Migrate to Engine 1.10 Starting from version 1.10 of Docker Engine, we completely change the way image data is addressed on disk. Previously, every image and layer used a randomly assigned UUID. In 1.10 we implemented a content addressable method using an ID, based on a secure hash of the image and layer data. The new method gives users more security, provides a built-in way to avoid ID collisions and guarantee data integrity after pull, push, load, or save. It also brings better sharing of lay

Docker Swarm overview Docker Swarm is native clustering for Docker. It turns a pool of Docker hosts into a single, virtual Docker host. Because Docker Swarm serves the standard Docker API, any tool that already communicates with a Docker daemon can use Swarm to transparently scale to multiple hosts. Supported tools include, but are not limited to, the following: Dokku Docker Compose Docker Machine Jenkins And of course, the Docker client itself is also supported. Like other Docker projects, D

Quickstart: Docker Compose and Django This quick-start guide demonstrates how to use Docker Compose to set up and run a simple Django/PostgreSQL app. Before starting, you’ll need to have Compose installed. Define the project components For this project, you need to create a Dockerfile, a Python dependencies file, and a docker-compose.yml file. Create an empty project directory. You can name the directory something easy for you to remember. This directory is the context for your application ima

Install Docker Compose You can run Compose on OS X, Windows and 64-bit Linux. To install it, you’ll need to install Docker first. To install Compose, do the following: Install Docker Engine: Mac OS X installation Windows installation Ubuntu installation other system installations The Docker Toolbox installation includes both Engine and Compose, so Mac and Windows users are done installing. Others should continue to the next step. Go to the Compose repository release page on GitHub. Follow th

Get started with Docker Machine and a local VM Let’s take a look at using docker-machine for creating, using, and managing a Docker host inside of VirtualBox. Prerequisites Make sure you have the latest VirtualBox correctly installed on your system. If you used Toolbox for Mac or Windows to install Docker Machine, VirtualBox is automatically installed. If you used the Quickstart Terminal to launch your first machine and set your terminal environment to point to it, a default machine was automat

Docker Engine Quickstart This quickstart assumes you have a working installation of Docker Engine. To verify Engine is installed and configured, use the following command: # Check that you have a working install $ docker info If you have a successful install, the system information appears. If you get docker: command not found or something like /var/lib/docker/repositories: permission denied you may have an incomplete Docker installation or insufficient privileges to access Engine on your mach

Write a volume plugin Docker Engine volume plugins enable Engine deployments to be integrated with external storage systems, such as Amazon EBS, and enable data volumes to persist beyond the lifetime of a single Engine host. See the plugin documentation for more information. Command-line changes A volume plugin makes use of the -vand --volume-driver flag on the docker run command. The -v flag accepts a volume name and the --volume-driver flag a driver type, for example: $ docker run -ti -v volu
