Production Broke.
You’re On Call.
No slides. No multiple-choice quizzes. Diagnose and remediate real production incidents in disposable infrastructure environments.
Your first outage should not be your first rehearsal.
Production incidents punish hesitation. VibeInfra turns incident response into deliberate practice: short, realistic drills that build calm debugging reflexes before the pager goes off.

Free Kubernetes lab starts in ~30 seconds
No credit card · no local setup · disposable infra
Not a toy terminal. A complete incident rehearsal environment.
Every lab exposes the same evidence chain engineers use in real incidents, then grades the recovery with explicit checks.
Ephemeral K3s / container sandbox
Fresh disposable infrastructure for every drill.
Web terminal with real commands
kubectl, logs, events, manifests, and patch application.
Traffic + error pressure
HTTP 503s, latency spikes, retry storms, and service health signals.
Automated validation gates
Readiness, HTTP 200, error rate, and sustained recovery checks.
After-action report
Root cause, fix timeline, commands used, and recovery proof.
Scenario manifests
Broken deployments, probes, secrets, queues, pools, and config drift.
Every drill ends with evidence, not vibes.
The goal is not clicking through a lesson. The goal is a verified recovery result your team can trust, discuss, and improve.
vibeinfra-checkout — recovery validation
✓ readiness probe passing
✓ HTTP 200 restored
✓ error rate 0.0% for 30s
✓ p99 latency below SLO
✓ after-action report generated
Root cause captured. Fix recorded. Recovery proven.
Each result becomes a training artifact for onboarding, interviews, game days, and runbook improvement.
The Canonical 7-Step Incident Remediation Lifecycle
Real production outages are never solved with 1-command toy fixes. Every VibeInfra incident drill trains engineers in the full outside-in SRE recovery lifecycle.
Traffic Shedding & Triage
Activate edge rate-limiting and circuit breakers immediately to halt client retry storms before diagnosis.
Blast Radius Isolation
Cordon degraded worker nodes and isolate poisoned pods with NetworkPolicies to prevent cascading failure.
Data Tier & Pool Unclog
Clear database connection pool saturation, terminate deadlocked transactions, and relieve IO bottlenecks.
Targeted Root Cause Patch
Apply targeted declarative fixes directly in Kubernetes manifests, ConfigMaps, Secrets, or schema migrations.
Queue Drain & State Reconcile
Purge poisoned Dead Letter Queues (DLQ), flush corrupt cache keys, and synchronize distributed state.
Controlled Scale-Up
Incrementally scale replica sets (1 → 3 → 5) to warm connection pools and prevent thundering herd crashes.
Sustained Traffic Gate & AAR
Gate resolution on ≥30s continuous loadgen traffic with 0% error rate, generating an automated After-Action Review.
