Introduction Wordpress development agencies often excel at crafting beautiful, functional websites but may lack the infrastructure skills to offer robust hosting solutions to their clients. Some agencies even have the in-house skill to run and operate infrastructure, but they streer their strategy towards VPS-based/reseller solutions, eating up a big chunk of their profits. I recently started pondering with how this could be fixed by having something central (so that we didn’t have to deal with a bunch of different resources, for efficiency reasons) and still maintain a good service level.

Intro Consider this article a memouir of my endeavours with provisioning an EKS cluster with Terraform instead of kubectl. Most of the articles and tutorials I could find online focus on simple use-cases and everything looks bright. Also, I noticed that a specific Terraform module is widely used by the community for spinning up a new EKS cluster. This article focuses on what can go wrong and takes an angle on how that can be solved. [Read More]

After many years of using DroneCI, Gitlab or Travis for most of my projects, I thought to give Github Actions (GA) a try. My scope was to deploy a side-project I have on AWS EKS, but make it as automated as possible in every aspect.
