Audio N/AQuick interview answer
Debug GitOps (Argo CD / Flux) by confirming blast radius, checking lag/error metrics, grabbing profiles/traces, then mitigating before deep root-cause. Baseline: Desired cluster state lives in Git; controller reconciles continuously. CI builds images; CD is pull-based sync from Git.
Detailed answer
Production debug playbook for GitOps (Argo CD / Flux): 1) Stabilize: rate-limit, shed load, or roll back if users are hurting. 2) Orient: dashboards for latency, errors, saturation tied to GitOps (Argo CD / Flux). 3) Evidence: traces, profiles, logs with correlation IDs. 4) Hypothesize + prove with a safe experiment. 5) Fix + add a regression test/alert so it cannot silently return. Watch for: kubectl apply snowflakes bypassing Git. Parent context: Baseline: Desired cluster state lives in Git; controller reconciles continuously. CI builds images; CD is pull-based sync from Git.
