Implementing Non-Trivial Containerized Systems – Part 4: Adding a Web Interface

This is the fourth 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’ve got a working system, our own rebuildable images, and a portable Docker Compose

A Decade With Cloud Foundry

Buddhism has its Four Noble Truths. Plato had his Ideals. We’ve spent close to a decade running applications on top of the Cloud Foundry platform-as-a-service (PaaS), and here’s a few universal truths about application development and deployment that we hope you’ll bring to your next Kubernetes project. Start Strong. One of the great joys of

Implementing Non-Trivial Containerized Systems – Part 3: Deploying Containers Together

This is the third 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 take the notes we took during the last part (you did

Implementing Non-Trivial Containerized Systems – Part 2: Containerizing with Docker

This is the second 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 take the architecture we cooked up in the last part, and

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. No

cf-protect — SHIELD for Your Cloud Foundry Applications

As far as enabling technologies go, CF is pretty. Write some code, wire up some marketplace services, and then simply cf push your way to a running, scalable web application. I daresay it’s effortless. A sheer joy to use. It’s definitely lead to more applications and more instance replicas. Can you imagine even attempting microservices

Deploying CF Applications via GitHub Actions

Over the past decade or so I’ve developed a strong allergy to typing commands after having already typed other commands. I’d rather have computers react to me, and do what needs to be done whenever they see telltale signs that I want to see change in the internet. I call this “declarative automation.” For years,

Deploying Kubernetes via Gluon

Gluon is an exciting new Kubernetes controller that brings the full power of BOSH to a Kubernetes world. With three simple and straightforward CRDs, Gluon lets Kubernetes operators deploy VMs via BOSH, upload stemcells, and manage cloud and runtime configs, all from the comfort of kubectl. Today we’re going to do the improbable: starting with
