We successfully scaled our Windows Docker containers running on one Docker host. But what if we change our focus and see our distributed application as a whole, running on multiple hosts using both Windows and Linux native containers?

In this case, a multi-node Docker Orchestration tool like Docker Swarm could be a marvelous option! Running Spring Boot Apps on Windows – Blog series Part 1: Part 2: Part 3: Part 4: Taming the Hybrid Swarm: Initializing a Mixed OS Docker Swarm Cluster running Windows & Linux Native Containers with Vagrant & Ansible Lifting our gaze to the application as a whole We really went far in terms of using native Docker Windows containers to run our apps inside. We built our own Windows Vagrant boxes with Packer, prepared them to run Docker smoothly and provisioned our Apps – both fully automated with Ansible. We also scaled our Windows Docker containers using Docker Compose and, not leaving our fully comprehensible setup and our willingness to have everything as code behind. But if you look into real world projects, there are no single nodes anymore – running Docker or not.

Applications today consist of a whole bunch of machines – and they naturally mix Linux and Windows. These projects need a solution to handle these distributed applications – ideally not doing everything with completely new tools.

But how is this possible? Best software to boot from usb for mac download. Why Docker Swarm? This post is all about the “new” Docker Swarm mode, requiring Docker 1.12.0 as a minimum.

But why did I choose this path? Today everything seems to point to: biggest media share, most google searches, most blog posts and so on. But there are a few things to consider before going with Kubernetes. The first point is simple: a consultant´s real world project experience. After having in-depth discussions about it, you maybe shifted your project team to Dockerize all the (legacy) applications and finally brought all these containers into production.

You should always remember: This is huge! And at least according to my experience not every team member already realized at that point what changes were applied to the team’s applications in detail, maybe also leaving some people unsure about “all this new stuff”. And now imagine you want to do the next step with Kubernetes. This means many of those “new” Docker concepts are again thrown over the pile – because Kubernetes brings in a whole bunch of new building blocks, leaving no stone unturned And every blog post about Kubernetes and every colleague I talk with has to admit at some point that the learning curve with Kubernetes is really steep.

Second point: Many people at conferences propagate the following precedence: They tell you about “Docker 101” with the simplest steps with Docker and then go straight ahead to Kubernetes as the “next logical step”. Well guys, there´s something in between! It should be common sense that learning is ideally done step by step.

On newer systems it's recommended to use the Docker for Mac or Docker for. Deployments and runtime management of multi-node applications that run as. Epson xp 830 scanner driver for mac. One can aggregate the logs of Docker containers running on the same host using. Based router for docker swarm mode with a fresh and more secure approach.

The next step after Docker 101 is Docker Compose, adding a new level of abstraction. Coming from Compose, it is easy to continue with Docker Swarm – because it is built right into every Docker engine and could be used with Compose as well.

It´s just called “Docker Stack” then. 🙂 And if people really do need more features than Swarm provides, then Kubernetes is for sure a good way to go! Last point: Right now, a hybrid OS Docker cluster doesn´t really make sense with the released versions of Kubernetes and Windows Server 2016. Yes, was released on Kubernetes 1.6 (alpha with 1.5 already). But if you dive a bit deeper – and that always involves reading through the Microsoft documentation until you reach the part “current restrictions/limitations” – you´ll find the nasty things.
