Upgrade an existing installation¶
Required update path
Its required to update from one stable version to the next (e.g. 0.26.0 → 0.27.1 → 0.28.0) without skipping minor versions in between. You should always pick the latest available patch release.
Update an existing Headscale installation to a new version:
- Read the announcement on the GitHub releases page for the new version. It lists the changes of the release along with possible breaking changes and version-specific upgrade instructions.
- Stop Headscale
- Create a backup of your installation
- Update Headscale to the new version, preferably by following the same installation method.
- Compare and update the configuration file.
- Start Headscale
Backup¶
Headscale applies database migrations during upgrades and we highly recommend to create a backup of your database before upgrading. A full backup of Headscale depends on your individual setup, but below are some typical setup scenarios.
A installation that follows our official releases setup guide uses the following paths:
- Configuration file:
/etc/headscale/config.yaml - Data directory:
/var/lib/headscale - SQLite as database:
/var/lib/headscale/db.sqlite
A installation that follows our container setup guide uses a single source volume directory that contains the configuration file, data directory and the SQLite database.
Please follow PostgreSQL's Backup and Restore documentation to create a backup of your PostgreSQL database.
