我的节点导出器是使用 kubernetes daemonset 安装的。node exporter的默认端口是9100，但是我的本地机器上的端口已经被占用了，所以我多次修改config文件来更改端口。但每次都失败了。以下配置是我尝试过的：tryied times 1（将 9100 端口修改为 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

结果是行不通。它仍在使用日志中的端口 9100

尝试了 2 次（向 args 添加新选项 - --web.listen-address=":9100"），如下所示：

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

它仍然不起作用。像这样的错误：

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"

如何更改端口？

以下配置有效：

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
