I\'ve installed Docker toolbox now and I get the error for everything:
Get http://127.0.0.1:2375/v1.20/version: dial tcp 127.0.0.1:2375: ConnectExtcp: No con
This has happened a few times for me on Windows 10 with VirtualBox 5.0.14.
It seems to be related with not shutting down VirtualBox correctly (I believe) - for example, a power cut!
Shutdown the Docker VM
Close Kitematic
Start the Docker Quickstart Terminal
Type in the terminal:
docker-machine.exe -D ls
If that does not work, try 1-3 again and this time try to regenerate certs. Then do step 4.
One thing that is odd, is that in the terminal docker images does not list them but says it cannot connect to 127.0.0.1:2375 (but docker-machine ls shows the default machine running on 192.168.99.100:2376).
