=head1 NAME

dnssec-cluster-keys

=head1 SYNOPSIS

 dnssec-cluster-keys [--sync|--revoke] [--zone=] [--tag=] {--nolocal} {--rebuild-cache}

 Options:
    --sync              Action to sync keys to the cluster.
    --revoke            Action to revoke keys from the cluster.
    --zone              Required. The zone to take action on.
    --tag               Required for revoke. Optional for sync.
                        If not defined during a sync, all active keys will be used.
                        Multiple tags can be defined.
    --nolocal           Optional. Do not perform the action on the local server.
                        Useful for testing.
    --rebuild-cache     Rebuild the local cache of domains with DNSSEC enabled.

 Examples:

 Sync all currently active DNSSEC keys:
 ./dnssec-cluster-keys --sync --zone=example.zone

 Sync only specific DNSSEC keys. If any of the keys are disabled locally, they will be enabled.
 ./dnssec-cluster-keys --sync --zone=example.zone --tag=46547 --tag=31016 --tag=44233

 Revoke specific DNSSEC keys from the cluster. WARNING: This will delete the keys locally also.
 ./dnssec-cluster-keys --revoke --zone=example.zone --tag=46547 --tag=31016 --tag=44233

 Revoke a DNSSEC key from the cluster, but keep the local copy.
 ./dnssec-cluster-keys --revoke --zone=example.zone --tag=12345 --nolocal

=head1 DESCRIPTION

This script is used to manage DNSSEC keys in a cPanel cluster. You must be using PowerDNS
as a nameserver, cPanel DNS clustering must be enabled, and have root privileges. This script
provides two actions, sync and revoke.
