Tell about your experience with Kubernetes platform and its components.

In working with Kubernetes, I am familiar with the main components and their purposes:

• Pod — the smallest deployable unit, containing one or more containers.
• Deployment — manages the creation and updating of pods, providing declarative application updates.
• Service — an abstraction for accessing pods, providing load balancing and a stable IP.
• ConfigMap and Secret — for managing configuration and secret data.
• Namespace — resource isolation within the cluster.

I have used Kubernetes for deploying microservices, setting up auto-scaling, updating applications without downtime (rolling updates), as well as for monitoring and logging through integration with Prometheus and the ELK stack.

Example of a Deployment manifest:

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

This ensured stable application operation and simplified infrastructure management.
