Tell about your experience using Kubernetes in projects.

In projects using Kubernetes, I worked with deploying and managing containerized applications. The main tasks included:

• Creating and configuring manifests (Deployment, Service, ConfigMap, Secret) to describe resources.
• Setting up application scaling using ReplicaSets and Horizontal Pod Autoscaler.
• Monitoring pod status and logging through built-in Kubernetes tools and external systems (Prometheus, Grafana).
• Updating applications with minimal downtime (rolling updates).
• Managing configurations and secrets for secure data storage.

An example of a simple Deployment for a Python application:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: python-app
spec:
  replicas: 3
  selector:
    matchLabels:
      app: python-app
  template:
    metadata:
      labels:
        app: python-app
    spec:
      containers:
      - name: python-container
        image: myregistry/python-app:latest
        ports:
        - containerPort: 5000

This experience allows for effective use of Kubernetes for microservices orchestration and ensuring high availability of applications.
