Docker and HPE: Accelerating modern app architectures in enterprise datacenters

Docker has evolved tremendously over the last 3 years to empower developers and IT operations teams to maintain greater control over their own environments without sacrificing agility. From an ops tool used by the original dotCloud team, to Docker’s commercially supported Containers-as-a-Service (CaaS) platform, Docker Datacenter (DDC), Docker has been at the forefront of this evolution. Today we are excited to announce the next evolution in the Docker story providing enterprises with infrastructure optimized for the Docker platform with the leading provider of cloud infrastructure – Hewlett Packard Enterprise (HPE). Together, Docker and HPE will deliver integrated and fully supported Docker ready HPE x86 servers, bundled with Docker’s commercially supported Engine (CS Engine) right out of the box.

To Use Physical Or To Use Virtual: That is the container deployment question

I have had a version of the following conversation more than a few times with community members trying to sort out where to run their containerized apps in production: User: So, where should I run my containers? Bare metal or VM’s Me: It’s not a question of “either / or” – that’s the beauty of Docker. That choice is based solely on what’s right for your application and business goals – physical or virtual, cloud or on premise. Mix and match as your application and business needs dictate (and change). User: But, surely you have a recommendation. Me: I’m going to give you the two word answer that nobody likes: It depends. User: You’re right, I don’t like that answer. Me: I kind of figured you wouldn’t, but it really is the right answer. There are tough questions in the Continue reading…

Deploy and Manage Any Cluster Manager with Docker Swarm

written by Sam Alba, Sr. Director of Engineering at Docker, Inc. and Andrea Luzzardi, Software Engineer at Docker, Inc. As you have seen, last week Docker Swarm reached 1.0, and now is ready for production use. Swarm is native clustering for Docker. Swarm allows production deployment and management of multi-host, multi-container distributed applications at scale.

Docker and the Three Ways of DevOps Part 3: The Third Way – Culture of Continuous Experimentation and Learning

written by John Willis, Evangelist at Docker The Third Way of DevOps completes the full cycle. It has also been referred to as just “Continuous Learning”. In DevOps speak, we sometimes allude to the word Kaizen as a method of continuous improvement in an organization. This “Kaizen” being achieved through a culture of continuous experimentation and learning throughout all activities in an organization.

Docker and the Three Ways of DevOps Part 2: The Second Way – Amplify Feedback Loops

written by John Willis, Evangelist at Docker In the previous post in this series, we discussed patterns of applying DevOps principles in a way that yields high performance outcomes. In part two, we are going to discuss what is called “The Second Way”.  This second “way” is ultimately about amplifying and shortening feedback loops such that corrections can be made fast and continuously. This is sometimes referred to as the right to left flow. A defect is not a defect unless it hits the customer. Lean principles teach us that the earlier we can catch a potential downstream defect, the less costly it will be on the overall cost of the service delivery. Therefore the three V’s also apply in this “Second Way”. Velocity of a correction in the flow is essential. Variation also plays a role in the “Second Continue reading…

Docker and the Three Ways of DevOps Part 1: The First Way – Systems Thinking

written by John Willis, Evangelist at Docker Have you read Gene Kim’s The Phoenix Project? Some of the principles behind the Phoenix Project and an upcoming book I am co-authoring with Gene (The DevOps Cookbook) have been referred to as the “Three Ways of DevOps”. These are particular patterns of applying DevOps principles in a way that yields high performance outcomes.  

Announcing Webhook Repository Subscriptions

Back in December at DockerCon Europe, we announced chained Webhooks. This enabled you to configure your deployment processes to continue only if the previous Webhook completed successfully.  Today we are excited to announce expanded Webhook capabilities. You can now set up Webhook subscriptions to repositories that you do not own but use. For example, when your favorite Official Repository is updated with a security patch you can automate your build and deploy processes to take advance of changes immediately.
