Yandex Managed Service for Apache Airflow™ 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.

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

   yc managed-airflow cluster update --help
   

2. Run this command:

   yc managed-airflow 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.

   To learn how to create this file, see Creating a cluster.

2. To set up a maintenance window, add the maintenance_window section to the cluster description:

   resource "yandex_airflow_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. Make sure the settings are correct.

   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.

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

   export IAM_TOKEN="<IAM_token>"
   

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

   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://airflow.api.cloud.yandex.net/managed-airflow/v1/clusters/<cluster_ID>' \
     --data '{
               "updateMask": "maintenanceWindow",
               "maintenanceWindow": {
                 "weeklyMaintenanceWindow": {
                   "day": "<day_of_week>",
                   "hour": "<hour>"
                 }
               }
             }'
   

   Where:

   • updateMask: Comma-separated string of settings you want to update.

     Here, we provide only one setting.

   • maintenanceWindow: Maintenance window settings (including for disabled clusters). In maintenanceWindow, provide one of the two parameters:

     • anytime: Maintenance can take place at any time.

     • weeklyMaintenanceWindow: Maintenance takes place once a week at the specified 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 with the list of clusters in the folder.

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

1. Get an IAM token for API authentication and put 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.Update method, e.g., via the following gRPCurl request:

   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 update_mask parameter as an array of paths[] strings.

   Format for listing settings

   "update_mask": {
       "paths": [
           "<setting_1>",
           "<setting_2>",
           ...
           "<setting_N>"
       ]
   }
   

   grpcurl \
     -format json \
     -import-path ~/cloudapi/ \
     -import-path ~/cloudapi/third_party/googleapis/ \
     -proto ~/cloudapi/yandex/cloud/airflow/v1/cluster_service.proto \
     -rpc-header "Authorization: Bearer $IAM_TOKEN" \
     -d '{
           "cluster_id": "<cluster_ID>",
           "update_mask": {
             "paths": ["maintenance_window"]
           },
           "maintenance_window": {
             "weekly_maintenance_window": {
               "day": "<day_of_week>",
               "hour": "<hour>"
             }
           }
         }' \
     airflow.api.cloud.yandex.net:443 \
     yandex.cloud.airflow.v1.ClusterService.Update
   

   Where:

   • update_mask: List of parameters to update as an array of strings (paths[]).

     Here, we provide only one setting.

   • maintenance_window: Maintenance window settings (including for disabled clusters). In maintenance_window, provide one of the two parameters:

     • anytime: Maintenance can take place at any time.

     • weekly_maintenance_window: Maintenance takes place once a week at the specified 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 with the list of clusters in the folder.

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