Do you have practical experience using Kubernetes in your projects?

Yes, I have practical experience using Kubernetes in projects. I have worked with deploying applications in a cluster, configuring manifests for Deployment, Service, ConfigMap, and Secret, as well as scaling and updating applications without downtime.

Additionally, I am familiar with cluster state management basics, pod monitoring, and logging. I have used Helm for package management and written simple YAML manifests for deployment automation.

Example of a simple 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: 80

This manifest creates 3 replicas of the application, ensuring fault tolerance and scalability.
