Updating an API gateway

If you do not have the Yandex Cloud (CLI) command line interface 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 update an API gateway:

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. In the update command, specify the API gateway ID or name and the parameters to update (not all the supported parameters are listed below):

   yc serverless api-gateway update \
     --id <API_gateway_ID> \
     --new-name <new_API_gateway_name> \
     --execution-timeout <request_execution_timeout> \
     --spec=<path_to_new_specification_file>
   

   Where:

   • --id: ID of the API gateway you need to update.

   • --name: New name for the API gateway. This is an optional parameter. The naming requirements are as follows:

     • It must be from 2 to 63 characters long.
     • It may contain lowercase Latin letters, numbers, and hyphens.
     • It must start with a letter and cannot end with a hyphen.

   • --execution-timeout: Request execution timeout. The value is specified in seconds and must not exceed the set limit. This is an optional parameter. The default value is 300 seconds.

   • --spec: Path to the file with the updated API gateway specification.

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 change the name, description, or specification of the API gateway:

1. Open the Terraform configuration file and edit the name, description, execution_timeout, or spec properties, respectively.

   Here is an example of the configuration file structure:

   ...
   resource "yandex_api_gateway" "test-api-gateway" {
     name        = "some_name"
     description = "any description"
     labels      = {
       label       = "label"
       empty-label = ""
     }
     execution_timeout = "<request_execution_timeout>"
     spec              = <<-EOT
       openapi: "3.0.0"
       info:
         version: 1.0.0
         title: Test API
       paths:
         /hello:
           get:
             summary: Say hello
             operationId: hello
             parameters:
               - name: user
                 in: query
                 description: User name to appear in greetings.
                 required: false
                 schema:
                   type: string
                   default: 'world'
             responses:
               '200':
                 description: Greeting.
                 content:
                   'text/plain':
                     schema:
                       type: "string"
             x-yc-apigateway-integration:
               type: dummy
               http_code: 200
               http_headers:
                 'Content-Type': "text/plain"
               content:
                 'text/plain': "Hello again, {user}!\n"
     EOT
   }
   ...

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 change the API gateway name, description, or specification, use the update REST API method for the ApiGateway resource or the ApiGatewayService/Update gRPC API call.

To change a name, description, or specification for an API gateway, use the Yandex Cloud Toolkit plugin for the IDE family on the JetBrains IntelliJ platform.
