Getting Started with Docker
If you’ve never installed Docker on your machine, then Docker Toolbox 1.9.0 installs everything you need to get started with Docker on Mac OS X and Windows. It even includes Virtual Box 5.0.8.
Download Docker Toolbox 1.9.0 for Mac or Windows.
Of course, you can apt-get install docker-engine on Ubuntu or yum install docker-engineon CentOS.
If you like to update binaries independently or learn how to use them to get started, read ahead!

Docker Machine has been split into multiple binaries – one for the core Docker Machine client and a binary for each driver. So the installation is different from the previous releases.

A new machine created using this could not be queried by Docker CLI (#2147). Upgrading the machine explicitly using docker-machine upgrade lab helped resolve the issue.

Hopefully this is just a timing issue and will not occur going forward.

A simple way to verify is to run three node Couchbase Cluster.

A later blog will show how to use persistent storage volumes to store the data.
Currently, Docker Compose requires docker-compose.yml from the local filesystem. It would be useful for docker-compose to use these files from a URI (#2313).
Docker Swarm 1.0.0
Docker Swarm provides native clustering for Docker. It converts a pool of Docker Engines into a single virtual engine. The tools, such as Docker CLI, that work with a single engine continues to work Swarm. So your applications that would run on a single Docker Engine can now easily run on multiple Docker Engines.
