## 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

#### 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";
