Learn kubectl apply

kubectl Commands

kubectl apply -f reconciles the cluster to a manifest declaratively; diff -f previews the change and delete -f removes it.

Declarative management means you describe the desired state in YAML and let kubectl apply make it so.

apply -f creates resources that do not exist and updates those that do, tracking changes you made.

diff -f previews the exact changes, and delete -f tears down precisely what the file declares.

apply -f reconciles to the manifest.

diff -f previews the change.

delete -f removes the file's resources.

kubectl apply -f deploy.yaml
kubectl diff -f deploy.yaml
kubectl delete -f deploy.yaml

Connect each part of the code to the concept before you type.

apply -f reconciles the cluster to match the manifest, creating or updating as needed.

kubectl apply -f deploy.yaml

diff -f shows what apply would change before you run it.

kubectl diff -f deploy.yaml

delete -f removes exactly the resources defined in the file.

kubectl delete -f deploy.yaml

Read the concept map and follow the code breakdown.

Type the implementation, repair mistakes and work through every recall exercise.

Use the final check without hints; revisit weak concepts in short practice sessions.
