What is Kubernetes?

Kubernetes (often called K8s) is an open-source container orchestration system. It automates the deployment, scaling, and management of containerized applications. Think of it as the conductor of your containerized orchestra, ensuring everything runs smoothly.

Kubernetes allows you to:

• Deploy applications in containers
• Scale your applications based on demand
• Manage updates and rollbacks
• Automate tasks like networking and storage

Key Concepts

Let's explore some of the core concepts:

• Pods: The smallest deployable unit in Kubernetes, containing one or more containers.
• Nodes: A worker machine that runs pods.
• Clusters: A set of nodes that work together to run your applications.
• Deployments: Declarative specifications for desired state of your applications.
• Services: An abstraction that defines how to expose your applications.

                  
                  # Example Deployment YAML
                  apiVersion: apps/v1
                  kind: Deployment
                  metadata:
                    name: my-app
                  spec:
                    replicas: 3
                    selector:
                      matchLabels:
                        app: my-app
                    template:
                      metadata:
                        labels:
                          app: my-app
                      containers:
                        - name: my-app
                          image: nginx
                          ports:
                            - containerPort: 80
