Prometheus

Setup Prometheus in your Kubernetes Cluster

Instructions

NFS Volume

• Let's begin by provisioning an NFS default StoregeClass called monitoring-tools for the monitoring-tools Namespace.
• Run the nfs-monitoring-tools-storage-class helm installation.

Create the Persistent Volume

• Create the persistent volume and add the flag --wait=true to ensure that the claim is made after the deployment is complete.

kubectl apply -f pvc-prometheus.yaml --wait=true

Grant access to your Prometheus

• Run the access-prometheus.yaml to provide ClusterRoleBinding, ClusterRole and ServiceAccount.

kubectl apply -f access-prometheus.yaml

Run the Deployment

• Run the deployment-prometheus.yaml to deploy Prometheus, the Service and ConfigMap.

kubectl apply -f deployment-prometheus.yaml

Add the exporter kube-state-metrics

• Finally, from exporters directory, add the exporter and query the NODE_IP:32002

kubectl apply -f exporter-prometheus-kube-state-metrics.yaml

• If all snapped in place your Prometheus is running on your worker-node_IP:32002
• Additionally, query worker/mater-node_IP:32002/targets and worker-node_IP:32002/metrics.
