### 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/ref/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

## 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.

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

# - 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.

#   # Map legacy users from pre-0.24.0 versions of headscale to the new OIDC users
#   # by taking the username from the legacy user and matching it with the username

#   # to force them using the unique identifier from the OIDC and to give them a
#   # proper display name and picture if available.
#   # Note that this will only work if the username from the legacy user is the same
#   # and there is a possibility for account takeover should a username have changed
#   # with the provider.
#   # When this feature is disabled, it will cause all new logins to be created as new users.
#   # Note this option will be removed in the future and should be set to false
#   # on all new installations, or when all users have logged in with OIDC once.
