- Persistent storage support using new volume management system and backed Flocker or Ceph (full details)
- Docker Swarm is 1.0.0 and ready for production, tested with 1000 nodes and 30,000 containers (complete list, Announcing Swarm 1.0)
- Docker Machine code is split into core Docker Machine client and multiple binaries, one each for the driver (complete list)
- Docker Compose now runs on Windows, environment variables are supported in
docker-compose.ymlfile (complete list)
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!
Install Docker 1.9.0 CLI Binary
Download the latest Docker CLI binary:
> curl -L https://get.docker.com/builds/Darwin/x86_64/docker-1.9.0 > /usr/local/bin/docker

Install Docker Machine 0.5.0
Docker Machine allows you to create Docker Engines on your laptop, on cloud, or inside your data center.

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.
And create a new machine as:
~ > docker-machine create -d=virtualbox lab Running pre-create checks... Creating machine... Waiting for machine to be running, this may take a few minutes... Machine is running, waiting for SSH to be available... Detecting operating system of created instance... Provisioning created instance... Copying certs to the local machine directory... Copying certs to the remote machine... Setting Docker configuration on the remote daemon... To see how to connect Docker to this machine, run: docker-machine env lab
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.
> docker-machine upgrade lab Stopping machine to do the upgrade... Upgrading machine lab... Latest release for github.com/boot2docker/boot2docker is v1.9.0 Downloading https://github.com/boot2docker/boot2docker/releases/download/v1.9.0/boot2docker.iso to /Users/arungupta/.docker/machine/cache/boot2docker.iso... Starting machine back up...
Hopefully this is just a timing issue and will not occur going forward.
Docker Compose 0.5.0
Docker Compose allows to easily run multi-container applications.
> curl -L https://github.com/docker/compose/releases/download/1.5.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

> chmod +x /usr/local/bin/docker-compose
> docker-compose -v
docker-compose version: 1.5.0
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.
