Golang AWS VPC 附加Virtual private gateway

Go以AWS提供的SDK aws-sdk-go-v2來附加Virtual private gateway至VPC。

事前要求

參考「AWS 建立IAM管理使用者及credentials」設定供應用程式存取AWS需要的credentials。

參考「Golang 建立AWS VPC」建立VPC。

參考「Golang 建立AWS VPC Virtual private gateway」建立Virtual private gateway。

附加Virtual private gateway至VPC

呼叫ec2.Client.AttachVpnGateway傳入參數ec2.AttachVpnGatewayInput來附加virtual private gateway至VPC。

ec2.AttachVpnGatewayInput.VpcId填入VPC ID。

ec2.AttachVpnGatewayInput.VpnGatewayId填入Virtual private gateway ID。

main.go

package main

import (
    "context"
    "fmt"

    "github.com/aws/aws-sdk-go-v2/config"

    "github.com/aws/aws-sdk-go-v2/service/ec2"
)

func main() {
    ctx := context.TODO()
    client := NewEC2Client(ctx)

    vpcId := "vpc-0e6e56e06a48ef314"
    vpnGatewayId := "vgw-0670c529abefaee33"
    params := &ec2.AttachVpnGatewayInput{
        VpcId:        &vpcId,
        VpnGatewayId: &vpnGatewayId,
    }
    output, err := client.AttachVpnGateway(ctx, params)
    if err != nil {
        panic(err)
    }

    fmt.Println(*output.VpcAttachment.VpcId) // vpc-0e6e56e06a48ef314
    fmt.Println(output.VpcAttachment.State)  // attaching
}

func NewEC2Client(ctx context.Context) *ec2.Client {
    cfg, err := config.LoadDefaultConfig(
        ctx,
        config.WithRegion("ap-northeast-1"),
    )
    if err != nil {
        panic(err)
    }

    return ec2.NewFromConfig(cfg) // Create an Amazon EC2 service client
}

測試

執行Go應用程式輸出以下結果。

vpc-0e6e56e06a48ef314
attaching

在AWS console檢視virtual private gateway已附加至VPC。
