Complete Missing Components for Epic #8 Container Execution Engine

Issue Summary

Epic #8 "Container Execution Engine" has all 4 sub-issues completed (#9, #10, #11, #12), but there are critical missing components that prevent full epic completion and deployment.

Parent Epic

Contributes to Epic #8: Container Execution Engine

Current Status ✅

• ✅ Complete Docker executor with security controls
• ✅ Comprehensive security validation and container hardening
• ✅ Full logging system with real-time streaming and storage
• ✅ Robust error handling with retry logic and cleanup
• ✅ Worker management with concurrency control
• ✅ Queue system with Redis and dead letter handling
• ✅ Monitoring & resilience with circuit breakers

Missing Components ❌

1. Container Executor Images (Critical Priority)

Issue: Security manager validates against python:3.11-alpine, etc. but custom executor images don't exist
Required:

• Create /images/python-executor/Dockerfile with security hardening
• Create /images/bash-executor/Dockerfile with security hardening
• Create /images/javascript-executor/Dockerfile with security hardening
• Images must include non-root user (UID 1000:1000), minimal packages, security restrictions
  Impact: Cannot execute real containers - deployment blocked

2. Security Profiles (Critical Priority)

Issue: Code references seccomp profiles but actual profile files don't exist
Required:

• Create actual seccomp profile JSON at expected locations
• Validate profiles restrict dangerous system calls per Issue Docker Client Integration and Security Configuration #9 specifications
• Test profile enforcement in containers
  Impact: Security controls not functional

3. Real Container Integration Tests (High Priority)

Issue: All tests use mock executor - no validation of actual Docker execution
Required:

• Integration tests with real Docker containers
• Validate security controls work with actual container execution
• Test resource limits, timeouts, cleanup with real containers
• Prove container isolation and security enforcement
  Impact: Unknown if implementation works with real containers

4. Performance Benchmark Validation (Medium Priority)

Issue: Epic #8 success criteria: "Container execution under 5 seconds for cold starts"
Required:

• Performance test suite measuring cold start times
• Benchmark container creation, execution, cleanup latency
• Validate meets 5-second requirement
  Impact: Success criteria not verified

5. Security Penetration Testing (Medium Priority)

Issue: Epic #8 success criteria: "Zero security incidents in isolation testing"
Required:

• Comprehensive security test suite with malicious code attempts
• Test container escape attempts, resource exhaustion attacks
• Validate script content filtering effectiveness
• Document security test results
  Impact: Security effectiveness not proven

6. Security Documentation (Low Priority)

Issue: Epic #8 completion criteria: "Documentation updated with security guidelines"
Required:

• Security deployment guide
• Container security configuration documentation
• Operational security guidelines
  Impact: Deployment and operational guidance missing

Acceptance Criteria

• All container executor images built and tested
• Seccomp profiles created and validated
• Integration tests pass with real Docker containers
• Performance benchmarks meet <5s cold start requirement
• Security penetration tests pass with zero incidents
• Security documentation complete and reviewed

Definition of Done

• Can deploy and run actual container execution (not mocked)
• Security controls verified through real container testing
• Performance requirements validated through benchmarks
• All Epic Container Execution Engine #8 acceptance criteria satisfied
• Security documentation reviewed and approved
• Epic Container Execution Engine #8 can be marked as complete

Technical Priority

Critical - Blocks Epic #8 completion and production deployment. The excellent core implementation just needs these final components to be fully functional.

Estimated Effort

• Container Images: 2-3 days
• Security Profiles: 1 day
• Integration Tests: 2-3 days
• Performance/Security Testing: 1-2 days
• Documentation: 1 day

Total: ~7-10 days
