Steps to reproduce the behavior

  • run docker ps after installing Docker for Mac with existing settings in .bash_profile

Solution:

Remove the existing settings in .bash_profile

export DOCKER_CERT_PATH="xxxxx"
export DOCKER_MACHINE_NAME="default"

Restart the terminal and docker ps should work now.

I have no DOCKER_* environment variables.
env | grep -i DOCKER
is empty.


(Scott M. Likens) #4

Same here; there’s no DOCKER_ environment variables. I find the http://var/run/docker.sock to be not right? manual says it should be unix:// if it’s a unix socket.

It looks like for me Docker is not responding; opened up the Console and that’s what it says. Did you just upgrade to Beta 8? I did and it broke.

Rebooting did fix this.
