Updating a target

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 update a target in a rule, run the following command, specifying the name or the ID of the rule and a list of targets with parameters:

yc serverless eventrouter rule update <rule_name_or_ID> \
  --target_1 <parameter_1>=<value_1>,...,<parameter_N>=<value_N> \
  --target_2 <parameter_1>=<value_1>,...,<parameter_N>=<value_N> \
  ...
  --target_N <parameter_1>=<value_1>,...,<parameter_N>=<value_N>

Example of a command with three targets:

yc serverless eventrouter rule update my-rule \
  --logging-target log-group-id=e23di6hvn5fm********,service-account-id=ajelprpohp7r******** \
  --workflow-target workflow-id=dfq28ndgtojl********,service-account-id=ajelprpohp7r******** \
  --function-target function-id=d4e27bc01uu7********,function-tag=$latest,service-account-id=ajelprpohp7r********

Result:

With Terraform, you can quickly create a cloud infrastructure in Yandex Cloud and manage it using configuration files. These files store the infrastructure description written in HashiCorp Configuration Language (HCL). If you change the configuration files, Terraform automatically detects which part of your configuration is already deployed, and what should be added or removed.

Terraform is distributed under the Business Source License. The Yandex Cloud provider for Terraform is distributed under the MPL-2.0 license.

For more information about the provider resources, see the relevant documentation on the Terraform website or its mirror.

If you do not have Terraform yet, install it and configure the Yandex Cloud provider.

To update a target in a rule:

1. Open the Terraform configuration file and edit the fragments describing the targets of interest.

   Example of a rule description in the Terraform configuration file:

   resource "yandex_serverless_eventrouter_rule" "example_rule" {
     bus_id    = "<bus_ID>"
     jq_filter = "<jq_template>"
   
     ymq {
       queue_arn            = "<queue_ARN>"
       service_account_id   = "<service_account_ID>"
     }
   
     workflow {
       workflow_id        = "<workflow_ID>"
       service_account_id = "<service_account_ID>"
     }
   
     yds {
       database           = "<path_to_database>"
       stream_name        = "<data_stream_name>"
       service_account_id = "<service_account_ID>"
     }
   
     name        = "<rule_name>"
     description = "<rule_description>"
   
     labels = {
       <key_1> = "<value_1>"
       <key_2> = "<value_2>"
       ...
       <key_n> = "<value_n>"
     }
   }
   

   For more information about yandex_serverless_eventrouter_rule properties, see this Terraform article.

2. Apply the changes:

   1. In the terminal, go to the directory where you edited the configuration file.

   2. Make sure the configuration file is correct using this command:

      terraform validate
      

      If the configuration is correct, you will get this message:

      Success! The configuration is valid.
      

   3. Run this command:

      terraform plan
      

      You will see a detailed list of resources. No changes will be made at this step. If the configuration contains any errors, Terraform will show them.

   4. Apply the changes:

      terraform apply
      

   5. Type yes and press Enter to confirm the changes.

   Terraform will create all the required resources. You can check the updates in the management console or using this CLI command:

   yc serverless eventrouter rule list
   

To update a target in a rule, use the Update REST API method for the Rule resource or the Rule/Update API call.
