The OpenTelemetry (OTel) Operator is a powerful tool for managing the deployment and configuration of OpenTelemetry Collectors in Kubernetes, offering capabilities for automating telemetry data collection without modifying application source code. This blog post, co-authored by Reese Lee, provides an in-depth look at the Operator's functionalities, including the use of the Open Agent Management Protocol for consistent observability settings and the automatic injection of zero-code instrumentation into Kubernetes pods. It guides users through installation prerequisites, such as the necessity of having a cert-manager and a compatible Kubernetes cluster, and offers troubleshooting advice for common issues encountered during installation, Collector deployment, and auto-instrumentation. Additionally, it explains how to deploy and configure the OpenTelemetryCollector resource, manage different API versions and base images, and ensure proper endpoint configurations for telemetry data export. The post also covers the use of Instrumentation resources to facilitate auto-instrumentation and provides strategies for resolving instrumentation issues, making it a comprehensive guide for leveraging the Operator to enhance observability in Kubernetes environments.
