Setting up variables

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 set up your variables:

1. Edit the OpenAPI specification file or create a new one, if required.

2. View the description of the CLI command for updating an API gateway:

   yc serverless api-gateway update --help
   

3. Specify the API gateway ID or name in the command and list all the variables declared in the specification as key=value:

   yc serverless api-gateway update \
     --id <API_gateway_ID> \
     --variables <list_of_variables>
   

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 provide the values of the variables declared in the API gateway specification:

1. Open the Terraform configuration file and add the variables section to it:

   resource "yandex_api_gateway" "<API_gateway_name>" {
     ...
     variables = {
       <list_of_variables>
     }
     ...
   }
   

   List the variables in key = value format, such as:

   resource "yandex_api_gateway" "<API_gateway_name>" {
     ...
     variables = {
       environment = "testing"
     }
     ...
   }
   

2. Check the configuration 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
   

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

4. Apply the changes:

   terraform apply
   

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

   You can check the API gateway update using the management console or this CLI command:

   yc serverless api-gateway get <API_gateway_name>
   

To set up variables for an API gateway specification, use the update REST API method for the ApiGateway resource or the ApiGatewayService/Update gRPC API call.
