[Auggie321]

root@centos1 ~/kube-prometheus/manifests (main) $ kubectl apply -f prometheus-prometheus.yaml -f alertmanager-alertmanager.yaml 

error validating "prometheus-prometheus.yaml": error validating data: ValidationError(Prometheus.spec): 
unknown field "terminationGracePeriodSeconds" in com.coreos.monitoring.v1.Prometheus.spec; 
if you choose to ignore these errors, turn validation off with --validate=false

error validating "alertmanager-alertmanager.yaml": error validating data: ValidationError(Alertmanager.spec): 
unknown field "terminationGracePeriodSeconds" in com.coreos.monitoring.v1.Alertmanager.spec; 
if you choose to ignore these errors, turn validation off with --validate=false

i could use kubectl edit -n monitoring statefulset alertmanager-main/prometheus-k8s;

kubectl explain Prometheus --recursive > 123explain.yaml ##kubectl command output explain about kind: Prometheus
egrep terminationGracePeriodSeconds -r 123.explain.yaml ## got nothing with terminationGracePeriodSeconds's info
