zone2sql - convert BIND zones to SQL

zone2sql {--named-conf=PATH,--zone-file=PATH [--zone-name=NAME]} [Options]

zone2sql parses BIND named.conf files and zonefiles and outputs SQL on standard out, which can then be fed to your database.

zone2sql understands the BIND master file extension $GENERATE and will also honour $ORIGIN and $TTL.

For backends supporting slave operation there is also an option to keep slave zones as slaves, and not convert them to native operation.

zone2sql can generate SQL for the Generic MySQL, Generic PostgreSQL, Generic SQLite3 backend.

Read PATH to get the BIND configuration
Parse only the zone file at PATH Conflicts with --named-conf parameter.
When parsing a single zone without $ORIGIN statement, set ZONE as the zone name.

Output in format suitable for the default configuration of the Generic MySQL backend.
Output in format suitable for the default configuration of the Generic PostgreSQL backend.
Output in format suitable for the default configuration of the Generic SQLite3 backend.

Parse JSON in zonefile comments to set the 'disabled' and 'comment' fields in the database. See JSON COMMENTS for more information.
If the target SQL backend supports transactions, wrap every domain into a transaction for integrity and possibly higher speed.

If there's more than one SOA record in the zone (possibly because it was AXFR'd), ignore it. If this option is not set, all SOA records in the zone are emitted.
List all options
Ignore missing zone files during parsing. Dangerous.
Maintain slave status of zones listed in named.conf as being slaves. The default behaviour is to convert all zones to native operation.
Be verbose during conversion.

The Generic SQL backends have the 'comment' and 'disabled' fields in the 'records' table. The 'comment' field contains a comment for this record (if any) and the 'disabled' field tells PowerDNS if the record can be served to clients.

When a zonefile contains a comment like ; json={"comment": "Something", "disabled": true} and --json-comments is provided, the 'comment' field will contain "Something" and the 'disabled' field will be set to the database's native true value.

WARNING: Using JSON comments to disable records means that the zone in PowerDNS is different from the one served by BIND, as BIND does not handle the disabled status in the comment.
