This update refines the Tor relay configuration and build process:
- Security: Disables DirPort and adopts ciissversion:2 for ContactInfo.
- Performance: Adds IPv6 support and hardware acceleration options.
- Builds: Establishes Stable vs. Edge variants for better testing cycles.
- Tooling: Integrates nyx.config and cleans up legacy tags.
- Sync: Aligns cosmos-compose and docker-compose templates.
- Update retention policy: Keep last 7 versions
No breaking changes introduced.
🚀 Major architectural release with a near full rewrite of the entrypoint, validation system, diagnostics, and templates. The image is now ~20MB, fully busybox based, more secure, and more flexible for relay and bridge operators.
🔧 Critical Fixes
- Busybox compatible rewrite of OBFS4V_* parsing for values with spaces.
- Rewritten TOR_CONTACT_INFO validation to prevent crash loops.
- Restored bootstrap logs with Log notice stdout.
- Fixed ENV healthchecks and validation order.
- Resolved busybox regex and quoting issues across the script.
✨ Features and Enhancements
- Added PT_PORT with complete obfs4 bridge compatibility.
- Support for OR_PORT, PT_PORT, EMAIL, and NICKNAME.
- Rewritten bandwidth logic with correct Rate and Burst translation.
- Unified guard, exit, and bridge via TOR_RELAY_MODE.
- Integrated obfs4 with rewritten diagnostics for status, health, fingerprint, and bridge-line.
- Reliable ENV only mode without torrc files.
📦 Build Improvements
- Image reduced ~45MB to ~20MB with busybox only tools.
- Rewritten healthcheck for ENV and mounted configs.
- Four diagnostic tools rewritten to pure busybox sh.
- Weekly rebuilds with latest Alpine and Tor.
📚 Templates and Documentation
- All templates rewritten and updated with bandwidth options and naming alternatives.
- Updated Cosmos and Docker Compose templates for bridge, guard, exit.
- New templates README with full deployment, migration, and config comparisons.
- Revised Claude file with clearer differences and bandwidth notes.
🔒 Security Hardening
- 32 vulnerabilities fixed across critical, high, medium, low categories.
- Non root runtime with UID 100.
- Strict OBFS4V_* whitelist and rewritten validation.
- No exposed diagnostics ports, docker exec only.
- Smaller attack surface with removed binaries.
🚀 Migration Notes
- From v1.1.0: direct upgrade, no config changes, fingerprint preserved.
- From official obfs4 bridge: one time UID fix required, full ENV compatibility afterward.
- Templates include both TOR_ and official naming for smooth migration.
🧩 Compatibility
- Alpine 3.22.2 base, latest Tor from edge.
- AMD64 and ARM64 supported.
- Works with Docker, Compose, Cosmos Cloud, Portainer.
