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 Continue reading…

Top 5 blogs of 2017: LinuxKit, A Toolkit for building Secure, Lean and Portable Linux Subsystems

In case you’ve missed it, this week we’re highlighting the top five most popular Docker blogs in 2017. Coming in the third place is the announcement of LinuxKit, a toolkit for building secure, lean and portable Linux Subsystems.   LinuxKit includes the tooling to allow building custom Linux subsystems that only include exactly the components the runtime platform requires. All system services are containers that can be replaced, and everything that is not required can be removed. All components can be substituted with ones that match specific needs. It is a kit, very much in the Docker philosophy of batteries included but swappable. LinuxKit is an open source project available at https://github.com/linuxkit/linuxkit. To achieve our goals of a secure, lean and portable OS,we built it from containers, for containers.  Security is a top-level objective and aligns with NIST stating, in their Continue reading…

Modernizing Java Apps with Docker

[This post was written by Sophia Parafina and Arun Gupta.] Modernizing Traditional Applications or MTA was one of the themes at DockerCon EU 2017. Traditional applications are typically built a number of  years ago but are critical to business operations. The developer and operational skill set to maintain the application may be hard to find. The code base can be difficult to maintain, if it is available at all. The team that wrote the original app may not even be around. The applications go into maintenance mode, which may mean they are patched regularly for vulnerabilities. Any revisions to the code can take significant number of hours to test and deploy, so updates are infrequent. It can also hold back infrastructure improvements as dependency management becomes a huge pain point. Any modern application needs a faster delivery time that can Continue reading…

Docker Leads 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 Continue reading…

Docker at Nutanix .NEXT Conference – Visit us at Booth #S11

Today marks the start of Nutanix .NEXT Conference in Washington, D.C., the annual conference for Nutanix customers and partners. One of the major themes of the conference is hybrid cloud, and Docker will be there to demonstrate how Docker Enterprise Edition delivers application portability across different infrastructure platforms through a complete enterprise-ready Container as a Service (CaaS) solution for IT. Docker and Nutanix will also be highlighting the Nutanix Docker Volume Plug-in (DVP), a Docker Certified Plugin available in the Docker Store. This plugin connects Docker containers to enterprise-grade persistent storage from Nutanix even as the container is powered on, powered off, or moved to a new host. As part of the certification process, Docker and Nutanix validate that the plugin is built with Docker recommended best practices and passes an additional suite of API compliance testing and vulnerability scanning. Continue reading…

Your Docker Agenda for Cisco Live 2017 – Booth #2900B

The Docker team is headed to Las Vegas next week for Cisco Live – visit our booth #2900B to learn more about Docker Enterprise Edition and our integration with Cisco UCS, Contiv and the Cisco Validated Designs available for modern container deployments at enterprise scale. Docker and Cisco formed a partnership earlier this year to bring validated and supported solutions for the enterprise. Whether you are containerizing legacy apps to accelerate datacenter refresh or planning your first microservices application, Docker and Cisco deliver integrated solutions that have been tested to perform at scale – up to thousands of containers. Add these Docker sessions to your schedule: Tuesday, Jun 27, 1:20 pm – 1:30pm | Cloud Education Zone  Title: Maximize ROI by Modernizing Traditional Apps with Docker and Cisco  Tuesday, Jun 27, 3:30 pm – 4:30 pm | Level 3, South Continue reading…

Docker Enterprise Edition Now on G-Cloud 9 Framework

  Docker Enterprise Edition (EE) has been accepted to G-Cloud 9, further exemplifying Docker’s commitment to delivering tools for application modernization and innovation across the UK public sector. G-Cloud 9 is the UK government’s latest framework that is designed to simplify and accelerate adoption of cloud-based services within the public sector. The inclusion of Docker Enterprise Edition subscriptions, training and Professional Services Organization (PSO) within HM Government Crown Commercial Service’s (CCS) G-Cloud 9 Framework gives UK public sector organizations the opportunity to procure the de facto container solution through the online store known as the “Digital Marketplace” without needing to run a full tender, competition or lengthy procurement process. Docker’s meteoric rise within enterprise-class business has been built on its ability to be agnostic, agile and secure – whether for hybrid cloud migration, modernizing the application stack or adopting a DevOps methodology. Bringing application modernization to Continue reading…

Announcing the Docker Student Developer Kit & Campus Ambassador Program!

For quite some time now we have been receiving daily requests from students all over the world, asking for our help learning Docker, using Docker and teaching their peers how to use Docker. We love their enthusiasm, so we decided it was time to reach out to the student community and give them the helping hand they need! Understanding how to use Docker is now a must have skill for students. Here are 5 reasons why: Understanding how to use Docker is one of the most important skills to learn if you want to advance in a career in tech, according to Business Insider. You can just start coding instead of spending time setting up your environment. You can collaborate easily with your peers and enable seamless group work: Docker eliminates any ‘works on my machine’ issues. Docker allows you Continue reading…
