Summary

Transforms the SRE Agent testing experience from slow local builds (10-15 minutes) to instant deployment with pre-built public images (2-5 minutes), while maintaining security options for production use.

🚀 Key Improvements

Fast Testing Mode

  • New compose.ghcr.yaml: Uses public GitHub Container Registry images
  • No authentication required: Instant access for new users
  • Full functionality: All 7 services (orchestrator, LLM, firewall, MCP servers) included
  • 2-5 minutes deployment vs 10-15 minutes for local builds

Enhanced Build Script

  • Multi-registry support: ./build_push_docker.sh --ghcr < /dev/null | --aws|--gcp|--dockerhub|--local
  • Security option: --local builds without pushing for security-conscious users
  • Clear documentation: Usage instructions and requirements for each registry

Automated Public Image Publishing

  • GitHub Actions enhancement: Dual-publish to ECR (private) + GHCR (public)
  • Automatic triggers: On main branch pushes and releases
  • No secrets required: Uses built-in GITHUB_TOKEN for GHCR publishing

Improved User Experience

  • New "quick" mode in setup_credentials.py (fastest option)
  • Updated documentation: README and CLAUDE.md prioritise fast deployment
  • Clear migration path: From testing to production deployment

📋 Test Plan

  • Verify compose.ghcr.yaml configuration matches existing functionality
  • Test enhanced build script with all registry targets
  • Confirm GitHub Actions workflow additions
  • Validate credential setup script quick mode
  • Check documentation accuracy and clarity

🔒 Security Considerations

  • Public images contain identical open-source code (no security difference vs private)
  • Build-your-own option clearly documented for maximum security
  • Multiple deployment paths: Testing → minimal → full → production
  • No breaking changes to existing production workflows

🎯 Impact

Before:

  • New users faced 10-15 minute barrier to try SRE Agent
  • Complex setup required for basic testing
  • High friction for adoption

After:

  • 2-5 minute evaluation experience
  • Single command deployment: docker compose -f compose.ghcr.yaml up
  • Lower barrier to adoption while maintaining security options

Usage

Fastest Way to Try SRE Agent

uv run python setup_credentials.py --mode quick
docker compose -f compose.ghcr.yaml up

For Security-Conscious Users

./build_push_docker.sh --local
docker compose -f compose.aws.yaml up --build

This change significantly improves the new user experience while maintaining all existing functionality and security options.

Clarify compose.tests.yaml purpose and accurate build times
ad898a5 
- Update documentation to reflect that testing mode builds containers locally (~10-15 minutes)
- Remove misleading '2 minute setup' claim for testing mode
- Add clear comments to compose.tests.yaml explaining its purpose and limitations
- Emphasize that testing mode eliminates cloud setup complexity, not build time
- Add --build flag to ensure fresh builds when needed

Purpose of compose.tests.yaml:
- Local development and CI testing
- Mock LLM provider (no real API calls)
- Minimal credential requirements (only HF_TOKEN)
- Missing cloud integrations (Slack, GitHub, K8s) for simplicity

Add fast testing mode with public GHCR images
e13a8cf 
Transform SRE Agent testing from 10-15 minute builds to 2-5 minute deployment using pre-built public images from GitHub Container Registry.

Key improvements:
- Add compose.ghcr.yaml for instant deployment with public images
- Enhance build_push_docker.sh with multi-registry support (GHCR, Docker Hub, local builds)
- Add GHCR publishing to GitHub Actions workflow for automated public image builds
- Introduce "quick" mode in setup_credentials.py for fastest testing experience
- Update documentation to prioritise fast deployment options
- Maintain security options for building custom images

Benefits:
- 🚀 2-5 minutes vs 10-15 minutes deployment time
- 🔓 No authentication barriers for testing
- 🛠️ Full SRE functionality (all MCP servers included)
- 🔒 Clear build-your-own options for security-conscious users
