Implementing Non-Trivial Containerized Systems – Part 1: Picking Components

So, you want to start a radio station, eh? This is the first part of a multi-part series on designing and building non-trivial containerized solutions. We’re making a radio station using off-the-shelf components and some home-spun software, all on top of Docker, Docker Compose, and eventually, Kubernetes. In this part, we’re going to explore how

Implementing Non-Trivial Containerized Systems

Your average blog post / tutorial / video about containerizing software goes a little something like this: Trouble is, all that “simple Docker stuff” is where things can (and often do!) go horribly horribly wrong, and there is precious little material available out there on the Internet for helping you through those precarious bits.

Running cf-for-k8s on Minikube

Photo by Henrique Félix on Unsplash The cf-for-k8s project is an interesting twist to running Cloud Foundry on Kubernetes using more “Kubernetes”-native projects like Istio, Eirini, and Fluentd. If you are interested in giving cf-for-k8s a spin on your own laptop the instructions below will create a Kubernetes (Minikube) and install cf-for-k8s. These instructions borrow

Tweed is an on-demand service broker that targets both Kubernetes and BOSH for deploying mission-critical data services, in both shared configurations (running as containers on a Kubernetes cluster) and dedicated configurations (running as virtual machines in a cloud IaaS of your choice). How
