# Grafana Dashboards Configmap Generator
## Description:
Tool to maintain grafana dashboards' configmap for a grafana deployed with kube-prometheus (a tool inside prometheus-operator).
The tool reads the content of a directory with grafana .json resources (dashboards and datasources) and creates a manifest file under output/ directory with all the content from the files in a Kubernetes ConfigMap format.
Based on a configurable size limit, the tool will create 1 or N configmaps to allocate the .json resources (bin packing). If the limit is reached then the configmaps generated will have names like grafana-dashboards-0, grafana-dashboards-1, etc, and if the limit is not reached the configmap generated will be called "grafana-dashboards".
Input Parameters Allowed:
```bash
-i dir, --input-dir dir
Directory with grafana dashboards to process.
Important notes:
Files should be suffixed with -dashboard.json or -datasource.json.
We don't recommend file names with spaces.
-o file, --output-file file
Output file for config maps.
-s NUM, --size-limit NUM
Size limit in bytes for each dashboard (default: 240000)
-n namespace, --namespace namespace
Namespace for the configmap (default: monitoring).
-x, --apply-configmap
Applies the generated configmap with kubectl.
--apply-type
Type of kubectl command. Accepted values: apply, replace, create (default: apply).
```
## Usage
Just execute the .sh under bin/ directory. The output will be placed in the output/ directory.
Examples:
```bash
$ ./grafana_dashboards_generate.sh
$ bin/grafana_dashboards_generate.sh -o manifests/grafana/grafana-dashboards.yaml -i assets/grafana-dashboards
$ bin/grafana_dashboards_generate.sh -s 1000000 --apply-configmap --apply-type replace
# Note: the output file, if provided with -o, shouldn't exist.
```
## Configuration and options
* Put the json files you want to pack in the templates/grafana-dashboards/ directory
* Size limit default is 240000 bytes due to the annotations size limit in kubernetes of 256KB.
