Getting the Apache Kafka® patch version

If you do not have the Yandex Cloud CLI installed yet, install and initialize it.

By default, the CLI uses the folder specified when creating the profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also set a different folder for any specific command using the --folder-name or --folder-id parameter.

To get Apache Kafka® cluster details, run the following command:

yc managed-kafka cluster get <cluster_name_or_ID>

Result:

id: c9q8d856r3nt********
folder_id: b1gurba83v2i********
created_at: "2025-06-16T10:57:42.582559Z"
name: kafka947
environment: PRODUCTION
...
config:
  version: "3.6"
  kafka:
    resources:
      resource_preset_id: s3-c2-m8
      disk_size: "34359738368"
      disk_type_id: network-ssd
...
  rest_api_config:
    enabled: true
  kafka_ui_config:
    enabled: true
  patch_version: 3.6.1
...

Where patch_version is the Apache Kafka® patch version.

You can get the cluster ID and name with the list of clusters in the folder.

1. Get an IAM token for API authentication and place it in an environment variable:

   export IAM_TOKEN="<IAM_token>"
   

2. Call the Cluster.get method, e.g., via the following cURL request:

   curl \
       --request GET \
       --header "Authorization: Bearer $IAM_TOKEN" \
       --url 'https://mdb.api.cloud.yandex.net/managed-kafka/v1/clusters/<cluster_ID>'
   

   You can get the cluster ID with the list of clusters in the folder.

3. Check the server response to make sure your request was successful.

4. Find the patchVersion field the server response.

1. Get an IAM token for API authentication and place it in an environment variable:

   export IAM_TOKEN="<IAM_token>"
   

2. Clone the cloudapi repository:

   cd ~/ && git clone --depth=1 https://github.com/yandex-cloud/cloudapi
   

   Below, we assume that the repository contents reside in the ~/cloudapi/ directory.

3. Call the ClusterService/Get method, e.g., via the following gRPCurl request:

   grpcurl \
       -format json \
       -import-path ~/cloudapi/ \
       -import-path ~/cloudapi/third_party/googleapis/ \
       -proto ~/cloudapi/yandex/cloud/mdb/kafka/v1/cluster_service.proto \
       -rpc-header "Authorization: Bearer $IAM_TOKEN" \
       -d '{
               "cluster_id": "<cluster_ID>"
           }' \
       mdb.api.cloud.yandex.net:443 \
       yandex.cloud.mdb.kafka.v1.ClusterService.Get
   

   You can get the cluster ID with the list of clusters in the folder.

4. Check the server response to make sure your request was successful.
