====== 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
