Example 1: Creating a VPN Gateway

Scenario

This section describes how to create a VPN gateway by calling an API.

Prerequisites

• You have created a VPC. For details, see "Creating a VPC" in the Virtual Private Cloud User Guide.
• You have determined the region where the VPN gateway is to be deployed and obtained the endpoint for calling APIs based on the region.
• You have obtained a user token if you need to use token authentication. In addition, you need to add X-Auth-Token to the request header when calling an API. For details about token authentication, see "Authentication" in the Virtual Private Cloud API Reference.

The token obtained through IAM is valid for only 24 hours. When using a token for authentication, cache it to avoid frequent calling.

Data Preparation

Procedure

1. Create a VPN gateway associated with a VPC.
   1. Send POST https://{endpoint}/v5/{project_id}/vpn-gateways.
   2. Add X-Auth-Token to the request header.
   3. Specify the following parameters in the request body:

      1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

      { "vpn_gateway": { "vpc_id": "cb4a631d-demo-a8df-va86-ca3fa348c36c", "local_subnets": [ "192.168.0.0/24", "192.168.1.0/24" ], "connect_subnet": "f5741286-demo-a8df-va86-2c82bd9ee114", "eip1": { "id": "cff40e5e-demo-a8df-va86-7366077bf097" }, "eip2": { "id": "d290f1ee-demo-a8df-va86-d701748f0851" } } }

   4. Check the response.
      • The request is successful if the following response is displayed. In the response, id indicates a VPN gateway ID.

        {
            "vpn_gateway": {
                "id": "620d99b8-demo-a8df-va86-200b868f2d7d",

            "request_id": "4a739f5c-edb7-4122-b31f-b77fb1b94857"
        }

2. Query details about the VPN gateway.
   1. Send GET https://{endpoint}/v5/{project_id}/vpn-gateways/{vgw_id}.
   2. Add X-Auth-Token to the request header.
   3. Check the response.
      • The request is successful if the following response is displayed. In the response, id indicates a VPN gateway ID.
