与Docker的连接问题 [英] Connection issue with Docker

问题描述

我更新了我们的一个服务器，并且我在服务器上安装了Docker。一切都成功了，在一定程度上。我正在通过创建Docker映像的一个示例来处理我的错误，我收到以下错误：

sudo docker运行hello-world
无法在本地找到图像'hello-world：latest'
拉取存储库hello-world
FATA获取https://index.docker.io/v1/repositories/library/hello-world/images ：拨打tcp 162.242.195.84:443：连接超时

我正在使用我们的网络管理员进行检查，因为我可以通过浏览器浏览有关的URL，并获得以下内容JSON：

搜索网页显示一些其他人有这些错误，但决议在这里没有工作。这可能是代理还是端口问题？

我正在使用最新版本的Docker

解决方案

从您的curl命令可以看出，您正在使用代理。所以，您需要执行以下操作（在Ubuntu中）使其正常工作：_
1.编辑您的 / etc / default / docker 文件根据您的 /etc/apt/apt.conf ，取消注释和编辑行说 export http_proxy =...文件。

2. sudo service docker restart

3.最后测试 sudo docker login

I updated one of our servers and I have installed Docker on the server. Everything has been successful, to a degree. I was working my way through one of the examples of creating a Docker image and I got the following error:

sudo docker run hello-world Unable to find image 'hello-world:latest' locally Pulling repository hello-world FATA[0162] Get https://index.docker.io/v1/repositories/library/hello-world/images: dial tcp 162.242.195.84:443: connection timed out

I am checking into this with our network admins as I am able to surf, via browser, to the URL in question and get the following JSON:

Searching the web showed some others with these errors, but the resolutions did not work here. Could this be a proxy or port issue?

I am using the latest version of Docker

docker version

When I run sudo docker pull hello-world I get a timeout message even though I can curl the URL successfully -

解决方案

From your curl command, it is clear that you are using proxy. So, you need to do the following (in Ubuntu) to make it work:
1. Edit your /etc/default/docker file (Uncomment and edit line saying export http_proxy="..." based on your /etc/apt/apt.conf file.
2. sudo service docker restart
3. Finally test sudo docker login
