Kubernetes Basics for DevOps Engineers

Introduction:
Kubernetes can feel overwhelming when you first hear terms like Pods, Services, and Deployments thrown around. In this first post of my Kubernetes series, I’ll break down the fundamentals — what Kubernetes actually solves, and the core building blocks you need to understand before going further.

What is Kubernetes?
Kubernetes is an open-source container orchestration tool, originally developed by Google. It helps manage containerized applications across different environments — physical machines, virtual machines, and cloud environments — which makes it a great fit for hybrid deployment setups.

Why Kubernetes? The Problem It Solves
To understand why Kubernetes exists, look at the trend that led to it:

Applications moved from monolith to microservices.
That shift drastically increased the number of containers teams had to manage.
Managing hundreds of containers by hand became unsustainable — teams needed a proper way to orchestrate them.

Key Features

High Availability — no downtime
Scalability — scale up or down based on load and performance needs
Disaster Recovery — backup and restore built into the ecosystem

Main Kubernetes Components

Pods: Abstraction over containers
Services: Stable networking & communication
Ingress: Routes external traffic into the cluster
ConfigMaps & Secrets: External configuration
Volumes : Data persistence
Deployments & StatefulSets: Replication (stateless vs. stateful)
DaemonSets: One Pod per node, auto-scaled with the cluster

Hey Dev Community! 👋

I’m Tejas, a DevOps Engineer from Bangalore, new to this platform. I work mostly with AWS, Kubernetes, Terraform, and Jenkins, and I’ll be sharing what I pick up along the way — CI/CD, Kubernetes in practice, IaC patterns, and the occasional “here’s what broke and how I fixed it.”

Still learning every day, but happy to share whatever I know — and even happier to learn from you all. Feel free to connect or drop a comment! 🚀
