Error when doing a docker ps

I have Docker installed and it runs fine, but when I have created a container and run it, I want to know the ID of the container, so I do a docker ps. But then I always get this message:

Get http:///var/run/docker.sock/v1.15/containers/json: dial unix /var/run/docker.sock: no such file or directory

What could be wrong here?

Make sure you export the docker environment variables:

where it says

after you run

boot2docker start

and it says:

To connect the Docker client to the Docker daemon, please set: export DOCKER_CERT_PATH=/Users/jbielick/.boot2docker/certs/boot2docker-vm export DOCKER_TLS_VERIFY=1 export DOCKER_HOST=tcp://192.168.59.103:2376

You need to export those variables. Check that they are empty with

echo $DOCKER_HOST

and if it's blank, docker can't talk to your VM.

make sure boot2docker is running:

$boot2docker start

make sure docker host variable is exposed:

# Will print boot2docker VM IP
boot2docker ip
The VM's Host only interface IP address is: 192.168.59.103

# Set docker host variable with value from previous command
export DOCKER_HOST tcp://192.168.59.103:2375

Check if the docker daemon is running on the boot2docker host

boot2docker ssh
ps aux | grep docker
/usr/local/bin/docker -d ....

If you are running on Linux make sure you are running as root user
