+# 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
