Review

Summary of Changes

• Dockerfile switched to Debian Bookworm, enabled CGO for SQLite compatibility, added necessary dependencies and persistent volume mounts.
• Server configuration improved for production: environment-based Gin mode, custom minimal logger, and graceful shutdown.
• Storage updated for flexible path handling, defaulting to /app/data/simple-sync.db inside the container.
• Added data/ to .dockerignore and .gitignore for better Docker builds and repository hygiene.

Overall Feedback

No changes requested—these updates address the CGO issue for SQLite and add production-ready features like graceful shutdown. The volume mounts should resolve the database persistence TODO. Excellent work improving the Docker setup! 😊

@Pertempto, the custom logger formatter in src/main.go has a bug: the fmt.Sprintf uses %s for param.StatusCode, which is an int, causing a runtime panic due to format mismatch. Also, it misses param.Protocol and has incorrect ordering, plus an extra placeholder in the format string. Consider fixing it to:

return fmt.Sprintf("%s - %s \"%s %s %s\" %d %s \"%s\"\n",
    param.TimeStamp.Format(time.RFC3339),
    param.ClientIP,
    param.Method,
    param.Path,
    param.Protocol, // Added protocol
    param.StatusCode,
    param.Latency,
    param.ErrorMessage)

Note the %d for status code and added protocol.

@Pertempto, just a quick check on the TODO in the PR description about getting the database file to work properly inside docker. Any update on that, or is it resolved with these changes?

Still working on that...
