Creating an API gateway

If you do not have the Yandex Cloud command line interface yet, install and initialize it.

The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

To create an API gateway:

1. View a description of the CLI command for creating an API gateway:

   yc serverless api-gateway create --help
   

2. Specify gateway parameters in the create command (not all the supported parameters are listed):

   yc serverless api-gateway create \
     --name <gateway_name> \
     --spec=<specification_file_path>
   

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 don't have Terraform, install it and configure the Yandex Cloud provider.

To create an API gateway:

1. Describe the parameters of the yandex_api_gateway resource in the configuration file:

   • name: API gateway name. The name format is as follows:

     • The name must be from 3 to 63 characters long.
     • It may contain lowercase Latin letters, numbers, and hyphens.
     • The first character must be a letter and the last character cannot be a hyphen.

   • description: API gateway description.

   • labels: Labels for the API gateway. Specify a key-value pair.

   • spec: API gateway specification.

   Here is an example of the configuration file structure:

   resource "yandex_api_gateway" "test-api-gateway" {
     name        = "<API_gateway_name>"
     description = "<API_gateway_description>"
     labels      = {
       label       = "label"
       empty-label = ""
     }
     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, {user}!\n"
     EOT
   }
   

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

2. Make sure the configuration files are correct.

   1. In the command line, go to the directory where you created the configuration file.

   2. Run a check using this command:

      terraform plan
      

   If the configuration is described correctly, the terminal will display a list of created resources and their parameters. If the configuration contains any errors, Terraform will point them out.

3. Deploy cloud resources.

   1. If the configuration does not contain any errors, run this command:

      terraform apply
      

   2. Confirm creating the resources: type yes in the terminal and press Enter.

      All the resources you need will then be created in the specified folder. You can check the new resources and their configuration using the management console or these CLI commands:

      yc serverless api-gateway get <API_gateway_name>
      

To create an API gateway, use the create REST API method for the ApiGateway resource or the ApiGatewayService/Create gRPC API call.

You can create an API gateway using the Yandex Cloud Toolkit plugin for the IDE family on the JetBrains IntelliJ platform.
