Organization Policy API overview

The Organization Policy API uses Kubernetes custom resources and relies on the Kubernetes Resource Model (KRM). It is used to manage the lifecycle of organization policies such as creating, updating, deleting.

To use the Organization Policy API, we recommend that you use the Kubernetes CLI kubectl. If your application needs to use its own libraries to call this API, use the following example, the full API definition, and the dedicated policy match page to build your requests.

Service endpoint and discovery document

The API endpoint for the Organization Policy API is: https://MANAGEMENT_API_SERVER_ENDPOINT/apis/constraints.gatekeeper.sh/v1beta1 where MANAGEMENT_API_SERVER_ENDPOINT is the endpoint of the Management API server.

Using the kubectl proxy command, you can access that URL in your browser or with a tool such as curl to get the discovery document for the Organization Policy API. The kubectl proxy command opens up a proxy to the Kubernetes API server on your local machine. After that command is running, you can access the document at the following URL: http://127.0.0.1:8001/apis/constraints.gatekeeper.sh/v1beta1.

Example KRM

The following is an example of a GDCHRestrictedServices object in the Organization Policy API to restrict the use of the Database Services to projects that have the label owner: dba-team.
