Kubernetes is Now Available In Docker Desktop Stable Channel

Back in January we made Kubernetes available in our Edge release channels for Docker Desktop on macOS and on Windows. Today we’re excited to announce that Kubernetes orchestration has graduated to the Stable release channels for Docker Desktop! Docker Desktop is the fastest and simplest way to get a Kubernetes cluster running on your desktop machine, while still giving you the freedom to choose Docker Swarm if you prefer. Docker Developer Advocate Elton Stoneman recently created a short video demonstrating Docker Desktop on both Windows and Mac. In the video, Elton demonstrates: Enabling Kubernetes and alternating between Kubernetes and Swarm Integrating Docker Desktop and containers in to your environment and workflow Deploying .NET, NodeJS, and Java apps with Docker Desktop, including deploying to Kubernetes with a Compose file Click image below to watch video: Docker Desktop is simple to install Continue reading…

Introducing an Easier Way To Design Applications in Docker Desktop

In today’s DockerCon keynote we previewed an upcoming Docker Desktop feature that will make it easier than ever to design your own container-based applications. For a certain set of developers, the current iteration of Docker Desktop has everything one might need to containerize an applications, but it does require an understanding of the Dockerfile and Compose file specifications in order to get started and the Docker CLI to build and run your applications. But we’ve been thinking about ways to bring this capability to ALL developers. We want to make it easier to get started with containerization, and we want to make it even easier to share and collaborate and integrate container-based development in to more developers’ toolsets. This new guided workflow feature is a preview of what we’re working on and we wanted to share more details on the Continue reading…

Docker for Desktop is Certified Kubernetes

“You are now Certified Kubernetes.” With this comment, Docker for Windows and Docker for Mac passed the Kubernetes conformance tests. Kubernetes has been available in Docker for Mac and Docker for Windows since January, having first being announced at DockerCon EU last year. But why is this important to the many of you who are using Docker for Windows and Docker for Mac? Kubernetes is designed to be a platform that others can build upon. As with any similar project, the risk is that different distributions vary enough that applications aren’t really portable. The Kubernetes project has always been aware of that risk – and this led directly to forming the Conformance Working Group. The group owns a test suite that anyone distributing Kubernetes can run, and submit the results for to attain official certification. This test suite checks that Kubernetes behaves Continue reading…

Docker Compose and Kubernetes with Docker for Desktop

If you’re running an edge version of Docker on your desktop (Docker for Mac or Docker for Windows Desktop), you can now stand up a single-node Kubernetes cluster with the click of a button. While I’m not a developer, I think this is great news for the millions of developers who have already been using Docker on their Macbook or Windows laptop because they now have a fully compliant Kubernetes cluster at their fingertips without installing any other tools. Developers using Docker to build containerized applications often build Docker Compose files to deploy them. With the integration of Kubernetes into the Docker product line, some developers may want to leverage their existing Compose files but deploy these applications in Kubernetes. With Docker on the desktop (as well as Docker Enterprise Edition) you can use Docker compose to directly deploy an application onto a Kubernetes Continue reading…

Beta Docker for Mac and Windows with Kubernetes

Today, as part of our effort to bring Kubernetes support to the Docker platform, we’re excited to announce that we will also add optional Kubernetes to Docker Community Edition for Mac and Windows. We’re demoing previews at DockerCon (stop by the Docker booth!) and will have a beta program ready at the end of 2017. Sign up to be notified when the beta is ready. With Kubernetes support in Docker CE for Mac and Windows, Docker Inc. can provide customers an end-to-end suite of container-management software and services that span from developer workstations, through test and CI/CD through to production on-prem or in the cloud. Docker for Mac and Windows are the most popular way to configure a Docker dev environment and are used everyday by hundreds of thousands of developers to build, test and debug containerized apps. Docker for Mac Continue reading…

User-guided caching in Docker for Mac

[This post was written by Jeremy Yallop and David Sheets.] Recent Docker releases (17.04 CE Edge onwards) bring significant performance improvements to bind-mounted directories on macOS. (Docker users on the stable channel will see the improvements in the forthcoming 17.06 release.) Commands for bind-mounting directories have new options to selectively enable caching. Containers that perform large numbers of read operations in mounted directories are the main beneficiaries. Here’s an illustration of the improvements in a few tools and applications in common use among Docker for Mac users: go list is 2.5× faster; symfony is 2.7× faster, and rake is 3.5× faster, as illustrated by the following graphs: go list (2.5× speedup) go list ./… in the moby/moby repository symfony (2.7× speedup) curl of the main page of the Symfony demo app rake (3.5× speedup) rake -T in @hirowatari’s benchmark For more details about how Continue reading…

The 10 Most Common Questions IT Admins ask About Docker

Over the past few months we have attended a string of industry tradeshow events, helping to teach the world about Docker for enterprise. We were at HPE Discover, DockerCon, RedHat Summit and Cisco Live all within the past 6weeks! I had the pleasure of helping to represent Docker at each events and spoke with attendees. Some folks worked in IT ops, while others worked in development. I also spoke with a lot of folks working as IT admins within their company’s infrastructure team, and over time, I began to notice some trends when it came to the types of questions they asked. This got me thinking. Why not put together a list of the most common questions from IT administrators? I mean there’s a good chance there are other IT infrastructure folks out there who have the very same questions, Continue reading…
