Docker Compose and Kubernetes with Docker for Desktop

If you’re running an edge version of Docker on your desktop (Docker for Mac or Docker for Windows Desktop), you can now stand up a single-node Kubernetes cluster with the click of a button. While I’m not a developer, I think this is great news for the millions of developers who have already been using Docker on their Macbook or Windows laptop because they now have a fully compliant Kubernetes cluster at their fingertips without installing any other tools. Developers using Docker to build containerized applications often build Docker Compose files to deploy them. With the integration of Kubernetes into the Docker product line, some developers may want to leverage their existing Compose files but deploy these applications in Kubernetes. With Docker on the desktop (as well as Docker Enterprise Edition) you can use Docker compose to directly deploy an application onto a Kubernetes Continue reading…

Live Debugging with Docker

During the DockerCon 2016 keynote, I demonstrated a development workflow with Docker for Mac, going from a fresh laptop to a running app in no time. The especially cool part was when I live-debugged a Node.js app running inside a container from my IDE, despite having no Node.js runtime installed on my laptop. Here I’m going to show you how to do it yourself. Here’s what you’ll need: Docker: I recommend Docker for Mac or Windows, which are in public beta. An IDE which supports Node.js remote debugging: I used Visual Studio Code. A Node.js application: I’ll create a simple one as part of this tutorial.   Example Application Create a directory to work from: $ mkdir node-example $ cd node-example To get our app running, we’ll need 5 files: A JavaScript file to contain the actual app code A package.json Continue reading…

Exciting Docker Datacenter updates: Deploy Compose apps in UI, full stack HA and more

Today we are releasing exciting new capabilities to the products behind the Docker Datacenter subscription (DDC). Docker Datacenter allows organizations to deploy a Containers as a Service (CaaS) platform on-premises or in their virtual private cloud. From DevOps and CI/CD to orchestration and management of container applications, DDC provides a seamless way for devs and IT teams to work together to build, ship and run their apps anywhere. Our team has been heads down since the initial launch in late February, taking in feedback and building new features.  This release brings Universal Control Plane 1.1 (UCP), Docker Trusted Registry 2.0 (DTR), and incorporates the latest Docker Engine 1.11 into the subscription with commercial support. In this release we focused on adding features around ease of use and system hardening.

High Availability Architecture and Apps with Docker Datacenter (DDC)

High availability (HA) isn’t just about keeping the lights on all the time; it’s also about quickly turning them back on when they unexpectedly go out. With software, this means capabilities for fault tolerance as well as backup and recovery. Docker Datacenter (DDC) provides this for both the container-based applications as well as the application infrastructure components (such as cluster management, orchestration, account settings, etc.). In this post we will look at how high availability is achieved in the latest release of Docker Datacenter. As a refresher, Docker Datacenter is comprised of the following software: Universal Control Plane (UCP) with Swarm for cluster orchestration and management Docker Trusted Registry (DTR) for secure image collaboration and distribution Docker Engine with commercial support to run your containerized apps

Docker 1.11: The first runtime built on containerd and based on OCI technology

We are excited to introduce Docker Engine 1.11, our first release built on runC ™ and containerd ™. With this release, Docker is the first to ship a runtime based on OCI technology, demonstrating the progress the team has made since donating our industry-standard container format and runtime under the Linux Foundation in June of 2015. Over the last year, Docker has helped advance the work of the OCI to make it more readily available to more users. It started in December 2015, when we introduced containerd ™, a daemon to control runC. This was part of our effort to break out Docker into small reusable components. With this release, Docker Engine is now built on containerd, so everyone who is using Docker is now using OCI. We’re proud of the progress we’ve made on the OCI with the 40+ members to continue the work to standardize container Continue reading…

Docker Compose and Networking: Easy, secure apps at scale

  When we released Docker 1.10 and Docker Compose 1.6 on February 4th, we provided you with an easy way to build a fully featured and scalable app. It’s amazing what you can do with just one simple file. I am constantly impressed what a docker-compose up gets you now. Networks and Volumes are now first class citizens of Docker Compose. That gives you a lot of control, allowing you to for instance put individual services on more than one network, and easily share volumes.

Webinar Q&A: Docker Basics – Orchestration

As the need for greater agility and portability drives the growth of containerization within enterprises world-wide, container orchestration tools have become increasingly important. With multiple nodes running multiple containers, enterprises now need a way to manage and deploy containers at scale. This is where orchestration is valuable. Orchestration is the ability to manage and automatically schedule container deployments onto nodes. Tools like Docker Swarm, a scalable Docker engine clustering solution, and Docker Compose, a powerful tool for deploying multi-container applications, help make orchestration seriously easy for users. These Docker native tools are the industry’s top orchestration solutions for Dockerized environments.

Compose 1.6: New Compose file for defining networks and volumes

In the previous version of Docker Engine we added a completely new system for managing networks and volumes, and we’re pleased to announce full support for these features in Docker Compose. Compose files used to describe just one thing: the services that make up your distributed application. We’ve now added networks and volumes to the mix, allowing you to describe much more complex applications. You can set up your app on your development machine with multiple network tiers and complex storage configurations, replicating how you might set it up in production. You can then take that same configuration from development, and use it to run your app on CI, on staging, and right through into production.
