This docker container provides highly efficient load balancer which is HAproxy however to enrich logging of details it also provides syslog information.
At the moment the docker image contains only single tag - which is latest and points to latest from HAproxy repository.
docker pull rafpe/docker-haproxy-rsyslog
In order to run container (assuming you have an haproxy config file) you can just run the following
docker run -d -P -v ${PWD}/haproxy.cfg:/usr/local/etc/haproxy/haproxy.cfg rafpe/docker-haproxy-rsyslog
This is of course only basic example since you will for sure need to adjust it to your requirements like ports/networks/volumes etc.
