Do you have practical experience working with Kubernetes and its main components?

Yes, practical experience with Kubernetes includes setting up and managing clusters, deploying applications using YAML manifests, working with core objects like Pod, Deployment, Service, ConfigMap, Secret. Also, monitoring cluster health and scaling applications.

A basic Deployment example:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: example-deployment
spec:
  replicas: 3
  selector:
    matchLabels:
      app: example
  template:
    metadata:
      labels:
        app: example
    spec:
      containers:
      - name: example-container
        image: nginx:latest

Main Kubernetes components:

• kube-apiserver — API server for cluster interaction
• etcd — distributed configuration storage
• kube-scheduler — task scheduler
• kube-controller-manager — controllers for state management
• kubelet — agent on each node to run containers
• kube-proxy — network proxy for services

Experience with these components enables efficient management of containerized applications.
