docker-machine env default | eval “$(docker-machine env default)” | unable to run command docker

Question

I've tried on Windows 10, windows 7 and Mac OSX, everything went well, but I am unable to run docker command after run docker-machine env default and eval "$(docker-machine env default)" I don't get any error messages.

$ docker-machine version
docker-machine version 0.8.2, build e18a919

env default

$ docker-machine env default
export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://192.168.78.120:2376"
export DOCKER_CERT_PATH="/Users/elo/.docker/machine/machines/default"
export DOCKER_MACHINE_NAME="default"
# Run this command to configure your shell:
# eval "$(docker-machine env default)"

connect to virtualbox machine

$ eval "$(docker-machine env default)"

then I run

$ docker

command not found: docker

I tried windows 10, windows 7 and Mac, just can't communicate with Virtualbox machine, so no docker command is found

I am able to ssh default

Is there anything I missed?

This isn't your error.

Your error is that your shell cannot find the docker executable. Docker requires two pieces, the server daemon (which is running in docker-machine's VM) and the client.

Make sure you have installed the docker client and that it is available in your $PATH.

Answer 2

I think "docker-machine ssh default" will work fine here. By writing ssh you are creating a secure shell connection to your host and then you can talk to your host.
