Prometheus

Install/upgrade/uninstall Prometheus

If you have not already done so, make sure your cluster meets the package prerequisites. Be sure to refer to the troubleshooting guide in the event of a problem.

Important

Starting at eksctl anywhere version v0.12.0, packages on workload clusters are remotely managed by the management cluster.
While following this guide to install packages on a workload cluster, please make sure the kubeconfig is pointing to the management cluster that was used to create the workload cluster. The only exception is the kubectl create namespace command below, which should be run with kubeconfig pointing to the workload cluster.

Install

Generate the package configuration

eksctl anywhere generate package prometheus --cluster <cluster-name> > prometheus.yaml

Add the desired configuration to prometheus.yaml

Please see complete configuration options for all configuration options and their default values.

Example package file with default configuration, which enables prometheus-server and node-exporter:

 apiVersion: packages.eks.amazonaws.com/v1alpha1
 kind: Package
 metadata:
   name: generated-prometheus
   namespace: eksa-packages-<cluster-name>
 spec:
   packageName: prometheus

Example package file with prometheus-server (or node-exporter) disabled:

 apiVersion: packages.eks.amazonaws.com/v1alpha1
 kind: Package
 metadata:
   name: generated-prometheus
   namespace: eksa-packages-<cluster-name>
 spec:
   packageName: prometheus
   config: |
     # disable prometheus-server
     server:
       enabled: false
     # or disable node-exporter
     # nodeExporter:
     #   enabled: false

Example package file with prometheus-server deployed as a statefulSet with replicaCount 2, and set scrape config to collect Prometheus-server’s own metrics only:

 apiVersion: packages.eks.amazonaws.com/v1alpha1
 kind: Package
 metadata:
   name: generated-prometheus
   namespace: eksa-packages-<cluster-name>
 spec:
   packageName: prometheus
   targetNamespace: observability
   config: |
     server:
       replicaCount: 2
       statefulSet:
         enabled: true
     serverFiles:
       prometheus.yml:
         scrape_configs:
           - job_name: prometheus
             static_configs:
               - targets:
                 - localhost:9090

Create the namespace (If overriding targetNamespace, change observability to the value of targetNamespace)
```
kubectl create namespace observability
```

Install prometheus

eksctl anywhere create packages -f prometheus.yaml

Validate the installation

eksctl anywhere get packages --cluster <cluster-name>

Example command output

Update

To update package configuration, update prometheus.yaml file, and run the following command:

eksctl anywhere apply package -f prometheus.yaml

Upgrade

Prometheus will automatically be upgraded when a new bundle is activated.

Uninstall

To uninstall Prometheus, simply delete the package

eksctl anywhere delete package --cluster <cluster-name> generated-prometheus
