SYNOPSIS

    gcp_dyndns.sh [OPTION]...

DESCRIPTION

    A script that reads your current IP address as assigned by your isp to

    enable automated updates to the A record in Google Cloud DNS for usage

    similar to DYNDNS

OPTIONS

    -d [FQDN]

            The DNS name that matches the incoming queries with this zone's

            DNS name as its suffix.

            This can be found in the second column by running :

                    gcloud dns managed-zones list

    -q

            Do not output messages. Set this flag if you want to run this

            script in cron. This will not stop error messages. By default

            this is not enabled.

    -t [TTL]

            The TTL in seconds that the resolver caches this resource

            record set.

            This defaults to 300 (5 minutes).

    -r [resource type]

            The resource record type of this resource record set.

            This defaults to A.

    -z [zone name]

            The managed zone that this resource record set is affiliated with.

            For example, my-zone-name; the name of this resource record set

            must have the DNS name of the managed zone as its suffix.

            This can be found in the first column by running :

                    gcloud dns managed-zones list

Examples

     Update the A record for FQDN FOOBAR.BAZ with zone name EX-SET :

            ./gcp-dyndns.sh -d foobar.baz -z EX-SET

Requirement

     This script requires that the Google Cloud SDK tools are installed and

     configured in your path and that the command gcloud is functioning

     against your Google Cloud account with access to Google Coud DNS.
