Quasars: Paving the way to Kubernetes

There’s been some significant infrastructure changes under the hood of Quasars and I wanted to talk about them here.

What changed

In another blog post I had talked about how Quasars uses Blue/Green Deployments, but as of today, that is no longer the case. In reality, very little has changed. Instead of having two web servers being toggled between with a floating IP, these two web servers fulfill requests behind a load balancer.

The rationale

Quasars is a hobby project. As such, it serves an important role of being a conduit in which I can learn new technologies. Kubernetes is one of these technologies. The use of a load balancer prepares Quasars to adopt Kubernetes in a couple ways:

  • Kubernetes will define a load balancer and a few nodes. In some ways this is miming one possible cluster configuration.

So, is Kubernetes overkill for a web application that receives < 10 requests per minute? Definitely, but that’s not the point. 🙂

Next steps

The next thing I’ll be working on is getting a containerized build going and publishing that to Docker Hub through CI/CD. Once that is in place I can start configuring a Kubernetes cluster and eventually do a cutover.
