This container allows you a very simple way to scan a mounted directory using clamscan.

It will always update the ClamAV Database, by using the standard freshclam before running clamscan. If the local ClamAV Database is up-to-date, it will check and continue.

How-To

Usage

Using this image is fairly straightforward.

Pay attention to -v /path/to/scan as this is the mounted directory that this docker image will scan.

docker run -it \
  -v /path/to/scan:/scan:ro \
  tquinnelly/clamav-alpine -i

Use -d instead of -it if you want to detach and move along.

Post-Args

I took the liberty to include -i by default. You can, however, add any you desire.

• -i - Only print infected files
• --log=FILE - save scan report to FILE
• --database=FILE/DIR - load virus database from FILE or load all supported db files from DIR
• --official-db-only[=yes/no(*)] - only load official signatures
• --max-filesize=#n - files larger than this will be skipped and assumed clean
• --max-scansize=#n - the maximum amount of data to scan for each container file
• --leave-temps[=yes/no(*)]- do not remove temporary files
• --file-list=FILE - scan files from FILE
• --quiet - only output error messages
• --bell - sound bell on virus detection
• --cross-fs[=yes(*)/no] - scan files and directories on other filesystems
• --move=DIRECTORY - move infected files into DIRECTORY
• --copy=DIRECTORY - copy infected files into DIRECTORY
• --bytecode-timeout=N - set bytecode timeout (in milliseconds)
• --heuristic-alerts[=yes(*)/no] - toggles heuristic alerts
• --alert-encrypted[=yes/no(*)] - alert on encrypted archives and documents
• --nocerts - disable authenticode certificate chain verification in PE files
• --disable-cache - disable caching and cache checks for hash sums of scanned files

Volumes

I only have the /scan directory noted above. You can add others in conjunction with the post-args as well.

Save AV Signatures

• -v /path/to/sig:/var/lib/clamav

Infected Dir

• -v /path/to/infected:/infected
• Then you can use either the --move or --copy post-arg above.

Examples

Here are some examples of various configurations.

This is the one I run. I target 2 cores of my CPU as to not cripple my host. I also log to the DB directory and limit 2G file size scan.

docker run -d --name=ClamAV \
  --cpuset-cpus='0,1' \
  -v /path/to/scan:/scan:ro \
  -v /path/to/sig:/var/lib/clamav:rw \
  tquinnelly/clamav-alpine -i --log=/var/lib/clamav/log.log --max-filesize=2048M

Expected Output

# docker run -it -v /path:/scan:ro tquinnelly/clamav-alpine -i
