Kubernetes Logging: Deploying and Managing the EFK Stack

Managing logs in a distributed Kubernetes environment can be overwhelming without the right tools. Implementing a centralized logging pipeline is essential for maintaining application health, troubleshooting errors, and gaining deep operational insights. This text-based course guides you through the foundational concepts and practical steps to deploy, configure, and maintain the EFK (Elasticsearch, Fluentd, Kibana) stack. You will transition from understanding basic log flows to managing a robust, production-ready logging architecture. What you'll learn: - Understand the core concepts of centralized logging, log collection, and the role of each EFK component. - Deploy and configure Elasticsearch as a resilient, scalable search and analytics engine within Kubernetes. - Configure Fluentd as a DaemonSet to automatically collect, parse, and route container logs in structured JSON format. - Design Kibana dashboards to visualize log data, build search queries, and monitor system health. - Apply modern security practices including Role-Based Access Control (RBAC) and basic TLS encryption for your logging pipeline. - Implement log rotation, index lifecycle management, and troubleshooting techniques for common pipeline bottlenecks. You will start with essential logging definitions and architectural foundations before moving step-by-step through configuration files and deployment manifests. Through detailed written explanations and structured configuration exercises, you will learn how to scale and secure the entire pipeline. This course is designed for beginner DevOps engineers, system administrators, and developers who want to learn centralized logging from scratch. No prior experience with the EFK stack is required, though a basic familiarity with Kubernetes concepts is helpful.
