使用golang和docker守护进程交互

开发语言 golang

使用 unix domain socket 和 docker 守护进程交互，查询 镜像列表

package main

import ( "fmt" "net" "io/IoUtil" "encoding/json" )

type Image struct { Created uint64 Id string ParentId string RepoTags []string Size uint64 VirtualSize uint64 }

func main() { addr := net.UnixAddr{"/var/run/docker.sock","unix"} conn,err := net.DialUnix("unix",nil,&addr) if err != nil { panic(err) }

_,err = conn.Write([]byte("GET /images/json HTTP/1.0\r\n\r\n"))
if err != nil {
    panic(err)
}

result,err_conn := IoUtil.ReadAll(conn)
if err_conn != nil {
    panic(err_conn)
}

body := getBody(result[:])

var images []Image

err_js := json.Unmarshal(body,&images)
if err_js != nil {
    panic(err_js)
}

fmt.Println("len of images: ",len(images))
fmt.Println("image.Id: ",images[0].Id)

}

func getBody(result []byte) (body []byte) { for i := 0; i <= len(result) - 4; i++ { if result[i] == 13 && result[i+1] == 10 && result[i+2] == 13 && result[i+3] == 10 { body = result[i+4:] break } } return }
