Grafana Docker Image for use with Red Hat OpenShift

Grafana Docker Image for use with Red Hat OpenShift

This repository builds a docker image for use with Red Hat OpenShift taking into account security considerations for running on OpenShift - e.g. not running under the root user.

1. To build:

   docker build . -t wkulhanek/grafana:latest
   docker push wkulhanek/grafana:latest

   The repository includes an OpenShift Template to run Grafana with persistent storage.

2. To deploy:

   oc new-project grafana --display-name="Monitoring - Grafana Dashboards"
   oc new-app -f grafana -p VOLUME_CAPACITY=4Gi

   • Log into Grafana using the Route provided in the Template and using default account admin with password admin (maybe it would be a good idea to change the password after this…​).

3. Grafana Data Source

   • The Grafana template automatically provisions a Prometheus data source DS-Prometheus which connects to http://prometheus:9090 via proxy connection.

   • This works if there is a Prometheus (called prometheus) in the same project as Grafana. If this is not the case it is necessary to edit the datasource to point to another location.

4. Grafana Dashboard

   • The Grafana template automatically provisions a rudimentary OpenShift metrics dashboard. This dashboard is by no means comprehensive but could be used as a starting point for further customization.

   • The configured dashboard depends on metrics that are being collected by Prometheus as configured in https://github.com/wkulhanek/openshift-prometheus.

   • There are more example dashboards available at https://grafana.com/dashboards?search=kubernetes.

Prometheus behind oauth-proxy

Connection made to prometheus behind a proxy (https) are not working even if the app is in the same namespace.
Can this be fixed?
