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.

Every Kubernetes YAML usually has 4 main parts:

• apiVersion
• kind
• metadata
• spec

—

apiVersion: v1

kind: Pod

metadata: name: my-pod

spec: containers: - name: nginx image: nginx

YAML is NOT procedural. It is declarative:

• You say what you want
• Kubernetes figures out how to do it
