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 create -f grafana.yaml
oc new-app grafana -p VOLUME_CAPACITY=4Gi

Configure a Grafana Data Source
- 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…).
- On the Home Dashboard click Add data source
- Use the following values for the datasource Config:
  - Name: DS-Prometheus
  - Type: Prometheus
  - Url: http://prometheus:9090 (if your Prometheus service is called prometheus and is in the same project)
  - Access: proxy
- Click Add
- Click Save & Test. You should see a message that the data source is working.
Configure a Grafana Dashboard
- There is an example dashboard JSON file openshift-metrics-dashboard.json available in the repository. This 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.
- In Grafana select the Icon on the top left and then select Dashboards / Import.
- Either copy/paste the contents of the JSON File (make sure to keep the correct formatting) or click the Upload .json File button selecting the .json file.
- In the next dialog enter OpenShift as the name and select the previously created datasource DS-Prometheus for Prometheus.
- Click Import
