This is my prometheus.yml file and i create configmap using kubectl create configmap prometheus-server-config --from-file=prometheus.yml

But whenever i am creating the deployment using kubectl create -f deployment-prometheus.yaml
the pod status displays CrashLoopBackOff. I went through prometheus-kubernetes example and i'm running my cluster in minikube. What should be the cause of this?
Oneliner
kubectl apply --filename https://raw.githubusercontent.com/giantswarm/kubernetes-prometheus/master/manifests-all.yaml
Pre-Requisite
kubectl create namespace monitoring

I am running the cluster on AWS, the following tutorials work for me https://itnext.io/kubernetes-monitoring-with-prometheus-in-15-minutes-8e54d1de2e13. Let see if you can adapt it. Basicallly, I used helm to install coreos/kube-prometheus
.
# initialize tiller account kubectl create serviceaccount -n kube-system tiller kubectl create clusterrolebinding tiller-binding --clusterrole=cluster-admin --serviceaccount kube-system:tiller helm init --service-account tiller # install Prometheus app sleep 1m helm repo add coreos https://s3-eu-west-1.amazonaws.com/coreos-charts/stable/ helm install coreos/prometheus-operator --name prometheus-operator --namespace monitoring helm install coreos/kube-prometheus --name kube-prometheus --namespace monitoring --set global.rbacEnable=true --set prometheus.resources.requests.memory=300Mi # forward ports kubectl port-forward -n monitoring prometheus-kube-prometheus-0 9090 & kubectl port-forward $(kubectl get pods --selector=app=kube-prometheus-grafana -n monitoring --output=jsonpath="{.items..metadata.name}") -n monitoring 3000 & kubectl port-forward -n monitoring alertmanager-kube-prometheus-0 9093 &
