Docker Websocket附加在NodejS中

我想用Websockets连接到Docker API，但是，在任何容器，它只是给了我403禁止错误。 我不知道我在做什么错，没有足够的文件，但这是我的代码：

var docker = require('docker.io')({ socketPath: false, host: "http://127.0.0.1", port: "4500" }); var WebSocket = require('ws'); var opts = { "AttachStdin": true, "AttachStdout": true, "AttachStderr": true, "Tty": true, "OpenStdin": true, "Cmd": [ "/bin/bash" ], "Image": "ubuntu" }; docker.containers.create(opts, function(err, result) { if (!err) { var containerId = result.Id; console.log("Container", containerId, "created"); docker.containers.start(containerId, function(err, result) { console.log(result); var ws = new WebSocket('ws://127.0.0.1:4500/v1.7/containers/' + containerId + '/attach/ws?logs=1&stderr=1&stdout=1'); ws.on("open", function() { console.log("ok, open"); }); ws.on("message", function(msg) { console.log("msg", msg); }); ws.on("error", function(msg) { console.log("error", msg); }); }); } else { console.log(err); } }); 

它产生的输出是：

 Container ceeef5eb34acf06dad7d6fea01dd71d9b0283c63b14bc52d49585aa379ec4922 created error [Error: unexpected server response (403)] 

但是我看到Docker守护进程输出如下：

 Local (127.0.0.1) DNS resolver found in resolv.conf and containers can't use it.

正如可以看到请求来到守护进程，但没有迹象表明为什么它给出了一个403禁止错误。

似乎我需要将127.0.0.1更改为localhost ，它神奇地工作。
