You can list the schema registries in your project. This document shows you how to list schema registries using the Google Cloud console, the Google Cloud CLI, or the Managed Kafka API.

Required roles and permissions

To get the permissions that you need to list schema registries, ask your administrator to grant you the Managed Kafka Schema Registry Viewer (roles/managedkafka.schemaRegistryViewer) IAM role on your project and location. For more information about granting roles, see Manage access to projects, folders, and organizations.

This predefined role contains the permissions required to list schema registries. To see the exact permissions that are required, expand the Required permissions section:

Required permissions

The following permissions are required to list schema registries:

Grant the following permission on the parent location: managedkafka.schemaRegistries.list

You might also be able to get these permissions with custom roles or other predefined roles.

Higher-level roles like Managed Kafka Schema Registry Editor (roles/managedkafka.schemaRegistryEditor) and Managed Kafka Schema Registry Admin (roles/managedkafka.schemaRegistryAdmin) also lets you list schema registries.

For more information about predefined roles, see the Managed Service for Apache Kafka predefined roles.

List your schema registries

To list all your schema registries within your project, follow these steps.

Console

In the Google Cloud console, go to the Schema registries page.
Go to schema registries

The page displays a list of schema registries in your project. The list includes columns for the following properties:
- Name: the unique identifier for the schema registry.
- Region: the Google Cloud region where the schema registry is hosted.

gcloud

After installing the Google Cloud CLI, initialize it by running the following command:
```
gcloud init
```
If you're using an external identity provider (IdP), you must first sign in to the gcloud CLI with your federated identity.
Run the gcloud beta managed-kafka schema-registries list command:

gcloud beta managed-kafka schema-registries list \
    --location=LOCATION \

Replace the following:

LOCATION (required): the Google Cloud region for which to list schema registries.

For example, to list all schema registries in the us-central1 location, run the following command:

gcloud beta managed-kafka schema-registries list --location=us-central1

Sample output:

NAME             LOCATION
sr_docs      us-central1
sr_docs23    us-central1
sr23wert     us-central1

REST

To list schema registries using the REST API, perform the following steps.

Make a GET request to the schema registries collection URI for the required project and location.

GET https://managedkafka.googleapis.com/v1main/projects/PROJECT_ID/locations/LOCATION/schemaRegistries
Authorization: Bearer $(gcloud auth application-default print-access-token)

Replace the following:

PROJECT_ID (required): your Google Cloud project ID.
LOCATION (required): the Google Cloud region where you want to list the schema registries.

If the request is successful, the API returns a 200 OK status code. The response body contains a JSON object. This object includes a list of schema registry resources found in the specified location.

The following is a sample successful response:

{
  "schemaRegistries": [
    {
      "name": "projects/schema-test-project/location/us-central1/schemaRegistries/sr_docs",
      "contexts": []
    },
    {
      "name": "projects/schema-test-project/location/us-central1/schemaRegistries/moi_sr_docs23",
      "contexts": []
    },
    {
      "name": "projects/schema-test-project/location/us-central1/schemaRegistries/sr23wert",
      "contexts": []
    }
  ]
}

The list schema registry call returns an empty context field even in cases where the schema registry contains a context. To get the list of contexts for a schema registry, you can run the get schema registry API call. For more information about the REST API calls, see the REST API documentation.
