Kubernetes Learning Roadmap
Importance of Kubernetes Knowledge
- Rapid adoption by companies
- Potential for specialized career as a Kubernetes engineer
- Complexity leads to a steep learning curve
- Need for a structured roadmap to learn efficiently
Understanding Kubernetes
- Two primary roles: Platform Administration and Platform User
- Administration: Set up, initialize, configure the platform
- Platform User: Deploy applications and services
- Differentiation helps focus learning based on role (Developer or Operations Engineer)
Certifications
- CKA: Kubernetes Administrator
- CKAD: Kubernetes Application Developer
Shared Foundation for Learning
- Understand the "Why" of Kubernetes
- Solves issues of operating large, containerized applications
- Core Components and Architecture
- Control plane, worker nodes
- Components: Pod, Service, ConfigMap, Secret, Ingress, Deployments, StatefulSets, Namespaces, Volumes
- Background Components
- Scheduler, Controller, etcd, Kubelet, container runtime
Practical Skills and Tools
- Kubectl CLI
- Essential commands for interacting with the cluster
- Kubernetes Manifest Files
- YAML configuration files for defining application states
- Troubleshooting Skills
- Use of Kubectl for debugging and analyzing cluster issues
Common Pitfalls and Best Practices
- Avoid common misconfigurations
- Learn bad practices to know what to avoid
Advanced Topics
- Helm Charts
- Deployment of third-party services
Kubernetes Administrator Roadmap
- Cluster Operations
- Self-managed vs Managed services (AWS EKS, Azure AKS)
- Networking
- Ingress, Network Policies, Pod communication, Cluster DNS
- Access Management
- Role-Based Access Control (RBAC)
- Data Management
- Kubernetes Volumes and etcd
- Operators
- Automation of complex applications
- Monitoring and Best Practices
- Use tools like Prometheus, learn best practices for operations and security
Kubernetes User Roadmap
- Application Deployment
- High availability, scaling, Deployment configurations
- Deployment Strategies
- Canary, blue-green deployments, rolling updates
- Continuous Integration/Continuous Deployment (CI/CD)
- Integrate with Kubernetes for automated deployments
Additional Learning Resources
- Use of pre-structured courses for efficient learning
- Free videos on YouTube for foundational knowledge
- Advanced courses for in-depth understanding
Conclusion
- Follow the roadmap step-by-step
- Practice with open-source applications in Kubernetes
- Use structured resources for guided learning
This roadmap aims to provide a clear structure for learning Kubernetes, focusing on both theory and practical skills, tailored to specific roles and career paths in the industry.
