When I enable the alertmanager a secret gets created with name alertmanager-{chartName}-alertmanager. But no pods or statefulset of alertmanager gets created.
When I delete this secret with kubectl delete and upgrade the chart again, then new secrets get created alertmanager-{chartName}-alertmanager , alertmanager-{chartName}-alertmanager-generated. In this case i can see the pods and statefulset of alertmanager. But the -generated secret has default values which are null. This secret alertmanager-{chartName}-alertmanager has updated configuration.
Checked the alertmanager.yml with amtool and it shows valid.
Chart - kube-prometheus-stack-36.2.0
