The YAML format is very simple, with few syntax rules; therefore, it is easy to read and write, even for users. To know more about YAML, you can refer to the following website link: http://www.yaml.org/spec/1.2/spec.html. The following example uses the YAML format to set up the nginx Pod:

$ cat nginx-pod.yaml
apiVersion: v1
kind: Pod
metadata:
  name: my-nginx
  labels:
    env: dev
spec:
  containers:
  - name: my-nginx
    image: nginx
    ports:
    - containerPort: 80
