Summary

Add complete Docker containerization with multi-architecture builds, GitHub Actions CI/CD pipeline, and development tooling.

Docker Features

  • Multi-stage Dockerfile: Python 3.11-slim base with optimized layers
  • Multi-architecture: Builds for linux/amd64 and linux/arm64
  • s6-overlay init system: Proper process management and user/group handling
  • Environment variable validation: Fails fast if required credentials are missing
  • Health checks: SQLite database connectivity validation
  • Volume mounts: Persistent data at /config/data and logs at /config/logs
  • PUID/PGID support: Flexible user mapping for file permissions
  • Resource limits: Memory and CPU constraints via docker-compose

CI/CD Pipeline

  • GitHub Actions workflow: Automated builds on push to main/develop/feature branches
  • Multi-platform builds: Uses buildx for amd64 and arm64
  • Container registry: Publishes to GitHub Container Registry (ghcr.io)
  • SBOM generation: Software bill of materials for supply chain security
  • Security scanning: Trivy vulnerability scanner with SARIF upload
  • Caching: GitHub Actions cache for faster builds

Development Tooling

  • Pre-commit hooks: Black (180 char), flake8, isort, mypy, detect-secrets
  • EditorConfig: Consistent coding styles across editors
  • Code formatting: Python reformatted with 180 character line limit

Configuration Changes

  • Data directory: Changed from /app/data to /config/data for consistency
  • Startup validation: Container exits if required env vars are unset/empty:
    • REDDIT_CLIENT_ID
    • REDDIT_CLIENT_SECRET
    • REDDIT_USERNAME
    • REDDIT_PASSWORD
    • SOURCE_SUBREDDIT

Documentation

  • Deployment options: Clarified Docker (recommended), systemd, and native Python
  • Docker Compose: Example with environment variables and volume mounts
  • README updates: Multi-arch image references, env var documentation

Breaking Changes

None - existing systemd deployments continue to work. Docker is an additional deployment option.

Migration Path

For users currently running with systemd who want to migrate to Docker, a separate migration guide and Hetzner-specific docker-compose files will be provided after merge.

Commit History

  1. feat: add Docker support and improved systemd configuration
  2. docs: clarify deployment options for Docker, systemd, and native
  3. fix: improve Docker configuration with validation and path fixes
  4. fix: address critical multi-arch and CI/CD issues
  5. chore: restore pre-commit configuration
  6. chore: add EditorConfig for consistent coding styles
  7. chore: reformat Python code with 180 char line limit

Testing

  • Docker build succeeds locally
  • Multi-arch builds (amd64/arm64)
  • GitHub Actions CI passes (pending)
  • Copilot security review (pending)

Features:
- Complete Docker containerization with s6-overlay init
- PUID/PGID support for proper file permissions
- Multi-architecture builds (amd64/arm64)
- GitHub Actions CI/CD pipeline for ghcr.io publishing
- OpenContainer labels for proper metadata

Systemd improvements:
- Template-based service for multiple subreddits
- Per-subreddit config files in /etc/redditmodlog/
- Centralized logging to /var/log/redditmodlog/
- Automatic log rotation (30 days, 100MB max)
- Security hardening with read-only filesystem
- Resource limits (256MB RAM, 25% CPU)

Infrastructure:
- Installation script for easy deployment
- Logrotate configuration included
- Enhanced .gitignore for sensitive files
- Updated README with Docker and systemd documentation

This provides production-ready deployment options for both Docker and systemd environments.
- Change data directory from /app to /config for consistency
- Add startup validation for critical environment variables
- Fix GitHub Actions workflow image name to lowercase (GHCR requirement)
- Fix health check to use DATABASE_PATH env var
- Update all volume mounts to use /config instead of /app
- Add proper exit on missing required env vars:
  - REDDIT_CLIENT_ID
  - REDDIT_CLIENT_SECRET
  - REDDIT_USERNAME
  - REDDIT_PASSWORD
  - SOURCE_SUBREDDIT
- Simplify GitHub Actions tag pattern (remove invalid branch prefix)
- Update README documentation for /config paths
Critical fixes from expert review:
- Fix multi-arch builds: s6-overlay now selects correct architecture
  (x86_64 for amd64, aarch64 for arm64, arm for arm/v7)
- Fix GitHub Actions SBOM generation image reference
- Fix GitHub Actions Trivy security scan image reference
- Fix resource limits: use Compose v2 syntax instead of swarm-only deploy
- Remove obsolete version directive from docker-compose.yml
- Remove unnecessary reverse proxy network comments
- Document unsupported env vars (MAX_WIKI_ENTRIES_PER_PAGE, MAX_CONTINUOUS_ERRORS)

This resolves blocking issues for arm64 builds and CI/CD pipeline.
Restore .pre-commit-config.yaml that was in original PR but missing from
current branch. This file provides code quality, security scanning, and
formatting validation hooks.
Add .editorconfig to maintain consistent formatting across editors:
- Python: 4 spaces, max line 88 (matches black)
- YAML/JSON: 2 spaces
- Unix line endings (LF)
- UTF-8 encoding
- Trim trailing whitespace
- Black reformatted with --line-length=180
- Fixed trailing whitespace and EOF issues
- Fixed Dockerfile FROM casing (AS instead of as)

Pull Request Overview

This pull request standardizes code formatting across the entire codebase using Black formatter and adds comprehensive tooling/infrastructure. The changes focus on code style consistency (quotes, whitespace, line breaks) and adding Docker deployment support with CI/CD workflows.

  • Code formatting standardized to use double quotes instead of single quotes
  • Trailing whitespace removed across all files
  • Added Docker support with multi-architecture builds (amd64, arm64)
  • Added development tooling (.pre-commit-config.yaml, .editorconfig, .dockerignore)

This line is 180 characters long which makes it difficult to read and review. Consider splitting this list across multiple lines for better readability, especially since it contains 6 tuples. Example: one tuple per line or grouping 2-3 tuples per line.

Suggested change
columns_to_add = [("action_type", "TEXT"), ("moderator", "TEXT"), ("target_id", "TEXT"), ("target_type", "TEXT"), ("display_id", "TEXT"), ("target_permalink", "TEXT")]

The inline comment explains 'Use A for action ID when dealing with user actions' but this is misleading since 'U' is mapped to 'user', not 'A'. The comment should be moved above the line or removed if it's outdated, as it currently suggests a mapping that doesn't match the code.

Suggested change
prefixes = {"post": "P", "comment": "C", "user": "U", "action": "A"} # Use 'A' for action ID when dealing with user actions
prefixes = {"post": "P", "comment": "C", "user": "U", "action": "A"}

Import of 'timezone' is not used.

Suggested change
from datetime import datetime, timezone
from datetime import datetime

- Split long tuple list for better readability (line 270)
- Fix misleading comment about prefix mapping
- Remove unused timezone import from test file
- Add .secrets.baseline for detect-secrets
- Extend flake8 ignore list for existing code issues
Docker tags cannot contain slashes, so metadata-action converts
branch names like 'feature/docker-v2' to 'feature-docker-v2'.
Use steps.meta.outputs.version which has the correct format.
