Question

I installed Docker-Toolbox just now while following their webpage

I started with Docker QuickStart Terminal and see following

Answer 1

I ran into this problem running Docker on my MAC(host) with Docker VM in VBOX 5.10. It is a networking issue. The simple fix is to add a bridged network to the VBOX image. You can use the included NAT config present with the VM, but you need to change the ssh port from 50375 to 2375.

Answer 2

I had this same problem with boot2docker and fixed it by restarting it with:

boot2docker restart

Answer 3

The simpler solution is to add the following entry in /etc/default/docker file

export http_proxy="http://HOST:PORT/"

and restart the docker service

service docker restart

Answer 4

If you are behind proxy it is not enough to set HTTP_PROXY and HTTPS_PROXY env. You should set it while machine creation.

Paramer for this is --engine-env:

docker-machine create -d "virtualbox" --engine-env HTTP_PROXY=http://<PROXY>:<PORT> --engine-env HTTPS_PROXY=<PROXY>:<PORT> dev

Answer 5

I installed Docker without the Toolbox on Windows 10, so the version that requires Hyper-V to be enabled.

For Docker version 1.12 I had to go into the taskbar, right click the Docker Icon, select Settings -> Network and set the DNS Server to fixed, so that is uses Google's DNS server at 8.8.8.8.

Once that setting was changed, it finally worked.

Answer 6

I had the same problem this morning and the following fixed it for me:

$ docker-machine restart default      # Restart the environment
$ eval $(docker-machine env default)  # Refresh your environment settings

It appears that this is due to the Docker virtual machine getting itself into a strange state. There is an open github issue here
