Apache Kafka® cluster maintenance

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 reschedule maintenance for a new date and time:

1. See the description of the CLI command for rescheduling maintenance :

   yc managed-kafka cluster reschedule-maintenance --help
   

2. Run this command:

   yc managed-kafka cluster reschedule-maintenance <cluster_name_or_ID> \
     --reschedule-type <reschedule_type> \
     --delayed-until <timestamp>
   

   Where:

   • reschedule-type: Reschedule type:

     • next-available-window: Next available window.
     • specific-time: Specific date and time.

   • delayed-until: Timestamp (do not use with the next-available-window reschedule type).

     The timestamp must be in one of the following formats:

     • RFC-3339.
     • HH:MM:SS.
     • Relative time to postpone maintenance for.

     Here are some examples: 2006-01-02T15:04:05Z, 15:04:05, 2h, or 3h30m ago.

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

To reschedule maintenance for a new date and time:

1. Get an IAM token for authentication in the API.

2. Save the token to an environment variable:

   export IAM_TOKEN="<IAM_token>"
   

3. Use the Cluster.rescheduleMaintenance method and send the following request, e.g., via cURL:

   curl \
     --request POST \
     --header "Authorization: Bearer $IAM_TOKEN" \
     --header "Content-Type: application/json" \
     --url 'https://mdb.api.cloud.yandex.net/managed-kafka/v1/clusters/<cluster_ID>:rescheduleMaintenance' \
     --data '{
       "rescheduleType": <reschedule_type>,
       "delayedUntil": <timestamp>
     }'
   

   Where:

   • rescheduleType: Reschedule type:

     • NEXT_AVAILABLE_WINDOW: Next available window.
     • SPECIFIC_TIME: Specific date and time.

   • delayedUntil: Timestamp in RFC-3339 format, e.g., 2006-01-02T15:04:05Z.

     Do not use this option with the NEXT_AVAILABLE_WINDOW reschedule type.

   You can get the cluster ID from the folder’s cluster list.

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

To reschedule a maintenance job to a new date and time:

1. Get an IAM token for authentication in the API.

2. Save the token to an environment variable:

   export IAM_TOKEN="<IAM_token>"
   

3. Clone the cloudapi repository:

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

   Below, we assume the repository contents are stored in the ~/cloudapi/ directory.

4. Use the ClusterService.RescheduleMaintenance call and send the following request, e.g., via gRPCurl:

   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>",
       "reschedule_type": <reschedule_type>,
       "delayed_until": <timestamp>
     }' \
     mdb.api.cloud.yandex.net:443 \
     yandex.cloud.mdb.kafka.v1.ClusterService.RescheduleMaintenance
   

   Where:

   • reschedule_type: Reschedule type:

     • NEXT_AVAILABLE_WINDOW: Next available window.
     • SPECIFIC_TIME: Specific date and time.

   • delayedUntil: Timestamp in RFC-3339 format, e.g., 2006-01-02T15:04:05Z.

     Do not use this option with the NEXT_AVAILABLE_WINDOW reschedule type.

   You can get the cluster ID from the folder’s cluster list.

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

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 start a scheduled maintenance job immediately, do the following:

1. See the description of the CLI command for rescheduling maintenance :

   yc managed-kafka cluster reschedule-maintenance --help
   

2. Run this command using the immediate reschedule type:

   yc managed-kafka cluster reschedule-maintenance <cluster_name_or_ID> \
     --reschedule-type immediate
   

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

To start a scheduled maintenance job immediately, do the following:

1. Get an IAM token for authentication in the API.

2. Save the token to an environment variable:

   export IAM_TOKEN="<IAM_token>"

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.

1. See the description of the CLI command for updating the maintenance window:

   yc managed-kafka cluster update --help
   

2. Run this command:

   yc managed-kafka cluster update <cluster_name_or_ID> \
     --maintenance-window type=<maintenance_type>,`
                         `day=<day_of_week>,`
                         `hour=<hour>
   

   Where type is the maintenance type:

   • anytime: At any time (default).
   • weekly: On a schedule. For this value, also specify the following:
     • day: Day of week, i.e., MON, TUE, WED, THU, FRI, SAT, or SUN.
     • hour: Hour of day (UTC), from 1 to 24.

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

1. Open the current Terraform configuration file describing your infrastructure.

   For more information about creating this file, see this guide.

   For a complete list of editable Managed Service for Apache Kafka® cluster configuration fields, refer to the Terraform provider guides.

2. To set up the maintenance window (for disabled clusters as well), add the maintenance_window section to the cluster description:

   resource "yandex_mdb_kafka_cluster" "<cluster_name>" {
     ...
     maintenance_window {
       type = <maintenance_type>
       day  = <day_of_week>
       hour = <hour>
     }
     ...
   }
   

   Where:

   • type: Maintenance type. The possible values include:
     • ANYTIME: Anytime
     • WEEKLY: On a schedule
   • day: Day of week for the WEEKLY type, i.e., MON, TUE, WED, THU, FRI, SAT, or SUN.
   • hour: UTC hour for the WEEKLY type, from 1 to 24.

3. Validate your configuration.

   1. In the command line, navigate to the directory that contains the current Terraform configuration files defining the infrastructure.

   2. Run this command:

      terraform validate
      

      Terraform will show any errors found in your configuration files.

4. Confirm updating the resources.

   1. Run this command to view the planned changes:

      terraform plan
      

      If you described the configuration correctly, the terminal will display a list of the resources to update and their parameters. This is a verification step that does not apply changes to your resources.

   2. If everything looks correct, apply the changes:

      1. Run this command:

         terraform apply
         

      2. Confirm updating the resources.

      3. Wait for the operation to complete.

   Time limits

   The Terraform provider limits the amount of time for all Managed Service for Apache Kafka® cluster operations to complete to 60 minutes.

   Operations exceeding the set timeout are interrupted.

   How do I change these limits?

   Add the timeouts block to the cluster description, for example:

   resource "yandex_mdb_kafka_cluster" "<cluster_name>" {
     ...
     timeouts {
       create = "1h30m" # 1 hour 30 minutes
       update = "2h"    # 2 hours
       delete = "30m"   # 30 minutes
     }
   }
   

1. Get an IAM token for authentication in the API.

2. Save the token to an environment variable:

   export IAM_TOKEN="<IAM_token>"
   

3. Use the Cluster.Update method and send the following request, e.g., via cURL:

   Warning

   The API method will assign default values to all the parameters of the object you are modifying unless you explicitly provide them in your request. To avoid this, list the settings you want to change in the updateMask parameter as a single comma-separated string.

   curl \
     --request PATCH \
     --header "Authorization: Bearer $IAM_TOKEN" \
     --header "Content-Type: application/json" \
     --url 'https://mdb.api.cloud.yandex.net/managed-kafka/v1/clusters/<cluster_ID>' \
     --data '{
       "updateMask": "maintenanceWindow",
       "maintenanceWindow": {
         "weeklyMaintenanceWindow": {
           "day": "<day_of_week>",
           "hour": "<hour>"
         }
       }
     }'
   

   Where:

   • updateMask: Comma-separated list of settings to update.

     Here, we provide only one setting.

   • maintenanceWindow: Maintenance window settings, including for disabled clusters. Possible values:

     • anytime: Maintenance can take place at any time.

     • weeklyMaintenanceWindow: Maintenance takes place once a week on the specified day and time:

       • day: Day of week in DDD format: MON, TUE, WED, THU, FRI, SAT, or SUN.
       • hour: Time of day (UTC) in HH format, from 1 to 24.

   You can get the cluster ID from the folder’s cluster list.

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

1. Get an IAM token for authentication in the API.

2. Save the token to an environment variable:

   export IAM_TOKEN="<IAM_token>"
   

3. Clone the cloudapi repository:

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