## 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
server_url = "https://headscale.kun.is";
## 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
listen_addr = "0.0.0.0:8080";
## 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
metrics_listen_addr = "0.0.0.0:9090";
## 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:
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

private_key_path = "/etc/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
prefixes = {
v6 = "fd7a:115c:a1e0::/48";
v4 = "100.64.0.0/10";

## 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),

#### 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
log = {
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 file containing ACL policies.
# # The file can be in YAML or HuJSON format.
# path: ""
policy.mode = "database";
### 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/
##
#dns_config:
# # Whether to prefer using Headscale provided DNS or use local.
# override_local_dns: true
# # List of DNS servers to expose to clients.
# nameservers:
# - 1.1.1.1
# # NextDNS (see https://tailscale.com/kb/1218/nextdns/).
# # "abc123" is example NextDNS ID, replace with yours.
# #
# # With metadata sharing:
# # nameservers:
# # - https://dns.nextdns.io/abc123
# #
# # Without metadata sharing:
# # nameservers:
# # - 2a07:a8c0::ab:c123

# # Extra DNS records
# # so far only A-records are supported (on the tailscale side)

# # # you can also put it in one line
# # - { name: "prometheus.myvpn.example.com", type: "A", value: "100.64.0.3" }
# # Whether to use [MagicDNS](https://tailscale.com/kb/1081/magicdns/).
# # Only works if there is at least a nameserver defined.
# magic_dns: true
# # DEPRECATED
# # Use the username as part of the DNS name for nodes, with this option enabled:
# # node1.username.example.com
# # while when this is disabled:
# # node1.example.com
# # This is a legacy option as Headscale has have this wrongly implemented
# # while in upstream Tailscale, the username is not included.
# use_username_in_magic_dns: false
# # 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.user.base_domain` (e.g., _myhost.myuser.example.com_).
# base_domain: example.com
## Unix socket used for the CLI to connect without authentication
## Note: for production you will want to set this to something like:
#unix_socket: /var/run/headscale/headscale.sock
#unix_socket_permission: "0770"
##
## headscale supports experimental OpenID connect support,
## it is still being tested and might have some bugs, please
## help us test it.
## OpenID Connect
## oidc:
## only_start_if_oidc_is_available: true
## issuer: "https://your-oidc.issuer.com/path"
## client_id: "your-oidc-client-id"
## client_secret: "your-oidc-client-secret"
## # Alternatively, set `client_secret_path` to read the secret from the file.
## # It resolves environment variables, making integration to systemd's
## # `LoadCredential` straightforward:
## client_secret_path: "${CREDENTIALS_DIRECTORY}/oidc_client_secret"
## # client_secret and client_secret_path are mutually exclusive.
##
## # The amount of time from a node is authenticated with OpenID until it
## # expires and needs to reauthenticate.
## # Setting the value to "0" will mean no expiry.
## expiry: 180d
##
## # Use the expiry from the token received from OpenID when the user logged
## # in, this will typically lead to frequent need to reauthenticate and should
## # only been enabled if you know what you are doing.
## # Note: enabling this will cause `oidc.expiry` to be ignored.
## use_expiry_from_token: false
##
## # Customize the scopes used in the OIDC flow, defaults to "openid", "profile" and "email" and add custom query
## # parameters to the Authorize Endpoint request. Scopes default to "openid", "profile" and "email".
##
## scope: ["openid", "profile", "email", "custom"]
## extra_params:
## domain_hint: example.com
##
## # List allowed principal domains and/or users. If an authenticated user's domain is not in this list, the
## # authentication request will be rejected.
##
## allowed_domains:
## - example.com
## # Note: Groups from keycloak have a leading '/'
## allowed_groups:
## - /headscale
## allowed_users:
## - alice@example.com
##
## # If `strip_email_domain` is set to `true`, the domain part of the username email address will be removed.
## # This will transform `first-name.last-name@example.com` to the user `first-name.last-name`
## # If `strip_email_domain` is set to `false` the domain part will NOT be removed resulting to the following
## user: `first-name.last-name.example.com`
##
## strip_email_domain: true
## Logtail configuration
## Logtail is Tailscales logging and auditing infrastructure, it allows the control panel
## to instruct tailscale nodes to log their activity to a remote server.
#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
## default static port 41641. This option is intended as a workaround for some buggy
## firewall devices. See https://tailscale.com/kb/1181/firewalls/ for more information.
