In Kubernetes, you can define the importance of Pods relative to others using PriorityClasses. This ensures critical services are scheduled and running even during resource constraints. Key Points: Scheduling Priority: When enabled, the scheduler prioritizes pending Pods based on their assigned PriorityClass. Higher priority Pods are scheduled before lower priority ones if their resource…

In Kubernetes, CPU limits define the maximum amount of CPU resources a pod is allowed to consume on a host machine. They play a crucial role in ensuring efficient resource utilization, preventing performance bottlenecks, and maintaining application stability within your cluster. Understanding CPU Requests and Limits Each node in a Kubernetes cluster is allocated memory (RAM) and compute power…

This article shows a nifty technique for live debugging Pods running in production using labels. The Scenario: Imagine you have a Deployment with three Pods, all labeled with app=tech. A Service routes traffic to these Pods based on this selector. Isolating a Pod: Use kubectl label pod <pod-name> app=debug --overwrite to change the specific Pod’s label to app=debug. Consequences: The…

In cloud-based deployments, Kubernetes clusters are often spread across multiple availability zones for redundancy and scalability. However, by default, Kubernetes services distribute traffic randomly between pods, which can lead to inefficiencies. Traffic might travel between zones unnecessarily, increasing latency and potentially incurring extra costs. In this post, let’s understand about…

Monitoring failed requests in your Azure Application Gateway is crucial for maintaining a healthy and responsive application. This blog post dives into the improved capabilities for identifying and analyzing these failures, empowering you to diagnose issues efficiently. Previously Limited Visibility: Limited Information: Previously, the Azure portal only displayed the total count of failed…

In Kubernetes, you have the power to tailor the commands that are executed within your containers. This flexibility is achieved through two key fields in Pod YAML files: command and args. Let’s dive into how they work: 1. command: Setting the Primary Command Think of command as the heart of the action, defining the main command to be run within a container. Specify it as an array of strings,…

Running out of resources in your Kubernetes cluster is a familiar foe for any K8s warrior. The dreaded “insufficient node resources” message leaves you facing a chaotic battleground of stalled pods, frustrated users, and a performance dip so steep it could rival a ski slope. But fear not, brave adventurer! This guide will equip you with the tools and strategies to navigate this perilous terrain…

We woke reasonably late following the feast and free flowing wine the night before. After gathering ourselves and our packs, we headed down to our homestay family’s small dining room for breakfast. Refreshingly, what was expected of her was the same thing that was expected of Lara Stone: to take a beautiful picture. We were making our way to the Rila Mountains, where we were visiting the Rila…
