The official documentation can be found here.

How to expose multiple services with tcp using nginx-ingress?

Let’s say:

apiVersion: v1
kind: ConfigMap
metadata:
name: tcp-services
namespace: ingress-nginx-private
data:
3389: “demo/rdp:3389”`

will expose a “rdp” service. If we have 10 services which need to be exposed the same way than how can we achieve that?

    You will need to edit this configmap with your new port dynamically.

    You could also use Traefik V2, they democratized the TCP/UDP Service through a CRD.

    But both case, you need to edit a manifest on the kube.

    As mentioned by nginx ingress docs here: user-guide/exposing-tcp-udp-services

    You need to edit configmap:

    apiVersion: v1
kind: ConfigMap
metadata:
  name: tcp-services
  namespace: ingress-nginx
data:
  9000: "default/example-0:8080" 👈
  9001: "default/example-1:8080" 👈
  9002: "default/example-2:8080" 👈

    And nginx ingress service:

    apiVersion: v1
kind: Service
metadata:
  name: ingress-nginx
  namespace: ingress-nginx
  labels:
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/part-of: ingress-nginx
spec:
  type: LoadBalancer
  ports:
    - name: http
      port: 80
      targetPort: 80
      protocol: TCP
    - name: https
      port: 443
      targetPort: 443
      protocol: TCP
    - name: proxied-tcp-9000  👈
      port: 9000
      targetPort: 9000
      protocol: TCP
    - name: proxied-tcp-9001  👈
      port: 9001
      targetPort: 9001
      protocol: TCP
    - name: proxied-tcp-9002  👈
      port: 9002
      targetPort: 9002
      protocol: TCP
  selector:
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/part-of: ingress-nginx

    And you can add as many ports as you’d like. Just remeber that one port can only be used once.
