gophercloud 是一個基於golang 包裝的openstack api，功能比較強大，使用上也很不錯，同時 也提供了比較完備的參考資料

一個參考使用demo

package main

​

import (

  "log"

​

  "github.com/gophercloud/gophercloud"

  "github.com/gophercloud/gophercloud/openstack"

  "github.com/gophercloud/gophercloud/openstack/compute/v2/servers"

  "github.com/gophercloud/gophercloud/pagination"
 

)

​

func main() {

​

  // 1. ops

  authOpts := gophercloud.AuthOptions{

    IdentityEndpoint: "https://openstack.example.com:5000/v2.0",

    Username:     "{username}",

    Password:     "{password}",

   }

  // 2. provider

  provider, err := openstack.AuthenticatedClient(authOpts)

  if err != nil {
 

    log.Fatal("some wrong", err.Error())

   }

  // 3. different ops (compute,block-storage,identity,networking,object-storage。。。。)

  client, err := openstack.NewComputeV2(provider, gophercloud.EndpointOpts{

    Region: "RegionOne",

   })

​

  // 4. servers ops

  opts := servers.ListOpts{Name: "server_1"}
 

  // Retrieve a pager (i.e. a paginated collection)

  pager := servers.List(client, opts)

​

  // page for fetch serverList

  err = pager.EachPage(func(page pagination.Page) (bool, error) {

    serverList, err := servers.ExtractServers(page)

    if err != nil {

      log.Println("some wrong:", err.Error())

      return false, err

     }

    for _, s := range serverList {

      log.Println(s)

     }

    return true, nil

   })

​

}

文件dockerfile

為了方便學習以及使用，使用wget 映象了gophercloud 的文件，同時製作了一個dockerfile
映象網站命令

wget -mkEpnp http://gophercloud.io/

dockerimage dalongrong/gophercloud-docs

說明

因為以前是rackspace 已經遷移到了gophercloud，所以目前文件可能不是很全，最好參考godoc 學習使用
