Golang 查詢GCP公用作業系統映像檔 Query public OS images

Go以Google API Client Libraries來查詢public OS Images。

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。

下載API modules

在專案根目錄執行以下命令下載需要的google-api-go-client modules。

• go get google.golang.org/api/compute/v1

查詢Public OS Images

呼叫compute.ImagesService.List輸入project id取得OS images；public id輸入要查詢public OS images的image project名稱，例如Debian為debian-cloud。Image project請見Operating system details。

範例使用compute.ImagesListCall.Filter來篩選查詢結果資料，(name:debian-12-*) AND (family:debian-12)代表只回傳name欄位名稱開頭為debian-12-、family欄位值為debian-12的結果。

main.go

package main

import (
    "context"
    "fmt"

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

func main() {
    ctx := context.Background()
    computeService, err := compute.NewService(ctx)
    if err != nil {
        panic(err)
    }
    projectId := "debian-cloud"

    imagesService := compute.NewImagesService(computeService)

    call := imagesService.List(projectId)
    imageList, err := call.
        Filter("(name:debian-12-*) AND (family:debian-12)").
        Do()
    if err != nil {
        panic(err)
    }

    for _, item := range imageList.Items {
        fmt.Println(item.Name)
        fmt.Println(item.SelfLink)
    }

}
