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 Continue reading…

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 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: 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, 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 Continue reading…

Announcing Docker 17.06 Community Edition (CE)

Today we released Docker CE 17.06  with new features, improvements, and bug fixes. Docker CE 17.06 is the first Docker version built entirely on the Moby Project, which we announced in April at DockerCon. You can see the complete list of changes in the changelog, but let’s take a look at some of the new features. We also created a video version of this post here: Multi-stage builds The biggest feature in 17.06 CE is that multi-stage builds, announced in April at DockerCon, have come to the stable release. Multi-stage builds allow you to build cleaner, smaller Docker images using a single Dockerfile. Multi-stage builds work by building intermediate images that produce an output. That way you can compile code in an intermediate image and use only the output in the final image. So for instance, Java developers commonly use Apache Maven to compile 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…
