Ported second generation Chicago Gang History website from Pantheon to a multi-node K3s cluster on Digital Ocean, saving Zach over $400 a month in fees after an
unexpected price hike from his hosting provider.
How to install Wordpress with Bravada theme for local development in 8 steps.

Last week Pantheon dealt the final blow to the website I drove from 100 visitors up to 80,000 per month. By the time I heard the death knell we had a 10-day advance notice the price of hosting was increasing 1025% to $450/month.
I quickly spun up a Plesk instance on
Digital Ocean and installed WordPress on a $10/month VPS but realized Plesk was too bloated for our needs and probably not going to cut the mustard in the scale department should traffic decide to climb.
After initially attempting to deploy Wordpress using the Helm chart by Bitnami via the App Marketplace in Rancher 2.5 I found the chart difficult to use, kept looking and eventually found a
an alternative chart on a self-hosted VCS.
Like the Bitnami chart the independent chart includes optional database set-up. Unlike the Bitnami chart, however, the self-hosted chart also includes a Redis object cache, OpenID Connect authentication. It also builds a hardened WordPress Pod using WP CLI from scratch with Ansible inside an
Init Container. And in this tutorial I’m going to show you how you install it on macOS with K3D.
In this post we’re going to take a quick look at how to run
Rancher in a Kubernetes cluster locally on macOS for development and testing purposes.
There are several different ways to run Kubernetes for local development. In this guide I’m going to focus on just one way:
K3D is a lightweight wrapper to run Rancher Labs'
K3s in Docker. K3s is a certified Kubernetes distribution for edge and IoT applications with a small resource footprint and ARMv7 support. Like
KiND, K3D uses a container runtime as opposed to a virtual machine — saving precious resources. Unlike KiND, K3D supports the ARM architecture and requires about 16x less RAM.
When you’re finished you’ll have a functional K3s Kubernetes cluster running on your Mac with Rancher UI for cluster management. This guide assumes you’ve never run Kubernetes before and, therefore, also serves as a practical starting point, though I won’t be going into detail about the
nuts and bolts of Kubernetes.
