README

A Terminus plugin for upgrading a site to GCDN with bot protection and managing the DNS migration for your existing domains.

Installation

To install this plugin using Terminus 3 or later:

terminus self:plugin:install pantheon-systems/terminus-gcdn-plugin

Usage

If you have existing custom domains on your site, follow all of the steps below to upgrade and migrate your DNS.

1. Upgrade your site to GCDN

terminus gcdn:upgrade <site>

This migrates the site from Fastly to GCDN across all environments.

2. Get your DNS records and TXT verification challenges

terminus gcdn:dns <site>.live

This will show the TXT records needed for domain ownership and certificate validation.

3. Add TXT records to your DNS provider

Add the TXT records from step 2 to your DNS provider.

4. Verify your domains

Wait a few minutes for DNS propagation, then verify each domain. Verification typically takes a few minutes to complete:

terminus gcdn:verify <site>.live example.com
terminus gcdn:verify <site>.live www.example.com

5. Update your DNS records

Once verification passes, add the CNAME or A/AAAA records shown in the gcdn:dns output to point your domains to the new GCDN edge.

Help

Run terminus help gcdn:upgrade, terminus help gcdn:dns, or terminus help gcdn:verify for details on each command.
