Golang 取得GCP Interconnect Cloud Router

Go以Google API Client Libraries來取得GCP Interconnect Cloud Router。

事前要求

參考「GCP 設定本機應用程式存取憑證 Application Default Credentials」設定credential。

參考「Golang 建立GCP Interconnect Cloud Router」建立Cloud Router。

取得Cloud Router

呼叫compute.RouterService.Get輸入project id、region、cloud router名稱來取得Cloud Router。

main.go

package main

import (
    "context"
    "fmt"

    compute "google.golang.org/api/compute/v1"
)

func main() {
    ctx := context.Background()
    service, err := compute.NewService(ctx)
    if err != nil {
        panic(err)
    }
    routersService := compute.NewRoutersService(service)

    projectId := "project-id-1"
    region := "asia-east1"
    routerName := "demo-cloudrouter-002"
    call := routersService.Get(projectId, region, routerName)
    router, err := call.Do()
    if err != nil {
        panic(err)
    }

    fmt.Println(router.Name)              // demo-cloudrouter-002
    fmt.Println(router.Kind)              // compute#router
    fmt.Println(router.Bgp.Asn)           // 16550
    fmt.Println(router.Bgp.AdvertiseMode) // DEFAULT
    fmt.Println(router.Network)           // https://www.googleapis.com/compute/v1/projects/project-id-1/global/networks/demo-vpc-001
    fmt.Println(router.SelfLink)          // https://www.googleapis.com/compute/v1/projects/project-id-1/regions/asia-east1/routers/demo-cloudrouter-002
}

測試

執行Go應用程式印出以下。

demo-cloudrouter-002
compute#router
16550
DEFAULT
https://www.googleapis.com/compute/v1/projects/project-id-1/global/networks/demo-vpc-001
https://www.googleapis.com/compute/v1/projects/project-id-1/regions/asia-east1/routers/demo-cloudrouter-002

在GCP console查看此instance。
