Is this a BUG REPORT or FEATURE REQUEST? (choose one):BUG

NGINX Ingress controller version: 0.12.0

Kubernetes version (use kubectl version): 1.9.6

Environment:

• Cloud provider or hardware configuration:
• OS (e.g. from /etc/os-release): Ubuntu 16.04 and RHEL 7.3
• Kernel (e.g. uname -a): s390x
• Install tools: docker
• Others:

What happened:
I am trying to deploy nginx-ingress-controller, but nginx-ingress-controller POD is not getting up.
default-http-backend POD is running.
Using gcr.io/google-containers/defaultbackend-s390x:1.4 image in default-backend.yaml
and for nginx-ingress-controller I am using quay.io/kubernetes-ingress-controller/nginx-ingress-controller-s390x:0.12.0 in with-rbac.yaml.
I also tried to build local docker image for nginx-ingress-controller and nginx, but still I am not able to start nginx-ingress-controller POD.

What you expected to happen:
Using this quay.io/kubernetes-ingress-controller/nginx-ingress-controller-s390x:0.12.0 image POD should get up on s390x.

Anything else we need to know:
Please check error log in comment section.

Closing. Fixed in #2298
The error is related to the new dynamic configuration feature not available in s390x (LuJIT)

[srajmane]

I have changed flags.go file as per fix and built nginx-ingress-controller with make ARCH=s390x build container and created docker image. Edit with-rbac.yaml with new docker image, but still I am facing same issue "init_by_lua error: /usr/local/lib/lua/resty/core/uri.lua:4: module 'ffi' not found:"

@aledbf even after apply your patch, we still have the same issue, can you help check? I think that we still need this open.

[oilbeater]

only this patch cannot fix the problem, you should also update the nginx.tmpl in #2263.
However I see the master nginx.tmpl still leak some lua part if enable waf , this part should also be removed @aledbf
