Increase the filesize scans

[zodman]

if you need big files over 25mb like 500/600 mb, you need to change this configurations:
from clamad
StreamMaxLength
MaxFileSize
StreamMaxLength

from the app:
CLAMD_TIMEOUT=300000

Here how to do:

# Dockerfile 
# for clamav with settings change
from clamav/clamav

RUN \ 
    sed  -i \ 
        -e "s|^\#\(MaxFileSize\).*|\1 512M|" \
        -e "s|^\#\(MaxScanSize\).*|\1 512M|" \
        -e "s|^\#\(StreamMaxLength\).*|\1 512M|" \
        /etc/clamav/clamd.conf
RUN cat /etc/clamav/clamd.conf | sed "s/#.*$//g" | awk 'NF'

# docker-compose.yaml
version: '3.8'
services:
  clamd:
    build: .
    restart: unless-stopped
    environment:
      - CLAMAV_NO_MILTERD=true
    networks:
      - clam-net
  api:
    image: benzino77/clamav-rest-api
    restart: unless-stopped
    command: ['/usr/bin/wait-for-it', '-h', 'clamd', '-p', '3310', '-s', '-t', '60', '--', 'npm', 'start']
    depends_on:
      - clamd
    environment:
      - NODE_ENV=production
      - CLAMD_IP=clamd
      - APP_FORM_KEY=FILES
      - APP_PORT=3000
      - CLAMD_TIMEOUT=300000
    ports:
      - '8080:3000'
    networks:
      - clam-net
networks:
  clam-net:

run:

docker-compose up --build --build --force-recreate  --remove-orphans -V

create a file with 500mb and upload

head -c 500MB /dev/urandom > 500mb.bin
curl -F FILES=@./500mb.bin http://localhost:8080/api/v1/scan

{"success":true,"data":{"result":[{"name":"500mb.bin","is_infected":false,"viruses":[]}]}}
