Istio missing from Rancher UI Cluster Tools after installing Rancher Monitering

Rancher 2.x
1

Hi there, I’m facing an issue which leads to Istio disappearing from Cluster tools even in the local cluster which Rancher Server installed. I have seen the same issue from my prev installation, so I did reinstall Racher Server into a new EKS cluster. I did see istio available at first in the cluster tools of the local cluster after fresh installation. Then, I went head to create a new custom K8S cluster with RKE using EC2 computes, let’s called rke-dev. I did also see istio available in the rke-dev cluster at first. However, after I installed Monitoring into the rke-dev cluster, it happened again, the istio is disappearing from both rke-dev and local clusters! Has anyone know what the issue is?

FYI:
Rancher is in version v.2.6.5

  • local cluster:
    Provider: Amazon EKS
    Kubernetes Version: v1.22.6
  • rke-dev cluster:
    Provider: RKE
    Kubernetes Version: v1.23.rancher1-1

Thanks, Sang
