Lesson 4: Deployments

2 min

Understand what a Deployment is
Create Deployments
Scale an application
Ship updates with no downtime

4.1 The problem with standalone Pods

What goes wrong

In the previous lesson, we created Pods directly. But:

If a Pod crashes → it does not restart
If you want 5 copies → you have to create 5 files
For an update → you have to delete everything and recreate it

That is not manageable in production!

The solution: Deployments

A Deployment is a resource that:

Manages several identical Pods (replicas)
Restarts them automatically if they crash
Allows progressive updates
Keeps the version history
