Understanding Kubernetes Deployments

Welcome to the world of Kubernetes Deployments! After learning about Pods, you might wonder how to manage many identical Pods reliably.

Deployments are a powerful Kubernetes resource that helps you declare and manage the desired state of your applications.

Imagine running a web server. You need multiple copies (replicas) for high availability and to handle traffic. If one crashes, you need another to take its place.

Deployments automate these tasks:

• Self-Healing: Replaces failed Pods automatically.
• Scaling: Easily adjust the number of Pod replicas.
• Updates: Perform rolling updates without downtime.
• Rollbacks: Revert to previous versions if something goes wrong.
