Golang AWS VPC 分離Virtual private gateway

Go以AWS提供的SDK aws-sdk-go-v2來分離Virtual private gateway與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 AWS VPC 附加Virtual private gateway」建立Virtual private gateway並附加至VPC。

分離Virtual private gateway與VPC

呼叫ec2.Client.DetachVpnGateway傳入參數ec2.DetachVpnGatewayInput來分離Virtual private gateway與VPC。

DetachVpnGatewayInput.VpnGatewayId填入要分離的Virutal private gateway的ID。

DetachVpnGatewayInput.VpcId填入要分離的VPC ID。

main.go

package main

import (
    "context"

    "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)

    vpnGatewayId := "vgw-0670c529abefaee33"
    vpnId := "vpc-0e6e56e06a48ef314"
    params := &ec2.DetachVpnGatewayInput{
        VpnGatewayId: &vpnGatewayId,
        VpcId:        &vpnId,
    }

    _, err := client.DetachVpnGateway(ctx, params)
    if err != nil {
        panic(err)
    }
}

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應用程式後在AWS console檢視Virtual private gateway已無附加的VPC。

Virtual private gateway與VPC分離後，則Direct Connect gateway與Virtual private gateway的關聯也會隨之解除。
