# headscale will look for a configuration file named `config.yaml` (or `config.json`) in the following order:
#
# - `/etc/headscale`
# - `~/.headscale`
# - current working directory
# The url clients will connect to.
# Typically this will be a domain like:
#
# https://myheadscale.example.com:443
#
server_url: https://headscale.jakehoward.tech:443
# Address to listen to / bind to on the server
#
# For production:
# listen_addr: 0.0.0.0:8080

# to keep this endpoint private to your internal
# network
#
metrics_listen_addr: 127.0.0.1:9090
# Address to listen for gRPC.
# gRPC is used for controlling a headscale server
# remotely with the CLI
# Note: Remote access _only_ works if you have
# valid certificates.
#
# For production:

# DERP is a relay system that Tailscale uses when a direct

# https://tailscale.com/blog/how-tailscale-works/#encrypted-tcp-relays-derp
#
# headscale needs a list of DERP servers that can be presented
# to the clients.

# If enabled, runs the embedded DERP server and merges it into the rest of the DERP config
# The Headscale server_url defined above MUST be using https, DERP requires TLS to be in place

# Region ID to use for the embedded DERP server.
# The local DERP prevails if the region ID collides with other region ID coming from
# the regular DERP config.
region_id: 999
# Region code and name are displayed in the Tailscale UI to identify a DERP region

region_name: Headscale Embedded DERP
# Listens over UDP at the configured address for STUN connections - to help with NAT traversal.
# When the embedded DERP server is enabled stun_listen_addr MUST be defined.

### TLS configuration
#
## Let's encrypt / ACME
#
# headscale supports automatically requesting and setting up
# TLS for a domain with Let's Encrypt.
#
# URL to ACME directory
acme_url: https://acme-v02.api.letsencrypt.org/directory
# Email to register with ACME provider
acme_email: ""
# Domain name to request a TLS certificate for:

# letsencrypt
# For production:
tls_letsencrypt_cache_dir: /var/lib/headscale/cache
# Type of ACME challenge to use, currently supported types:
# HTTP-01 or TLS-ALPN-01
# See [docs/tls.md](docs/tls.md) for more information
tls_letsencrypt_challenge_type: HTTP-01
# When HTTP-01 challenge is chosen, letsencrypt must set up a
# verification endpoint, and it will be listening on:
# :http = port 80
tls_letsencrypt_listen: :http
## Use already defined certificates:
tls_cert_path: ""
tls_key_path: ""
log:
# Output formatting for logs: text or json
format: text

# Path to a file containg ACL policies.
# ACLs can be defined as YAML or HUJSON.

## DNS
#
# headscale supports Tailscale's DNS configuration and MagicDNS.
# Please have a look to their KB to better understand the concepts:

# nameservers:

# Whether to use [MagicDNS](https://tailscale.com/kb/1081/magicdns/).
# Only works if there is at least a nameserver defined.
magic_dns: false
# Defines the base domain to create the hostnames for MagicDNS.

# Logtail configuration
# Logtail is Tailscales logging and auditing infrastructure, it allows the control panel

logtail:
# Enable logtail for this headscales clients.
# As there is currently no support for overriding the log server in headscale, this is
# disabled by default. Enabling this will make your clients send logs to Tailscale Inc.
enabled: false
# Enabling this option makes devices prefer a random port for WireGuard traffic over the

# firewall devices. See https://tailscale.com/kb/1181/firewalls/ for more information.
