Docker not working in Windows10
You may need another couple of steps additional to what @programmerq mentioned.
- Create empty text file:
C:\Users\<user>\.docker\machine\machines\default\config.json
- Stop
VBoxHeadless.exe
service from Windows task manager
Try docker-machine rm -f default
and docker-machine create -d virtualbox --virtualbox-memory 2048 default
commands afterwards to remove/add default
It looks like something bad happened to your docker-machine default machine.
To recover, do the following:
docker-machine rm -f default
Next, open the virtualbox GUI and make sure that there isn't a VM that corresponds with that old "default" VM, just in case. If there is, manually delete it from there.
Now, open the quickstart terminal again and it should create a new "default" virtual machine for you.
Alternatively, you can create it like this:
docker-machine create -d virtualbox --virtualbox-memory 2048 default
At that point, your sequence of commands should work as expected again.
