Quick Set up NGINX with Modsecurity through Docker

Reference: https://hub.docker.com/r/owasp/modsecurity-crs

1) Pull the docker image first:
#/etc/init.d/docker start
#docker pull owasp/modsecurity-crs

2) Suppose Apache2 is running on the TCP81 of the server, and execute the following commands:
#/etc/init.d/apache2 start

3) Run the image:
#docker run -d -p 80:80 -e PARANOIA=5 -e PROXY=1 -e PROXYLOCATION=[URL] owasp/modsecurity-crs
Example:
#docker run -d -p 80:80 -e PARANOIA=5 -e PROXY=1 -e PROXYLOCATION=http://8.8.8.8:81/ owasp/modsecurity-crs

4) Check Modsecurity's log:
#docker exec -it [CONTAINER NAME] tail -n 30 -f /var/log/modsec_audit.log
Example:
#docker exec -it sweet_swartz tail -n 30 -f /var/log/modsec_audit.log
