servicemonitor and argocd-image-updater service is not made by default

[yasharne]

Describe the bug I have installed argocd-image-updater based on this documents (first method): https://argocd-image-updater.readthedocs.io/en/stable/install/installation/#method-1-installing-as-kubernetes-workload-in-argo-cd-namespace But as metrics part says, there should be a services called argocd-image-updater which exposes metrics port but there are no service created with this method:

 kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj-labs/argocd-image-updater/stable/manifests/install.yaml
serviceaccount/argocd-image-updater unchanged
role.rbac.authorization.k8s.io/argocd-image-updater unchanged
rolebinding.rbac.authorization.k8s.io/argocd-image-updater unchanged
configmap/argocd-image-updater-config unchanged
configmap/argocd-image-updater-ssh-config unchanged
secret/argocd-image-updater-secret unchanged
deployment.apps/argocd-image-updater unchanged

To Reproduce Steps to reproduce the behavior: install with this command:

kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj-labs/argocd-image-updater/stable/manifests/install.yaml

Expected behavior create the service

Having the same issue.

For now, I managed to monitor the metrics by kustomizing the deployment to add the argument --metrics-port=8081 to the container.

Then, I added a service with port 8081 named metrics with a selector to point to the pod:

apiVersion: v1
kind: Service
metadata:
  name: argocd-image-updater
  labels:
    app.kubernetes.io/name: argocd-image-updater
spec:
  selector:
    app.kubernetes.io/name: argocd-image-updater
  ports:
    - protocol: TCP
      port: 8081
      name: metrics

The patch file is as follows (probably can be more concise):

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app.kubernetes.io/component: controller
    app.kubernetes.io/name: argocd-image-updater
