node exporter can not bind the port

My node exporter was installed using kubernetes daemonset. The default port of node exporter is 9100, but the port on my local machine is already occupied, So I modify the config file serveral times to change the port. But it failed every time. the following config was what I have tried: tryied times 1(modify the 9100 port to 19100):

containers：
- name: prometheus-node-exporter
  image: "docker.ssiid.com/prom/node-exporter:v0.18.1"
  imagePullPolicy: "IfNotPresent"
  args:
    - --path.procfs=/host/proc
    - --path.sysfs=/host/sys
  ports:
    - name: metrics
      containerPort: 19100
      hostPort: 19100
  volumeMounts:
    - name: proc
      mountPath: /host/proc
      readOnly:  true
    - name: sys
      mountPath: /host/sys
      readOnly: true

the result is does't work. It's still using port 9100 from the log

tried times 2(add new option to args - --web.listen-address=":9100") like below:

containers:
- name: prometheus-node-exporter
  image: "docker.ssiid.com/prom/node-exporter:v0.18.1"
  imagePullPolicy: "IfNotPresent"
  args:
    - --web.listen-address=":19100"
    - --path.procfs=/host/proc
    - --path.sysfs=/host/sys
  ports:
    - name: metrics
      containerPort: 9100
      hostPort: 9100
  volumeMounts:
    - name: proc
      mountPath: /host/proc
      readOnly:  true
    - name: sys
      mountPath: /host/sys

it still does not work. the error like this:

time="2020-03-13T10:56:03Z" level=info msg=" - time" source="node_exporter.go:104"
time="2020-03-13T10:56:03Z" level=info msg=" - timex" source="node_exporter.go:104"

time="2020-03-13T10:56:03Z" level=fatal msg="listen tcp: address tcp/19100\": unknown port" source="node_exporter.go:172"

the following config is effective:

containers:
- name: prometheus-node-exporter
  image: "docker.ssiid.com/prom/node-exporter:v0.18.1"
  imagePullPolicy: "IfNotPresent"
  args:
    - --web.listen-address=localhost:19100
    - --path.procfs=/host/proc
    - --path.sysfs=/host/sys
  ports:
    - name: metrics
      containerPort: 19100
