We use Rancher v 2.0.2 as an administration platform for all our K8S clusters.
Our GitLab version is 11.1.4-ee (d17962f9) and is running on a VM in VMWare.
The way I deployed is like we did together in the Zoom meeting, integrate project with an existing Kubernetes cluster (same datacenter). I can install Tiller and Prometheus using the ‘Install’ button from the UI but when going to the ‘Operations/Metrics’ page after a couple of minutes there is an error in the UI ‘There was an error retrieving metrics’.
