I was trying to install Prometheus Operator in DOKS using Helm. I used this tutorial: How to Set Up DigitalOcean Kubernetes Cluster Monitoring with Helm and Prometheus Operator

During installation helm chart I got error that cannot create CRD. Then I uninstalled the chart and executed command from section Helm fails to create CRDs from Prometheus-operator chart github page and then installed helm chart. I got error about connection timeout and whole cluster broke down. I cannot connect to it. After 45 minutes master node got alive and I deleted chart.

I was looking for solution and found this: Helm 3.0.2 dry-run + stable/prometheus-operator? Is this supposed to work? (I am using Helm 3) but again whole cluster broke down and after several hours still not working.

I presume that this kind of situation is related to DigitalOcean implementation but I am not sure.
