About Kubernetes — how did it work?

Working with Kubernetes involved deploying and managing containerized applications in a cluster. I created and configured manifests in YAML format to describe pods, deployments, services, and other resources.

I also handled scaling applications using Horizontal Pod Autoscaler, monitoring cluster health, and logging. I used kubectl for resource management and Helm for package management.

An example of a simple deployment:

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: 80

Overall, experience with Kubernetes helped me better understand container orchestration principles and ensure the reliability and scalability of applications.
