Kubernetes – Container Orchestration

Kubernetes is the industry-standard container orchestration platform for automating deployment, scaling, and management of containerized applications. Originally developed by Google, it is now maintained by the Cloud Native Computing Foundation.

Key Features

• Auto-Scaling: Scale containers based on demand
• Self-Healing: Automatic container restart and replacement
• Service Discovery: Built-in DNS and load balancing
• Rolling Updates: Zero-downtime deployments
• Secret Management: Secure configuration handling

Installation

Install kubectl and minikube for local development:

# Install kubectl
curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"
sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl

# Install minikube
curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
sudo install minikube-linux-amd64 /usr/local/bin/minikube

Usage Examples

Deploy an application:

apiVersion: apps/v1
kind: Deployment
metadata:
