Adding a target

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

The folder specified when creating the CLI profile is used by default. To change the default folder, use the yc config set folder-id <folder_ID> command. You can specify a different folder using the --folder-name or --folder-id parameter.

To add a target to a rule, run the following command, specifying the rule name or ID and a list of targets with their 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:

bus_id: f66epjc9llqt********
folder_id: b1g681qpemb4********

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 documentation on the Terraform website or mirror website.

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

To add a target to a rule, follow these steps:

1. Open the Terraform configuration file and add the sections describing your targets:

   Example of a rule description in the Terraform configuration file:

   resource "yandex_serverless_eventrouter_rule" "example_rule" {
     bus_id    = "<bus_ID>"
     jq_filter = "<jq_expression>"
   
     logging {
       log_group_id       = "<log_group_ID>"
       service_account_id = "<service_account_ID>"
     }
   
     workflow {
       workflow_id        = "<workflow_ID>"
       service_account_id = "<service_account_ID>"
     }
   
     function {
       function_id        = "<function_ID>"
       function_tag       = "<function_version_tag>"
       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 the yandex_serverless_eventrouter_rule resource parameters, see this Terraform article.

2. Apply the changes:

   1. In the terminal, change to the folder where you edited the configuration file.

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

      terraform validate
      

      If the configuration is correct, the following message is returned:

      Success! The configuration is valid.
      

   3. Run the command:

      terraform plan
      

      The terminal will display a list of resources with parameters. No changes are made at this step. If the configuration contains errors, Terraform will point them out.

   4. Apply the configuration changes:

      terraform apply
      

   5. Confirm the changes: type yes in the terminal and press Enter.

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

   yc serverless eventrouter rule list
   

To add a target to a rule, use the Update REST API method for the Rule resource or the Rule/Update gRPC API call.
