This is two in one docker image so it runs open source virus scanner ClamAV (https://www.clamav.net/), automatic virus definition updates as background process and REST API interface to interact with ClamAV process.
As of May 2024, the releases are built for multiple architectures thanks to efforts from kcirtapfromspace and support non-root read-only deployments thanks to robaca.
The additional endpoint /version is now available to check the clamd version and signature date. Thanks pastral.
Closed a security hole by upgrading our Dockerfile to the alpine base image version 3.19 thanks to Marsup.
This container doesn't do much on it's own unless you use an additional service or communicator to talk to it!
Automated builds of the image are available on Registry and is the recommended method of installation.
docker pull hub.docker.com/ajilaag/clamav-rest:(imagetag)The following image tags are available:
latest- Most recent release of ClamAV with REST APIYYYYMMDD- The day of the releasesha-...- The git commit sha. This version ensures that the exact image is used and will be unique for each build
See this docker-compose file for non-root read-only usage.
