Clam Scanner is a Go-based utility designed to scan files using ClamAV by communicating with a clamd daemon process through Unix domain sockets. The tool integrates with OpenShift and container environments to provide malware detection and threat scanning capabilities across filesystem and container images.
The core functionality of Clam Scanner centers on submitting file descriptors to a running clamd process over a Unix domain socket connection. This architecture allows the scanner to leverage ClamAV's malware detection engine without requiring direct file access patterns, instead using file descriptor passing for efficient scanning operations. The tool is written in Go and depends on several key libraries including glog for logging, cobra for command-line interface construction, and pflag for flag parsing.
The primary command interface is the scan command, which accepts two essential flags. The --path flag specifies the filesystem location to be scanned, while the --socket flag designates the Unix domain socket endpoint where the clamd daemon is listening. Users can optionally employ the --omit-negative-results flag to filter output and exclude files that return negative or "OK" scan results, reducing noise in the output when only threats are of interest.
Clam Scanner is containerized through an included Dockerfile, enabling deployment as a container image. When running as a container, the tool requires privileged mode and specific volume mounts to function properly. The clamd socket must be mounted from the host system to /run/clamd.scan/clamd.sock within the container, and the filesystem path to be scanned should be mounted to /tmp/scan-data. This containerized approach facilitates integration with OpenShift clusters and other container orchestration platforms.
According to GitGenius activity classification, this repository falls within multiple security-focused domains including threat intelligence, malware detection, antivirus integration, container security, and vulnerability scanning. The project is categorized as supporting security compliance auditing, file integrity monitoring, real-time scanning, and CVE database integration through ClamAV's threat definitions. The classifications also indicate relevance to Linux package management, software repository scanning, and OSS vulnerability analysis, suggesting the tool is used to scan container images and software artifacts for known threats.
The repository serves the OpenShift ecosystem specifically, providing a native integration point for ClamAV scanning within containerized and Kubernetes-based environments. This positioning makes it valuable for organizations running OpenShift clusters that require malware scanning as part of their container image validation and security compliance workflows. The tool addresses the need for scanning container images and mounted filesystems against ClamAV's malware signature database before deployment or during runtime monitoring.
Building the tool requires installing Go dependencies and using the standard go install command, making it straightforward for developers to compile and deploy. The combination of Unix socket communication with clamd, containerization support, and OpenShift integration makes Clam Scanner a specialized security tool designed for modern container-based infrastructure rather than traditional filesystem scanning scenarios.
