Platform CDN: Manually purging the CDN Cache

Manually purging all caches or individual objects from Platform CDN

Important Note: These instructions clear content from Platform CDN only. In order to replace it with fresh content, ensure that the content has also been purged from Acquia Varnish first.

First step: Retrieve the service_id and token

Run the following commands to SSH into your environment and use Drush to retrieve the service_id and token:

ssh [email protected]

Your SSH URL can be found in your Acquia Environment Information Section in the Cloud UI.

Run the following command to retrieve your Platform CDN Credentials:

Drupal 7

drush8 @sitegroup.env vget acquia_service_credentials

Drupal 8/Drupal 9

drush9 @sitegroup.env ev 'print_r(\Drupal\Core\Site\Settings::get("acquia_service_credentials")["platform_cdn"]["configuration"]);'

The output will be similar to the following:

{
   {
      "service_id": "1MFG0lmpFvMCoiziPbKLBB",
      "token": "NFA6ZgZaQfC1u1117WJuu3cVbf0ChlDY"
   }
}

Second step: Purge Platform CDN 
Purge Platform CDN by running one of following curl commands with the token in the header and the service_id in the URL path as shown in the following example:

Purge whole domain

curl -X POST -H "Fastly-Key:<Platform CDN Token>" -H "Accept: application/json" https://api.fastly.com/service/<Platform CDN Service ID>/purge/[DOMAIN]

Purge by tag

curl -X POST -H "Fastly-Key:<Platform CDN Token>" -H "Accept: application/json" https://api.fastly.com/service/<Platform CDN Service ID>/purge/[TAG]

Purge everything

curl -X POST -H "Fastly-Key:<Platform CDN Token>" -H "Accept: application/json" https://api.fastly.com/service/<Platform CDN Service ID>/purge_all

For example:

curl -X POST -H "Fastly-Key:NFA6ZgZaQfC1u1117WJuu3cVbf0ChlDY" -H "Accept: application/json" https://api.fastly.com/service/1MFG0lmpFvMCoiziPbKLBB/purge_all

Before manually purging the Platform CDN cache, purge your Varnish cache to ensure cache consistency.
