Does anyone have any advice on which prometheus deployment method to use? Per prometheus-operator, there are many options(Prometheus Operator vs. kube-prometheus vs. community helm chart) Which one to use?

I had a big play last month about that. What I setup at the end with this. I install the operator operator hub I install prometheus using operator hub crd I didn't want to use helm and wanted to standardize my component using crd https://operatorhub.io/operator/prometheus

thanks @limited-knife-15571, looks interesting, please share

Previously I've used the helm chart for it and prometheus adapter. I didn't know about operator hub.

I finally got it working properly with kube-prometheus with a custom namespace and servicemonitor, not too complicated but definitely not plug-and-play with a custom namespace
