Seeing Inside Amazon EKS with OpenTelemetry 🔍

Sat, 20 Jun 2026 07:45:10 +0530

Why This Setup?

Before getting into the architecture, a few quick notes. Telemetry goes to both New Relic and Honeycomb to test OpenTelemetry’s backend-independence promise and compare the two. New Relic wins on day-to-day usability — dashboards, APM, and alerts work intuitively. Honeycomb takes more getting used to, but its MCP server is where it genuinely shines: connected to Claude, you can ask plain-English questions against live telemetry — no NRQL or PromQL required. That’s the part worth jumping to 👇 first if you’re short on time.

Kubernetes StatefulSets Explained - When and Why to Use Them

Tue, 07 Apr 2026 10:30:10 +0530

What is StatefulSet

StatefulSets are used to manage stateful applications, such as databases or other applications that keep track of their state. By using StatefulSets, a set of pods can be deployed and scaled, ensuring that they are ordered and unique.

Kubernetes Health Checks with Probes

Mon, 11 Nov 2024 19:26:10 +0530

What are probes

The word “probe” in a general sense means a detailed investigation or inspection to gather information or check the condition of something. It’s often used in contexts where you’re trying to assess the status or health of something.

Monitoring Kubernetes Cluster with Prometheus and Grafana

Mon, 10 Jun 2024 19:26:10 +0530

Introduction:

Keeping an eye on your Kubernetes cluster can feel like a daunting task, but with the right tools, it doesn’t have to be. Prometheus and Grafana – two fantastic open-source tools that make monitoring and visualizing your cluster easy.

Kubernetes Security — Role Based Access Control (RBAC)

Mon, 20 May 2024 19:26:10 +0530

Introduction

Role-Based Access Control (RBAC) is a method used in computer security to manage access to resources within a system.

RBAC in k8s is based on the principle. There are various terminologies such as users, service account, role, role binding and etc.

Helm — Your Compass in the Kubernetes Universe

Wed, 01 May 2024 19:26:10 +0530

What is Helm:

Helm, the package manager for k8s similar to package manager for linux such as apt (Debian/Ubuntu based) yum/dnf (Red Hat or Fedora family of linux) , which helps us with packaging and deploying application.

Ingress in K8s - Name based Routing with TLS

Sun, 07 Apr 2024 19:26:10 +0530

Preface:

In the previous article we saw how to use nginx ingress for routing. Today we will experiment with adding domain to our app and will also use TLS cert for the domain.

Getting Started with Ingress In Kubernetes

Mon, 01 Apr 2024 19:26:10 +0530

Introduction:

In Kubernetes, “Ingress” is an API object that manages external access to services within a cluster.

It acts as a layer above the services, providing routing rules and load balancing for HTTP and HTTPS traffic. Essentially, it allows you to define how external traffic should be directed to services based on rules you set up, such as hostnames, paths, or other HTTP headers.

ArgoCD GitOps for Kubernetes - From Code to Cluster

Sat, 10 Feb 2024 19:26:10 +0530

What is GitOps:

Gitops is a practice in devops where managing applications using git is considered as a single source of truth. This is generally used in the Kubernetes world.

This means we define our application for kubernetes using declarative objects in our git repo and no manul modifications are allowed to do in the k8s cluster.

Calico and Kubernetes: A Perfect Pair for Robust Network Policy

Mon, 22 Jan 2024 19:26:10 +0530

Before we begin:

Make sure to have calico as the network provider for the k8s cluster.

Introduction:

By default k8s allows all pods to communicate with each other in a cluster across namespaces.

Delving into the World of Deployments in Kubernetes

Sat, 24 Jun 2023 19:26:10 +0530

In the previous article, we saw ReplicaSet, Services and touched base on deployment. In this article, we will explore deployments in more detail.

As we already created deployments using the cmd line, here we’ll use yaml. We’ll combine replicaset and service config with the deployment config.

Note: kctl is an shell alias for kubectl

 
 

 

 YAML
 

 
 
 
apiVersion: apps/v1
kind: Deployment
metadata:
 name: mywebapp
 annotations:
 kubernetes.io/change-cause: "initial deployment"
spec:
 replicas: 3
 selector:
 matchLabels:
 app: data
 template:
 metadata:
 labels:
 app: data
 spec:
 containers:
 - name: prodapp
 image: quay.io/gauravkumar9130/production:v1
apiVersion: apps/v1
kind: Deployment
metadata:
 name: mywebapp
 annotations:
 kubernetes.io/change-cause: "initial deployment"
spec:
 replicas: 3
 selector:
 matchLabels:
 app: data
 template:
 metadata:
 labels:
 app: data
 spec:
 containers:
 - name: prodapp
 image: quay.io/gauravkumar9130/production:v1

 
 

Apply the deployment and expose the service with the load balancer type. (using the cmd line, for now, will merge later).

Container Orchestration: Kubernetes 101

Thu, 22 Jun 2023 19:26:10 +0530

Introduction:

Kubernetes , also known as K8s, is an open-source platform to automate deployment, scaling, and management of containerized applications or containers.
