# 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
#

#
# For production:

# to keep this endpoint private to your internal
# network

### 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
# e.g.: acme_url: https://acme-v02.api.letsencrypt.org/directory
acme_url: {{ headscale.le.acme_url }}
# Email to register with ACME provider
acme_email: "{{ headscale.le.email }}"
# Domain name to request a TLS certificate for:
# tls_letsencrypt_hostname: "{{ headscale.dns.base_domain }}"
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
tls_letsencrypt_challenge_type: TLS-ALPN-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: "{{ headscale.le.crtpath }}"
tls_key_path: "{{ headscale.le.keypath }}"

# Output formatting for logs: text or json
