Ingress NginX TCP UDP

It’s quite difficult to set & no precise document to follow. However here it is

1. install ingress-nginx

2. patch controller deployment & service

3. register TCP configmap

create your deployment

create your service

check TCP connection (UDP is same with word changing)

Exposing TCP and UDP services - NGINX Ingress Controller

Ingress does not support TCP or UDP services. For this reason this Ingress controller uses the flags --tcp-services-configmap and --udp-services-configmap to point to an existing config map where the key is the external port to use and the value indicates the service to expose using the format: : :[PROXY]:[PROXY] It is also possible to use a number or the name of the port.
