The Pod we’ll deploy is defined in a YAML file called pod.yml.

The file can have any name, but its contents follow strict YAML rules. YAML is a popular language for configuration files and is very strict about indentation.

apiVersion: v1
kind: Pod
metadata:
  name: first-pod
  labels:
    project: qsk-book
spec:
  containers:
    - name: web
      image: nigelpoulton/qsk-book:1.0
