cluster-proportional-autoscaler

This container image watches over the number of schedulable nodes and cores of the cluster and resizes the number of replicas for the required resource. This functionality may be desirable for applications that need to be autoscaled with the size of the cluster, such as DNS and other services that scale with the number of nodes/pods in the cluster.

Creating Terraflow, a CI/CD orchestrator to scale Terraform

Managing Terraform and Terragrunt at scale can be challenging! My team was spending much time identifying affected stacks and dealing with plan and apply processes, leading to increased drift risks. Existing solutions like Atlantis, Digger, and Spacelift didn’t fully meet our needs, so we decided to build our own! This article details why and how we developed Terraflow to have stack detection, manage dependencies, and simplify our deployment workflows.

Some refer to tools like Terraflow as TACOS, which stands for Terraform Automation and Collaboration Software. TACOS frameworks are designed specifically to tackle the challenges of operating IaC at scale by streamlining automation, collaboration, and control across infrastructure deployments.

The Containerization Tech Stack

The lifecycle of containers — from their high-level orchestration through to their low-level execution in the kernel — requires the interaction of many components, each abstracting away different levels of functionality. In this article we’ll explore the different technologies in this hierarchy which make containers possible. We’ll also touch on virtualization and sandboxing technologies.

Kubernetes Storage Performance Comparison Rook Ceph and Piraeus Datastore (LINSTOR)

Understanding Kubernetes storage is crucial for deployments that rely on persistent volumes within K8s. In this article, we’ll explore various software options for K8s storage based on online research. Additionally, we’ll delve into two specific choices that offer replicated block storage: Piraeus Datastore (LINSTOR) and Rook Ceph.
