### 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: ''

# Client (Tailscale/Browser) authentication mode (mTLS)
# Acceptable values:
# - disabled: client authentication disabled
# - relaxed: client certificate is required but not verified
# - enforced: client certificate is required and verified
tls_client_auth_mode: relaxed

# Path to store certificates and metadata needed by
# letsencrypt
tls_letsencrypt_cache_dir: /var/lib/headscale/cache

## 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:
  # List of DNS servers to expose to clients.
  nameservers:
    - 1.1.1.1

  # Split DNS (see https://tailscale.com/kb/1054/dns/),
  # list of search domains and the DNS to query for each one.
  #
  # restricted_nameservers:
  #   foo.bar.com:
  #     - 1.1.1.1
  #   darp.headscale.net:
  #     - 1.1.1.1
  #     - 8.8.8.8

  # Search domains to inject.
  domains: []

  # 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.
  # `base_domain` must be a FQDNs, without the trailing dot.
  # The FQDN of the hosts will be
  # `hostname.namespace.base_domain` (e.g., _myhost.mynamespace.example.com_).
  base_domain: example.com

# Unix socket used for the CLI to connect without authentication
# Note: for local development, you probably want to change this to:
# unix_socket: ./headscale.sock
unix_socket: /var/run/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:
#   issuer: "https://your-oidc.issuer.com/path"
#   client_id: "your-oidc-client-id"
#   client_secret: "your-oidc-client-secret"
#
#   If `strip_email_domain` is set to `true`, the domain part of the username email address will be removed.
#   This will transform `[email protected]` to the namespace `first-name.last-name`
#   If `strip_email_domain` is set to `false` the domain part will NOT be removed resulting to the following
#   namespace: `first-name.last-name.example.com`
#
#   strip_email_domain: true
