Yes, Docker Secret Operator uses semantic versioning (MAJOR.MINOR.PATCH) for unique version identification.

Current release: v3.5.17

Versioning scheme:

• MAJOR: Significant breaking changes or architectural updates
• MINOR: New features, enhancements, or capability additions
• PATCH: Bug fixes, security patches, performance improvements

Version management:

• Versions are tracked as git tags in the GitHub repository (github.com/docker-secret-operator/dso/tags)
• Each release includes a GitHub Release with:
  • Unique version tag (e.g., v3.5.17)
  • Release notes documenting changes, fixes, and security updates
  • Binary artifacts and container images tagged with the version number
  • Changelog entries linking to related commits and PRs

Users can access specific versions via:

• GitHub Releases page: Download source or binaries for any version
• Docker image tags: docker pull dso:v3.5.17
• Git tags: git checkout v3.5.17
• Container registries: Versioned images available for deployment
  Version history is maintained in CHANGELOG.md showing all released versions with their features and fixes.

Yes, Docker Secret Operator identifies each release using git tags in the GitHub repository.

Git tag naming convention: v{MAJOR}.{MINOR}.{PATCH}

Examples of release tags:

• v3.5.17 (current release)
• v3.5.16 (previous patch release)
• v3.5.0 (feature release)
• v3.4.x (previous minor versions)

How releases are tagged:

1. Development occurs on main branch with regular commits
2. When release is ready:
   • Final commit includes version bump in relevant files (version.go, README.md, etc.)
   • Annotated git tag is created: git tag -a v3.5.17 -m "Release v3.5.17"
   • Tag is pushed to GitHub: git push origin v3.5.17
3. GitHub automatically creates Release entry from the git tag
4. Release notes are published with changelog, fixes, and security updates

Accessing tagged releases:

• Users can view all tags: github.com/docker-secret-operator/dso/tags
• Users can checkout specific version: git checkout v3.5.17
• Users can clone specific version: git clone --branch v3.5.17 https://github.com/docker-secret-operator/dso.git
• Users can pull versioned container images: docker pull dso:v3.5.17

Relationship to GitHub Releases:

• Each git tag v3.x.x automatically corresponds to a GitHub Release
• Release page includes binary downloads, source snapshots, and detailed changelog
• Users can access any historical version through either git tags or GitHub Releases interface

This approach ensures:

• Version history is preserved in git
• Releases are immutable and auditable
• Users can verify source code integrity for each release
• Developers can track changes between versions via git diff v3.5.16..v3.5.17

• Automated enforcement via GitHub Actions (coverage gating)

Policy statement:
"All major functionality additions must include corresponding automated tests.
Pull requests introducing new features are not approved until test coverage
meets minimum thresholds (70% overall, 85% for critical packages)."

Implementation:

1. Code Review: Core Maintainers verify test coverage during PR review
2. Automated Gating: GitHub Actions blocks merge if coverage decreases
3. Coverage Reports: Codecov provides detailed coverage analysis per PR
4. Documentation: CONTRIBUTING.md explains test requirements

Enforcement examples:

• New provider added → Must include provider tests (*_provider_test.go)
• New CLI command → Must include command tests (*_test.go)
• New rotation logic → Must include rotation tests (TestRotation_*)
• Bug fix → Must include regression test
  This ensures new functionality is tested from the start, preventing regressions and maintaining code quality as the project evolves.

Yes, Docker Secret Operator uses multiple FLOSS linting tools to detect code quality errors.

Linter tools used:

1. go vet (built-in, FLOSS) - Detects suspicious code patterns
2. go test -race (built-in, FLOSS) - Detects race conditions
3. staticcheck (FLOSS) - Advanced static analysis

Invocation:

• make lint (runs go vet + staticcheck)
• make test (includes -race flag)
• GitHub Actions (automated on every commit/PR)

Configuration: .github/workflows/coverage.yml

This catches:

• Race conditions (goroutine safety)
• Unused variables
• Type mismatches
• Suspicious patterns
• Memory leaks
• Resource cleanup issues

All tools are open source with no proprietary dependencies.

Yes, Docker Secret Operator addresses all linter warnings.

Process:

• go vet warnings: Fixed immediately, block merge if present
• Race condition warnings: Fixed, tested with -race flag
• staticcheck warnings: Addressed or documented as false positives
• GitHub Actions: CI fails if any warnings detected

Evidence from Phase 1 (May 2026):

• Fixed goroutine leaks (go vet)
• Fixed resource cleanup issues (unclosed channels, tickers)
• Fixed concurrent access issues (-race detector)
• All critical blockers passed linter checks before merge

Current status: Zero outstanding linter warnings in main branch

Yes, Docker Secret Operator enforces strict warning settings.

Strictness measures:

• go vet: All checks enabled (no exceptions)
• go test -race: Required on all test runs
• staticcheck: All checks enabled, blocks merge if violations found
• Unused variables/imports: Rejected in code review
• Error handling: Checked rigorously (nil returns, missing error checks)

Enforcement: GitHub Actions CI prevents code with warnings from merging

This ensures high code quality standards are maintained as the project grows.

   • Mitigation: Lock manager with fail-fast design, -race testing
   • Evidence: Phase 1 fix - lock manager initialization, concurrent test cases

3. Resource Exhaustion (Goroutine Leaks)

   • Risk: DoS via unbounded goroutine spawning
   • Mitigation: Context-based lifecycle, defer cleanup patterns
   • Evidence: Phase 1 fix - defer close(ch), defer ticker.Stop()

4. Privilege Escalation

   • Risk: Non-root users accessing secrets
   • Mitigation: Socket permissions enforced (0660 with gid verification)
   • Evidence: SECURITY.md socket security section, permission checks

5. Denial of Service (Hangs)

   • Risk: Indefinite hangs on I/O operations
   • Mitigation: 30-second context timeouts on critical operations
   • Evidence: Phase 1 fix - resolver timeout, proxy scan timeout

6. File Descriptor Leaks

   • Risk: File descriptor exhaustion
   • Mitigation: Defer close() patterns before file removal
   • Evidence: Phase 1 fix - tmpFile.Close() in up.go

7. Provider Failures

   • Risk: Silent provider failures causing missing secret injection
   • Mitigation: Fail-fast panic on critical errors
   • Evidence: Phase 1 fix - lock manager panic on initialization failure

All mitigations implemented and tested in production code.
