Usage with kubernetes/ingress-nginx #1
Description
Hi!
I'm trying to compile custom dynamic module and use it with ingress-controller 0.44.0 (https://github.com/kubernetes/ingress-nginx/). I made a fork to slightly modify config file to compile it as a dynamic module. https://github.com/chainstack/ngx_http_websocket_stat_module
The resulting dynamic module works fine with pure nginx 1.19.6. But the problem is that when I'm trying to use with ingress-nginx image, it does nothing. No frames are logged and no errors appear:(
I know that it's not a problem of the module itself, but maybe you guys can advise me smth to look at.
This is the dockerfile I came up with to build an nginx with the dynamic module inside.
FROM k8s.gcr.io/ingress-nginx/controller:v0.44.0 as builder
USER root
WORKDIR /tmp
RUN apk add git openssl-dev pcre-dev zlib-dev libc-dev gcc make
RUN NGINX_VERSION=$(nginx -v 2>&1 | sed 's/nginx version: nginx\///') && \
wget -qO- https://nginx.org/download/nginx-${NGINX_VERSION}.tar.gz | tar xvz && \
mv nginx-${NGINX_VERSION} nginx
RUN git clone --depth 1 --branch v1.0.0 https://github.com/chainstack/ngx_http_websocket_stat_module.git && \
cd ./nginx && \
./configure --with-compat --add-dynamic-module=../ngx_http_websocket_stat_module && make modules
FROM k8s.gcr.io/ingress-nginx/controller:v0.44.0
COPY --from=builder /tmp/nginx/objs/ngx_http_websocket_stat_module.so /etc/nginx/modules
The way I was testing it is the following:
- I ran docker container from the image
- Added
load_module /etc/nginx/modules/ngx_http_websocket_stat_module.so;to/etc/nginx/nginx.conffile - Added an nginx service and location sections that accept websocket and proxies it to a dummy websocket backend.
- Finally added
ws_log*directives to the addedservice.
P.S.
Maybe you guys know some other way that allows to log each time frame goes through websocket connection.
