2. How to create resource objects through YAML resource manifest files?

2.1 Namespace

apiVersion: v1
kind: Namespace
metadata:
  name: test

2.2 Pod

apiVersion: v1
kind: Pod
metadata:
  name: pod1
spec:
  containers:
  - name: k8sonline1
    image: nginx:latest
    imagePullPolicy: IfNotPresent

2.3 Deployment

apiVersion: apps/v1
kind: Deployment
metadata:
  name: deploy-nginx			
spec:				
  replicas: 1				
  selector:
    matchLabels:
      app: nginx			
  template:					  
    metadata:
      labels:

        image: nginx:1.15-alpine
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 80

2.4 Service

apiVersion: v1
kind: Service
metadata:
  name: deploy-nginx-svc
spec:
  type: ClusterIP
  ports:
  - protocol: TCP
    port: 80
    targetPort: 80
  selector:
    app: nginx
