# grafana-operator

[Grafana Operator](https://github.com/integr8ly/grafana-operator) is an Operator which introduces Lifecycle Management for Grafana Dashboards and Plugins.

## TL;DR

```console
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/grafana-operator
```

## Introduction

Bitnami charts for Helm are carefully engineered, actively maintained and are the quickest and easiest way to deploy containers on a Kubernetes cluster that are ready to handle production workloads.

This chart bootstraps a [Grafana Operator](https://github.com/integr8ly/grafana-operator/blob/master/documentation/deploy_grafana.md) Deployment [Kubernetes](https://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.

Bitnami charts can be used with [Kubeapps](https://kubeapps.com/) for deployment and management of Helm Charts in clusters. This Helm chart has been tested on top of [Bitnami Kubernetes Production Runtime](https://kubeprod.io/) (BKPR). Deploy BKPR to get automated TLS certificates, logging and monitoring for your applications.

## Prerequisites

- Kubernetes 1.19+
- Helm 3.2.0+

## Installing the Chart

To install the chart with the release name `my-release`:

```console
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/grafana-operator
```

These commands deploy grafana-operator on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation.

> **Tip**: List all releases using `helm list`

## Uninstalling the Chart

To uninstall/delete the `my-release` helm release:

```console
$ helm uninstall my-release
```

The command removes all the Kubernetes components associated with the chart and deletes the release.

## Differences between the Bitnami Grafana chart and the Bitnami Grafana Operator chart

The Bitnami catalog offers both the `bitnami/grafana` and `bitnami/grafana-operator` charts. Each solution covers different needs and use cases.

- The `bitnami/grafana` chart deploys a single Grafana installation (with Grafana Image Renderer) using a Kubernetes Deployment object (together with Services, PVCs, ConfigMaps, etc.). Its lifecycle is managed using Helm and, at the Grafana container level, the following operations are automated: persistence management, configuration based on environment variables and plugin initialization. The chart also allows deploying dashboards and data sources using ConfigMaps. The Deployments do not require any ServiceAccounts with special RBAC privileges so this solution would fit better in more restricted Kubernetes installations.

- The `bitnami/grafana-operator` chart deploys a Grafana Operator installation using a Kubernetes Deployment. The operator will extend the Kubernetes API with the following objects: `Grafana`, `GrafanaDashboard` and `GrafanaDataSource`. From that moment, the user will be able to deploy objects of these kinds and the previously deployed Operator will take care of deploying all the required Deployments, ConfigMaps and Services for running a Grafana instance. Its lifecycle is managed using _kubectl_ on the Grafana, GrafanaDashboard and GrafanaDataSource objects.

> Note: As the operator automatically deploys Grafana installations, the Grafana Operator pods will require a ServiceAccount with privileges to create and destroy multiple Kubernetes objects. This may be problematic for Kubernetes clusters with strict role-based access policies.

For more information, refer to the [documentation on the differences between these charts](https://docs.bitnami.com/kubernetes/infrastructure/grafana-operator/get-started/compare-solutions/), including more information on the differences in the deployment objects.

Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,

```console
$ helm install my-release \
  --set livenessProbe.successThreshold=5 \
    bitnami/grafana-operator
```

The above command sets the `livenessProbe.successThreshold` to `5`.

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

```bash
$ helm install my-release -f values.yaml bitnami/grafana-operator
```

## Configuration and installation details

### [Rolling vs Immutable tags](https://docs.bitnami.com/containers/how-to/understand-rolling-tags-containers/)

It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.

Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.

### Create Grafana Dashboards

After the installation, create Dashboards under a CRD of your Kubernetes cluster.

For more details regarding what is possible with those CRDs please have a look at [Working with Dashboards](https://github.com/integr8ly/grafana-operator/blob/master/documentation/dashboards.md).

### Deploy extra Grafana resources or objects

There are cases where you may want to deploy extra objects, such as custom _Grafana_, _GrafanaDashboard_ or _GrafanaDataSource_ objects. For covering this case, the chart allows adding the full specification of other objects using the `extraDeploy` parameter.

Refer to the documentation on deploying extra Grafana resources for an [example of deploying a custom Grafana definition](https://docs.bitnami.com/kubernetes/infrastructure/grafana-operator/configuration/deploy-extra-resources/) or to the [tutorial on managing multiple Grafana instances and dashboards on Kubernetes with the Grafana Operator](https://docs.bitnami.com/tutorials/manage-multiple-grafana-operator).

## Upgrading

```bash
$ helm upgrade my-release bitnami/grafana-operator
```

### To 2.0.0

In this version the CRDs get updated from v1beta to v1 stable API. It also updates the operator image to the new major `v4.x.y` release.

The `values.yaml` does not need changes when updating to this major version of the chart

- CRDs were updated to the latest Grafana Operator 4.0.x release artifacts:
  - The apiVersion of CRDs was updated from `apiextensions.k8s.io/v1beta1` to `apiextensions.k8s.io/v1`.
  - Kubernetes 1.16 or higher is now required.

Some of the chart values were changed to adapt to the latest Bitnami standards. More specifically:

- `operator.args` was replaced with the standard value of overriding the container commands. The original `operator.args` contents were moved to `operator`.
- Several standard values were added such as `sidecars`, `initContainers`, `extraEnvVars`, amongst others.

No issues should be expected when upgrading.

### To 1.0.0

In this version, the `image` block is defined once and is used in the different templates, while in the previous version, the `image` block was duplicated for the grafana container and the grafana plugin init one

```yaml
image:
  registry: docker.io
  repository: bitnami/grafana
  tag: 7.5.10
```

VS

```yaml
image:
  registry: docker.io
  repository: bitnami/grafana
  tag: 7.5.10
---
grafanaPluginInit:
  image:
    registry: docker.io
    repository: bitnami/grafana
    tag: 7.5.10
```
