The YAML syntax in your deployment manifest is incorrect. YAML is very sensitive to indentation and requires specific formatting to correctly express the nested structure of the configuration.

apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-deployment
spec:
  replicas: 3
  selector:
    matchLabels:
      app: my-app
  template:
    metadata:
      labels:
        app: my-app
    spec:
      containers:
        - name: my-nginx
          image: nginx
          ports:
            - containerPort: 8080

Apply the same using kubectl apply -f <filename.yaml>
