FRR-k8s as a BGP backend for MetalLB

The FRR-k8s API provides important Border Gateway Protocol (BGP) features required by the MetalLB load balancer with the ability to selectively accept routes and to inject raw FRR configuration options. It's built on FRRouting (FRR), a free and open source internet routing protocol suite for Linux and Unix platforms that implements Border Gateway Protocol (BGP) and Bidirectional Forwarding Detection (BFD).

Pod Disruption In Kubernetes

In the world of Kubernetes, ensuring high availability of application during maintenance and upgrades can be a frustrating this has happened to me most times. As you scale and manage containerized applications, minimizing downtime and maintaining service continuity becomes a huge challenge especially when a simple human error can cause service disruption. This is where the concept of Pod Disruption Budgets (PDBs) comes into play, today we will dive deep into the fundamentals of Pod Disruption Budget explore how to implement them in your Kubernetes clusters.

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.
