How ingress-nginx image was built?

[guyni]

I don't see the /etc/ingress-controller/geoip and /etc/ingress-controller/telemetry folder in the registry.k8s.io/ingress-nginx/controller:v1.9.6 image. I am wondering if you use the Dockerfile below to build that image.

https://github.com/kubernetes/ingress-nginx/blob/controller-v1.9.6/rootfs/Dockerfile#L54-L55

$ docker run --entrypoint sh --rm -it registry.k8s.io/ingress-nginx/controller:v1.9.6 /etc/nginx $ ls -l /etc/ingress-controller/ total 8 drwxr-xr-x 2 www-data www-data 4096 Jan 19 20:21 auth drwxr-xr-x 2 www-data www-data 4096 Jan 19 20:21 ssl

I think there was a PR to move from geoip to geoip2. If you search the PRs then you may find it. That could contain some info on this.

Otel is now a addon module.

regardless if geoip and otel were moved or not. If I check out the controller-v1.9.6 tag to build the image by myself, I can see the /etc/ingress-controller/geoip and /etc/ingress-controller/telemetry folders, which are not in registry.k8s.io/ingress-nginx/controller:v1.9.6. If I replaced the ingress controller binary in registry.k8s.io/ingress-nginx/controller:v1.9.6 with the one that I built, it would complain those folders were missing and exit. So I am wondering if registry.k8s.io/ingress-nginx/controller:v1.9.6 was built from controller-v1.9.6 tag, or other release tag.

1.9. is built from v1.9.6 branch and not main

main is to allow us to merge changes but not break release branches; we cherry-pick what we want in a release to the release branch.

The nginx base image is built here https://github.com/kubernetes/ingress-nginx/tree/main/images/nginx

And the controller is build https://github.com/kubernetes/ingress-nginx/tree/main/rootfs

Each image is built in cloud build with the make build commands and promoted to the k8s.io registry
