Kubernetes

As part of our ongoing Sustainability and Maintenance efforts, we are upgrading our Kubernetes clusters to version 1.32. Much like a major Django upgrade, this process requires us to update other key components to ensure they remain compatible. One of these is the ingress-nginx controller, which manages external access to the cluster.

At Caktus, we use Helm charts to simplify our deployment process for Django projects. Helm is a package manager for Kubernetes, and using Helm charts allows us to automate the process of writing Kubernetes configuration files for our Django applications. We use it together with GitHub Actions and Ansible to streamline our deployment processes.

Amazon Elastic Kubernetes Service (Amazon EKS) released support for operational cluster add-on software, or Amazon EKS add-ons, around Kubernetes version 1.19 in May 2021. These include:

For the Review, Appraisal, and Triage of Mail (RATOM) project, funded by the Andrew W. Mellon Foundation, we were tasked with deploying to a Microsoft Azure environment. More details about the project are in our first blog post in this Learn With Us blog series. Caktus has experience with Amazon Web Services (AWS) and Google Cloud, but we hadn't had the opportunity to use Azure yet, so we looked forward to the opportunity to use that environment and document our experience. The entire deployment process is available on GitHub as a reference under the StateArchivesOfNorthCarolina/ratom-deploy repository.
