Golang 建立AWS Direct Connect Connection

Go以AWS提供的SDK aws-sdk-go-v2來建立Direct Connect Connection。

範例環境：

• Go 1.19

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 API client」建立Direct Connect API client。

建立Diret Connect Connection

呼叫directconnect.Client.CreateConnection傳入參數directconnect.CreateConnectionInput來建立Direct Connect Connection。

directconnect.CreateConnectionInput的屬性Location、Bandwidth、ProviderName等可參考在AWS Console建立Direct Connect Connection的選單值。

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)

    connectionName := "demo-connection-001"
    location := "CHT51" // Chunghwa Telecom, Taipei, TWN
    bandWidth := "1Gbps"
    providerName := "Chunghwa Telecom"
    params := &directconnect.CreateConnectionInput{
        ConnectionName: &connectionName,
        Location:       &location,
        Bandwidth:      &bandWidth,
        ProviderName:   &providerName,
    }
    output, err := client.CreateConnection(ctx, params)
    if err != nil {
        panic(err)
    }

    fmt.Println(*output.ConnectionId) // dxcon-fg5kq63s
}

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。

在AWS Console檢視剛由Go程式建立的Direct Connect Connection。

• Golang 取得AWS Direct Connect Connection
• Golang 修改AWS Direct Connect Connection
• Golang 刪除AWS Direct Connect Connection
• Golang 建立AWS Direct Connect Private Virtual Interface
