## Caddyfile sync
|
||||
|
||||
If you enabled it during install, \`sync-from-caddy.sh\` runs every 15
|
||||
minutes (systemd timer: \`gatus-caddy-sync\`) and keeps one endpoint per
|
||||
Caddy site block in sync automatically — added when a new site appears,
|
||||
removed when one goes away. Every auto-added endpoint is tagged
|
||||
\`group: caddy-sync\`; the sync only ever touches entries in that group,
|
||||
so anything you add or edit by hand (a different group, the default
|
||||
external checks) is left alone no matter what.
|
||||
|
||||
Run it by hand any time instead of waiting for the timer:

||||
