check if docker running? try restarting docker daemon. should trick! alternatively try setting docker environment in every command line shell:

eval "$(docker-machine env default)" 

where default name of docker machine created. make sure replace 1 created.

next, try giving current user docker previliges:

sudo usermod -ag docker $user
