File config-example.yaml of Package headscale

---
# 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
noise:
  # The Noise private key is used to encrypt the
  # traffic between headscale and Tailscale clients when
  # using the new Noise-based protocol.
  private_key_path: /var/lib/headscale/noise_private.key

# 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
# IPv4: https://github.com/tailscale/tailscale/blob/22ebb25e833264f58d7c3f534a8b166894a89536/net/tsaddr/tsaddr.go#L33
# Any other range is NOT supported, and it will cause unexpected issues.
prefixes:
  v6: fd7a:115c:a1e0::/48
  v4: 100.64.0.0/10

# Strategy used for allocation of IPs to nodes, available options:
  # - sequential (default): assigns the next free IP from the previous given IP.
  # - random: assigns the next free IP from a pseudo-random IP generator (crypto/rand).
  allocation: sequential

# 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_id: 999

# Region code and name are displayed in the Tailscale UI to identify a DERP region
    region_code: "headscale"
    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.
    #
    # For more details on how this works, check this great article: https://tailscale.com/blog/how-tailscale-works/
    stun_listen_addr: "0.0.0.0:3478"

# Private key used to encrypt the traffic between headscale DERP
    # and Tailscale clients.
    # The private key file will be autogenerated if it's missing.
    #
    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
    # If you enable the DERP server and set this to false, it is required to add the DERP server to the DERP map using DERP.paths
    automatically_add_embedded_derp_region: true

# For better connection stability (especially when using an Exit-Node and DNS is not working),
    # it is possible to optionally add the public IPv4 and IPv6 address to the Derp-Map using:
    ipv4: 1.2.3.4
    ipv6: 2001:db8::1

# List of externally available DERP maps encoded in JSON

### 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
  level: info

## Policy
# headscale supports Tailscale's ACL policies.
# Please have a look to their KB to better
# understand the concepts: https://tailscale.com/kb/1018/acls/
policy:
  # The mode can be "file" or "database" that defines
  # where the ACL policies are stored and read from.
  mode: file
  # If the mode is set to "file", the path to a
  # HuJSON file containing ACL policies.
  path: ""

## DNS
#
# headscale supports Tailscale's DNS configuration and MagicDNS.
# Please have a look to their KB to better understand the concepts:
#
# - https://tailscale.com/kb/1054/dns/
# - https://tailscale.com/kb/1081/magicdns/
# - https://tailscale.com/blog/2021-09-private-dns-with-magicdns/
#
# Please note that for the DNS configuration to have any effect,
# clients must have the `--accept-dns=true` option enabled. This is the
# default for the Tailscale client. This option is enabled by default
# in the Tailscale client.
#
# Setting _any_ of the configuration and `--accept-dns=true` on the
# clients will integrate with the DNS manager on the client or
# overwrite /etc/resolv.conf.
# https://tailscale.com/kb/1235/resolv-conf
#
# If you want stop Headscale from managing the DNS configuration
# all the fields under `dns` should be set to empty values.
dns:
  # Whether to use [MagicDNS](https://tailscale.com/kb/1081/magicdns/).
  # Only works if there is at least a nameserver defined.
  magic_dns: true

# Defines the base domain to create the hostnames for MagicDNS.
  # This domain _must_ be different from the server_url domain.
  # `base_domain` must be a FQDN, without the trailing dot.
  # The FQDN of the hosts will be
  # `hostname.base_domain` (e.g., _myhost.example.com_).
  base_domain: example.com

# List of DNS servers to expose to clients.

# DEPRECATED
  # Use the username as part of the DNS name for nodes, with this option enabled:
