# 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
#

# network
#

# Address to listen for gRPC.
# gRPC is used for controlling a headscale server

# See [docs/tls.md](docs/tls.md) for more information

# 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

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

# Only works if there is at least a nameserver defined.
magic_dns: true
# Defines the base domain to create the hostnames for MagicDNS.
# `base_domain` must be a FQDNs, without the trailing dot.

# Note: for production you will want to set this to something like:

# headscale supports experimental OpenID connect support,
# it is still being tested and might have some bugs, please

# # 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

# 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.

# 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
