ClamAV + c-icap Docker Container

This container provides a lightweight Debian-based image that runs ClamAV integrated with c-icap for virus scanning over ICAP. It's suitable for use with proxies (like Squid) that support ICAP for content filtering.

🧰 Features

• Based on debian:bookworm-slim
• Installs:
  • clamav
  • clamav-daemon
  • c-icap
  • libicapapi-dev
  • libc-icap-mod-virus-scan
• Fresh virus definitions via freshclam at build time
• Handles headless install issues (debconf, service start)
• Proper permissions for ClamAV and c-icap runtime
• Simple entrypoint.sh for container initialization
• The versioning follows the ClamAV version used in the base image

🔍 Service Details

The container exposes two ICAP services on port 1344:

• avscan - Main antivirus scanning service
• srv_clamav - Legacy service name (maintained for backward compatibility)

🚀 Usage

Once the container is running, you can access the ICAP services at:

• icap://localhost:1344/avscan
• icap://localhost:1344/srv_clamav
