haproxy-waf

Introduction

The main work is based on Thierry Fournier patches and of course the SPOE feature of haproxy.

You can see the start and following discussion on the haproxy mailing list. https://www.mail-archive.com/[email protected]/msg25681.html

You are able with this patches to use haproxy as SSL terminator and WAF (Web Application Firewall) based on mod_security.

requirements

You will need this tools to run this docker file on centos

yum -y install docker bash-completion git
systemctl start docker

build

Now you can clone & build this repo with common commands

git clone https://github.com/git001/haproxy-waf.git
cd haproxy-waf
docker build -t haproxy-waf .

test

You can see if the build works with the docker run command

docker run --entrypoint /usr/local/sbin/haproxy --rm haproxy-waf -vv

haproxy use

I have uploaded the image into docker hub

https://hub.docker.com/r/me2digital/haproxy-waf/

from where you can use this image with the following command.

$ docker run --rm -it --name my-running-haproxy \
    -e TZ=Europe/Vienna \
    -e STATS_PORT=1999 \
    -e STATS_USER=aaa \
    -e STATS_PASSWORD=bbb \
    -e SYSLOG_ADDRESS=127.0.0.1:8514 \
    -e SERVICE_TCP_PORT=13443 \
    -e SERVICE_NAME=test-haproxy \
    -e SERVICE_DEST_PORT=8080 \
    -e SERVICE_DEST='1.2.3.4;5.6.7.8;80.44.22.7' \
    me2digital/haproxy-waf /bin/bash

The output of the command above should be something like this
