Puppet Server: Admin API: Environment Cache

When using directory environments, the Puppet master caches the data it loads from disk for each environment. Puppet Server adds a new endpoint to the master’s HTTP API:

DELETE /puppet-admin-api/v1/environment-cache

To trigger a complete invalidation of the data in this cache, make an HTTP request to this endpoint.

Query Parameters

(Introduced in Puppet Server 1.1/2.1)

This endpoint accepts an optional query parameter, environment, whose value may be set to the name of a specific Puppet environment. If this parameter is provided, only the specified environment will be flushed from the cache, as opposed to all environments.


A successful request to this endpoint will return an HTTP 204: No Content. The response body will be empty.


$ curl -i --cert <PATH TO CERT> --key <PATH TO KEY> --cacert <PATH TO PUPPET CA CERT> -X DELETE https://localhost:8140/puppet-admin-api/v1/environment-cache
HTTP/1.1 204 No Content

$ curl -i --cert <PATH TO CERT> --key <PATH TO KEY> --cacert <PATH TO PUPPET CA CERT> -X DELETE https://localhost:8140/puppet-admin-api/v1/environment-cache?environment=production
HTTP/1.1 204 No Content

Relevant Configuration

Access to this endpoint is controlled by the puppet-admin section of puppetserver.conf. See the configuration page for more information.

In the example above, the curl command is using a certificate and private key. You must make sure this certificate’s name is included in the puppet-admin -> client-whitelist setting before you can use it.
