Creating a bus

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. View the description of the CLI command to create a bus:

   yc serverless eventrouter bus create --help
   

2. Create a bus:

   yc serverless eventrouter bus create \
     --name <bus_name> \
     --description "<description>" \
     --labels <label_list> \
     --deletion-protection
   

   Where:

   • --name: Bus name. Follow these naming requirements:

     • The name must be from 3 to 63 characters long.
     • It may contain uppercase and lowercase Latin and Cyrillic letters, numbers, hyphens, underscores, and spaces.
     • The first character must be a letter. The last character cannot be a hyphen, underscore, or space.

   • --description: Bus description. This is an optional parameter.

   • --labels: List of labels. This is an optional parameter.

     You can specify one or more labels separated by commas in <key1>=<value1>,<key2>=<value2> format.

   • --deletion-protection: Bus deletion protection. By default, protection is disabled. You cannot delete a bus with this option enabled. To disable deletion protection, specify --no-deletion-protection. This is an optional parameter.

   Result:

   id: f66aevm4ithv********
   folder_id: b1g681qpemb4********
   cloud_id: b1gia87mbaom********
   created_at: "2025-02-13T12:36:59.497985Z"
   name: my-bus-43
   description: this is my bus
   labels:
     owner: admin
   deletion_protection: true
   status: ACTIVE
   

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 create a bus:

1. In the configuration file, define the parameters of the resources you want to create:

   resource "yandex_serverless_eventrouter_bus" "example_bus" {
     name                = "<bus_name>"
     description         = "<description>"
     deletion_protection = <true|false>
   
     labels = {
       <key_1> = "<value_1>"
       <key_2> = "<value_2>"
       ...
       <key_n> = "<value_n>"
     }
   }
   

   Where:

   • name: Bus name. Follow these naming requirements:

     • The name must be from 3 to 63 characters long.
     • It may contain uppercase and lowercase Latin and Cyrillic letters, numbers, hyphens, underscores, and spaces.
     • The first character must be a letter. The last character cannot be a hyphen, underscore, or space.

   • description: Bus description. This is an optional parameter.

   • deletion-protection: Bus deletion protection, true or false. You cannot delete a bus with this option enabled. This is an optional parameter.

   • labels: List of labels. Provide labels in <key> = "<value>" format. This is an optional parameter.

   For more information about the yandex_serverless_eventrouter_bus resource parameters, see the provider documentation.

2. Create the resources:

   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 new resources using the management console or this CLI command:

   yc serverless eventrouter bus list
   

To create a bus, use the Create REST API method for the Bus resource or the Bus/Create gRPC API call.
