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
})
}
文檔dockerfile
為了方便學習以及使用，使用wget 鏡像了gophercloud 的文檔，同時制作了一個dockerfile
鏡像網站命令
wget -mkEpnp http://gophercloud.io/
dockerimage dalongrong/gophercloud-docs
說明
因為以前是rackspace 已經遷移到了gophercloud，所以目前文檔可能不是很全，最好參考godoc 學習使用
