as needed.
-
-#### Challenge type HTTP-01
-
-The default challenge type `HTTP-01` requires that Headscale is reachable on port 80 for the Let's Encrypt automated validation, in addition to whatever port is configured in `listen_addr`. By default, Headscale listens on port 80 on all local IPs for Let's Encrypt automated validation.
-
-If you need to change the ip and/or port used by Headscale for the Let's Encrypt validation process, set `tls_letsencrypt_listen` to the appropriate value. This can be handy if you are running Headscale as a non-root user (or can't run `setcap`). Keep in mind, however, that Let's Encrypt will _only_ connect to port 80 for the validation callback, so if you change `tls_letsencrypt_listen` you will also need to configure something else (e.g. a firewall rule) to forward the traffic from port 80 to the ip:port combination specified in `tls_letsencrypt_listen`.
-
-#### Challenge type TLS-ALPN-01
-
-Alternatively, `tls_letsencrypt_challenge_type` can be set to `TLS-ALPN-01`. In this configuration, Headscale listens on the ip:port combination defined in `listen_addr`. Let's Encrypt will _only_ connect to port 443 for the validation callback, so if `listen_addr` is not set to port 443, something else (e.g. a firewall rule) will be required to forward the traffic from port 443 to the ip:port combination specified in `listen_addr`.
-
-### Policy ACLs
-
-Headscale implements the same policy ACLs as Tailscale.com, adapted to the self-hosted environment.
-
-For instance, instead of referring to users when defining groups you must
-use namespaces (which are the equivalent to user/logins in Tailscale.com).
-
-Please check https://tailscale.com/kb/1018/acls/, and `./tests/acls/` in this repo for working examples.
-
-### Apple devices
-
-An endpoint with information on how to connect your Apple devices (currently macOS only) is available at `/apple` on your running instance.

+# Configuration reference
+
+Headscale will look for a configuration file named `config.yaml` (or `config.json`) in the following order:
+
+- `/etc/headscale`
+- `~/.headscale`
+- current working directory
+
+```yaml
+server_url: http://headscale.mydomain.net
+listen_addr: 0.0.0.0:8080
+ip_prefix: 100.64.0.0/10
+disable_check_updates: false
+```
+
+`server_url` is the external URL via which Headscale is reachable. `listen_addr` is the IP address and port the Headscale program should listen on. `ip_prefix` is the IP prefix (range) in which IP addresses for nodes will be allocated (default 100.64.0.0/10, e.g., 192.168.4.0/24, 10.0.0.0/8). `disable_check_updates` disables the automatic check for updates.
+
+```yaml
+log_level: debug
+```
+
+`log_level` can be used to set the Log level for Headscale, it defaults to `debug`, and the available levels are: `trace`, `debug`, `info`, `warn` and `error`.
+
+```yaml
+private_key_path: private.key
+```
+
+`private_key_path` is the path to the Wireguard private key. If the path is relative, it will be interpreted as relative to the directory the configuration file was read from.
+
+```yaml
+derp_map_path: derp.yaml
+```
+
+`derp_map_path` is the path to the [DERP](https://pkg.go.dev/tailscale.com/derp) map file. If the path is relative, it will be interpreted as relative to the directory the configuration file was read from.
+
+```yaml
+ephemeral_node_inactivity_timeout": "30m"
+```
+
+`ephemeral_node_inactivity_timeout` is the timeout after which inactive ephemeral node records will be deleted from the database. The default is 30 minutes. This value must be higher than 65 seconds (the keepalive timeout for the HTTP long poll is 60 seconds, plus a few seconds to avoid race conditions).
+
+PostgresSQL
+
+```yaml
+db_host: localhost
+db_port: 5432
+db_name: headscale
+db_user: foo
+db_pass: bar
+```
+
+SQLite
+
+```yaml
+db_type: sqlite3
+db_path: db.sqlite
+```
+
+The fields starting with `db_` are used for the DB connection information.
+
+### TLS configuration
+
+Please check [`TLS.md`](TLS.md).
+
+### DNS configuration
+
+Please refer to [`DNS.md`](DNS.md).
+
+### Policy ACLs
+
+Headscale implements the same policy ACLs as Tailscale.com, adapted to the self-hosted environment.
+
+For instance, instead of referring to users when defining groups you must
+use namespaces (which are the equivalent to user/logins in Tailscale.com).
+
+Please check https://tailscale.com/kb/1018/acls/, and `./tests/acls/` in this repo for working examples.
+
+### Apple devices
+
+An endpoint with information on how to connect your Apple devices (currently macOS only) is available at `/apple` on your running instance.

+# DNS in headscale
+
+headscale supports Tailscale's DNS configuration and MagicDNS. Please have a look to their KB to better understand what this means:
+
+- https://tailscale.com/kb/1054/dns/
+- https://tailscale.com/kb/1081/magicdns/
+- https://tailscale.com/blog/2021-09-private-dns-with-magicdns/
+
+Long story short, you can define the DNS servers you want to use in your tailnets, activate MagicDNS (so you don't have to remember the IP addresses of your nodes), define search domains, as well as predefined hosts. headscale will inject that settings into your nodes.
+
+## Configuration reference
+
+The setup is done via the `config.yaml` file, under the `dns_config` key.
+
+```yaml
+server_url: http://127.0.0.1:8001
+listen_addr: 0.0.0.0:8001
+private_key_path: private.key
+dns_config:
+  nameservers:
+    - 1.1.1.1
+    - 8.8.8.8
+  restricted_nameservers:
+    foo.bar.com:
+      - 1.1.1.1
+    darp.headscale.net:
+      - 1.1.1.1
+      - 8.8.8.8
+  domains: []
+  magic_dns: true
+  base_domain: example.com
+```
+
+- `nameservers`: The list of DNS servers to use.
+- `domains`: Search domains to inject.
+- `magic_dns`: Whether to use [MagicDNS](https://tailscale.com/kb/1081/magicdns/). Only works if there is at least a nameserver defined.
+- `base_domain`: Defines the base domain to create the hostnames for MagicDNS. `base_domain` must be a FQDNs, without the trailing dot. The FQDN of the hosts will be `hostname.namespace.base_domain` (e.g., _myhost.mynamespace.example.com_).
+- `restricted_nameservers`: Split DNS (see https://tailscale.com/kb/1054/dns/), list of search domains and the DNS to query for each one.

+# Running headscale
+
+1. Download the headscale binary https://github.com/juanfont/headscale/releases, and place it somewhere in your $PATH or use the docker container
+
+   ```shell
+   docker pull headscale/headscale:x.x.x
+   ```
+
+   <!--
+    or
+    ```shell
+    docker pull ghrc.io/juanfont/headscale:x.x.x
+    ``` -->
+
+2. (Optional, you can also use SQLite) Get yourself a PostgreSQL DB running
+
+   ```shell
+   docker run --name headscale \
+     -e POSTGRES_DB=headscale
+     -e POSTGRES_USER=foo \
+     -e POSTGRES_PASSWORD=bar \
+     -p 5432:5432 \
+     -d postgres
+   ```
+
+3. Create a WireGuard private key and headscale configuration
+
+   ```shell
+   wg genkey > private.key
+
+   cp config.yaml.example config.yaml
+   ```
+
+4. Create a namespace
+
+   ```shell
+   headscale namespaces create myfirstnamespace
+   ```
+
+   or docker:
+
+   the db.sqlite mount is only needed if you use sqlite
+
+   ```shell
+   touch db.sqlite
+   docker run \
+     -v $(pwd)/private.key:/private.key \
+     -v $(pwd)/config.json:/config.json \
+     -v $(pwd)/derp.yaml:/derp.yaml \
+     -v $(pwd)/db.sqlite:/db.sqlite \
+     -p 127.0.0.1:8080:8080 \
+     headscale/headscale:x.x.x \
+     headscale namespaces create myfirstnamespace
+   ```
+
+   or if your server is already running in docker:
+
+   ```shell
+   docker exec <container_name> headscale create myfirstnamespace
+   ```
+
+5. Run the server
+
+   ```shell
+   headscale serve
+   ```
+
+   or docker:
+
+   the db.sqlite mount is only needed if you use sqlite
+
+   ```shell
+   docker run \
+     -v $(pwd)/private.key:/private.key \
+     -v $(pwd)/config.json:/config.json \
+     -v $(pwd)/derp.yaml:/derp.yaml \
+     -v $(pwd)/db.sqlite:/db.sqlite \
+     -p 127.0.0.1:8080:8080 \
+     headscale/headscale:x.x.x headscale serve
+   ```
+
+6. If you used tailscale.com before in your nodes, make sure you clear the tailscaled data folder
+
+   ```shell
+   systemctl stop tailscaled
+   rm -fr /var/lib/tailscale
+   systemctl start tailscaled
+   ```
+
+7. Add your first machine
+
+   ```shell
+   tailscale up --login-server YOUR_HEADSCALE_URL
+   ```
+
+8. Navigate to the URL you will get with `tailscale up`, where you'll find your machine key.
+
+9. In the server, register your machine to a namespace with the CLI
+   ```shell
+   headscale -n myfirstnamespace nodes register YOURMACHINEKEY
+   ```
+   or docker:
+   ```shell
+   docker run \
+     -v $(pwd)/private.key:/private.key \
+     -v $(pwd)/config.json:/config.json \
+     -v $(pwd)/derp.yaml:/derp.yaml \
+     headscale/headscale:x.x.x \
+     headscale -n myfirstnamespace nodes register YOURMACHINEKEY
+   ```
+   or if your server is already running in docker:
+   ```shell
+   docker exec <container_name> headscale -n myfirstnamespace nodes register YOURMACHINEKEY
+   ```
+
+Alternatively, you can use Auth Keys to register your machines:
+
+1. Create an authkey
+
+   ```shell
+   headscale -n myfirstnamespace preauthkeys create --reusable --expiration 24h
+   ```
+
+   or docker:
+
+   ```shell
+   docker run \
+     -v $(pwd)/private.key:/private.key \
+     -v $(pwd)/config.json:/config.json \
+     -v$(pwd)/derp.yaml:/derp.yaml \
+     -v $(pwd)/db.sqlite:/db.sqlite \
+     headscale/headscale:x.x.x \
+     headscale -n myfirstnamespace preauthkeys create --reusable --expiration 24h
+   ```
+
+   or if your server is already running in docker:
+
+   ```shell
+   docker exec <container_name> headscale -n myfirstnamespace preauthkeys create --reusable --expiration 24h
+   ```
+
+2. Use the authkey from your machine to register it
+   ```shell
+   tailscale up --login-server YOUR_HEADSCALE_URL --authkey YOURAUTHKEY
+   ```
+
+If you create an authkey with the `--ephemeral` flag, that key will create ephemeral nodes. This implies that `--reusable` is true.
+
+Please bear in mind that all headscale commands support adding `-o json` or `-o json-line` to get nicely JSON-formatted output.

+# Running the service via TLS (optional)
+
+```yaml
+tls_letsencrypt_hostname: ""
+tls_letsencrypt_listen: ":http"
+tls_letsencrypt_cache_dir: ".cache"
+tls_letsencrypt_challenge_type: HTTP-01
+```
+
+To get a certificate automatically via [Let's Encrypt](https://letsencrypt.org/), set `tls_letsencrypt_hostname` to the desired certificate hostname. This name must resolve to the IP address(es) headscale is reachable on (i.e., it must correspond to the `server_url` configuration parameter). The certificate and Let's Encrypt account credentials will be stored in the directory configured in `tls_letsencrypt_cache_dir`. If the path is relative, it will be interpreted as relative to the directory the configuration file was read from. The certificate will automatically be renewed as needed.
+
+```yaml
+tls_cert_path: ""
+tls_key_path: ""
+```
+
+headscale can also be configured to expose its web service via TLS. To configure the certificate and key file manually, set the `tls_cert_path` and `tls_cert_path` configuration parameters. If the path is relative, it will be interpreted as relative to the directory the configuration file was read from.
+
+## Challenge type HTTP-01
+
+The default challenge type `HTTP-01` requires that headscale is reachable on port 80 for the Let's Encrypt automated validation, in addition to whatever port is configured in `listen_addr`. By default, headscale listens on port 80 on all local IPs for Let's Encrypt automated validation.
+
+If you need to change the ip and/or port used by headscale for the Let's Encrypt validation process, set `tls_letsencrypt_listen` to the appropriate value. This can be handy if you are running headscale as a non-root user (or can't run `setcap`). Keep in mind, however, that Let's Encrypt will _only_ connect to port 80 for the validation callback, so if you change `tls_letsencrypt_listen` you will also need to configure something else (e.g. a firewall rule) to forward the traffic from port 80 to the ip:port combination specified in `tls_letsencrypt_listen`.
+
+## Challenge type TLS-ALPN-01
+
+Alternatively, `tls_letsencrypt_challenge_type` can be set to `TLS-ALPN-01`. In this configuration, headscale listens on the ip:port combination defined in `listen_addr`. Let's Encrypt will _only_ connect to port 443 for the validation callback, so if `listen_addr` is not set to port 443, something else (e.g. a firewall rule) will be required to forward the traffic from port 443 to the ip:port combination specified in `listen_addr`.
