Docker Remote API v1.20 1. Brief introduction The Remote API has replaced rcli. The daemon listens on unix:///var/run/docker.sock but you can Bind Docker to another host/port or a Unix socket. The API tends to be REST. However, for some complex commands, like attach or pull, the HTTP connection is hijacked to transport stdout, stdin and stderr. When the client API version is newer than the daemon’s, these calls return an HTTP 400 Bad Request error message. 2. Endpoints 2.1 Containers List con

Docker and AUFS in practice AUFS was the first storage driver in use with Docker. As a result, it has a long and close history with Docker, is very stable, has a lot of real-world deployments, and has strong community support. AUFS has several features that make it a good choice for Docker. These features enable: Fast container startup times. Efficient use of storage. Efficient use of memory. Despite its capabilities and long history with Docker, some Linux distributions do not support AUFS.

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

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

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

Understand the architecture Docker is an open platform for developing, shipping, and running applications. Docker is designed to deliver your applications faster. With Docker you can separate your applications from your infrastructure and treat your infrastructure like a managed application. Docker helps you ship code faster, test faster, deploy faster, and shorten the cycle between writing code and running code. Docker does this by combining kernel containerization features with workflows and

Quickstart: Docker Compose and WordPress You can use Docker Compose to easily run WordPress in an isolated environment built with Docker containers. This quick-start guide demonstrates how to use Compose to set up and run WordPress. Before starting, you’ll need to have Compose installed. Define the project Create an empty project directory. You can name the directory something easy for you to remember. This directory is the context for your application image. The directory should only contain

Network containers If you are working your way through the user guide, you just built and ran a simple application. You’ve also built in your own images. This section teaches you how to network your containers. Name a container You’ve already seen that each container you create has an automatically created name; indeed you’ve become familiar with our old friend nostalgic_morse during this guide. You can also name containers yourself. This naming provides two useful functions: You can name conta
