An engineer used the RovoDev CLI to cut a hard‑to‑reproduce Kubernetes/GKE ingress incident from three days of multi‑team debugging down to about an hour. The post walks through how RovoDev connects to Jira and Confluence for context, drives targeted GCP and Kubernetes investigations, surfaces a subtle Host‑header/ingress rule mismatch causing 404s, and turns the fix into a repeatable, shareable workflow for future K8s debugging.

An engineer used Atlassian's Rovo Dev CLI to resolve a hard-to-reproduce Kubernetes/GKE ingress issue that had stumped five engineers for three days. By connecting Rovo Dev to Jira and Confluence for context, enabling GCP load balancer logging, and systematically comparing HTTP requests, the root cause was identified in about one hour: Apache HttpClient was appending ':443' to the Host header, causing requests to bypass named ingress rules and hit the default backend with 404 errors. The fix was a simple GKE ingress default backend configuration. The post highlights how Rovo Dev accelerated diagnosis by bridging knowledge gaps, making the workflow repeatable, and producing shareable artifacts like test programs and Confluence documentation.
