kubermetrics pods start failed with "exec format error"

[HeLiangHIT]

I am installing kubermetrics on CentOS Linux release 7.7.1908(x86_64, Intel(R) Xeon(R) CPU E5-2690) by the following cmd: kubectl apply -f manifests With prometheus and grafana running:

$ kubectl get pods --namespace=monitoring
NAME                                     READY   STATUS    RESTARTS   AGE
grafana-6d855fdbd6-w2hg4                 1/1     Running   0          15m
prometheus-deployment-599bbd9457-l5q2g   1/1     Running   0          15m
$ kubectl port-forward grafana-6d855fdbd6-w2hg4 --namespace=monitoring 3000:3000

Hello HeLiangHIT,

I wanted to thank you for giving Kubermetrics a shot in this early stage of it's lifespan. From what I'm seeing here is a compatibility issue of the Kubermetrics deployment alongside the Linux installation of Kubernetes.

Could you provide some details on what process you used to install Kubernetes itself (such as Kind or Minikube)

There is a good chance we will need to tweak something in the codebase to allow for Linux compatibility.

Once again thank you for trying out our product and we look forward to getting it up and running for you!

Hey guys!

I've got the same problem. I'm trying to deploy on GKE.

It's a test environment, but it's up to date and with other things running.

Is it something similar to that? here

Hello!

I have the same issue. I'm trying to deploy the tool on minikube.

Same issue running with k3s.

Thanks so much for the valuable feedback!

This is definitely a compatibility issue on our end and will be the prime focus of our next update! Thank you all for giving Kubermetrics a shot and I look forward to having you all try out our product on the next update!

Found that if I build the image on my mac and change the Service to the following:

apiVersion: v1
kind: Service
metadata:
  name: kubermetrics-srv
  labels:
    prometheus: cluster-monitoring
    k8s-app: kube-state-metrics
spec:
  selector:
    app: kubermetrics
  type: ClusterIP
  ports:
    - name: kubermetrics
      protocol: TCP
      port: 3080
      targetPort: 3068

I can port forward then and see the UI. It's empty with no info but it runs at that point. Not sure what the mechanism is to hook the pod into the cluster's info.

Any update on this?
