In what cases can Kubernetes be used?

• Microservices architecture: Convenient management and scaling of multiple independent services.
• High availability: Automatic restart of failed pods, replication.
• Scalability: Flexible horizontal and vertical scaling of applications depending on load.
• Continuous Integration and Delivery (CI/CD): Simplifies deployment and updating of applications.
• Efficient resource utilization: Optimal load distribution among cluster nodes.
• Multi-cloud and hybrid scenarios: Unified platform for managing applications across different environments.
• Batch and long-running tasks: Launch and orchestration of various types of workloads.
• Stateful applications management: Support for statefulsets for applications requiring persistent data storage.

Examples of deployment management commands:

# Example deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-app
spec:
  replicas: 3  # Number of pod replicas
  selector:
    matchLabels:
      app: my-app
  template:
    metadata:
      labels:
        app: my-app
    spec:
      containers:
      - name: my-app-container
        image: my-docker-repo/my-app:latest # Application image
        ports:
        - containerPort: 80 # Application port

# Applying the manifest
kubectl apply -f deployment.yaml
