From Fortran on the Desktop to Kubernetes in the Cloud: A Windows Migration Story

May 28, 20200 likes378 views

Elton Stoneman, Docker Captain + Container Consultant and Trainer How do you provide a SaaS offering when your product is a 10-year old Fortran app, currently built to run on Windows 10? With Docker and Kubernetes of course - and you can do it in a week (... to prototype level at least). In this session I'll walk through the processes and practicalities of taking an older Windows app, making it run in containers with Kubernetes, and then building a simple API wrapper to host the whole stack as a cloud-based SaaS product. There's a lot of technology here from a real world case study, and I'll focus on: - running Windows apps in Docker containers - building a .NET Core API which can run in Linux or Windows containers - running the stack in Kubernetes with Docker Desktop locally and AKS in the cloud - configuring AKS workloads in Azure to burst out to Azure Container Instances And there's a core theme to this session: Docker and Kubernetes are complex technologies, but they're the key to modern development. If you invest time learning them, they make projects like this simple, portable, fast and fun.

How to build your containerization strategyDocker, Inc.

The Docker Enterprise Edition platform helps customers deploy and manage applications faster and it secures the application pipeline at a lower cost than traditional application delivery models. But it takes more than just great technology to achieve the desired results. The organization and culture of your enterprise directly impacts what you transform, how it’s done, and who does it. Success requires a strategy for how you will govern the Docker EE container platform, how to assess your application estate, what your delivery pipeline will look like, and how to ensure developers, operators, security teams and others play nicely together. In this talk I will cover topics such as different types of workloads (legacy, microservices, FaaS, big data, ...), how your org chart can influence whether you deploy a CaaS (Containers as a Service) vs CLaaS (Clusters as a Service), how "shifting left" can determine if you can outsource, centralized vs distributed CI/CD and how containers play a role, transforming your pets into cattle, how giant whale balloons are used for onboarding, and a prescriptive and comprehensive methodology for successfully deploying Docker in your enterprise.

Docker for developers on mac and windowsDocker, Inc.

The whole Docker ecosystem exists today because of every single developer who found ways of using Docker to improve how they build software; whether streamlining production deployments, speeding up continuous integration systems or standing up an application on your laptop to hack on. In this talk we want to take a step back and look at where Docker sits today from the software developers point of view - and then jump ahead and talk about where it might go in the future. In this talk, we’ll discuss: * Making Docker an everyday part of the developing software on the desktop, with Docker for Windows and Docker for Mac * Docker Compose, and the future of describing applications as code * How Docker provides the best tools for developing applications destined to run on any Kubernetes cluster This session should be of interest to anyone who writes software; from people who want to hack on a few personal projects, to polyglot open source programmers and to professional developers working in tightly controlled environments. Everyone deserves a better developer experience.

Considerations for operating docker at scaleDocker, Inc.

"Scale" happens along 3 different aspects: (1) applications and their services scale up and down leading to (2) the infrastructure scaling up to meet the needs of the applications, and finally (3) sites scale across multiple locations, including movement to public cloud. In this session, we will talk about how Docker EE scales along all three of these dimensions to give you a consistent platform for running your applications: 1. At the application level: how do you manage application state & health along with resource and security constraints to scale containers up and down up in a controlled fashion? 2. The infrastructure level: as your application estate grows on the Docker EE platform you will need to scale across more nodes. How do automate the provisioning of these new nodes and how do you integrate the Docker EE platform layer with your existing infrastructure systems and tools. 3. Finally, we'll talk about distributed scale: how do you take what works for applications in one data center and spread it across multiple sites, in an integrated fashion so you can operate seamlessly?

Telepresence - Seamless Development Environments on KubernetesAdnan Abdulhussein

When developing API extensions or services that deeply integrate with Kubernetes, you may find yourself juggling kubeconfig contexts or iterating through a slow build-push-deploy cycle. Telepresence allows you to develop services locally as if they were running in your cluster. It does this by proxying pods to your local machine and gives your local services seamless access to service discovery and volumes. With Telepresence, you no longer have to maintain Docker Compose files for local orchestration, and you can take full advantage of Kubernetes features such as Ingress, Secrets/ConfigMaps, RBAC and more. In this demo-led session, we’ll take a look at how Telepresence works, the different ways you can use it and how it makes iteratively developing on Kubernetes a breeze.
