[bug] Ignored error on flags.logFile.Close()

[docker-agent]

🟡 medium - bug

File: cmd/root/root.go (line 104)

Code

_ = flags.logFile.Close()

Problem

The error returned by flags.logFile.Close() is ignored. If closing the log file fails, it could indicate a resource leak or a problem with flushing buffered data. While generally not critical for program functionality, ignoring such errors can hide underlying issues, especially in long-running processes or when dealing with full disks.

Suggested Fix

The error from flags.logFile.Close() should be handled, perhaps by logging it. For example:

if err := flags.logFile.Close(); err != nil {
    slog.Error("Failed to close log file", "error", err)
}
