The Cerbos Admin API

This documentation is for a previous version of Cerbos. Choose 0.39.0 from the version picker at the top right or navigate to https://docs.cerbos.dev for the latest version.

The Admin API is an optional component of the Cerbos PDP that must be enabled by setting the server.adminAPI.enabled to true in the configuration. (See Admin API configuration for details).

Authentication is mandatory for the Admin API. Currently only basic authentication with a single admin user is supported. If no credentials are configured using the configuration, the default username and password is cerbos and cerbosAdmin.

Always change the default credentials and enable TLS for the endpoint when enabling the Admin API. See Server configuration for more information.
The Admin API is still under development and might include breaking changes in future releases.

Audit Logs

List Audit Log Entries

GET /admin/auditlog/list/{kind}

When audit logging is enabled you can view the audit log entries using this API endpoint.

There are two kinds of audit logs:

KIND_ACCESS

Captured Cerbos API access logs. These records are only available if accessLogsEnabled is set to true in the configuration.

KIND_DECISION

Decision logs captured by the engine. These records are only available if decisionLogsEnabled is set to true in the configuration.

Supported filters are:

tail

View the last N entries

between

View entries captured between two timestamps. The time range is specified by providing two ISO-8601 timestamps using the between.start and between.end query parameters.

since

View entries captured since N hours/minutes/seconds ago

lookup

View a specific entry by call ID

Response

List Policies

GET /admin/policies

Issue a GET request to the endpoint to list the policies available in the store. If the policy store supports filtering, you can optionally pass filter parameters to reduce the result set.

Use includeDisabled=true query parameter in order to include disabled policies in the response.

Use nameRegexp, scopeRegexp and versionRegexp to filter using the policy name, scope or version with case insensitive regular expressions.

curl -k -u cerbos:cerbosAdmin \
    'https://localhost:3592/admin/policies?pretty'
curl -k -u cerbos:cerbosAdmin \
    'https://localhost:3592/admin/policies?pretty&includeDisabled=true&nameRegexp=%5Efoo&scopeRegexp=bar%24&versionRegexp=default'

Get Policies

GET /admin/policy?id=policy_id

Issue a GET request to the endpoint with the list of IDs (the id query parameter can be repeated multiple times) to retrieve. The list of IDs available in the store can be retrieved using the ListPolicies API call described above.

curl -k -u cerbos:cerbosAdmin \
    'https://localhost:3592/admin/policy?id=x.yaml&id=y.yaml'

Disable Policies

POST   /admin/policy/disable?id=policy_id
PUT    /admin/policy/disable?id=policy_id
DELETE /admin/policy?id=policy_id [DEPRECATED]
This endpoint requires a mutable storage driver such as sqlite3 to be configured.

Issue a POST request to the endpoint with the list of IDs (the id query parameter can be repeated multiple times) to disable. The ID is of the form <kind>.<name>.v<version>/<scope>. A resource policy for leave_request with version default and scope acme.hr would therefore have the ID resource.leave_request.vdefault/acme.hr.

curl -k -u cerbos:cerbosAdmin -X POST \
    'https://localhost:3592/admin/policy/disable?id=principal.donald_duck.vdefault&id=derived_roles.my_derived_roles'
Response
{
  "disabledPolicies": 2 (1)
}
1 Number of policies disabled

Enable Policies

POST /admin/policy/enable?id=policy_id
PUT  /admin/policy/enable?id=policy_id
This endpoint requires a mutable storage driver such as sqlite3 to be configured.

Issue a POST request to the endpoint with the list of IDs (the id query parameter can be repeated multiple times) to enable. The ID is of the form <kind>.<name>.v<version>/<scope>. A resource policy for leave_request with version default and scope acme.hr would therefore have the ID resource.leave_request.vdefault/acme.hr.

curl -k -u cerbos:cerbosAdmin -X POST \
    'https://localhost:3592/admin/policy/enable?id=principal.donald_duck.vdefault&id=derived_roles.my_derived_roles'
Response
