Test Drive Docker Enterprise Edition at VMworld 2017
Docker will be at VMworld 2017 next week (August 27-31) in Las Vegas to highlight new developments with Docker Enterprise Edition (EE), the only Container as a Service (CaaS) platform for managing and securing Windows, Linux and mainframe applications across any infrastructure, both on premises and in the cloud.
Stop by Booth #1206 to learn more about:
- How VMs and containers work together for improved application lifecycle management
- How containers and Docker EE can help IT with day-to-day maintenance and operations tasks
- How IT can lead modernization efforts with Docker EE and become drivers of innovation in their organizations
Just as VMware vSphere simplified the management of VMs and made virtualization the de facto standard inside the data center, Docker is driving containerization of your entire application portfolio with Docker EE and helping organizations like yours to achieve their cloud and app modernization goals without requiring you to change how you operate.
Test Drive Docker EE in the Booth
Don’t miss the chance to get hands-on experience with Docker with our in-booth labs. Led by Docker experts, you will get to see for yourself how Docker brings all applications—traditional and cloud-native, Windows and Linux, on-prem and in Continue reading
My Three Favorite New Features in Docker Enterprise Edition
I’ve been at Docker for just over two years now, and I’ve worked with every version of Docker Enterprise Edition (née Docker Datacenter) since before there even was a Docker Enterprise Edition (EE). I’m more excited about this new release than any previous release.
There are several new features that are going to ease the management of your applications (both traditional and cloud-native) wherever you need them to run: the cloud or the data center, virtual or physical, Linux or Windows – and now even IBM Z mainframes.
It would take too long to discuss all of the new features, so with that in mind, I’m going to talk about my three favorite features in Docker EE 17.06.
Hybrid-OS Clusters
Docker and Microsoft introduced support for Windows Server containers last fall. This was a major milestone that helped Docker move towards the goal of embracing apps across the entirety of the data center. With this latest release Docker extends hybrid OS operations even further: IT admins can now build and manage clusters comprised of Linux, Windows Server 2016, and IBM Z mainframes – all from the same management plane. This means you can manage applications comprised of both Windows Continue reading
Docker is Headed to Gartner Catalyst 2017
The Docker team will be in sunny San Diego, CA, August 21-23 for Gartner Catalyst. Come by and visit us in Booth #508 to meet with our Docker Enterprise Edition (EE) experts, see a demo of Docker EE, and ask us any questions you may have before and after any of the Gartner sessions on Docker and containers. Better yet, schedule a meeting with us and we’ll not only answer all your questions, you will also get a special gift.
This year’s Catalyst event includes an entire topic dedicated to Docker and containers, which you can find by looking for the topic “Docker & Containers” in the schedule builder. If you are still trying to separate all the fact from fiction about Docker and want a specific recommendation, there is a great Tech Demo session by Gartner analyst Richard Watson we think you might like titled Seven Docker & Container Myths We Need To Bust.
We hope you will join us at Gartner Catalyst to get the latest research on the next big trends for IT, but if you are not in San Diego, we hope to see you at one of these other upcoming events:

Announcing the New Release of Docker Enterprise Edition
We are excited to share the new release of Docker Enterprise Edition. By supporting IBM Z and Windows Server 2016, this release puts us further in the lead with the first Containers-as-a-Service (CaaS) solution in the market for the modernization of all applications without disruption to you and your IT environment.
Docker Enterprise Edition (EE) 17.06 embraces Windows, Linux and Linux-based mainframe applications, bringing the key benefits of CaaS to the enterprise application portfolio. Most enterprises manage a diverse set of applications that includes both traditional applications and microservices, built on Linux and Windows, and intended for x86 servers, mainframes, and public clouds. Docker EE unites all of these applications into single platform, complete with customizable and flexible access control, support for a broad range of applications and infrastructure, and a highly automated software supply chain. These capabilities allow organizations to easily layer Docker EE onto existing processes and workflows, aligning to existing organizational structures while delivering improved resource utilization and reduced maintenance time.
This release includes UCP 2.2 and DTR 2.3 and establishes Docker EE as a key IT platform for both new application development as well as application modernization across both on-premises and Continue reading

Be a Budget Hero with Docker Enterprise Edition
We recently started a multi-part learning series for SysAdmins and IT professionals called IT Starts With Docker. We started with the basics, covering container technology and Docker solutions for the enterprise. Now, we shift to the important question: Is it worth your time and your company’s investment to further explore Docker Enterprise Edition (EE)?
The resounding answer to that question is YES. IT teams who have adopted Docker EE are finding it faster and easier to deploy and maintain their applications, plus drive better infrastructure utilization, all without touching the underlying code. Developer teams are realizing productivity gains of their own by being able to onboard new developers faster, shortening the cycles from development to production, and elimination of the burdensome “it worked on my machine” problems.
Try the simple ROI calculator for yourself. It takes just a couple of minutes and allows you to estimate your own savings with Docker EE and how you can become the budget hero of your department. Then, register for our live webinar on Tuesday, August 15th, The Business Value of Docker, where we will outline how organizations like your own are saving 50% on their total costs with Docker EE.

What is containerd ?
We have done a few talks in the past on different features of containerd, how it was designed, and some of the problems that we have fixed along the way. Containerd is used by Docker, Kubernetes CRI, and a few other projects but this is a post for people who may not know what containerd actually does within these platforms. I would like to do more posts on the featureset and design of containerd in the future but for now, we will start with the basics.
I think the container ecosystem can be confusing at times. Especially with the terminology that we use. Whats this? A runtime. And this? A runtime… containerd as the name implies, not contain nerd as some would like to troll me with, is a container daemon. It was originally built as an integration point for OCI runtimes like runc but over the past six months it has added a lot of functionality to bring it up to par with the needs of modern container platforms like Docker and Kubernetes.
Since there is no such thing as Linux containers in the kernelspace, containers are various kernel features tied together, when you are building a large Continue reading
Docker 101: Introduction to Docker webinar recap
Docker is standardizing the way to package applications, making it easier for developers to code and build apps on their laptop or workstation and for IT to manage, secure and deploy into a variety of infrastructure platforms
In last week’s webinar, Docker 101: An Introduction to Docker, we went from describing what a container is, all the way to what a production deployment of Docker looks like, including how large enterprise organizations and world-class universities are leveraging Docker Enterprise Edition (EE) to modernize their legacy applications and accelerate public cloud adoption.
If you missed the webinar, you can watch the recording here:
We ran out of time to go through everyone’s questions, so here are some of the top questions from the webinar:
Q: How does Docker get access to platform resources, such as I/O, networking, etc. Is it a type of hypervisor?
A: Docker EE is not a type of hypervisor. Hypervisors create virtual hardware: they make one server appear to be many servers but generally know little or nothing about the applications running inside them. Containers are the opposite: they make one OS or one application server appear to be many isolated instances. Containers explicitly must know the Continue reading

IT Starts with Docker
Happy SysAdmin Day! Cheers to all of you who keep your organizations running, keep our data secure, respond at a moment’s notice and bring servers and apps back to life after a crash. Today we say, “Thank You!”
Anniversaries are a great time to reflect on accomplishments of the last year: the projects you’ve completed, the occasions you’ve saved your company money or time, the new technology you’ve learned. In a role like IT, so much can change each year as technology progresses and becomes more challenging to stay ahead of that curve. So this SysAdmin Day, we at Docker want to congratulate your past successes and prepare you for the year to come.
Containers are not just for developers anymore and Docker is the standard for packaging all kinds of applications – Windows, Linux, traditional, and microservices. Over the next few months, we’ll be covering how SysAdmins like yourself are enabling their organizations to innovate faster while saving their companies’ money by embracing containers with Docker Enterprise Edition.
Sign up here to start your journey and learn how IT Starts with Docker.
This multi-part series will include:

Modernize Traditional Applications by Docker Webinar Recap
IT organizations continue to spend 80% of their budget on simply maintaining their existing applications while only spending 20% on innovation. That ratio has not changed over the last 10 years, and yet, there’s no shortage of pressure to innovate. Whether it comes directly from your customers asking for new features, or it comes from your management chain, the story is the same; you have to do more with less.
Thankfully, there is Modernize Traditional Applications from Docker. Where you can take your existing legacy applications, the same ones that underline your business, and make them 70% more efficient, more secure, and best of all – portable across any infrastructure. And you can do all of that, without touching a single line of the underlying application code. Sounds too good to be true right? Well, watch the recording below and you’ll see that it’s absolutely possible.
Give your legacy application modern capabilities without touching code using Docker EE by way of…

Docker Community Spotlight: Adina-Valentina Radulescu
Adina-Valentina Radulescu, a DevOps/Integration Engineer for Pentalog Romania, has been organizing meetups for not one but two meetup groups.
In February of last year, Adina founded Docker Brasov and Docker Timisoara, and has since done an amazing job creating and fostering a sense of belonging in her community. This month, we’re happy to shine the community spotlight on Adina to learn more about her Docker story.
Tell us about your first experience with Docker.
The first time I heard about Docker was back in 2014. I played around with Docker and I was impressed with the simplicity of integration so I wanted to learn more. I was able to attend DockerCon EU in 2015 in Barcelona where I completed some labs and attended the talks to learn as much as I could about Docker. It was a powerful feeling.
Why did you start Docker Brasov and Docker Timisoara?
I wanted to have a Docker sharing exchange experience when I get back in Romania. I relocated from Timisoara to a beautiful mountain city, Brasov. In Timisoara, I knew people and companies. In Brasov, I knew almost no one. This is why I decided to start the two groups so I Continue reading
Docker Spearheads OCI Release of v1.0 Runtime and Image Format Specifications
Today marks an important milestone for the Open Container Initiative (OCI) with the release of the OCI v1.0 runtime and image specifications – a journey that Docker has been central in driving and navigating over the last two years. It has been our goal to provide low-level standards as building blocks for the community, customers and the broader industry. To understand the significance of this milestone, let’s take a look at the history of Docker’s growth and progress in developing industry-standard container technologies.
The History of Docker Runtime and Image Donations to the OCI
Docker’s image format and container runtime quickly emerged as the de facto standard following its release as an open source project in 2013. We recognized the importance of turning it over to a neutral governance body to fuel innovation and prevent fragmentation in the industry. Working together with a broad group of container technologists and industry leaders, the Open Container Project was formed to create a set of container standards and was launched under the auspices of the Linux Foundation in June 2015 at DockerCon. It became the Open Container Initiative (OCI) as the project evolved that Summer.
Docker contributed runc, a reference implementation for the Continue reading
Demystifying the Open Container Initiative (OCI) Specifications
The Open Container Initiative (OCI) announced the completion of the first versions of the container runtime and image specifications this week. The OCI is an effort under the auspices of the Linux Foundation to develop specifications and standards to support container solutions. A lot of effort has gone into the building of these specifications over the past two years. With that in mind, let’s take a look at some of the myths that have arisen over the past two years.
Myth #1: The OCI is a replacement for Docker
Standards are important, but they are far from a complete production platform. Take for example, the World Wide Web. It has evolved over the last 25 years and was built on core dependable standards like TCP/IP, HTTP and HTML. Using TCP/IP as an example, when enterprises coalesced around TCP/IP as a common protocol, it fueled the growth of routers and in particular – Cisco. However, Cisco became a leader in its market by focusing on differentiated features on its routing platform. We believe the parallel exists with the OCI specifications and Docker.
Docker is a complete production platform for developing, distributing, securing and orchestrating container-based solutions. The OCI specification is used Continue reading
Docker on Windows Webinar Q&A
Recently I presented Docker on Windows: from 101 to Modernizing .NET Apps, a live webinar on using Docker with Windows, and running .NET Framework apps in containers. The session was recorded and you can watch it on the Docker YouTube channel:
I start with the basics of Windows Docker containers, showing how to you can run containers from public images, and write Dockerfiles to package your own apps to run in containers.
Then I move onto Dockerizing a traditional ASP.NET WebForms app, showing you how to take existing apps and run them in Docker with no code changes, and then use the Docker platform to modernize the app – breaking features out of the monolithic codebase, running them in separate containers and using Docker to connect them.
I maxed out the session time (just like Mike with his Docker for the Sysadmin webinar), so here are the answers to questions raised in the session.
Q: We have several servers hosting our frontend, some as middle tier hosting the services and we have some for the database. Shall we have a container for each service?
A: Docker doesn’t mandate any particular design, you can architect your move to Continue reading
The best way to learn Docker for Free: Play-With-Docker (PWD)
Last year at the Distributed System Summit in Berlin, Docker captains Marcos Nils and Jonathan Leibiusky started hacking on an in-browser solution to help people learn Docker. A few days later, Play-with-docker (PWD) was born.
PWD is a Docker playground which allows users to run Docker commands in a matter of seconds. It gives the experience of having a free Alpine Linux Virtual Machine in browser, where you can build and run Docker containers and even create clusters in Docker Swarm Mode. Under the hood Docker-in-Docker (DinD) is used to give the effect of multiple VMs/PCs. In addition to the playground, PWD also includes a training site composed of a large set of Docker labs and quizzes from beginner to advanced level available at training.play-with-docker.com.
In case you missed it, Marcos and Jonathan presented PWD during the last DockerCon Moby Cool Hack session. Watch the video below for a deep dive into the infrastructure and roadmaps.
Over the past few months, the Docker team has been working closely with Marcos, Jonathan and other active members of the Docker community to add new features to the project and Docker labs to the training section.

Moby Summit alongside Open Source Summit North America
Since the Moby Project introduction at DockerCon 2017 in Austin last April, the Moby Community has been hard at work to further define the Moby project, improve its components (runC, containerd, LinuxKit, InfraKit, SwarmKit, Libnetwork and Notary) and fine processes and clear communication channels.
All project maintainers are developing these aspects in the open with the support of the community. Contributors are getting involved on GitHub, giving feedback on the Moby Project Discourse forum and asking questions on Slack. Special Interest Groups (SIGs) for the Moby Project components have been formed based on the Kubernetes model for Open Source collaboration. These SIGs ensure a high level of transparency and synchronization between project maintainers and a community of heterogeneous contributors.
In addition to these online channels and meetings, the Moby community hosts regular meetups and summits. Check out the videos and slides from the last DockerCon Moby May Summit and June Moby Summit to catch up on the latest project updates. The Moby Summit page on the Moby website contains the agenda and registration link for next Moby summit, as well as recaps of previous summit.
The next Moby Summit will take Continue reading
Securing the AtSea App with Docker Secrets
Passing application configuration information as environmental variables was once considered best practice in 12 factor applications. However, this practice can expose information in logs, can be difficult to track how and when information is exposed, third party applications can access this information. Instead of environmental variables, Docker implements secrets to manage configuration and confidential information.
Secrets are a way to keep information such as passwords and credentials secure in a Docker CE or EE with swarm mode. Docker manages secrets and securely transmits it to only those nodes in the swarm that need access to it. Secrets are encrypted during transit and at rest in a Docker swarm. A secret is only accessible to those services which have been granted explicit access to it, and only while those service tasks are running.
The AtSea Shop is an example storefront application that can be deployed on different operating systems and can be customized to both your enterprise development and operational environments. The previous post showed how to use multi-stage builds to create small and efficient images. In this post, I’ll demonstrate how secrets are implemented in the application.
Creating Secrets
Secrets can be created using the command line or with a Compose file. The AtSea Continue reading
Docker for the SysAdmin Webinar Q&A
On June 27th I presented a webinar on “Docker for the SysAdmin”. The webinar was driven by a common scenario I’m seeing: A sysadmin is sitting at her desk minding her own business when a developer walks in and says “here’s the the new app, it’s in a Docker image. Please deploy it ASAP”. This session is designed to help provides some guidance on how sysadmins should think about managing Dockerized applications in production.
In any case, I was a bit long-winded (as usual), and didn’t have time to answer all the Q&A during the webinar (and there were quite a few).
So, as promised, here are all the questions from that session, along with my answers. If you need more info, hit me up on Twitter: @mikegcoleman
————
Q: I am planning an application deployment and want to use Docker. What cloud would you recommend at the moment? I have GCP, Azure, AWS under my belt. 1) TCO 2) Performance ?
A: Answering that would require me to understand your application on a pretty deep level, so I can’t really provide a specific response. I will say that if you choose one cloud provider today, and realize that Continue reading
