Overview

The release system follows modern DevOps practices with:

Intent-Driven Configuration: YAML-based release configuration with schema validation
Multi-Target Deployment: Python packages (PyPI), Docker images (dual registry), and documentation (Docusaurus)
Supply Chain Security: SBOM generation, vulnerability scanning, cosign signing, and SLSA attestation
Comprehensive Validation: Pre-release validation without publishing artifacts
Staging Environment: Safe testing environment with TestPyPI and staging tags
Git Synchronization: Fixed critical version sync issues ensuring artifacts use correct bumped versions

Release Workflows

1. Production Release Workflow (`release.yml`)

Purpose: Production releases to PyPI, Docker registries, and documentation deployment

Triggers:

Push to master branch
Manual dispatch (workflow_dispatch)

Enhanced Config-Based Architecture:

Enhanced Workflow Steps

The production release workflow now includes an enhanced config-based flow with the following steps:

Step 1: Configuration Parsing

config:
  name: Parse Configuration
  uses: Chisanan232/Template-Python-UV-Project/.github/workflows/rw_parse_project_config.yaml@master

Parses enhanced intent.yaml with project, docker, git, validation, and docs configuration
Provides structured outputs for all downstream jobs
Auto-detects project name and package name from repository and pyproject.toml
Applies smart defaults for missing configuration sections

Step 2: Release Intent Analysis

intent:
  uses: Chisanan232/Template-Python-UV-Project/.github/workflows/rw_parse_release_intent.yaml@master
  needs: config

Validates release intent against enhanced JSON schema
Compatible with both legacy and enhanced configuration formats
Determines release artifacts (python, docker, docs) based on configuration

Multi-Target Deployments

Python Package (PyPI) - Config Enhanced:
- Uses uv build and uv publish
- OIDC Trusted Publishers for secure authentication
- Config Integration: Uses ${{ needs.config.outputs.package_name }} for package identification
- Git Configuration: Commits using ${{ needs.config.outputs.git_commit_name }} and ${{ needs.config.outputs.git_commit_email }}
- Fixed: Automatic version synchronization with git sync fix
- Enhanced: uv.lock file automatically updated and committed with version bumps
- Builds from correct bumped version (e.g., 0.0.1, not 0.0.0)
Docker Image (GHCR & DockerHub) - Config Enhanced:
- Config-Based Registry URLs:
  - Docker Hub: Uses ${{ needs.config.outputs.docker_registry_dockerhub }}
  - GHCR: Uses ${{ needs.config.outputs.docker_registry_ghcr }}
- Health Check Configuration: Uses config-based ${{ needs.config.outputs.docker_health_check_path }} and ${{ needs.config.outputs.docker_health_check_port }}
- Application Environment: Uses ${{ needs.config.outputs.docker_app_env_name }} and ${{ needs.config.outputs.docker_app_env_value }}
- Dual Registry Publishing: Publishes to both registries simultaneously
- Parallel Publishing Jobs: Separate jobs ensure isolated registry operations
- Multi-architecture builds: amd64, arm64 support for both registries
- Supply Chain Security: SBOM generation, Cosign signing, SLSA attestation
- Registry-Specific Authentication: GHCR uses GitHub token, Docker Hub uses dedicated credentials
- Consistent Tagging: Same version tags applied to both registries
- Fixed: Uses correct version tags from git sync fix
Documentation (Docusaurus) - Config Enhanced:
- Config-Based Documentation Paths: Uses structured config outputs:
  - README Path: ${{ needs.config.outputs.docs_readme_path }}
  - Installation Guide: ${{ needs.config.outputs.docs_installation_path }}
  - CI/CD Documentation: ${{ needs.config.outputs.docs_ci_cd_path }}
- Preview Branch Configuration: Uses ${{ needs.config.outputs.docs_preview_branch }} for staging documentation
- Enhanced Configuration Support: Works with both legacy string format and new object format:
```
# Enhanced format (from config)
docs:
  mode: "auto"
  sections: ["docs", "dev"]
  strategy: "changed"
```
- Intelligent Documentation Triggering: Uses DOCS_UPDATED flag to automatically trigger documentation deployment
- Version Reference Updates: Automatically updates documentation files that reference the package version
- Workflow Run Pattern: Triggers documentation workflow via workflow_run to overcome GITHUB_TOKEN limitations
- Multi-section versioning support: Independent versioning for docs, dev, and api sections
- Change detection: Selective updates based on actual file changes
- Matrix-based concurrent processing: Efficient parallel versioning
- Fixed: Versions using correct bumped version from git sync fix

2. Release Validation Workflow (`release-validate.yml`)

Purpose: Pre-release validation without publishing artifacts

Triggers:

Pull requests to master
Manual dispatch

Enhanced Config-Based Validation Steps:

Step-by-Step Enhanced Validation:

Step 1: Configuration Parsing & Validation

config:
  name: Parse Configuration
  uses: Chisanan232/Template-Python-UV-Project/.github/workflows/rw_parse_project_config.yaml@master

Validates enhanced intent.yaml structure and syntax
Tests config output generation for all sections (project, docker, git, validation, docs)
Verifies auto-detection logic for project and package names
Validates Docker registry URLs and health check configurations
Confirms documentation path accessibility

Step 2: Release Intent Validation

intent-parse:
  uses: Chisanan232/Template-Python-UV-Project/.github/workflows/rw_parse_release_intent.yaml@master
  needs: config

Enhanced JSON schema validation supporting both legacy and new config formats
Validates release intent against config-provided defaults
Tests artifact configuration (python, docker, docs) with enhanced format support

Enhanced Security Validation

Defensive Checks: Pre-flight image existence validation
Vulnerability Scanning: Grype integration for CVE detection
Fallback SBOM: Workspace scanning if Docker image scan fails
Supply Chain Security: Full SBOM, signing, and attestation testing

3. Staging Release Workflow (`release-staging.yml`)

Purpose: Deploy to staging environments for testing with enhanced config-based customization

Triggers:

Manual dispatch only (workflow_dispatch)

Enhanced Config-Based Staging Architecture:

Enhanced Staging Steps:

Step 1: Configuration Parsing

config:
  name: Parse Configuration
  uses: Chisanan232/Template-Python-UV-Project/.github/workflows/rw_parse_project_config.yaml@master

Loads staging-specific configuration from enhanced intent.yaml
Provides validation version settings: ${{ needs.config.outputs.validation_version }} and ${{ needs.config.outputs.validation_test_version }}
Configures preview documentation branch: ${{ needs.config.outputs.docs_preview_branch }}

Step 2: Staging Version Computation

Uses config-based validation version format
Creates release candidate versions with config-provided settings
Integrates with git configuration from config outputs

Config-Enhanced Staging Targets:

TestPyPI - Config Enhanced:
- Pre-release Python packages using ${{ needs.config.outputs.validation_version }}
- Git commits with ${{ needs.config.outputs.git_commit_name }} and ${{ needs.config.outputs.git_commit_email }}
GHCR Staging - Config Enhanced:
- Docker images with -rc tags using ${{ needs.config.outputs.docker_registry_ghcr }}
- Health check validation using config-based ${{ needs.config.outputs.docker_health_check_path }} and ${{ needs.config.outputs.docker_health_check_port }}
- Application environment testing with ${{ needs.config.outputs.docker_app_env_name }} and ${{ needs.config.outputs.docker_app_env_value }}
Documentation Preview - Config Enhanced:
- Staging documentation branch using ${{ needs.config.outputs.docs_preview_branch }}
- Documentation paths from config: README, installation, and CI/CD documentation
- Version testing using ${{ needs.config.outputs.validation_test_version }}

Enhanced Staging Validation Process

Config-Based RC Version Generation: Creates release candidate versions using validation settings from config
Multi-Environment Testing: Tests all config-provided registry URLs and settings
Preview Environment: Safe testing environment with customizable branch names
Configuration Validation: Validates that all config outputs work in staging environment

Multi-Section Documentation Versioning

The release system supports advanced documentation versioning:

Features

Section-Based Versioning: Independent versioning for docs, dev, and api sections
Change Detection: Automatic detection of changes per section
Strategy Control: Version all sections or only changed sections
Matrix Processing: Concurrent versioning for performance

Configuration Examples

# Legacy format (backward compatible)
docs: "auto"

# Enhanced format
docs:
  mode: "auto"
  sections: ["docs", "dev"]
  strategy: "changed"  # Only version changed sections

Supply Chain Security

All release workflows include comprehensive supply chain security:

Security Features

SBOM Generation: Software Bill of Materials with Syft
Vulnerability Scanning: CVE detection with Grype
Digital Signing: Cosign keyless signing
Attestation: SLSA provenance attestation
Defensive Programming: Pre-flight checks and clear error messages

Enhanced Configuration System (New)

Overview

The template now features a comprehensive config-based system that extends beyond release intent to provide centralized project configuration management. This eliminates scattered environment variables and provides a single source of truth for all project settings.

Architecture

Enhanced Configuration Structure

The enhanced intent.yaml now includes comprehensive project settings:

# === RELEASE INTENT (Original) ===
release: true
level: "patch"
artifacts:
  python: "auto"
  docker: "auto" 
  docs:
    mode: "auto"
    sections: ["docs", "dev"]
    strategy: "always"
notes: "Enhanced release with comprehensive configuration"

# === PROJECT CONFIGURATION (New) ===
project:
  name: null                    # Auto-detected from repository
  package_name: null           # Auto-detected from pyproject.toml
  base_branch: "master"        # Default branch for operations

git:
  commit:
    name: "GitHub Actions Bot"
    email: "actions@github.com"

docker:
  registries:
    dockerhub: "docker.io"
    ghcr: "ghcr.io"
  health_check:
    path: "/health"
    port: 8000
  application:
    env_var_name: "API_TOKEN"
    env_var_value: "test_token"

validation:
  version: "1.0.0-validation"
  test_version: "validation-test"

docs:
  paths:
    readme: "README.md"
    installation: "docs/INSTALLATION.md"
    ci_cd: "docs/CI_CD.md"
  preview:
    branch: "docs-preview"

Configuration Parser Workflow

The new rw_parse_project_config.yaml reusable workflow centralizes configuration parsing:

# Called by all release workflows
config:
  name: Parse Configuration
  uses: Chisanan232/Template-Python-UV-Project/.github/workflows/rw_parse_project_config.yaml@master

# Other jobs reference config outputs
other-job:
  needs: config
  steps:
    - name: Use config values
      env:
        PROJECT_NAME: ${{ needs.config.outputs.project_name }}
        BASE_BRANCH: ${{ needs.config.outputs.base_branch }}
        DOCKER_REGISTRY: ${{ needs.config.outputs.docker_registry_dockerhub }}

Configuration Outputs

The parser provides structured outputs for all workflows:

Project Configuration

project_name: Project name (auto-detected)
package_name: Python package name (auto-detected)
base_branch: Default branch for operations

Git Configuration

git_commit_name: Git commit author name
git_commit_email: Git commit author email

Docker Configuration

docker_registry_dockerhub: Docker Hub registry URL
docker_registry_ghcr: GitHub Container Registry URL
docker_health_check_path: Health check endpoint
docker_health_check_port: Health check port
docker_app_env_name: Application environment variable name
docker_app_env_value: Application environment variable value

Validation Configuration

validation_version: Version for validation workflows
validation_test_version: Test version identifier

Documentation Configuration

docs_readme_path: README file path
docs_installation_path: Installation documentation path
docs_ci_cd_path: CI/CD documentation path
docs_preview_branch: Documentation preview branch

Benefits of Config-Based System

✅ Centralized Management: Single source of truth in intent.yaml
✅ Smart Defaults: Works without configuration file
✅ Self-Documenting: Clear structure and validation
✅ Backward Compatible: Maintains existing release intent functionality
✅ Easy Customization: Child projects edit one file
✅ Type Safety: JSON schema validation for all configuration
✅ External References: Uses template repository for reusable workflows

Migration from Environment Variables

Before (Scattered Variables):

# Multiple places with hardcoded values
env:
  DOCKER_REGISTRY: "docker.io"
  GIT_EMAIL: "actions@github.com" 
  BASE_BRANCH: "master"
  # ... scattered across multiple files

After (Centralized Configuration):

# Single intent.yaml configuration
docker:
  registries:
    dockerhub: "docker.io"
git:
  commit:
    email: "actions@github.com"
project:
  base_branch: "master"

Usage in Child Projects

Child projects customize by editing intent.yaml sections:

# Customize for your project
project:
  base_branch: "main"           # Use main instead of master

docker:
  registries:
    dockerhub: "myregistry.io"  # Use custom registry
  health_check:
    port: 3000                  # Custom port

git:
  commit:
    name: "My Bot"              # Custom commit author
    email: "bot@mycompany.com"

docs:
  preview:
    branch: "preview"           # Custom preview branch

All workflows automatically use these customized values via the config parsing system.

Technical Implementation Details

Schema Compatibility

The enhanced system maintains full backward compatibility with existing release intent configurations:

{
  "title": "Release Intent and Project Configuration",
  "description": "Validates release intent core properties while allowing additional project configuration sections",
  "additionalProperties": true,  // Allows new config sections
  // ... release intent validation unchanged
}

Workflow Dependencies

All enhanced workflows follow a consistent dependency pattern:

jobs:
  # Step 1: Parse configuration (always first)
  config:
    name: Parse Configuration  
    uses: Chisanan232/Template-Python-UV-Project/.github/workflows/rw_parse_project_config.yaml@master

  # Step 2: Parse release intent (depends on config)
  intent:
    uses: Chisanan232/Template-Python-UV-Project/.github/workflows/rw_parse_release_intent.yaml@master
    needs: config

  # Step 3: All other jobs depend on both
  other-jobs:
    needs: [config, intent]
    env:
      PROJECT_NAME: ${{ needs.config.outputs.project_name }}
      RELEASE_ENABLED: ${{ needs.intent.outputs.release }}

Auto-Detection Logic

The config parser includes intelligent auto-detection:

# Auto-detection with fallbacks
project_name: ${{ github.event.repository.name || 'auto-detected' }}
package_name: # Extracted from pyproject.toml [project.name] 
base_branch: ${{ config.project.base_branch || 'master' }}

Migration Guide for Child Projects

Step 1: Update intent.yaml (Optional)

Child projects can optionally enhance their intent.yaml with project-specific configuration:

# Minimal - uses all defaults (works unchanged)
release: true
level: auto
artifacts:
  python: auto
  docker: auto
  docs: auto

# Enhanced - customize for your project
project:
  base_branch: "main"      # If you use 'main' instead of 'master'
  
docker:
  registries:
    dockerhub: "myorg"     # Your Docker Hub organization
  health_check:
    port: 3000             # Your application port
    
git:
  commit:
    name: "Deploy Bot"     # Your preferred commit author
    email: "deploy@yourcompany.com"

docs:
  preview:
    branch: "docs-staging" # Your docs preview branch

Step 2: Verify External Workflow References

Ensure your workflows reference the template repository:

# ✅ Correct - External repository reference
uses: Chisanan232/Template-Python-UV-Project/.github/workflows/rw_parse_project_config.yaml@master

# ❌ Incorrect - Local reference (won't work in child projects)  
uses: ./.github/workflows/rw_parse_project_config.yaml

Step 3: Update Custom Workflows (If Any)

If you have custom workflows that need config values:

jobs:
  config:
    uses: Chisanan232/Template-Python-UV-Project/.github/workflows/rw_parse_project_config.yaml@master
    
  my-custom-job:
    needs: config
    runs-on: ubuntu-latest
    steps:
      - name: Use config values
        env:
          DOCKER_REGISTRY: ${{ needs.config.outputs.docker_registry_dockerhub }}
          BASE_BRANCH: ${{ needs.config.outputs.base_branch }}
          GIT_EMAIL: ${{ needs.config.outputs.git_commit_email }}
        run: |
          echo "Using registry: $DOCKER_REGISTRY"
          echo "Base branch: $BASE_BRANCH"  
          echo "Git email: $GIT_EMAIL"

Compatibility Matrix

Template Version	Child Project Action	Compatibility	Notes
Enhanced	No changes	✅ Full	Uses smart defaults
Enhanced	Add project config	✅ Full	Uses custom values
Enhanced	Old intent.yaml only	✅ Full	Backward compatible
Legacy	Enhanced intent.yaml	⚠️ Partial	Config ignored, no errors

Best Practices

1. Configuration Management

✅ Recommended Approach:

# Use smart defaults, customize only what you need
project:
  base_branch: "main"          # Only if different from 'master'
  
docker:
  registries:
    dockerhub: "myorganization" # Only if different from auto-detected

❌ Avoid Over-Configuration:

# Don't set values that match defaults
project:
  name: "my-project"          # Auto-detected from repository
  package_name: "my_project"  # Auto-detected from pyproject.toml

2. Workflow Dependencies

✅ Always Use Config Dependency:

jobs:
  config:
    uses: Chisanan232/Template-Python-UV-Project/.github/workflows/rw_parse_project_config.yaml@master
    
  my-job:
    needs: config  # Always depend on config

3. External References

✅ Pin to Stable Versions:

# Production workflows - use stable tags
uses: Chisanan232/Template-Python-UV-Project/.github/workflows/rw_parse_project_config.yaml@v1.0.0

# Development - can use master  
uses: Chisanan232/Template-Python-UV-Project/.github/workflows/rw_parse_project_config.yaml@master

4. Testing Configuration Changes

Validation Workflow:

# Test configuration parsing
gh workflow run release-validate.yml

# Check config outputs
gh run list --workflow=release-validate.yml --limit=1
gh run view <run-id> --log

Troubleshooting

Common Issues

1. Configuration Not Taking Effect

Symptom: Workflows use default values despite custom config
Solution: Ensure workflows reference needs.config.outputs.*
Check: Verify config job runs before dependent jobs

2. External Workflow Not Found

Symptom: workflow not found error in GitHub Actions
Solution: Ensure external repository reference includes @master or version tag
Check: Verify repository access permissions

3. Schema Validation Errors

Symptom: Release intent parsing fails with validation error
Solution: Check configuration syntax against schema
Check: Use JSON schema validator for syntax verification

Debug Configuration

View Parsed Configuration:

# Add debug step to any workflow
- name: Debug Configuration
  env:
    CONFIG_OUTPUTS: ${{ toJson(needs.config.outputs) }}
  run: |
    echo "=== PARSED CONFIGURATION ==="
    echo "$CONFIG_OUTPUTS" | jq '.'

Test Configuration Parsing:

# Run release intent script locally
uv run python scripts/ci/release_intent.py

# Validates schema and shows full parsed config

Enhanced Release Intent & Project Configuration Reference

The .github/tag_and_release/intent.yaml file is now the central configuration hub for both release behavior and comprehensive project settings. This enhanced system eliminates scattered environment variables and provides a single source of truth for all project configuration.

How Enhanced Configuration Works

The enhanced system follows this two-step parsing process:

Configuration Parsing (rw_parse_project_config.yaml):
- Loads and validates the complete intent.yaml structure
- Provides structured outputs for project, git, docker, validation, and docs settings
- Applies smart defaults for missing configuration sections
- Auto-detects project and package names
Release Intent Analysis (rw_parse_release_intent.yaml):
- Focuses on release-specific logic (release, level, artifacts, notes)
- Compatible with both legacy and enhanced configuration formats
- Uses configuration parser outputs for enhanced validation

Configuration Options

Release Intent Configuration (Core)

These are the core release control options that determine release behavior:

1. Master Release Control

release (boolean, default: true)

true: Enable release processing with config-enhanced workflows
false: Skip all release operations

# Enable releases with enhanced config system
release: true

# Disable releases entirely
release: false

2. Version Bump Level

level (string, default: "auto") Controls semantic version bumping with config-enhanced git operations:

"auto": Determine version bump automatically based on commit messages
"patch": Force patch version bump (e.g., 1.0.0 → 1.0.1)
"minor": Force minor version bump (e.g., 1.0.0 → 1.1.0)
"major": Force major version bump (e.g., 1.0.0 → 2.0.0)

# Automatic version detection - uses config-based git settings
level: auto

# Force specific version bumps - commits use enhanced git configuration
level: patch  # 1.0.0 → 1.0.1 (commits with config.outputs.git_commit_name)
level: minor  # 1.0.0 → 1.1.0 (commits with config.outputs.git_commit_email)
level: major  # 1.0.0 → 2.0.0 (commits with config-enhanced settings)

Enhanced Project Configuration (New)

These are the new project-level configuration sections that provide centralized management:

6. Project Configuration

project (object) Defines project identification and base settings:

project:
  name: null                    # string | null - Auto-detected from repository name
  package_name: null           # string | null - Auto-detected from pyproject.toml
  base_branch: "master"        # string - Default branch for workflow operations

Configuration Options:

name: Project name (auto-detected from ${{ github.event.repository.name }})
package_name: Python package name (extracted from pyproject.toml [project.name])
base_branch: Default branch for git operations and branch references

Usage in Workflows:

# Workflows use these via config outputs:
PROJECT_NAME: ${{ needs.config.outputs.project_name }}
PACKAGE_NAME: ${{ needs.config.outputs.package_name }}
BASE_BRANCH: ${{ needs.config.outputs.base_branch }}

7. Git Configuration

git (object) Configures git commit settings for automated operations:

git:
  commit:
    name: "GitHub Actions Bot"   # string - Git commit author name
    email: "actions@github.com"  # string - Git commit author email

Configuration Options:

commit.name: Author name for automated commits (version bumps, documentation updates)
commit.email: Author email for automated commits

Usage in Workflows:

# All version bump and automated commit operations use:
GIT_COMMIT_NAME: ${{ needs.config.outputs.git_commit_name }}
GIT_COMMIT_EMAIL: ${{ needs.config.outputs.git_commit_email }}

# Example: Version bump commits
- name: Configure Git
  run: |
    git config user.name "${{ needs.config.outputs.git_commit_name }}"
    git config user.email "${{ needs.config.outputs.git_commit_email }}"

8. Docker Configuration

docker (object) Comprehensive Docker deployment configuration:

docker:
  registries:
    dockerhub: "docker.io"       # string - Docker Hub registry URL
    ghcr: "ghcr.io"             # string - GitHub Container Registry URL
  health_check:
    path: "/health"              # string - Health check endpoint
    port: 8000                   # number - Health check port
  run_options: "-e API_TOKEN=test_token -e DEBUG=true -v /host/data:/app/data --network mynetwork"

Configuration Options:

registries.dockerhub: Docker Hub registry URL for dual publishing
registries.ghcr: GitHub Container Registry URL for dual publishing
health_check.path: HTTP health check endpoint path
health_check.port: Port for health check operations
run_options: Flexible string for Docker run options (environment variables, volumes, networks, etc.)

Advanced Docker Run Options Examples:

# Basic environment variables
docker:
  run_options: "-e API_TOKEN=test_token -e DEBUG=true"

# Multiple environment variables with volumes
docker:
  run_options: "-e API_TOKEN=test_token -e DB_URL=postgresql://localhost:5432/app -v /host/data:/app/data -v /host/logs:/app/logs"

# Complex configuration with network and resource limits
docker:
  run_options: "-e API_TOKEN=test_token -e REDIS_URL=redis://localhost:6379 --network mynetwork --memory=512m --cpus=0.5 -v /host/config:/app/config:ro"

# Production-ready configuration
docker:
  run_options: "-e NODE_ENV=production -e API_TOKEN=prod_token -e DB_URL=postgresql://prod-db:5432/app -e REDIS_URL=redis://prod-redis:6379 --network prod-network --restart unless-stopped -v /data/app:/app/data -v /logs/app:/app/logs"

Usage in Workflows:

# Docker build and publish operations use:
DOCKERHUB_REGISTRY: ${{ needs.config.outputs.docker_registry_dockerhub }}
GHCR_REGISTRY: ${{ needs.config.outputs.docker_registry_ghcr }}
HEALTH_CHECK_PATH: ${{ needs.config.outputs.docker_health_check_path }}
HEALTH_CHECK_PORT: ${{ needs.config.outputs.docker_health_check_port }}
DOCKER_RUN_OPTIONS: ${{ needs.config.outputs.docker_run_options }}

# Example: Using the flexible Docker run options in workflows
jobs:
  docker-operations:
    uses: Chisanan232/Template-Python-UV-Project/.github/workflows/rw_docker_operations.yaml@master
    needs: config
    with:
      operation: 'push'
      registry: ${{ needs.config.outputs.docker_registry_dockerhub }}
      version: '1.0.0'
      docker-run-options: ${{ needs.config.outputs.docker_run_options }}

# Example: Health check validation
- name: Test Health Check
  run: |
    curl -f "http://localhost:${{ needs.config.outputs.docker_health_check_port }}${{ needs.config.outputs.docker_health_check_path }}"

Benefits of Flexible Docker Run Options:

Multiple Environment Variables: Pass any number of environment variables in a single string
Volume Mounts: Configure data persistence and file sharing between host and container
Network Configuration: Specify custom Docker networks for container connectivity
Resource Limits: Set memory and CPU constraints for container resource management
Runtime Options: Configure restart policies, security contexts, and other Docker runtime settings
Child Project Flexibility: Each project using the template can customize Docker behavior without modifying workflows

9. Validation Configuration

validation (object) Settings for validation and staging workflows:

validation:
  version: "1.0.0-validation"    # string - Version for validation workflows
  test_version: "validation-test" # string - Test version identifier

Configuration Options:

version: Version identifier used in validation and staging workflows
test_version: Test version identifier for staging operations

Usage in Workflows:

# Validation and staging workflows use:
VALIDATION_VERSION: ${{ needs.config.outputs.validation_version }}
TEST_VERSION: ${{ needs.config.outputs.validation_test_version }}

# Example: Staging deployment
- name: Deploy to TestPyPI
  env:
    VERSION: ${{ needs.config.outputs.validation_version }}
  run: |
    uv publish --repository testpypi

10. Documentation Configuration

docs (object) Documentation paths and preview settings:

docs:
  paths:
    readme: "README.md"          # string - README file path
    installation: "docs/INSTALLATION.md" # string - Installation guide path
    ci_cd: "docs/CI_CD.md"      # string - CI/CD documentation path
  preview:
    branch: "docs-preview"       # string - Preview branch name

Configuration Options:

paths.readme: Path to README file for version reference updates
paths.installation: Path to installation documentation
paths.ci_cd: Path to CI/CD documentation
preview.branch: Branch name for documentation preview/staging

Usage in Workflows:

# Documentation workflows use:
README_PATH: ${{ needs.config.outputs.docs_readme_path }}
INSTALLATION_PATH: ${{ needs.config.outputs.docs_installation_path }}
CICD_PATH: ${{ needs.config.outputs.docs_ci_cd_path }}
PREVIEW_BRANCH: ${{ needs.config.outputs.docs_preview_branch }}

# Example: Update version references
- name: Update Documentation Version References
  run: |
    sed -i "s/version: .*/version: $NEW_VERSION/" "${{ needs.config.outputs.docs_readme_path }}"

3. Python Package Configuration

artifacts.python (string, default: "auto") Controls Python package publishing to PyPI with dual authentication support:

"auto": Publish if package files changed
"force": Always publish regardless of changes
"skip": Skip Python package publishing

artifacts:
  # Conditional publishing (recommended)
  python: auto
  
  # Always publish
  python: force
  
  # Skip publishing
  python: skip

PyPI Authentication Methods

The template now supports dual authentication methods for PyPI package uploads, providing both modern security and backward compatibility:

Authentication Configuration:

# Enhanced project configuration (New)
python:
  auth_method: "oidc"  # or "token"

OIDC Authentication (Recommended) 🔒

Benefits:

✅ Keyless Authentication: No API tokens to manage or rotate
✅ Enhanced Security: Uses GitHub's OIDC identity tokens
✅ Zero Secrets: No repository secrets needed
✅ PyPI Recommended: Official PyPI recommendation for CI/CD

Setup Requirements:

Configure Trusted Publisher on PyPI:
- Go to PyPI → Account Settings → Publishing
- Add GitHub as trusted publisher
- Repository: your-org/your-repo
- Workflow: release.yml (or your release workflow name)
- Environment: production (optional)
Set Authentication Method:

# In .github/tag_and_release/intent.yaml
python:
  auth_method: "oidc"  # Default, recommended

No Additional Setup: OIDC works automatically! ✨

How OIDC Works:

Token Authentication (Legacy) 🔑

Benefits:

✅ Backward Compatible: Works with existing PyPI token setups
✅ Universal Support: Works with all PyPI-compatible repositories
✅ Simple Migration: Easy transition from existing token-based workflows

Setup Requirements:

Generate API Tokens:
- Production: PyPI Account Settings → Create new token
- Staging: TestPyPI Account Settings → Create new token
Add Repository Secrets:
- PYPI_API_TOKEN: Your production PyPI API token
- TEST_PYPI_API_TOKEN: Your TestPyPI API token
Configure Authentication Method:

# In .github/tag_and_release/intent.yaml
python:
  auth_method: "token"

Security Considerations:

🔄 Token Rotation: Regularly rotate API tokens
🔒 Secret Management: Store tokens securely in GitHub repository secrets
🎯 Scope Limitation: Use project-scoped tokens when possible

Authentication Configuration Examples

Example 1: OIDC Authentication (Recommended)

# Modern, secure, keyless authentication
python:
  auth_method: "oidc"

artifacts:
  python: "auto"

# No secrets needed - uses GitHub OIDC identity

Example 2: Token Authentication (Legacy)

# Traditional API token authentication
python:
  auth_method: "token"

artifacts:
  python: "auto"

# Requires repository secrets:
# - PYPI_API_TOKEN
# - TEST_PYPI_API_TOKEN

Example 3: Mixed Environment Strategy

# Development projects can use OIDC for simplicity
# Production projects might prefer token control
python:
  auth_method: "oidc"  # Easy setup for development

artifacts:
  python: "auto"

Authentication Method Comparison

Feature	OIDC Authentication	Token Authentication
Security	🟢 Keyless, identity-based	🟡 Token-based, requires rotation
Setup Complexity	🟢 Simple (just configure trusted publisher)	🟡 Moderate (generate + store tokens)
Maintenance	🟢 Zero maintenance	🟡 Regular token rotation needed
PyPI Support	🟢 Official recommendation	🟢 Universal support
Secrets Required	🟢 None	🔴 2 secrets (PYPI + TEST_PYPI tokens)
Backward Compatibility	🟡 Modern PyPI feature	🟢 Works everywhere
Troubleshooting	🟢 Clear OIDC validation errors	🟡 Token validation complexity

Authentication Workflow Architecture

The dual authentication system seamlessly integrates with the existing release architecture:

Implementation Details:

Centralized Configuration: Authentication method specified once in intent.yaml
Secret Forwarding: Proper secret passing from calling workflows to reusable workflows
Conditional Logic: Workflows automatically select authentication method
Error Handling: Clear validation and error messages for missing tokens
Operation Summary: Workflow reports which authentication method was used

Migration Guide

From Token to OIDC (Recommended):

Set up PyPI Trusted Publisher for your repository

Update intent.yaml:

python:
  auth_method: "oidc"  # Change from "token"

Test with staging release workflow
Optionally remove PyPI token secrets (but keep for rollback)

From OIDC to Token (if needed):

Generate PyPI API tokens
Add PYPI_API_TOKEN and TEST_PYPI_API_TOKEN to repository secrets

Update intent.yaml:

python:
  auth_method: "token"  # Change from "oidc"

Test with staging release workflow

Troubleshooting Authentication

OIDC Authentication Issues:

Error: OIDC token validation failed
Solution: Verify PyPI Trusted Publisher configuration matches your repository and workflow
Check: Repository name, workflow filename, and optional environment name

Token Authentication Issues:

Error: PyPI API token not found in secrets
Solution: Verify PYPI_API_TOKEN and TEST_PYPI_API_TOKEN are added to repository secrets
Check: Token scope and expiration date

General Authentication Debugging:

Workflow Logs: Check the Python package workflow step for detailed authentication logs
Operation Summary: Each workflow reports which authentication method was used
Validation Workflow: Test authentication setup with release-validate.yml

4. Docker Image Configuration

artifacts.docker (string, default: "auto") Controls Docker image publishing to both Docker Hub and GitHub Container Registry (GHCR):

"auto": Publish if Docker-related files changed (Dockerfile, scripts, etc.)
"force": Always publish to both registries regardless of changes
"skip": Skip Docker image publishing to both registries

artifacts:
  # Conditional publishing (recommended)
  docker: auto    # Publishes to both registries if Docker files changed
  
  # Always publish
  docker: force   # Always publishes to both registries
  
  # Skip publishing
  docker: skip    # Skips both registries

Dual Registry Publishing Details

When docker: auto or docker: force, the workflow creates two parallel jobs:

Docker Hub Job (release_docker_dockerhub):
- Registry: docker.io
- Image: chisanan232/test-python-uv-project-template:VERSION
- Authentication: DockerHub credentials (DOCKERHUB_USERNAME, DOCKERHUB_TOKEN)
GHCR Job (release_docker_ghcr):
- Registry: ghcr.io
- Image: ghcr.io/chisanan232/test-python-uv-project-template:VERSION
- Authentication: GitHub token (GITHUB_TOKEN)

Both jobs run simultaneously and produce identical images with the same version tags.

5. Documentation Configuration

artifacts.docs (object | string) Controls documentation versioning with support for both legacy and enhanced formats.

Legacy Format (String)

artifacts:
  docs: "auto"  # auto, force, skip

Enhanced Format (Object)

artifacts:
  docs:
    mode: "auto"              # auto, force, skip
    sections: ["docs", "dev"]  # array of section names
    strategy: "changed"       # changed, always

Configuration Options:

docs.mode (string, default: "auto")

"auto": Version docs based on strategy and change detection
"force": Always version docs regardless of changes or strategy
"skip": Skip documentation versioning entirely

docs.sections (array, default: ["docs", "dev"]) Array of Docusaurus plugin IDs to version:

"docs": Main user documentation
"dev": Development/contributor documentation
"api": API reference documentation

docs.strategy (string, default: "changed")

"changed": Only version sections that have file changes
"always": Version all configured sections regardless of changes

Configuration Examples

Example 1: Conservative Release (Recommended)

# Only release what has actually changed
release: true
level: auto
artifacts:
  python: auto
  docker: auto
  docs:
    mode: auto
    sections: ["docs", "dev"]
    strategy: changed
notes: "Automatic release with change detection"

Example 2: Force Full Release

# Force release all artifacts regardless of changes
release: true
level: patch
artifacts:
  python: force
  docker: force
  docs:
    mode: force
    sections: ["docs", "dev", "api"]
    strategy: always
notes: "Full release of all components"

Example 3: Selective Release

# Only release Python package, skip others
release: true
level: minor
artifacts:
  python: force
  docker: skip
  docs: skip
notes: "Python package only release"

Example 4: Documentation-Only Release

# Only version documentation
release: true
level: patch
artifacts:
  python: skip
  docker: skip
  docs:
    mode: force
    sections: ["docs", "dev"]
    strategy: always
notes: "Documentation update release"

Behavioral Matrix

Configuration	Changed Files	Behavior
`python: auto`	Python files changed	✅ Publishes to PyPI
`python: auto`	No Python files changed	⏭️ Skips publishing
`python: force`	Any/no changes	✅ Always publishes
`python: skip`	Any/no changes	⏭️ Always skips
`docs.mode: auto, strategy: changed`	Docs files changed	✅ Versions changed sections
`docs.mode: auto, strategy: always`	Any changes	✅ Versions all sections
`docs.mode: force`	Any/no changes	✅ Always versions

Configuration Validation

The release intent parser includes JSON schema validation to ensure configuration correctness:

Invalid Options: Unsupported values are rejected with clear error messages
Type Checking: Ensures correct data types for all fields
Required Fields: Validates that essential configuration is present
Default Values: Applies sensible defaults for missing optional fields

Example Validation Errors:

# ❌ Invalid configuration
level: invalid_level        # Error: Must be auto, patch, minor, or major
artifacts:
  docs:
    strategy: invalid       # Error: Must be changed or always
    sections: "not-array"   # Error: Must be array of strings

Developer Guide

Using the Release System

1. Configuring a Release

Edit .github/tag_and_release/intent.yaml to configure your release:

# Example: Patch release with selective docs versioning
version_bump: "patch"
python: "auto"
docker: "auto"
docs:
  mode: "auto"
  sections: ["docs", "dev"]  # Only version docs and dev sections
  strategy: "changed"        # Only version if changes detected
github_release: "auto"

2. Triggering Releases

Automatic Release (Push to master):

git push origin master
# Triggers release workflow automatically

Manual Release (GitHub UI):

Go to Actions → Release
Click "Run workflow"
Optionally override intent configuration

3. Pre-Release Validation

For Pull Requests:

Release validation runs automatically on PRs to master
Provides comprehensive validation without publishing
Reviews security scan results and vulnerability reports

Manual Validation:

# Trigger validation workflow manually
gh workflow run release-validate.yml

4. Staging Releases

Deploy to Staging:

# Manual staging release
gh workflow run release-staging.yml

Staging Artifacts:

TestPyPI: pip install -i https://test.pypi.org/simple/ test-python-uv-project-template
GHCR Staging: docker pull ghcr.io/chisanan232/test-python-uv-project-template:1.0.0-rc.0
Preview Docs: Available on docs-preview branch

Common Workflows

Release Preparation

Update Code: Make your changes and ensure tests pass
Configure Intent: Set release configuration in intent.yaml
Validate: Create PR and review validation results
Stage (Optional): Test in staging environment
Release: Merge to master for automatic release

Troubleshooting

Git Synchronization Issues:

Fixed: Critical issue where artifacts built with old version (0.0.0) instead of bumped version (0.0.1)
Root Cause: Downstream jobs used actions/checkout@v5 without ref parameter, defaulting to original commit SHA
Solution: All workflows now use ref: ${{ github.ref_name }} to checkout latest branch state
Impact: Python packages, Docker images, and docs now use correct bumped version

UV Lock File Synchronization:

Enhanced: Version bump now automatically updates uv.lock file to maintain dependency synchronization
Process: After uv version --bump, the workflow runs uv lock to update lock file
Commit: Both pyproject.toml and uv.lock are committed together in version bump
Benefit: Ensures dependency lock file stays in sync with version changes

Tag Mismatch Issues:

Check that Docker build and security scan jobs use consistent tags
Validation workflow includes defensive checks to catch this early

SBOM Generation Failures:

System includes fallback SBOM generation from workspace
Check security scan artifacts for detailed logs

Best Practices

Use Conservative Configuration: Start with auto settings and change detection
Validate Before Release: Always run validation workflows on PRs
Test in Staging: Use staging environment for major releases
Monitor Security: Review security scan results and vulnerability reports
Version Documentation: Keep documentation in sync with code changes
