90 Days DevOps Challenge | Day 26 | Kubernetes Volumes, ConfigMaps & Secrets Explained
Welcome to Day 26 of the 90 Days DevOps Challenge! ☸️
In this session, we’re exploring three powerful Kubernetes concepts: Volumes, ConfigMaps, and Secrets — essentials for managing state, configuration, and sensitive data inside your containers.
🔍 What You'll Learn Today:
✅ Why Kubernetes needs Volumes (vs container storage)
✅ Types of Kubernetes Volumes: emptyDir, hostPath, persistentVolumeClaim
✅ How to mount a volume into a pod
✅ What are ConfigMaps and how to create them
✅ Injecting configuration using environment variables and volumes
✅ Storing and accessing sensitive data with Kubernetes Secrets
✅ Best practices for security and configuration management
✅ Real-world examples using YAML
This video bridges the gap between stateless containers and real production apps by introducing how to handle persistent data and environment-specific configs in Kubernetes.
