Plan Your DockerCon 2018 Conference Experience: Everything an Enterprise Architect Needs to Know

DockerConSan Francisco 2018 is just around the corner and we’re here to help Enterprise Architects learn what Docker can do for them. DockerCon isn’t just for developers and we want to help you find the sessions and experiences that we’ve created that are developed with this role in mind:

In 2015, I attended DockerCon for the first time. I was sitting in a chair and listening to the amazing stories and ideas presented by speakers at the conference, which set off a chain of events that led to today. I feel privileged, and am really looking forward to being on stage and sharing our transformational journey to inspire the people who would sit in that chair.

The first thing to notice is that as you build your DockerCon agenda this year, we have a “Journey” theme that will help guide you during the conference. Whether you’re just “Getting Started” in your learning about containerization or you want to hear about “Innovation” using the Docker container platform for data sciences, AI, machine learning, and IoT, we have sessions that will be just right for you.

You can will also find content we’ve Continue reading

Windows Containers in Docker Enterprise Edition 2.0 – Top 7 Questions from the Docker Virtual Event

The recent Docker Virtual Event, Unveiling Docker Enterprise Edition (EE) 2.0, gave us the opportunity to highlight some of the great reasons to adopt a containerization strategy across your entire application portfolio. In Part 1 of this blog, we covered some of the top questions we received about Swarm and Kubernetes orchestration in Docker Enterprise Edition – the world’s leading enterprise-ready container platform. Today, we will cover some of questions about running Windows containers.

If you missed the live event, don’t worry! You can still catch the recording on-demand here.

Docker Enterprise Edition: Only Fully-Supported Solution for Running Containers on Windows Server 2016

Q: I thought containers were based on Linux processes. How do Windows-based Docker containers work?

A: Docker has been partnering with Microsoft since 2014 to deliver all the same benefits of Docker containers to Windows Server so that customers can easily run .NET and IIS applications in Docker containers. We worked closely together on changes to the Windows Server kernel to support containerization primitives, added Windows Server support to the Docker Engine and CLI  and added multi-architecture support for Windows images. The result is Docker containers run natively on Windows Server 2016, leveraging the Continue reading

Freedom from Lock-in With Docker Enterprise Edition

Major business initiatives such as digitization and cloud migration have threatened to disrupt IT organizations that are already spread thin simply supporting the core business. Containerization is viewed as a way to help with these initiatives because they speed the delivery of software and typically cut operational costs by more than 50% in the first year alone. To support a containerization strategy, many enterprises are turning to container platforms to manage and secure the delivery of their mission-critical software from development through production.

Docker EEFor customers, choosing the right container platform is more than a technical decision – it is a business decision. As with any decision of this nature, it is critical that the container solution has the flexibility to evolve as business requirements change. Unfortunately, all container platforms are not the same – some lack security while others force organizations into a prescriptive operating model. And even worse, most container platforms will “lock in” an organization to a single OS, single cloud, single type of application, single development  –  leading CIOs down a single dead-end path they will have to abandon in less than two years.

So how can organization address continue to move forward with modern technologies, Continue reading

Integrating Kubernetes with Docker Enterprise Edition 2.0 – Top 10 Questions from the Docker Virtual Event

At our recent virtual event, we shared our excitement around Docker Enterprise Edition (EE) 2.0 – the most complete enterprise-ready container platform in the market. We shared how this release enables organizations like Liberty Mutual and Franklin American Mortgage Company, both presenters at DockerCon 2018, to efficiently scale their container environment across many teams while delivering choice and flexibility. We demonstrated some of the new advanced capabilities around access controls with secure application zones and building a consistent software supply chain across regions, and highlighted how easy and interchangeable it is to leverage both Swarm and Kubernetes orchestration in the same environment.

If you missed the live event, don’t worry! You can still catch the recording on-demand here.

We got great questions throughout the event and will address the most common ones in our blog over the next few days.

Choice of Orchestration – Swarm and Kubernetes

One of the highlights of this release is the integration of Kubernetes, making Docker EE the only platform that runs both Swarm and Kubernetes simultaneously on the same cluster – so developers do not need to make an orchestration choice. Operations teams have the flexibility to choose orchestrators interchangeably.

Docker EE with Kubernetes

Q: Is Continue reading

Docker Compose and Kubernetes with Docker for Desktop

With KubeCon EU happening in Copenhagen, we looked back at the most popular posts with our readers on Docker and Kubernetes. For those of you that have yet to try Docker EE 2.0, this blog highlights how in Docker for Desktops you can use Docker compose to directly deploy an application onto a Kubernetes cluster. 

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 Continue reading

What are Docker Captains looking forward to at DockerCon

With less than 6 weeks until DockerCon 2018, we can barely contain our excitement! From their favorite tips and tricks for using Docker in production or levering Docker for Machine Learning, Docker Captains come together at DockerCon to share their knowledge and collaborate with the broader community. We’ve asked Docker Captains to share what they are most looking forward to at DockerCon. Here are some of their responses.  



“I’m looking forward to meeting the many other Docker enthusiasts and champions and listening to other cool things that Docker makes possible” – Kinnary Jangla, Pinterest

“ In 2015, I attended DockerCon for the first time. I was sitting in a chair and listening to the amazing stories and ideas presented by speakers at the conference, which set off a chain of events that led to today. I feel privileged, and am really looking forward to being on stage and sharing our transformational journey to inspire the people who would sit in that chair. I am also looking forward to hearing the keynotes and the exciting new announcements that I am sure are being lined up for the big event.” – Alexandre Iankoulski, Baker Hughes

Automating Compliance for Highly Regulated Industries with Docker Enterprise Edition and OSCAL

OSCAL Docker

Source: and C2 Labs 

Highly-regulated industries like financial services, insurance and government have their own set of complex and challenging regulatory IT requirements that must be constantly maintained. For this reason, the introduction of new technology can sometimes be difficult. Docker Enterprise Edition provides these types of organization with both a secure platform on which containers are the foundation for building compliant applications and a workflow for operational governance at scale.

The problem remains that even with the technology innovation of containers, cloud and other new tools, the area of IT compliance has remained relatively unchanged with security standards that lag far behind, creating mismatches of traditional controls to modern systems. Organizations are still dependent on the same mundane, paperwork-heavy audit and reporting processes of previous decades. The time and cost to build a PCI, FISMA or HIPAA compliant system is no small feat, even for large enterprises, due to the resources required to develop and maintain the documentation and artifacts that must be continuously audited by a third party.

To address these requirements, Docker has collaborated with the National Institute of Standards and Technology (NIST), and today, we are excited to announce that Docker is fully embracing Continue reading

A Secure Supply Chain for Kubernetes

With KubeCon EU happening in Copenhaguen, we looked back at the most popular posts with our readers on Docker and Kubernetes. For those of you that have yet to try Docker EE 2.0, this blog highlights how Docker EE 2.0 provides a secure supply chain for Kubernetes.

The GA release of the Docker Enterprise Edition (Docker EE) container platform last month integrates Kubernetes orchestration, running alongside Swarm, to provide a single container platform that supports both legacy and new applications running on-premises or in the cloud. For organizations that are exploring Kubernetes or deploying it in production, Docker EE offers integrated security for the entire lifecycle of a containerized application, providing an additional layer of security before the workload is deployed by Kubernetes and continuing to secure the application while it is running.

Mike Coleman previously discussed access controls for Kubernetes. This week we’ll begin discussing how Docker EE secures the Kubernetes supply chain.

What is a Software Supply Chain?

When you purchase something from a retail store, there is an entire supply chain that gets the product from raw materials to the manufacturer to you. Similarly, there is a software supply chain that takes an application from Continue reading

Docker Government Summit 2018

Docker Government Summit

This year’s summit reflected what is top of mind for government organizations, namely IT modernization and what that means for infrastructure, applications, data and the workforce. As mentioned in the keynote address, the line between government IT and private sector IT is blurring now more than ever. From the priorities outlined in the White House IT Modernization Report to the discussions at the recent IT modernization summit, the themes focus on results of better customer service and better stewardship of tax dollars.

Better customer service translates into improving existing services, delivering new services and increasing transparency. To that end, government organizations are taking cues from industry to see how the latest technology and best practices can be applied and adapted to meet the added requirements of government.  The agenda featured speakers from government agencies, higher ed, system integrators and industry partners providing practical insight from their own transformation initiatives and deep dives into the modern technology stack.

Watch these featured videos from the event:

  • General Session: Banjot Chanana, Docker Senior Director Enterprise Product
  • Fireside Chat: Nick Sinai, Insight Ventures Partner and David Shive, GSA CIO
  • Case Study: Arjuna Rivera, Lockheed Martin i2Labs Lead

Learn Docker Plaform best practices with Free Hands-On Labs and Workshops at DockerCon 2018

According to a recent stackoverflow report, the Docker Platform is in the top 10 skills to learn if you want to advance in a career in tech. So where do I go to start learning Docker you may ask?  Well the good news is that we now have free workshops and hands-on Labs included as part of your DockerCon 2018 ticket.

The conference workshops will focus on a range of subjects from migrating .NET or Java apps to the Docker platform to deep dives on container monitoring and logging, networking, storage and security. Each workshop is designed to give you hands-on instructions and guidance on key container notions and mentoring by Docker Engineers and Docker Captains. The workshops are a great opportunity to zoom in a specific aspects on the Docker platform. Here is the list of free workshops available (click on the links to see the full abstracts):

Docker for Desktop is Certified Kubernetes

Certified KubernetesCertified Kubernetes

“You are now Certified Kubernetes.” With this comment, Docker for Windows and Docker for Mac passed the Kubernetes conformance tests. Kubernetes has been available in Docker for Mac and Docker for Windows since January, having first being announced at DockerCon EU last year. But why is this important to the many of you who are using Docker for Windows and Docker for Mac?

Kubernetes is designed to be a platform that others can build upon. As with any similar project, the risk is that different distributions vary enough that applications aren’t really portable. The Kubernetes project has always been aware of that risk – and this led directly to forming the Conformance Working Group. The group owns a test suite that anyone distributing Kubernetes can run, and submit the results for to attain official certification. This test suite checks that Kubernetes behaves like, well, Kubernetes; that the various APIs are exposed correctly and that applications built using the core APIs will run successfully. In fact, our enterprise container platform, Docker Enterprise Edition, achieved certification using the same test suite  You can find more about the test suite at

This is important for Docker for Windows and Docker for Continue reading

Interview with Michael Crosby, the OCI Technical Oversight Board Chairman

Open Container Initiative

Last month the Linux Foundation announced the 2018 Open Container Initiative (OCI) election results of the Technical Oversight Board (TOB). Members of the TOB then voted to elect our very own Michael Crosby as the new Chairman. The result of the election should not come as a surprise to anyone in the community given Michael’s extensive contributions to the container ecosystem.

Back in February 2014, Michael led the development of libcontainer, a Go library that was developed to access the kernel’s container APIs directly, without any other dependencies. If you look at this first commit of libcontainer, you’ll see that the JSONspec is very similar to the latest version of the 1.0 runtime specification.

In the interview below, we take a closer look at Michael’s contributions to OCI, his vision for the future and how this benefits all Docker users.

Why are you excited about your new role as chairman of OCI’s TOB ?

I think that it is important to be part of the TOB to ensure that the specifications that have been created are generally useful and not specific to any one use case. I also feel it is important to ensure that the specifications are stable so that Continue reading

Scalable, Flexible Networking Included in Docker Enterprise Edition 2.0



Docker EE Calico

Docker believes in making technology easy to use and accessible and that approach also extends to our enterprise-ready container platform. That means providing out-of-the-box integrations to key extensions of the platform that enterprise organizations require, but also making it possible to swap these built-in solutions with other tools as desired.

Docker Enterprise Edition 2.0, integrates Kubernetes to our platform and delivers the only Kubernetes platform that can be deployed across multiple clouds and multiple operating systems. As part of this release, we have included Project Calico by Tigera as the “batteries included” Kubernetes CNI plug-in for a highly scalable, industry-leading networking and routing solution.

Why Project Calico?

While we support our customers using their preferred CNI plug-in, we chose to integrate Project Calico for our built-in solution because it aligns well with our design objectives for Docker EE 2.0:

    • Choice & Flexibility for Different Deployment Models: Enterprise organizations are largely pursuing hybrid and multi-cloud strategies and we want to ensure that you have the flexibility to operate Docker EE in any environment. The Tigera team behind Project Calico has worked closely with all the major cloud providers to ensure that Calico works well with their Continue reading

Running Docker on Docker Enterprise Edition 2.0

Did you know that Docker Hub has millions of users pulling roughly one billion container images every two weeks — and it all runs on Docker Enterprise Edition?

Docker Enterprise Edition 2.0 may now be available to commercial customers who require an enterprise-ready container platform, but the Docker operations team has already been using it in production for some time. As part of our commitment to delivering high quality software that is ready to support your mission-critical applications, we leverage Docker Enterprise Edition 2.0 as the platform behind Docker Hub and our other SaaS services, Docker Store, and Docker Cloud.

Some organizations call it “dogfooding;” some call it “drinking your own champagne.” Whatever you call it, the importance of this program is to be fully invested in our own container platform and share in the same operational experiences as our customers.

Our Migration to Kubernetes

One of the main features of this latest release is the integration of Kubernetes so we wanted to make sure we are leveraging this capability. Working closely with our SaaS team leads, we chose a few services to migrate to Kubernetes while keeping others on Swarm.

For people already running Docker EE, Continue reading

Announcing Docker Enterprise Edition 2.0


We are excited to announce Docker Enterprise Edition 2.0 – a significant leap forward in our enterprise-ready container platform. Docker Enterprise Edition (EE) 2.0 is the only platform that manages and secures applications on Kubernetes in multi-Linux, multi-OS and multi-cloud customer environments. As a complete platform that integrates and scales with your organization, Docker EE 2.0 gives you the most flexibility and choice over the types of applications supported, orchestrators used, and where it’s deployed. It also enables organizations to operationalize Kubernetes more rapidly with streamlined workflows and helps you deliver safer applications through integrated security solutions. In this blog post, we’ll walk through some of the key new capabilities of Docker EE 2.0.

Eliminate Your Fear of Lock-in

As containerization becomes core to your IT strategy, the importance of having a platform that supports choice becomes even more important. Being able to address a broad set of applications across multiple lines of business, built on different technology stacks and deployed to different infrastructures means that you have the flexibility needed to make changes as business requirements evolve. In Docker EE 2.0 we are expanding our customers’ choices in a few ways:

It’s Back… The Contribute and Collaborate track returns to DockerCon 2018

A significant number of Docker early adopters, advanced container users and Open Source lovers come to DockerCon to contribute to open source projects and collaborate on technical system implementations. Last year, these activities were taking place at the Moby Summit scheduled on the last day of the conference. Listening to feedback from attendees who expressed interest in participating in such activities earlier in the week, we’ve decided to bring back the Contribute & Collaborate track to the main conference days!

DockerCon Contribute & Collaborate

The goal of this track is to raise awareness and educate users around the upstream components of the Docker Platform, provide a path for new contributors and unleash new opportunities for innovation and collaboration within the broader Cloud Native and Open Source communities.

This track is organized in 4 half days (one for each of the categories below). Each will start by a series of lightning talks during which maintainers will be introducing their projects and doing a brief demo. We’ll then break into smaller groups for roundtables and informal, interactive Birds-of-a-Feather discussions with maintainers. This time will be a great opportunity to collaborate with peers who share the same interest, ask questions to maintainers, get insights into project roadmaps Continue reading

Video Series: Modernizing Java Apps for Developers Part 5

Moving a monolithic application to a modern cloud architecture can be difficult and often result in a greenfield development effort. However, it is possible to move towards a cloud architecture using Docker Enterprise Edition (EE) with no code changes and gain portability, security and efficiency in the process.

To conclude the series In part 5, I use the message service’s REST endpoint to replace one part of the application UI with a Javascript client. The original application client UI was written in Java Server Pages (JSP) so that any UI changes required the application to be recompiled and redeployed. I can use modern web tools and frameworks such as React.js to write a new client interface. I’ll build the new client using a multi-stage build and deploy it by adding the container to the Docker Compose file. I’ll also show how to deploy the entire application from your development to Docker EE to make it available for testing.

Modernizing Java Apps for Developers shows how to take an existing Java N-tier application and run it in containers using the Docker platform to modernize the architecture. The source code for each part of this series is available on github and Continue reading
