By the end of this course, you will be able to:
- ✅ Understand Kubernetes architecture and components
- ✅ Deploy and manage containerized applications
- ✅ Configure networking with Services and Ingress
- ✅ Manage configuration and secrets securely
- ✅ Implement persistent storage solutions
- ✅ Set up resource quotas and limits
- ✅ Run batch jobs and scheduled tasks
- ✅ Deploy stateful applications
- ✅ Implement RBAC and security best practices
- ✅ Use Helm for package management
- ✅ Set up monitoring and logging
- ✅ Troubleshoot common issues
Before starting, you should have:
- Basic understanding of containers (Docker)
- Command line experience
- A local Kubernetes cluster (see setup below)
# Option 1: Minikube
brew install minikube # macOS
minikube start
# Option 2: Docker Desktop
# Enable Kubernetes in Docker Desktop settings
# Option 3: Kind (Kubernetes in Docker)
brew install kind
kind create cluster
# Verify installation
kubectl cluster-info
kubectl get nodes- Follow in order - Each day builds on previous concepts
- Read the theory - Understand the "why" before the "how"
- Type the examples - Don't just copy-paste, type them out
- Experiment - Modify examples and see what happens
- Use the commands - Practice kubectl commands regularly

Ready to begin? Start with Day 1: Introduction to Kubernetes!
- All YAML examples are ready to use - just
kubectl apply -f - Each day includes practical examples and best practices
- Diagrams use ASCII art for universal compatibility
- Commands are tested on Kubernetes 1.28+
Happy Learning! 🎉
