test Docker on Mac OS X

download docker for mac and install

download from
https://github.com/boot2docker/osx-installer/releases
, install the package, which will install a VirtualBox VM, Docker itself, and the Boot2Docker management tool.

start boot2docker

To connect the Docker client to the Docker daemon, please set: export DOCKER_HOST=tcp://192.168.59.103:2375

$ export DOCKER_HOST=tcp://192.168.59.103:2375
$ boot2docker ip
The VM’s Host only interface IP address is: 192.168.59.103

run docker hello world

$ docker run —help
$ docker run hello-world
Hello from Docker.
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the “hello-world” image from the Docker Hub.
(Assuming it was not already locally available.)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
