Unable to deploy emqx-exporter on Kubernetes

[roynilanjan]

Hi,

I am unable to run emqx-exporter on my Kind cluster.
I am following https://docs.emqx.com/en/emqx-operator/latest/tasks/configure-emqx-prometheus.html to deploy.

I have configured the following yaml with emqx-dashboard service name , api key and secret.

apiVersion: v1
kind: Service
metadata:
labels:
app: emqx-exporter
name: emqx-exporter-service
spec:
ports:
- name: metrics
port: 8085
targetPort: metrics
selector:
app: emqx-exporter

apiVersion: apps/v1
kind: Deployment
metadata:
name: emqx-exporter
labels:
app: emqx-exporter
spec:
selector:
matchLabels:
app: emqx-exporter
replicas: 1
template:
metadata:
labels:
app: emqx-exporter
spec:
securityContext:
runAsUser: 1000
containers:
- name: exporter
image: emqx-exporter:latest
imagePullPolicy: IfNotPresent
args:
# "emqx-dashboard-service-name" is the service name that creating by operator for exposing 18083 port
- --emqx.nodes=${emqx-dashboard-service-name}:18083
- --emqx.auth-username=${paste_your_new_api_key_here}
- --emqx.auth-password=${paste_your_new_secret_here}
securityContext:
allowPrivilegeEscalation: false
runAsNonRoot: true
ports:
- containerPort: 8085
name: metrics
protocol: TCP
resources:
limits:
cpu: 100m
memory: 100Mi
requests:
cpu: 100m
memory: 20Mi
After applying the yaml the pods are not coming in running state :

k logs pod/emqx-exporter-697f97866-zmvx6
emqx-exporter: error: unknown long flag '--emqx.nodes', try --help
royn2@W1164RNGY3:~$ k logs pod/emqx-exporter-7955d74bdb-9whrw
Error from server (BadRequest): container "exporter" in pod "emqx-exporter-7955d74bdb-9whrw" is waiting to start: trying and failing to pull image

EMQX operator doc wasn't updated

args with --emqx.nodes etc... was for version 0.1.x

Check this example: https://github.com/emqx/emqx-exporter/tree/main/examples/kubernetes if you want to use the latest version
