Yaml in kubernetes

A kubernetes yaml file will always contain top 4 level fields (required field)

apiVersion:
kind:
metadata:

spec:

______________________________________________________________________

kinds : Pod (can be Pod , service , ReplicaSet , Deployment)
metadata:
    name: myapp-pod
    labels:
      app: myapp

metadata values are in the form of the dictionary
metadata can only have name and labels
however, labels can have as many properties as u wish

spec  is a dictionary
spec:
   containers: (this is an list or an array bcz pods can have multiple containers within them)
       - name : nginx-container (the - indicates that this is the first item in the list)
          image : nginx


create the pod using the command
kubectl create -f pod-definition.yml

once you create the pod,, to see it use the command
kubectl get pods

to get the detailed description about the pods use:
kubectl describe pod {name from get pods command}


eg.
apiVersion: v1

kind: Pod

metadata:
  name: myapp-pod
  labels:
    name: myapp
    type: pod

spec:
  containers:
    - name: nginx-image
      image: nginx
