# Building the ceph-grafana container image
From Nautilus onwards, grafana is embedded into the mgr/dashboard UI and uses two discrete grafana plugins to provide visualisations within the UI. To better support disconnected installs, and provide a more tested configuration you may use the Makefile, in this directory, to (re)generate the grafana containers based on each Ceph release.

The versions of grafana, and the plugins are defined in the script so testing can be done against a known configuration.  

## Container
The current implementation uses buildah with a CentOS8 base image. 

## Dependencies
Ensure you have the following dependencies installed on your system, before attempting to build the image(s)
- podman or docker
- buildah  
- jq
- make

## Build Process
The Makefile supports the following invocations;
```
# make                         <-- create container with dashboards from master 
# make all
# make ceph_version=octopus
# make ceph_version=nautilus
```

Once complete, a ```make all``` execution will provide the following containers on your system.
```
# podman images
