Kubernetes resources are described by manifests written in YAML. Every object in Kubernetes has a kind, apiVersion, and metadata. Most objects also have a spec.

# aren't backwards compatible, they are released as a new version.
apiVersion: apps/v1
# Every Kubernetes object has a kind which declares the type of the resource.
kind: Deployment
metadata:

# namespace for its kind.
