From Days to Hours: Accelerated K8s Debugging with Rovo Dev CLI

This post details the application of the Rovo Dev CLI to debug a production issue involving GCP Ingress and OpenSearch. The Rovo Dev CLI was used to analyze Jira tickets and Confluence documentation, enable GCP Load Balancer logging, identify a subtle Host header mismatch (':443' suffix) causing 404 errors, and generate a reproducible test case. The fix involved configuring a default backend for the GKE ingress to route unmatched requests to OpenSearch. The post emphasizes the speed, repeatability, knowledge sharing, and gap-filling benefits of using the Rovo Dev CLI for debugging complex infrastructure issues.
