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.

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.
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…).
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.
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.
