Docker远程API-拉/创建映像不工作

好的，我已经启用了通过HTTP管理docker守护程序，方法是启动守护程序，如下所示：

/usr/bin/docker -d -H fd:// -H=0.0.0.0:2376

curl -v -X POST http://localhost:2376/images/create?from=ubuntu
* Hostname was NOT found in DNS cache
*   Trying 127.0.0.1...
* Connected to localhost (127.0.0.1) port 2376 (#0)
> POST /images/create?from=ubuntu HTTP/1.1
> User-Agent: curl/7.38.0
> Host: localhost:2376
> Accept: */*
> 
< HTTP/1.1 200 OK
< Content-Type: application/json
< Date: Thu, 01 Oct 2015 09:01:02 GMT
< Transfer-Encoding: chunked
< 
{"status":"Downloading from http://"}
{"errorDetail":{"message":"Get http://: http: no Host in request URL"},"error":"Get http://: http: no Host in request URL"}
* Connection #0 to host localhost left intact

我可以通过远程API创建容器并删除它们（即其他调用工作正常），但如果我尝试拉取图像，则会出现如下错误：

/usr/bin/docker -d -H fd:// -H=0.0.0.0:2376

curl -v -X POST http://localhost:2376/images/create?from=ubuntu
* Hostname was NOT found in DNS cache
*   Trying 127.0.0.1...
* Connected to localhost (127.0.0.1) port 2376 (#0)
> POST /images/create?from=ubuntu HTTP/1.1
> User-Agent: curl/7.38.0

{"errorDetail":{"message":"Get http://: http: no Host in request URL"},"error":"Get http://: http: no Host in request URL"}
* Connection #0 to host localhost left intact

curl-v-X柱http://localhost:2376/images/create?from=ubuntu
*在DNS缓存中找不到主机名
*正在尝试127.0.0.1。。。
*已连接到本地主机（127.0.0.1）端口2376（#0）

有人知道答案是什么吗？

啊，看起来是参数名中的一个输入错误

"from" -> "fromImage"

如果缺少查询参数，基本上会出现此错误

还要确保设置tag=latest，否则它会下载所有ubuntu图片
