When I run nginx based image of owasp/modsecurity-crs on top of kubernetes, I get this error:
/nginx/modsecurity.d/modsecurity.conf
/docker-entrypoint.d/20-envsubst-on-templates.sh: 53: envsubst: Argument list too long

kubectl run mynginxtest --image=owasp/modsecurity-crs:4.8.0-nginx-202411071011

Hi @imikiani,

thanks for reporting - but I'm afraid this is more a modsecurity-crs-docker issue than a ModSecurity.

Dear @airween ,
Sorry, maybe it would have been better if I had opened the issue on modsecurity-crs-docker.

No problem. Feel free to close this issue if you don't have any questions.
