# 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: http://127.0.0.1:8080
# Address to listen to / bind to on the server
#
# For production:
# listen_addr: 0.0.0.0:8080
listen_addr: 127.0.0.1:8080
# Address to listen to /metrics, you may want
# 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:
# grpc_listen_addr: 0.0.0.0:50443
grpc_listen_addr: 127.0.0.1:50443
# Allow the gRPC admin interface to run in INSECURE
# mode. This is not recommended as the traffic will
# be unencrypted. Only enable if you know what you
# are doing.
grpc_allow_insecure: false
# The Noise section includes specific configuration for the
# TS2021 Noise protocol

# The Noise private key is used to encrypt the
# traffic between headscale and Tailscale clients when
# using the new Noise-based protocol.

# List of IP prefixes to allocate tailaddresses from.
# Each prefix consists of either an IPv4 or IPv6 address,
# and the associated prefix length, delimited by a slash.
# It must be within IP ranges supported by the Tailscale
# client - i.e., subnets of 100.64.0.0/10 and fd7a:115c:a1e0::/48.
# See below:
# IPv6: https://github.com/tailscale/tailscale/blob/22ebb25e833264f58d7c3f534a8b166894a89536/net/tsaddr/tsaddr.go#LL81C52-L81C71

# Any other range is NOT supported, and it will cause unexpected issues.

# DERP is a relay system that Tailscale uses when a direct
# connection cannot be established.
# 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.
derp:
server:
# 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
enabled: false
# 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_code: "headscale"
region_name: "Headscale Embedded DERP"
# Listens over UDP at the configured address for STUN connections - to help with NAT traversal.

private_key_path: /var/lib/headscale/derp_server_private.key
# This flag can be used, so the DERP map entry for the embedded DERP server is not written automatically,
# it enables the creation of your very own DERP map entry using a locally available file with the parameter DERP.paths

### 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:
tls_letsencrypt_hostname: ""
# Path to store certificates and metadata needed by
# 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:
