# Grafana Charm

## Description

This is the Grafana charm for Kubernetes using the Operator Framework.

## Usage

Initial setup (ensure microk8s is a clean slate with `microk8s.reset` or a fresh install with `snap install microk8s --classic`:

```bash

microk8s.enable dns storage registry dashboard

juju bootstrap microk8s mk8s

juju add-model lma

juju create-storage-pool operator-storage kubernetes storage-class=microk8s-hostpath

```

Deploy Grafana on its own:

```bash

git clone git@github.com:canonical/grafana-operator.git

cd grafana-operator

charmcraft build

juju deploy ./grafana.charm --resource grafana-image=grafana/grafana:7.2.1

```

View the dashboard in a browser:

1. `juju status` to check the IP of the of the running Grafana application

2. Navigate to `http://IP_ADDRESS:3000`

3. Log in with the default credentials username=admin, password=admin.

Add Prometheus as a datasource:

```bash

git clone git@github.com:canonical/prometheus-operator.git

cd prometheus-operator

charmcraft build

juju deploy ./prometheus.charm

juju add-relation grafana prometheus

watch -c juju status --color  # wait for things to settle down

```

> Once the deployed charm and relation settles, you should be able to see Prometheus data propagating to the Grafana dashboard.

### High Availability Grafana

This charm is written to support a high-availability Grafana cluster, but a database relation is required (MySQL or Postgresql).

If HA is not required, there is no need to add a database relation.

> NOTE: HA should not be considered for production use.

and install the development requirements,

    virtualenv -p python3 venv

    source venv/bin/activate

    pip install -r requirements-dev.txt

## Testing

Just run `run_tests`:

    ./run_tests
