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

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

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.

In the fall of 2020, VMware sent a curt email to all subscribers on its PWS — Pivotal Web Services — platform informing them that come January 15th, 2021, they would need to move all of their applications to … elsewhere. Understandably, this caused a great deal of confusion among the PWS customer base. It’s

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

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,

Stark & Wayne announced the launch of SHIELD Cloud, a data protection system offered for Linode. SHIELD Cloud is a systems-based data protection system that is hyper-aware of what it is protecting, and can perform certain domain-specific tasks before and after the snapshot of data is taken. SHIELD Cloud understands your data systems at a

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

Everything is going great so far. That’s awesome! But then, you try to deploy a helm chart for that fancy new app you’ve
