ClamAV docker image

Dockerized open source antivirus daemons for use with

• Firstly, file sharing containers like Nextcloud or
• Then, to use it via a REST proxy like @solita made clamav-rest or
• Next, to directly connect to clamav via TCP port 3310

ClamAV daemon as a Docker image.

Usually, it builds with a current virus database and runs freshclam in the background constantly updating the virus signature database.

clamd itself is listening on exposed port 3310.

There are different releases for the different platforms.

Installation Instructions

Using Docker

ClamAV can be run using Docker.

Then for details, visit to the online manual under “Docker” and check out our images on Docker Hub.

Using a Package Manager

Here for help installing from a package manager, refer to the online manual under “Packages”.

Using an Installer

The following install packages are available for download from clamav.net/downloads:

• Firstly, linux – Debian and RPM packages for x86_64 and i686. New in v0.104.
• Secondly, macOS – PKG installer for x86_64 and arm64 (universal). New in v0.104.
• Thirdly, Windows – MSI installers and portable ZIP packages for win32 and x64.

Then, to learn how to use these packages, refer to the online manual under “Installing”.

Build from Source

For step-by-step instructions, refer to the online manual:

• Unix/Linux/Mac
• Windows

Usually, the source archive for each release includes a copy of the documentation for offline reading.

Then, a reference with all of the available build options can be found in the INSTALL.md file.

Usage

The container run as user clamav with uid=101 and gid=102.

Debian

• buster-slim
• stretch-slim docker run -d -p 3310:3310 mkodockx/docker-clamav:buster-slim

Alpine

• alpine
• alpine-edge docker run -d -p 3310:3310 mkodockx/docker-clamav:alpine

Linked usage recommended, to not expose the port to “everyone”.

    docker run -d --name av mkodockx/docker-clamav(:alpine)
    docker run -d --link av:av application-with-clamdscan-or-something

Environment VARs

Proxy

Thanks to @mchus proxy configuration is possible.

• HTTPProxyServer: Allows to set a proxy server
• HTTPProxyPort: Allows to set a proxy server port

Database Mirror

Specifying a particular mirror for freshclam is also possible.

• DatabaseMirror: Hostname of the mirror web server.

Custom Configuration Files

Mount custom configuration files into the container.

• FRESHCLAM_CONF_FILE: Path to custom freshclam.conf file, e.g. /mnt/freshclam.conf.
• CLAMD_CONF_FILE: Set the path to a custom clamd.conf file, e.g. /mnt/clamd.conf.

Persistency

Virus update definitions are stored in /var/lib/clamav. To store the defintion just mount the directory as a volume, docker run -d -p 3310:3310 -v ./clamav:/var/lib/clamav mkodockx/docker-clamav:latest

Healthcheck

The images provide with check.sh a file to check for the healthyness of the running container.

To enable the health check configure your docker run or compose file.

Then, the start period should adjust to your system needs.

Finally slow internet connection, with limited cpu and IO speed might require larger values.
