Mastering Fluent Bit: Developer Guide to Telemetry Pipeline Routing

This series is a general purpose getting started guide for those of us wanting to learn about the Cloud Native Computing Foundation (CNCF) project Fluent Bit.

Each article in this series addresses a single topic by providing insights into what the topic is, why we are interested in exploring that topic, where to get started with the topic, and how to get hands-on with learning about the topic as it relates to the Fluent Bit project.

The idea is that each article can stand on its own, but that they also lead down a path that slowly increases our abilities to implement solutions with Fluent Bit telemetry pipelines.

Let's take a look at the topic of this article, using Fluent Bit routing for developers. In case you missed the previous article, check out the top three telemetry pipeline filters where you explore the most useful filters for manipulating and controlling your telemetry data.

This article will be a hands-on exploration of routing patterns that help you as a developer building sophisticated telemetry pipelines. We'll look at how to direct telemetry data to different destinations based on tags, patterns, and conditions in your Fluent Bit configurations.
