如何在 kube.netes 中为 nginxinc/nginx-ingress 配置添加第三方模块？

Question

Goal:

I am trying to include a thirdparty module a Http_more_headers to provide a custom name to the server in the headers.

I am able to build a custom controller image with the module installed with a slightly tweaked DockerFile.

Issue:

To enable this third party module I need to add the load_module directive in the nginx.conf I am however confused on how the ingress controller interprets the nginx.conf file. If I add the load_module in the server-snippet annotation, will it work? or do I have to modify the.tmpl file to enable the third party module? or should I just modify the nginx.conf and use a COPY during the image build itself? which would be the best way to achieve the goal?

Answer 1

Use the "main-snippets" configMap key under "data" followed by the value "load_module <module_path>"

example:

kind: ConfigMap
apiVersion: v1
data:
  main-snippet: load_module /usr/lib/modules/xyz_module.so
