YAML Structure in Kubernetes
Kubernetes uses YAML files to describe what you want the cluster to create.
Instead of writing code, you declare the desired state.

Basic structure
Every Kubernetes YAML usually has 4 main parts:
- apiVersion
- kind
- metadata
- spec
—
Simple example
apiVersion: v1
kind: Pod
metadata: name: my-pod
spec: containers: - name: nginx image: nginx

Key idea
YAML is NOT procedural. It is declarative:
- You say what you want
- Kubernetes figures out how to do it
