Deployments

Why Deployments

A Deployment owns a ReplicaSet, which owns pods. If a pod disappears, the controller creates a replacement.

Create a Deployment

Imperative example for practice:

kubectl create deployment hello --image=nginx:1.27
kubectl get deployments
kubectl get pods

See the ownership chain

Describe the Deployment and list ReplicaSets.

kubectl describe deployment hello
kubectl get rs

Delete the workload

Deleting the Deployment removes its pods.

kubectl delete deployment hello
