Go以AWS提供的SDK aws-sdk-go-v2
來關聯Direct Connect gateway與Virtual private gateway。
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 Direct Connect gateway」建立Direct Connect gateway。
參考「Golang AWS VPC 附加Virtual private gateway」建立Virtual private gateway並附加於VPC。
關聯Direct Connect gateway與Virtual private gateway
呼叫directconnect.Client.CreateDirectConnectGatewayAssociation
傳入參數directconnect.CreateDirectConnectGatewayAssociationInput
來建立Direct Connect gateway與Virtual private gateway的關聯。
directconnect.CreateDirectConnectGatewayAssociationInput.DirectConnectGatewayId
填入Direct Connect gateway的ID。
directconnect.CreateDirectConnectGatewayAssociationInput.VirtualGatewayId
填入Virtual private gateway的ID。
main.go
package main
import (
"context"
"fmt"
"github.com/aws/aws-sdk-go-v2/config"
"github.com/aws/aws-sdk-go-v2/service/directconnect"
)
func main() {
ctx := context.TODO()
client := NewDirectConnectClient(ctx)
directConnectGatewayId := "e44e0dfb-82b9-4e4f-bcc1-9d196f25d0af"
virtualGatewayId := "vgw-0670c529abefaee33"
params := &directconnect.CreateDirectConnectGatewayAssociationInput{
DirectConnectGatewayId: &directConnectGatewayId,
VirtualGatewayId: &virtualGatewayId,
}
output, err := client.CreateDirectConnectGatewayAssociation(ctx, params)
if err != nil {
panic(err)
}
fmt.Println(*output.DirectConnectGatewayAssociation.AssociationId) // 047dd041-3388-4907-a1df-f61de4644c0b
fmt.Println(output.DirectConnectGatewayAssociation.AssociationState) // associating
for _, prefix := range output.DirectConnectGatewayAssociation.AllowedPrefixesToDirectConnectGateway {
fmt.Println(*prefix.Cidr)
}
}
func NewDirectConnectClient(ctx context.Context) *directconnect.Client {
cfg, err := config.LoadDefaultConfig(
ctx,
config.WithRegion("ap-northeast-1"),
)
if err != nil {
panic(err)
}
return directconnect.NewFromConfig(cfg) // Create an Amazon Direct Connect service client
}
測試
執行Go應用程式輸出以下結果。
047dd041-3388-4907-a1df-f61de4644c0b

172.32.0.0/16
172.34.0.0/16
172.31.0.0/16
172.33.0.0/16
在AWS console檢視的Direct Connect gateway已關聯Virtual private gateway。
