Cleanup

Use cleanup to delete managed DNS records and their safemode TXT records for everything listed in the configuration file.

Run cleanup

Run the binary with the --clean flag:

./dnsupdater --clean

With Docker:

docker run -v /path/to/config.yaml:/config.yaml ghcr.io/orkarstoft/dns-updater:latest --clean

Safety guard

Cleanup relies on Safe Mode TXT records.

For each configured record, dns-updater checks that the matching safemode TXT record exists and contains the expected ownership data. It only deletes the A record and its safemode TXT record when that ownership check passes.

If the TXT record is missing or its ownership data does not match, dns-updater skips that record and logs an error. This prevents cleanup from deleting records that dns-updater does not own.
