The snap provides a headscale service (headscale serve) with an initial example configuration, started automatically on install.
It also provides the headscale command to interact with the service.
You will need to configure the service by editing the configuration file at /var/snap/headscale/common/config.yaml.
See https://github.com/canonical/headscale-snap/blob/main/docs/config-reference.md for more information on configuration.
Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
