Confluent Metadata API Reference

The Confluent Metadata API has many endpoints, conceptually grouped as follows:

Authentication

Authenticates users against LDAP and returns user bearer tokens that can be used with the other MDS endpoints and components in Confluent Platform (when configured to do so).

Authorization

Authorizes users to perform specific actions. Clients are not expected to use these endpoints, which are used by Confluent Platform components (such as Connect and ksqlDB) to authorize user actions.

Role Based Access Control

• Role binding CRUD
• Role binding summaries (used by Confluent CLI)
• High-level role binding management and rollups (used by Confluent Control Center)

Centralized ACL Control

• With Authorization using centralized ACLs Confluent Platform provides the option to store ACLs in Kafka instead of ZooKeeper
• ACL CRUD for legacy Kafka-managed and centralized MDS-based ACLs

Audit Log Configuration

Configuration governing which events get logged, and where those audit log events are sent. Works in conjunction with the Cluster Registry to push configuration changes to Kafka clusters.

Cluster Registry

Tracking and naming CP components / clusters.

• Manually populated and updated by Admins.
• Leveraged by the Audit Log configuration.
• Leveraged by RBAC APIs to allow for RoleBinding calls to use “nice names” for clusters instead of cluster IDs.

Note

In all the RBAC CRUD APIs where you used to have to specify cluster IDs, if you have registered clusters with Cluster Registry, you can use the clusterName instead. However, you must adhere to the following restrictions:

• Use clusterName or clusters, but not both.
• When you use clusters, kafka-cluster is always required, because other clusters types do not have unique IDs.

Access Restrictions

Some endpoints can be called by any authenticated user, while others can only be called by “admins”. Additionally, many of the endpoints in the API involve two users: the user who is calling the endpoint (the “calling” principal) and the user that the API call is about (the “target” principal).

Example: User “alice”, who has the UserAdmin role, and is identified by her HTTP Basic authentication credentials or a bearer token, calls the CRUD endpoint to modify role bindings about user “bob”.

To document what access restrictions each endpoint has, use the following legend, which lists access in order from least restrictive to most restrictive:

LDAP

Any authenticated LDAP user

Admins+User

Admins or users requesting information about themselves

Admins+ResourceOwners

Admins or users with ResourceOwner role

Admins+AclUsers

Admins or the user having the required ACL permissions

Admins

Admins only, which can be UserAdmin, SystemAdmin, broker super.user, or SecurityAdmin as “Read”

Overview of Responses

Valid Responses

• 200: Successful call with a return body.
• 204: Successful call with no return body.

Errors

• 400: Invalid request. JSON parsing error, or otherwise incorrect request.
• 401: Not Authenticated. You need to pass valid HTTP Basic authentication credentials or a user bearer token.
• 403: Not Authorized. Valid request, but you aren’t authorized to perform the requested action.
• 404: Invalid URL. If you get this error from the authenticate endpoint, it means bearer token authentication needs to be enabled in the configuration (confluent.metadata.server.authentication.method=BEARER)
• 405: Method Not Allowed. Using the wrong HTTP method on a valid endpoint (for example, GET instead of POST).
• 409: Conflict. Adding a new resource or updating an existing resource that would result in a conflict with existing state.
  • This error can be thrown by Audit Logs and Cluster Registry APIs.
• 415: Invalid Content Type. Usually, a consequence of “application/json” as request body header.
• 500: Server Error.

Special Resource Types

Cluster and KsqlCluster are special ResourceTypes because they grant resource-scoped roles like ResourceOwner and DeveloperManage limited access to cluster-level operations (for example, Describe Configs on Kafka clusters). These special resource types only accept LITERAL patterns with the values kafka-cluster and ksql-cluster, respectively.

Exploring the API

The Metadata Service ships with an OpenAPI spec that you can explore and interact with using an embedded Swagger UI.

To enable the embedded Swagger UI, specify the following property in the broker’s configuration when configuring the Metadata Service: confluent.metadata.server.openapi.enable=true.

This will make the Swagger UI available on the broker as http://<host>:<port>/security/openapi/swagger-ui/index.html.

Note

Specify the same port that MDS is listening on as the Swagger UI port (the default is 8090).

Warning

The Swagger UI and the Open API spec file are provided for development and test purposes only:

• Do not enable in production environments.
• The Swagger UI works only with HTTP.

Private RBAC UI Endpoints

These endpoints were developed specifically to power the Confluent Control Center UI. As such, they only focus on those use cases and have only been tested in the context of Confluent Control Center. These endpoints have not been tested, nor has their usability been evaluated with respect to manual API calls.

GET /security/1.0/audit/routes

Lists all currently defined routes that match the queried resource or its sub-resources.

Multiple routes may match a resource, but only the most specific route will be selected for events related to the resource. This endpoint returns all matching routes regardless of whether or not they would actually be selected, or ignored in favor of a more specific route.

Requires the “AuditAdmin” role on the metadata service (MDS) cluster and every Kafka cluster in the cluster registry.

Callable by Admins.

The CRN patterns in the audit log config routes can contain wildcards. So a route with a CRN pattern like crn://mds.example.com/kafka=*/topic=finance-* would match events associated with the topic at address crn://mds.example.com/kafka=abc123/topic=finance-deposits, or events associated with the topic at crn://mds.example.com/kafka=xyz789/topic=finance-chargebacks, but would not match events associated with the topic crn://mds.example.com/kafka=abc123/topic=server-deployments. So a route’s CRN pattern can match events from more than one resource, based on where the pattern’s wildcards are.

It is possible to write multiple routes with different CRN patterns that match a given resource’s CRN. For example: the resource at crn://mds.example.com/kafka=abc123/topic=finance-chargebacks is matched by any of the following route CRN patterns:

• crn://mds.example.com/kafka=*/topic=*
• crn://mds.example.com/kafka=abc123/topic=*
• crn://mds.example.com/kafka=*/topic=finance-*

When there are multiple matching routes for an event, we select the matching route with the most specific CRN pattern. The most specific CRN pattern is the one with the greatest length before its first wildcard. So in the above example, crn://mds.example.com/kafka=abc123/topic=* wins.

To break a tie, ignore the prefix that the patterns have in common. So, for example crn://mds.example.com/kafka=*/topic=finance-* is more specific than crn://mds.example.com/kafka=*/topic=*.

This endpoint lists all currently defined routes that match the queried resource or its sub-resources, regardless of whether or not they would actually be selected, or ignored in favor of a more specific route.

A query pattern like …

crn://mds1.example.com/kafka=abcde_FGHIJKL-01234567/connect=qa-test

… would match all of the following routes …

crn://mds1.example.com/kafka=abcde_FGHIJKL-01234567/connect=qa-test/connector=from-db4

crn://mds1.example.com/kafka=abcde_FGHIJKL-01234567/connect=qa-test/connector=*

crn://mds1.example.com/kafka=*/connect=qa-*

crn://mds1.example.com/kafka=*/connect=qa-*/connector=*

… but would not match any of these routes …

GET /security/1.0/audit/lookup

Returns the route describing how messages regarding this CRN would be routed.

Requires the “AuditAdmin” role on the metadata service (MDS) cluster and every Kafka cluster in the cluster registry.

The CRN patterns in the audit log config routes can contain wildcards. So a route with a CRN pattern like crn://mds.example.com/kafka=*/topic=finance-* would match events associated with the topic at address crn://mds.example.com/kafka=abc123/topic=finance-deposits, or events associated with the topic at crn://mds.example.com/kafka=xyz789/topic=finance-chargebacks, but would not match events associated with the topic crn://mds.example.com/kafka=abc123/topic=server-deployments.

To break a tie, ignore the prefix that the patterns have in common. So, for example crn://mds.example.com/kafka=*/topic=finance-* is more specific than crn://mds.example.com/kafka=*/topic=*.

This endpoint resolves the matching and precedence rules of all configured audit log routes for you, and returns the one selected (most specific) matching route describing how messages regarding the given CRN would be routed. Callable by Admins.

Query Parameters:  

• crn (string) – A Confluent resource name (CRN).

Example request:

GET /security/1.0/audit/lookup HTTP/1.1
Host: example.com

Status Codes:

• 200 OK –

  The CRN pattern of the route that will be selected and used by the system (or else the string "default"), and the route’s rules for various audit log event categories. Categories include produce, consume, interbroker, authorize, authentication, management, heartbeat`, and describe. If needed, the server fills in any missing or null values in the rules by coalescing with defaults: authentication, authorize, and management categories will default to the destination topics specified in default_topics. All other categories default to an empty string. Rules that resolve to an empty string indicate that events will be discarded.
