Scalable, Flexible Networking Included in Docker Enterprise Edition 2.0

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:

• Multi-Linux, Multi-OS, Continue reading

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!

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

Docker Registry API to be standardized in OCI

We are excited to announce that the Docker Registry HTTP API V2 specification will be adopted in the Open Container Initiative (OCI), the organization under the Linux Foundation that provides the standards that fuel the containerization industry. The Docker team is proud to see another aspect of our technology stack become a de-facto standard. As we’ve done with our image format, we are happy to formally share and collaborate with the container ecosystem as part of the OCI community. Our distribution protocol is the underpinning of all container registries on the market and is so robust that it is leveraged over a billion times every two weeks as container content is distributed across the globe.

What does this protocol do?

Putting the protocol into perspective, part of the core functionality of Docker is the ability to push and pull images. From the first “Hello, World” moment, this concept is introduced to every user and is a large part of the Docker experience. While we normally sit back in our armchairs and marvel at this magical occurence, the amount of design and consideration that has gone into that simple capability can easily be overlooked.

When Docker was first released, the team Continue reading

Video Series: Modernizing Java Apps for Developers Part 4

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.

Part 4 takes advantage of the messaging service I added in part 3. In this installment, I’ll add self service analytics powered by the open source Elasticsearch / Kibana stack. The reporting database and analytics UI run in containers and the worker is updated to also store data in Elasticsearch. The Docker platform supports adding new components to a running deployment without shutting down the application containers that are currently running. You’ll learn how Docker lets you add new capabilities to the application with zero downtime in production.

Webinar Recap: The Docker Platform on Windows – from 101 to Modernizing .NET Apps

Our live Docker webinars are always hugely popular. Last month we hosted a session on Docker and Windows containers, covering everything from the basics to how you can use the  Docker platform (Docker Enterprise Edition and Docker Desktop)  to modernize existing .NET apps and move them to the cloud.

The recording is available now – it clocks in at 60 minutes and has lots of demos showing you how to build and run Windows applications in containers with Docker for Windows:

The sample code, Dockerfiles and Docker Compose files for all the demos are here on GitHub.

In fact there were so many demos, I ran out of time for the Q&A part – so here are the unanswered questions we had from viewers:

Q. Are there any best practices or tutorial to architect sql databases in containers? What about data persistence, database references etc? How can we use SSDT with containers?

SQL Server running in a container is just like any remote SQL Server – you can connect with SSDT or Visual Studio or VS Code or any SQL client. There’s a good SQL Server in Docker tutorial on GitHub which walks through the build and deployment process with containers, and Continue reading

Improved Docker Container Integration with Java 10

Many applications that run in a Java Virtual Machine (JVM), including data services such as Apache Spark and Kafka and traditional enterprise applications, are run in containers. Until recently, running the JVM in a container presented problems with memory and cpu sizing and usage that led to performance loss. This was because Java didn’t recognize that it was running in a container. With the release of Java 10, the JVM now recognizes constraints set by container control groups (cgroups). Both memory and cpu constraints can be used manage Java applications directly in containers, these include:

• adhering to memory limits set in the container
• setting available cpus in the container
• setting cpu constraints in the container

Java 10 improvements are realized in both Docker for Mac or Windows and Docker Enterprise Edition environments.

Container Memory Limits

Until Java 9 the JVM did not recognize memory or cpu limits set by the container using flags. In Java 10, memory limits are automatically recognized and enforced.

Java defines a server class machine as having 2 CPUs and 2GB of memory and the default heap size is ¼ of the physical memory. For example, a Docker Enterprise Edition installation has 2GB of memory and Continue reading

Au revoir

Today I’m announcing my departure from Docker, the company I helped create ten years ago and have been building ever since. A founder’s departure is usually seen as a dramatic event. Sadly, I must report that reality is far less exciting in this case. I’ve had many roles at Docker over the years, and today I have a new, final one – as an active board member, a major shareholder and, I expect, a high maintenance Docker user. But I will no longer be part of day-to-day operations. Instead, after obsessing for so many years over my own ideas, I am rediscovering the joys of putting myself at the service of others – my friends, my family, and the brilliant entrepreneurs I’ve been lucky enough to advise and invest in over the years. Over the coming months I plan to use my experience to help them in any way I can.

This transition is simply another chapter in a long story of change, growth, hard work… and a lot of luck.

Ten years ago, I quit my job, returned to live with my mother in Paris and, together with my friends Kamel Founadi and Sebastien Pahl, started a company called Continue reading

Video Series: Modernizing Java Apps for Developers Part 3

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 with no code changes and gain choice , security and operational agility in the process.

Part 3 of the series begins the modernization process. I’ll take one aspect of the current application and break it out into a microservice. As written, the application writes to the database directly, but direct writes to the database can easily overwhelm the application by a large number of requests.

One solution is to implement a messaging queue. As in the part 2, I’ll follow several guidelines:

1. Leave existing code in place.
2. Design the new code as a separate and reusable application
3. Deploy the microservice locally using Docker Enterise Edition
4. Test the code

In this part of the modernization process, I add a message queue comprised of a REST interface that writes to a Redis database. The user data is held in Redis until it’s requested by a worker service that does the write to the database. The message queue uses Spring Boot to implement both the REST interface and the Redis database functions. Continue reading

5 years later, Docker has come a long way

The evolution of Docker: From introducing a container runtime to building an enterprise-ready container platform

Back in March 2013, Docker was introduced publicly for the first time during Docker founder, Solomon Hykes’ lightning talk at PyCon. Since that moment in 2013, Docker has evolved in conjunction with the needs of users and customers to drive innovation around security, orchestration, networking and more. From building out advanced security features across the software supply chain and offering the choice of both Swarm and Kubernetes, to developing Docker for Mac/Windows and the Docker Enterprise Edition (EE) container platform, Docker has come a long way. Now at the age of five, Docker has millions of users and over 450 commercial customers – including hundreds of the world’s largest companies – that rely on Docker EE to power their digital and multi-cloud initiatives.

The history of Docker has shaped where we are today and as we celebrate our 5th birthday this week, we take a look back at the journey that lead us here.

Following the enthusiastic reception at PyCon 2013, Docker’s image format and container runtime quickly emerged as the de facto standard and building block for the community, customers and the broader industry. The Continue reading

Video Series: Modernizing Java Apps for Developers Part 2

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

In the first post in this series, we discussed how you don’t need to do a full re-architecture of your application to microservices when using Docker Enterprise Edition.

In the second installment of the series, I go into the details of containerization of the application. This process builds containers using the application code as-is. I’ll follow three simple rules:

1. Keep the existing architecture
2. Keep the save version of the OS, components and application
3. Keep deployment simple, i.e. static not elastic

I’ll also demonstrate how to use multi-stage build file to compile the code and deploy it to application server container such as Tomcat. It also shows how to deploy the application and database using a Docker Compose file.

A Secure Supply Chain for Kubernetes, Part 2

Two weeks ago we shared how the upcoming release of Docker Enterprise Edition (Docker EE) is able to secure the software supply chain for Kubernetes; just as it does for Docker Swarm through a combination of scanning for vulnerabilities and implementing image promotion policies. In this blog, we’ll take a closer look at another part of this solution – Docker Content Trust and image signing.

When combined with granular Role Based Access Controls [RBAC] and the secure clustering features of Docker EE, organizations get a secure container platform solution that is ready for the enterprise.

Restricting Unverified Kubernetes Content

As discussed in Part 1 of this blog post, organizations typically have a “supply chain” for how applications progress from a developer’s laptop to production, whether that is on-premises or in the cloud. For larger organizations, the team that handles QA and testing is not always the same team that develops the applications. There may also be a separate team that handles staging and pre-production before an application is pushed to production. Since an application can pass through several teams before it gets deployed, it’s important for organizations to be able to validate the source of the application.

Docker Content Trust Continue reading

Video Series: Modernizing Java Apps for Developers Part 1

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 with no code changes and gain portability, security and efficiency in the process.

Containerizing a monolithic application is a great starting point for modernizing application architecture.In many cases this can be done with no code changes at all.  From there, breaking down the application into smaller components makes it easier to deploy updates, introduce new components and manage scale.

This new video series covers modernization for Java applications. It walks through the process of evolving a N-tier Java application to a distributed application running across multiple containers. Docker provides the platform that plugs in and manages all the components into a coherent architecture.

This  series does not cover a full re-architecture to microservices. Shifting to a full microservices approach isn’t right for all applications, and the daunting task of a full rewrite of a monolithic application can be a massive endeavor that takes years to pay-off. Especially if what you have works. This series uses a feature driven approach. I select key features to update, in order to fix Continue reading

Enhanced Layer 7 Routing for Swarm in Docker Enterprise Edition Beta

 The beta release of Docker Enterprise Edition has seen incredible activity. The highlight of the upcoming Docker Enterprise Edition (Docker EE) release is the integration of Kubernetes and bringing all of the advanced security, RBAC and management capabilities of Docker EE to Kubernetes. At the same time, we have been working to improve Swarm, delivering the only container platform that allows you to run both orchestrators in the same cluster. In this blog post, we’ll highlight some the key new capabilities around application-layer (Layer 7) routing and load balancing for Swarm-deployed applications. These enhancements come from the new Interlock 2.0 architecture which provides a highly scalable and highly available routing solution for Swarm. The new architecture brings some additional features to the platform, including path-based routing and SSL termination.

Path-Based Routing

Layer 7 load balancing allows traffic going to host domains like acme.com to be distributed across specific containers in your environment. With path-based routing, traffic headed to sub-domains within acme.com (eg. acme.com/app1 or acme.com/app2) can be separately routed to different sets of containers. This can be especially useful for optimizing application performance by driving different requests to different groups of containers.
