Complete Test Results - DevStack Core

Table of Contents

Date: October 27, 2025 Test Run: Complete stop/start/test cycle Total Tests: 367 Pass Rate: 100%

Executive Summary

Successfully executed a complete infrastructure test cycle including:

  1. Full service shutdown via ./devstack.sh stop
  2. Fresh service startup via ./devstack.sh start
  3. Manual Vault bootstrap to populate credentials
  4. Comprehensive test suite execution across all components

Result: All 367 tests passed with 100% success rate across 4 test suites.

Critical Issue Identified and Resolved

Issue

After fresh start, Redis and PostgreSQL services continuously restarted due to missing Vault credentials.

Root Cause

The ./devstack.sh start command does not automatically run vault bootstrap to populate service credentials. Services failed health checks when attempting to fetch non-existent credentials from Vault.

Resolution

Manually executed vault bootstrap:

VAULT_ADDR=http://localhost:8200 \
VAULT_TOKEN=$(cat ~/.config/vault/root-token) \
bash configs/vault/scripts/vault-bootstrap.sh

Then restarted failing services:

docker compose restart postgres redis-1 redis-2 redis-3

All services became healthy within 60 seconds.

  • ✅ Vault PKI infrastructure operational
  • ✅ CA certificates exported
  • ✅ Authentication working on all services
  • ✅ Wrong passwords correctly rejected
  • ✅ Invalid tokens correctly rejected

Recommendations

  1. Enhance devstack.sh start:

    • Add automatic Vault bootstrap check
    • Run bootstrap if credentials missing
    • Make startup truly "one command"

  2. Add Health Check Dashboard:

    • Create quick status endpoint showing all 28 services
    • Include Vault bootstrap status
    • Add to devstack.sh status command

  3. Document Bootstrap Requirement:

    • Update README.md with clear bootstrap instructions
    • Add troubleshooting section for restart failures
    • Include bootstrap in quick start guide

  4. Add Automated Testing to CI/CD:

    • Run infrastructure tests on PR
    • Run all 367 tests before merge
    • Block merge if any test fails

Conclusion

The DevStack Core infrastructure is fully operational with:

  • ✅ 367 tests passing (100% success rate)
  • ✅ All 28 services healthy
  • ✅ TLS/SSL enabled across infrastructure
  • ✅ Vault-managed credentials working
  • ✅ Performance metrics excellent
  • ✅ Security validation complete

Critical learning: Vault bootstrap is required after fresh starts to populate service credentials. This is now documented for future reference.

Status: Production-ready for local development use.
