Ingress-nginx随记

Ingress nginx annotation doc

https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/annotations/

use-forwarded-headers

https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/configmap/#use-forwarded-headers

If false, NGINX ignores incoming X-Forwarded-* headers, filling them with the request information it sees. Use this option if NGINX is exposed directly to the internet, or it's behind a L3/packet-based load balancer that doesn't alter the source IP in the packets.

Lua 相关

nginx 原生是不支持Lua的, Ingress nginx能用lua是因为引用了 openresty/lua-nginx-module

需要特别注意的是 rewrite_by_lua_block always runs after the standard ngx_http_rewrite_module.
