Kubernetes Logs ➡️ FluentBit ➡️ Grafana Loki (The Easy Way!) #observability #grafana #logging

In this video, we dive deep into Kubernetes logging and walk through how to build an efficient log data pipeline. You'll learn the core concepts of Fluent Bit, what a data pipeline actually is, and how to seamlessly send your K8s cluster logs to Grafana Loki for centralized monitoring. Whether you are a DevOps engineer or just getting started with cloud-native observability, this step-by-step tutorial will help you set up production-ready logging in minutes! 🚀 What we cover in this video: 00:00 - Introduction & Recap of Previous Grafana Loki Deployment Modes 00:27 - When to Use Microservices vs. Single Binary Deployment Modes 00:59 - Overview of Today's Demo Setup (Multi-Cluster Logging Flow) 01:31 - Alternative Logging Agents (CloudWatch, OpenSearch, Splunk) 01:59 - What is a Data Pipeline in Fluent Bit? 02:42 - Fluent Bit Core Concepts: Inputs & Plugins (Tail vs. HTTP) 03:45 - Fluent Bit Core Concepts: Processors (Masking Sensitive/PII Data) 04:39 - Fluent Bit Core Concepts: Parsers (Structuring Unstructured Logs) 05:12 - Fluent Bit Core Concepts: Filters (Enriching Logs with Metadata) 06:21 - Fluent Bit Core Concepts: Buffers (Memory vs. File System Storage) 06:53 - Why Do We Need Buffers?
