This project is a proof of concept for Red Hat OpenShift Advanced Cluster Administration. It demonstrates the installation and configuration of the OpenTelemetry Collector provided by Red Hat, in a Hub and Spoke cluster setup. This setup involves creating one OpenTelemetry Collector in each spoke cluster that forwards data to a central OpenTelemetry Collector in the hub cluster.

• OpenTelemetry Collector Installation: Automates the deployment of the OpenTelemetry Collector Build by Red Hat in both Hub and Spoke clusters.
• Cluster Configuration: Configures each spoke cluster's OpenTelemetry Collector to send data to the central collector in the hub cluster.
• OpenShift Route Exposure: Exposes the OpenTelemetry Collector from the Hub Cluster via an OpenShift Route for accessible monitoring and management.
• Certificate generation: Generation and configuation of certificates to communicate and authenticate hte OpenTelemetry Collectors.

• 1 Red Hat OpenShift Cluster connected with RHACM installed
• 1 Red Hat OpenShift Cluster added as spoke cluster whose name is cluster1.

1. Clone the repository.
2. Change the enpoint field in cmd/manifests/otel.yaml to the URL where the collector will be available in your Hub cluster.
3. Run make demo IMG=<image name>.
