Load Testing Caddy Web Server on a GCP F1-Micro Instance Using K6 (k6.io)

March 24, 2020

TL;DR: I used the K6 load testing framework to benchmark the Compute Engine f1-micro and Caddy web server hosting this site. With Cloudflare caching turned off, the server was able to serve an onslaught of 800 virtual users continuously reloading the page (while maintaining a median request duration of <400ms), but started dropping requests when increasing the load further.

This is fine.

TL;DR: I set up Minikube on an old (2012) MacBook Air and configured it to be able to connect from outside my home network so I would have an always-on Kubernetes cluster at home to experiment with.

Managed Kubernetes Price Comparison (2020)

March 5, 2020

TL;DR: Azure and Digital Ocean don’t charge for the compute resources used for the control plane, making AKS and DO the cheapest for running many, smaller clusters. For running fewer, larger clusters GKE is the most affordable option. Also, running on spot/preemptible/low-priority nodes or long-term committed nodes makes a massive impact across all of the platforms.

CI/CD for this site (Hugo + Cloud Build)

Alternate title: Just use Netlify.

TL;DR: Deploy a Hugo site to GCP for free in less time than it will take you to read this article (Github Repo with all referenced commands)

EDIT: In October 2020 I updated the hosting of this site to use GCS + Cloudflare](https://devopsdirective.com/posts/2020/10/gcs-cloudflare-hosting/).
