Your Docker Agenda for JavaOne
If you are one of the thousands that will be in San Francisco for JavaOne Oct 1-5th, don’t miss the opportunity to level-up your knowledge around container technology and Docker Community and Enterprise Edition. We’ve listed our must-attend sessions below:
Monday, October 2nd
Monday, Oct 02, 11:00 a.m. – 11:45 a.m. | Java in a World of Containers [CON4429]
Speakers: Paul Sandoz and Mikael Vidstedt, Oracle
This session explains how OpenJDK 9 fits into the world of containers, specifically how it fits with Docker images and containers. The first part of the session focuses on the production of Docker images containing a JDK. It introduces technologies, such as J-Link, that can be used to reduce the size of the JDK and discusses the inclusion of class-data-sharing (CDS) archives and ahead-of-time (AOT) shared object libraries. The second part describes how the Java process can be a good citizen when running within a Java container and obeying resource limits. The presentation also covers the role of CDS archives and AOT shared object libraries that can be shared across running containers to reduce startup time or memory usage.

Kubernetes 1.8 release integrates with containerd 1.0 Beta
Intent of containerd effort
When containerd was first developed it had two goals. The first was to solve the upgrade problem with running containers and provide a codebase where OCI runtimes, like runc, could be integrated into Docker. However, as needs change in the container space and after speaking with various members of the community at the beginning of this year, we decided to expand the scope of containerd and make it a fully functional container daemon with storage, image distribution and runtime.
containerd fully supports the OCI Runtime and Image specifications that are part of the recently released 1.0 specifications. Additionally, it was important to build a stable runtime for users and platform builders. We wanted containerd to be fully functional; but also, it needed to retain a small core codebase so that it is easy to maintain and support in the long run with an LTS release receiving backported patches on a stable API.
To demonstrate the progress made on the project, Stephen Day presented the current status of containerd 1.0 alpha at the Moby Summit in LA two weeks ago,:

The Docker Modernize Traditional Apps (MTA) Program Adds Microsoft Azure Stack
In April of this year, Docker announced the Modernize Traditional Apps (MTA) POC program with partners Avanade, Booz Allen, Cisco, HPE and Microsoft. The MTA program is designed to help IT teams flip the 80% maintenance to 20% innovation ratio on it’s head. The combination of Docker Enterprise Edition (EE), services and infrastructure into a turnkey program delivers portability, security and efficiency for the existing app portfolio to drive down total costs and make room for innovation like cloud strategies and new app development. The program starts by packaging of existing apps into isolated containers, providing the opportunity to migrate them to new on-prem or cloud environments, without any recoding.
Docker customers have already been taking advantage of the program to jumpstart their migration to Azure and are experiencing dramatically reduced deployment and scaling times — from weeks to minutes — and cutting their total costs by 50% or more.
The general availability of Microsoft Azure Stack provides IT with the ability to manage their datacenters in the same way they manage Azure. The consistency in hybrid cloud infrastructure deployment combined with consistency in application packaging, deployment and management only further enhance operational efficiency. Docker is pleased Continue reading
Exciting new things for Docker with Windows Server 1709
What a difference a year makes… last September, Microsoft and Docker launched Docker Enterprise Edition (EE), a Containers-as-a-Service platform for IT that manages and secures diverse applications across disparate infrastructures, for Windows Server 2016. Since then we’ve continued to work together and Windows Server 1709 contains several enhancements for Docker customers.
Docker Enterprise Edition Preview
To experiment with the new Docker and Windows features, a preview build of Docker is required. Here’s how to install it on Windows Server 1709 (this will also work on Insider builds):
Install-Module DockerProvider Install-Package Docker -ProviderName DockerProvider -RequiredVersion preview
To run Docker Windows containers in production on any Windows Server version, please stick to Docker EE 17.06.
Docker Linux Containers on Windows
A key focus of Windows Server version 1709 is support for Linux containers on Windows. We’ve already blogged about how we’re supporting Linux containers on Windows with the LinuxKit project.
To try Linux Containers on Windows Server 1709, install the preview Docker package and enable the feature. The preview Docker EE package includes a full LinuxKit system (all 13MB of it) for use when running Docker Linux containers.
[Environment]::SetEnvironmentVariable("LCOW_SUPPORTED", "1", "Machine") Restart-Service Docker
To disable, just remove the environment variable:
[Environment]::SetEnvironmentVariable("LCOW_SUPPORTED", Continue reading
Yes to databases in containers – Microsoft SQL Server available on Docker Store
Microsoft SQL Server 2017 is now available for the first time on multiple platforms: Windows, Linux and Docker. Your databases can be in containers with no lengthy setup and no prerequisites, and using Docker Enterprise Edition (EE) to modernize your database delivery. The speed and efficiency benefits of Docker and containerizing apps that IT Pros and developers have been enjoying for years are now available to DBAs.
Try the Docker SQL Server lab now and see how database containers start in seconds, and how you can package your own schemas as Docker images.
If you’ve ever sat through a SQL Server install, you know why this is a big deal: SQL Server takes a while to set up, and running multiple independent SQL Server instances on the same host is not simple. This complicates maintaining dev, test and CI/CD systems where tests and experiments might break the SQL Server instance.
With SQL Server in Docker containers, all that changes. Getting SQL Server is as simple as running `docker image pull`, and you can start as many instances on a host as you want, each of them fresh and clean, and tear them back down when you’re done.
Database engines Continue reading
A Day in the Life of a Docker Admin
About two months ago, we celebrated SysAdmin Day and kicked off our learning series for IT professionals. So far we’ve gone through the basics of containers and how containers are delivering value back to the company through cost savings. Now we begin the next stage of the journey by introducing how to deploy and operate containerized applications.
For the next few weeks, we are going to relate typical IT administrative tasks that many of you are familiar with to the tasks of a Docker admin. In the end, containerized applications are still applications and it is still primarily the responsibility of IT to secure and manage them. That is the same regardless of if the application runs in a container or not.
In this “A Day in the LIfe of a Docker Admin” series, we will discuss how common IT tasks translate to the world of Docker, such as:
- Managing .NET apps and migrating them off Windows Server 2008
- How networking with containers work and how to build an agile and secure network for containers
- How to achieve a secure and compliant application environment for any industry
- Integrating Docker with monitoring and logging tools
As a first step, let’s make Continue reading
Get Familiar with Docker Enterprise Edition Client Bundles
Docker Enterprise Edition (EE) is the only Containers as a Service (CaaS) Platform for IT that manages and secures diverse applications across disparate infrastructure, both on-premises and in the cloud.
There’s a little mentioned big feature in Docker Enterprise Edition (EE) that seems to always bring smiles to the room once it’s displayed. Before I tell you about it, let me first describe the use case. You’re a sysadmin managing a Docker cluster and you have the following requirements:
- Different individuals in your LDAP/AD need various levels of access to the containers/services in your cluster
- Some users need to be able to go inside the running containers.
- Some users just need to be able to see the logs
- You do NOT want to give SSH access to each host in your cluster.
Now, how do you achieve this? The answer, or feature rather, is a client bundle. When you do a docker version command you will see two entries. The client portion of the engine is able to connect to a local server AND a remote once a client bundle is invoked.
What is a client bundle?
A client bundle is a group of certificates downloadable directly from the Docker Universal Continue reading
Docker Official Images are now Multi-platform
This past week, Docker rolled out a big update to our Official Images to make them multi-platform aware. Now, when you run docker run hello-world, Docker CE and EE will pull and run the correct hello-world image whether that’s for x86-64 Linux, Windows, ARM, IBM Z mainframes or any other system where Docker runs. With Docker rapidly adding support for additional operating systems (like Windows) and CPU architectures (like IBM Z) this is an important UX improvement.
Docker Official Images are a curated set of container images that include:
- Base operating system images like Ubuntu, BusyBox and Debian
- Ready-to-use build and runtime images for popular programming languages like Go, Python and Java
- Easy-to-use images for data stores such as PostgreSQL, Neo4j and Redis
- Pre-packaged software images to run WordPress, Ghost and Redmine and many other popular open source projects
The official images have always been available for x86-64 Linux. Images for non x86 Linux architectures have also been available, but to be fetched either from a different namespace (docker pull s390x/golang on IBM Z mainframe) or using a different tag (docker pull golang:nanoserver on Windows). This was not the seamless and portable experience Continue reading

Preview: Linux Containers on Windows
Microsoft is getting ready for the next big update for Windows Server (check out today’s complimentary Microsoft blog post) and some of the new features are very exciting for Docker users. One of the most important enhancements is that Docker can now run Linux containers on Windows, using Hyper-V technology.
Running Docker Linux containers on Windows requires a minimal Linux kernel and userland to host the container processes. This is exactly what the LinuxKit toolkit was designed for: creating secure, lean and portable Linux subsystems that can provide Linux container functionality as a component of a container platform.
We’ve been busy prototyping LinuxKit support for Docker Linux containers on Windows and have a working preview for you to try. This is still a work in progress, and requires either the recently announced “Windows Server Insider” or Windows 10 Insider builds.
Running Docker Linux Containers on Windows with LinuxKit
The instructions below have been tested on Windows 10 and Windows Server Insider builds 16278 and 16281.
Be sure to install Docker for Windows (Windows 10) or Docker Enterprise Edition (Windows Server Insider) before starting.
Setup Docker and LinuxKit
A preview build of LinuxKit is available by simply running Continue reading
Docker Enterprise Edition for Linux on IBM Z (yes, mainframe!)
Recently we released a new version of Docker Enterprise Edition featuring expansion of the multi-architecture capabilities from Linux to Windows Server and now the IBM Z mainframe platform. Enterprise IT architecture is complex and diverse and include workloads across different server hardware types and operating systems.
Docker and IBM have partnered together to deliver the support for Red Hat Enterprise Linux, Ubuntu and SUSE Linux Enterprise Server for IBM Z (x390x) systems as certified infrastructure for Docker Enterprise Edition. This first release features support for the the IBM Z product family.
Why bring Docker containers and mainframe systems together? Enterprises across industries like financial services, government, manufacturing and more use mainframe systems for many high throughput applications. Many organizations recognize that these applications are at the core of their systems but rewriting and refactoring them for a different platform is expensive and time-consuming. By wrapping them in a container, organizations can make these applications easier to maintain and update while bringing them into the same software supply chain as other x86 applications
Multi-Architecture Support for Mainframe Systems
Docker Enterprise Edition allows for the same orchestration, security model, supply chain and integrated management that can be applied across a broader range Continue reading
Secure Multi-Tenancy at Scale with Docker Enterprise Edition
With the latest release of Docker Enterprise Edition (EE), enterprise organizations are able to extend the benefits of containers across their entire application portfolio. Docker EE enables rapid modernization of traditional Windows and Linux applications as well as Linux applications running on IBM Z mainframes. By addressing all of these applications, Docker EE provides the opportunity to standardize around a common packaging format for greater portability, agility, and with an additional layer of security, resulting in more teams bringing their workloads into Docker EE.
The key to operating this diverse environment is to have a way to secure and isolate the applications and the multiple teams who build, ship, and deploy them. This release of Docker Enterprise Edition makes it possible for organizations to modernize traditional applications of every variety and to do so in a secure manner that aligns to complex organizational needs.
Building a Secure Software Supply Chain for Windows Applications
Windows applications make up about half of all enterprise applications. Docker has been working closely with Microsoft to ensure that the same security benefits that are available to Linux containers are also available to Windows Server containers. When Windows containers are managed with Docker EE, organizations Continue reading
Docker in the Enterprise Showcased at VMworld 2017
Last week, in the blistering heat of Las Vegas, Docker had a chance to interact with thousands of VMworld attendees to talk about containers. The message we heard again and again was that those in charge of infrastructure and virtualization are now being asked to manage containers. Sometimes it is being driven by developer teams that are already using Docker, but sometimes it is the infrastructure teams who recognize the benefits of moving applications to containers for easier maintenance and operations as well as cost savings. With Docker Enterprise Edition (EE), we have a solution that is designed to let IT secure and manage containerized applications.
Learn More About Docker for VMware Admins
If you’re interested in learning more about how Docker EE allows IT to improve operations, move workloads to the cloud and increase application agility all while saving costs, we’re happy to be partnering with the VMware User Group (VMUG) to deliver a webcast tomorrow. Register now to see how Docker EE is being used by some of the world’s largest container deployments, how Docker works with Windows applications or to clarify any confusion you may have about how Docker containers and VMs work together.

A: As a form of packaging Continue reading
An Inside Look at the Docker Captains Program
Since launching the Docker Captains over a year ago, we’ve received a lot of questions: What is a Docker Captain? What do Captains do? How do I become a Captain? So who better to answer that than the Docker Captains themselves? At DockerCon Austin, we asked the Docker Captains to share their favorite thing about wearing the Captain’s hat.
What is a Captain?
Captains are Docker experts that are leaders in their communities, organizations or ecosystems. As Docker advocates, they are committed to sharing their knowledge and do so every chance they get!
What do Captains do?
Captains are advisors, ambassadors, coders, contributors, creators, tool builders, speakers, mentors, maintainers and super users and are required to be active stewards of Docker in order to remain in the program.
In addition to sharing their knowledge with the community, Captains provide insight and feedback to Docker. They have direct access to our technical teams, and are first to hear about and try upcoming features, product releases and big announcements.
What do Captains get?
In return for their efforts, Captains get access to the existing captains community and Docker staff. They get ongoing training, private briefings and Slack chat channels where Captains Continue reading
Video Series: Modernizing .NET Apps for IT Pros
This is a new 5-part video series in Docker’s Modernize Traditional Apps (MTA) program, aimed at Microsoft IT Pros. The video series shows you how to move a .NET 3.5 app from Windows Server to a Windows Docker container and deploy it to a scalable, highly-available environment in the cloud – without any changes to the app.
Part 1 introduces the series, explaining what is meant by “traditional” apps and the problems they present. Traditional apps are built to run on a server, rather than on a modern application platform. They have common traits, like being complex to manage and difficult to deploy. A portfolio of traditional applications tends to under-utilize its infrastructure, and over-utilize the humans who manage it. Docker Enterprise Edition (EE) fixes that, giving you a consistent way to package, release and manage all your apps, without having to re-write them.
Part 2 shows how easy it is to move traditional apps to Docker EE. I start with an ASP.NET 3.5 WebForms application running on Windows Server 2003, and use Image2Docker to extract the app and package it as a Docker image. Then I run the application in a Docker Windows container on Continue reading
