KubeDay Colombia 2024

In this comprehensive session, "Mastering Kubernetes Operators with KubeBuilder: Sending Metrics to Prometheus," you will learn how to build and deploy a Kubernetes operator using KubeBuilder, an advanced framework for building Kubernetes APIs. This talk will walk you through the entire process of creating a custom operator, from the initial setup to handling complex resource management. Once your operator is up and running, we will delve into monitoring and observability by integrating it with Prometheus, a leading open-source systems monitoring and alerting toolkit. You will learn how to expose custom metrics from your operator and configure Prometheus to scrape these metrics, providing valuable insights into the health and performance of your Kubernetes workloads.

Modern applications, especially those running on containerized platforms like Kubernetes, demand a high level of observability to ensure performance, security, and stability. DevOps practices are crucial, but achieving true visibility into complex Kubernetes environments can be challenging. This talk introduces the concept of Observability Maturity specifically within the context of Kubernetes and OpenTelemetry. We'll explore how to leverage OpenTelemetry, a vendor-neutral observability framework, to instrument your Kubernetes applications and achieve a mature level of observability.
