In this session of the Kubernetes module, we go beyond Pods and dive deep into replication in Kubernetes. You’ll see how ReplicaSets and Deployments ensure your applications stay online, self-heal, and scale automatically.


What you’ll learn in this video:

Pods recap: smallest deployable unit in K8s

Creating Pods via CLI + YAML manifests

Multi-container Pods (sidecar/helper design patterns)

Pod lifecycle: restarts, failures, logs & debugging

🔥 ReplicaSets explained: why they matter for scaling & reliability

Defining replicas in YAML: scaling from 1 to many Pods

Self-healing: how ReplicaSets restart Pods automatically

Deployments built on top of ReplicaSets

Rolling updates & zero-downtime deployments in real-world apps

Hands-on kubectl commands to manage scaling & updates

Live demos and practice exercises to reinforce replication concepts

This day is all about high availability and scale in Kubernetes. Mastering ReplicaSets + Deployments is key to running production workloads smoothly.
