In OS X, the Docker host address is the address of the Linux VM. The VM runs completely from RAM, is a small ~24MB download, and boots in approximately 5s. The default is a lightweight Linux VM made specifically to run the Docker daemon on Mac OS X. In an OS X installation, the docker daemon is running inside a Linux VM called default. This means you can address ports on a Docker container using standard localhost addressing such as localhost:8000 or 0.0.0.0:8376. On a typical Linux installation, the Docker client, the Docker daemon, and any containers run directly on your localhost. The Docker host is the computer on which the containers run. In networking, localhost means your computer. In a Docker installation on Linux, your physical machine is both the localhost and the Docker host.

If you read through Docker's Installation on Mac OS X you'll see that on OSX, Docker containers don't run on the host machine itself: This also happened when I tried to run docker-gunicorn-nginx - everything started, but I couldn't connect to the machine. I'm not sure why the IP was different, but I tried to connect to and this didn't work either. In another Docker Quickstart Terminal, I did a docker ps to see what the container was and to get its IP Address and I got: $ docker inspect a4755 | grep IPAddress However, I went to on my browser and it didn't connect. The Shipyard installer ended with: Shipyard available at Once deployed, the script will output the URL to connect along with credential information. I followed the steps inside of a Docker Quickstart Terminal. I'm new to Docker, and I can't seem to connect to any containers.
