What containerization and orchestration systems do you know?

I am familiar with several containerization and orchestration systems:

• Docker — the primary containerization system that allows packaging applications with their dependencies into isolated containers.
• Kubernetes — a popular container orchestration system that manages deployment, scaling, and maintenance of containerized applications.
• Docker Swarm — an orchestration tool built into Docker, simpler compared to Kubernetes.

Example of using Kubernetes to deploy an application:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: myapp-deployment
spec:
  replicas: 3
  selector:
    matchLabels:
      app: myapp
  template:
    metadata:
      labels:
        app: myapp
    spec:
      containers:
      - name: myapp-container
        image: myapp:latest
        ports:
        - containerPort: 80

This allows automatic management of the number of running instances of the application and updating them without downtime.
