Ingress-nginx: nginx-ingress-controller can't modify parameter port (http 80 / https 443) by other port

[tiandong19860806]

NGINX Ingress controller version: 0.25.1

Kubernetes version: v1.14.1

Environment: CentOS 7 x64
Linux CNT7XDCK11D01 4.4.190-1.el7.elrepo.x86_64 #1 SMP Sun Aug 25 07:32:44 EDT 2019 x86_64 x86_64 x86_64 GNU/Linux

What happened: when I modify the installation yaml file's parameter http port and https port by new value, but actual the netstat commad query result : nginx-ingress-controller's used port still is 80 and 443.

What you expected to happen:
when I modify the installation yaml file's port parameter by 11180(http) and 11443(https),
After deploy the nginx used node-port also is 11180(http) and 11443(https),
not the default value 80(http) and 443(https).

How to reproduce it:
* clear old
root >> kubectl delete the deployment --al -n ingress-nginx
root >> kubectl delete the configmap --al -n ingress-nginx
* install
root >> kubectl apply -f {path, my modify file as below attachment: all_ingress_deploy.yaml}

Anything else we need to know:

1. deployment, I modify port as below:
   ports:
   - name: http
   containerPort: 11180
   - name: https
   containerPort: 11443

1. service, I modify port as below:
   type: NodePort
   ports:

   • name: http
     port: 11180
     targetPort: 11180
     protocol: TCP
     nodePort: 30080
   • name: https
     port: 11443
     targetPort: 11443
     protocol: TCP
     nodePort: 30443

2. deploy result, as below:

Closing. You are just changing the service ports. You need to change the deployment arguments https://kubernetes.github.io/ingress-nginx/user-guide/cli-arguments/
and specify --http-port and --https-port flags

Hi Aledbf,
Thanks very much, I follow your manual is OK, as below:

step 1: add deploy flag,

step 2: deploy it

step 3: query the ingress-nginx-controller actual port, is OK
