In our previous post, we talked about our recent client work building a Kubernetes-based system for hosting web applications. We’ve defined a general framework to support our development and production hosting workflows, and recognized this as a solid basis for an alternate backend to plug in to the existing Aegir5 front-end. Today we’ll take a look at the Drupal architecture underlying that front-end.
In Aegir5, the building blocks consist of Task and Operation entities.
Aegir5 and Kubernetes Lately we’ve been working with clients ranging from large Canadian government departments to small commercial SaaS companies, who have asked us to deploy CMS apps to Kubernetes (K8S) clusters running on Openstack. In spite of our continued feeling that most of the time Kubernetes Won’t Save You, we’ve found it to be surprisingly useful in certain contexts. In fact, we’ve started to think that K8S will prove an extremely valuable backend to plug in to our existing Aegir5 front-end and queue system.
Aegir5 development is happening! We (Consensus) have been making steady progress on it over the last few years and are looking to kick off a new burst of focused development. Here’s a summary of progress that has been made so far and how you can contribute.
First off, as you’re probably aware, Aegir5 is a complete re-write of Aegir. We are intending to build on all the great aspects of Aegir, while freeing ourselves from a codebase that is rooted in PHP 4.
For our cloud computing, we typically use an OpenStack provider because of its open-source nature: There’s no vendor lock-in, and the IaaS code is peer-reviewed unlike providers such as AWS, Azure, GCP, etc. (Shout out to Vexxhost for having great support!) As such, we’ve been using OpenStack’s Swift object storage service for storing Terraform’s state, which allows Terraform to track all of the resources it manages for automating infrastructure.
Recently, however, support for the Swift backend has been removed.
Terraform is an essential tool for automating cloud-computing infrastructure and storing it in code (IaC). While there are several ways to navigate between deployment environments (e.g. Dev, Staging & Prod), I’d like to talk about how this can be done with environment variables, and explain why it can’t be done more naturally with Terraform variables.
Introduction Last week our fully remote team gathered in person at a beautiful spot in Prince Edward County, Ontario, for our second annual company retreat. Our first iteration in 2021 was a resounding success, and we decided to do it again this year. In both cases, we took advantage of the high-bandwidth nature of being together in physical space to hold a variety of big picture conversations about our accomplishments, direction and goals.
Do you REALLY need a unicorn? Or (spoiler alert!!!) would a herd of horses with the necessary skills shared among them actually be a better solution to your problem?
