⚡ 5-Minute Quick Start

Step 1: Build & Start

cd /workspaces/teachLink_backend
npm install
npm run start:dev

Step 2: Create Test Incident

curl -X POST http://localhost:3000/incidents \
  -H 'Content-Type: application/json' \
  -d '{
    "title": "Database Performance Degradation",
    "description": "Query duration exceeded threshold",
    "severity": "critical",
    "runbookId": "database-failure"
  }'

Step 3: View Incident

curl http://localhost:3000/incidents

Step 4: Execute Remediation

# Get incident ID from above
INCIDENT_ID="<your-incident-id>"

curl -X POST http://localhost:3000/incidents/$INCIDENT_ID/remediation-actions \
  -H 'Content-Type: application/json' \
  -d '{
    "actionType": "restart_service",
    "description": "Restart API service",
    "parameters": {"serviceName": "api-server"}
  }'

Step 5: Run Runbook

curl -X POST http://localhost:3000/incidents/$INCIDENT_ID/runbook-executions \
  -H 'Content-Type: application/json' \
  -d '{
    "runbookName": "database-failure",
    "runbookPath": "dr/runbooks/database-failure.md"
  }'
