I started with Docker QuickStart Terminal and see following

Answer 1

On Windows 7 and if you believe you are behind proxy

1. Logon to default machine

   $ docker-machine ssh default
   

2. Update profile to update proxy settings

   docker@default:~$ sudo vi /var/lib/boot2docker/profile
   

3. Append from the below as appropriate

   # replace with your office's proxy environment
   export"HTTP_PROXY=http://PROXY:PORT"
   export"HTTPS_PROXY=http://PROXY:PORT"
   
   # you can add more no_proxy with your environment.
   export"NO_PROXY=192.168.99.*,*.local,169.254/16,*.example.com,192.168.59.*"
   

4. Exit

   docker@default:~$ exit
   

5. Restart docker machine

   docker-machine restart default
   

6. Update environment settings

   eval $(docker-machine env default)
   

Above steps are slightly tweaked but as given in troubleshooting guide: https://docs.docker.com/toolbox/faqs/troubleshoot/#/update-varlibboot2dockerprofile-on-the-docker-machine

Answer 2

On Windows 10. Just right-click on the systray docker icon-> Settings... -> Rest -> Restrart Docker

Answer 3

Another scenario: if your docker network adapter is disabled, it will fail with this error. The adapter is named "vEthernet (DockerNAT)" or similar. Apparently this adapter is involved somehow in the normal docker pull behavior. Enable it back to solve the problem.

Answer 4

Update August 2016

Using Docker for Mac (version 1.12.0), was seeing issues of the form:

➜  docker pull node
Using default tag: latest
Pulling repository docker.io/library/node
Network timed out while trying to connect to https://index.docker.io/v1/repositories/library/node/images. You may want to check your internet connection or if you are behind a proxy.`enter code here`

This was resolved by updating my MacBook Pro wireless network settings to include the following DNS entry: 8.8.8.8

For further info, please see this (dated) issue which provided the answer given here.

Answer 5

If you are behind proxy kindly use below commands

sudo mkdir /etc/systemd/system/docker.service.d

sudo cd /etc/systemd/system/docker.service.d

sudo vi http-proxy.conf

[Service]

Environment=HTTP_PROXY=http://proxy-server-ip:port" "NO_PROXY=localhost,127.0.0.1"

sudo systemctl daemon-reload 

sudo systemctl show --property=Environment docker

sudo systemctl restart docker

Try this if you can fetch latest ubuntu

sudo docker run -it ubuntu bash

Unable to find image ubuntu:latest locally

latest: Pulling from library/ubuntu b3e1c725a85f: Pull complete

4daad8bdde31: Pull complete

Status: Downloaded newer image for ubuntu:latest

It worked for me finally :)

Answer 6

Restarting Docker or recreating the image did not help. I rebooted Windows to no avail.

Astoundingly, when I ssh'ed into the running container and did curl https://index.docker.io/v1/repositories/library/hello-world/images I got a perfectly valid response.

I used the Docker Toolbox with VirtualBox on 64bit Windows 10 Pro.

The solution in my case was to uninstall the old Docker version and install the new one that uses Hyper-V instead of VirtualBox.

Now Docker works again.
