When I execute the command I get:
$ docker ps
Invalid bind address format: "tcp://192.168.99.100:2376"
$docker-machine rm -f default
$ docker-machine create -d virtualbox default
$ (docker-machine env default)
And now I can't list my docker images and containers. What I can do to fix it?

DOCKER_HOST. Sets the URL of the Docker daemon. Defaults to: unix:///var/run/docker.sock (same as with the Docker client).
Exposed ports are visible when you list your containers with docker ps . They'll show up in the PORTS column, even though they won't actually be accessible outside the container. This gives you a simple way of checking which ports the software inside a container is listening on.
In the latest versions of Docker, something like this is possible: docker exec <container> bash . So, you just open a shell inside the container. Similarly, you can do: docker exec <container> ls <dir path> and docker exec <container> cat <file path> . For bash however, add the -it options.
A Docker container image is a lightweight, standalone, executable package of software that includes everything needed to run an application: code, runtime, system tools, system libraries and settings.
Are the quotes part of your $DOCKER_HOST value ? If yes, that may be a problem and you could try to export DOCKER_HOST without quotes and check if it works. Posted by – Christian W Oct 2 '17 at 14:56
This was the problem in my case:
export DOCKER_HOST="tcp://192.xx.xx.xx:2376"
Supposed to be:
export DOCKER_HOST=tcp://192.xx.xx.xx:2376
