Deprecated

The code is this repo is no longer actively maintained. For an alternative method of managing Grafana instances on OpenShift and Kubernetes, consider the Grafana Operator.

Automation of the data source and dashboard creation process for OpenShift clusters.

  • This script is written for Python 3.6.
  • The Python app is deployed using OpenShift's source to image (S2i) build process.
  • Entrypoint for the app is app.py

The purpose of this script is to automate the creation of dashboards and their respective data sources, for the number of OpenShift clusters which the customer has.

Prerequisites

  1. Have a Grafana instance deployed which has a route exposed as well as a API key generated.

  2. Ensure that the router IP of the cluster which this pod will be running in is whitelisted on the Grafana route in the destination cluster.

Deployment

  1. Create a new OpenShift project using the following command: oc new-project grafana-automation

  2. Create an OpenShift secret using the following command: oc create -f secret.yaml

Example secret.yaml:

apiVersion: v1
kind: Secret
metadata:
  name: customer-secret
type: Opaque
stringData:
  customer_clusters.yaml: |-
    ---
    Customers:
      CustomerA:
      - ClusterDataSourceUrl: https://cluster1.prometheus.com
        BasicAuthUsername: xxxxx
        BasicAuthPassword: xxxxx
      - ClusterDataSourceUrl: https://cluster2.prometheus.com
        BasicAuthUsername: xxxxx
        BasicAuthPassword: xxxxx
      CustomerB:
      - ClusterDataSourceUrl: https://cluster3.prometheus.com
        BasicAuthUsername: xxxxx
        BasicAuthPassword: xxxxx
      - ClusterDataSourceUrl: https://cluster4.prometheus.com
        BasicAuthUsername: xxxxx
        BasicAuthPassword: xxxxx
      - ClusterDataSourceUrl: https://cluster5.prometheus.com
        BasicAuthUsername: xxxxx
        BasicAuthPassword: xxxxx
  1. Deploy this app in OpenShift using the following command, replacing the variables as required.
secret=$(oc get secret customer-secret -o "jsonpath={.data['customer_clusters\.yaml']}" | base64 --decode) && oc new-app python:3.6~https://github.com/UKCloud/openshift-automation-grafana.git \
    -e DASHBOARD_SOURCES="$secret" \
    -e GRAFANA_API_TOKEN="insert_token_here" \
    -e GRAFANA_URL="https://grafana.yourcluster.com/"
