Up and running!

It took me a little while, but I finally got this thing up and running! Hello, world!?

I thought building a site was going to be easy. Sure, it's simple to build something to host static pages built on top of WordPress in PHP, but that's so mid-2000's LAMP anyone?!). I was up for more of a challenge when I started building this, so I picked some building blocks that satisfied the following:


A site (usually) needs a webserver backing it. Something to serve up the content to the clients that connect to it. While the initial goal is to serve up static content, I wanted to use somthing that was going to be a little more versatile and flexible if I wanted to experiment with something fancier in the future.

I use Java at work, so I'm confident working in the JVM ecosystem. The tooling and support is pretty extensive and mature, and it's easy to StackOverflow your way out of a problem if / when you get stuck. I've been learning Scala on the side for a while as an excuse to get my head out of the "everything is a noun" approach to software development in Java this if you haven't already), so wanted to get my teeth sunk into a decent project.

Googling "Scala" and "web development" will probably lead you to the Play framework. It's pretty easy to use if you're like me and have used another MVC framework like Rails. Given that you're writing Scala, it's all statically typed, incuding the HTML templates. Less of those gross runtime errors.

I've recently started doing some Golang at work, so maybe if I get sick of Play I might have a play around with porting some of this to Go. Who says I can't be irresponsible and do a re-write when I want to?!

I've slapped nginx in front of the backends as a reverse proxy. It's 2017 and it's better than Apache. Sure, I'm not serving up thousands of requests a second, but we use it at work so I know a thing or two about how to configure it. It can cache things nicely, and terminate SSL (when I get around to it!).


While HTML was probably the "language" that got me into programming at an early age, building small web pages that I could run on the computer I'd built from parts I'd picked up at garage sales in the small country town in which I grew up (represent!), it's never really been a strong point. Javascript is gross. *#sorrynotsorry*.

Every week there's a new framework on the Orange Website that all the cool kids are using. It's exhausting to keep up with. So I'm sticking to my roots here and the content for the site is nothing fancy. It's just static HTML with some CSS to make things look pretty.

Given the backend is Play / Scala, maybe I'll get around to checking out something like scala.js ... maybe.


I've always been a bit of a Google fan-boy, and have used GCP for a while now, both at work and for various side projects, so this was a pretty easy choice. That said, you could probably throw this site up on AWS or Digial Ocean pretty easily.

I like how easy and fast it is to iterate on GCP relative to the competition. I'm slowly coming around to the idea of "immutable infrastructure", where you can treat your VMs as immutable, expendable and ephemeral. If something stops working, spin up a replacement and keep moving. GCE is pretty good for this, and you can have an instance up and SSH-able in less than a minute.


Ask any hipster what they're using these days for deploying their artisanal, hand-rolled, functional, stateless, reactive microservices and they'll probably drop the C-word. "Containers" are pretty much synonymous with Docker these days (although obviously there are others - see LXC ad and Rkt for two notable examples). Using Docker containers unlocks cool frameworks like Kubernetes for service discovery and deployment. We've got a pretty similar framework at Square, p2 that is heavily inspired by Kubernetes, so the concepts and abstractions are familiar to me, which is a bonus.

Google has a hosted Kubernetes service called Google Container Engine (GKE) which abstracts away the pain of adding and removing VMs from your cluster and getting them talking to one another.

Kubernetes is another tool I can add to the tool-belt. A bunch of companies are already using it (probably in production, but maybe they'd be reluctant to admit that openly). The open source community is huge, and the project is constantly evolving. No doubt things will look different in a month's time. There will be different abstractions to use. Hey - if I ever end up with a database backing this thing (god forbid), I'll be keen to checkout how Kubernetes deals with StatefulSets.

So ... here we are. We've got the broad strokes of a website engraved in a single HTML document, checked into a Github repo, building and deploying on GCP. I know it works coz you're reading it, and I know a thing or two from a past life on how to scrape and analyze web logs to tell what kind of browser you're reading it from and where you are! ... or at least where the IP of your Tor exit node appears to be.

Stay tuned ... my creative juices have to refill. Writing is hard.
