# 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.
