Grafana Charm
Description
This is the Grafana charm for Kubernetes using the Operator Framework. It is under active development and should not yet be considered for production use.
Usage
Initial setup (ensure microk8s is a clean slate with microk8s.reset or a fresh install with snap install microk8s --classic:
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:
git clone git@github.com:canonical/grafana-operator.git
cd grafana-operator
charmcraft build
juju deploy ./grafana.charm
View the dashboard in a browser:
juju statusto check the IP of the of the running Grafana application- Navigate to
http://IP_ADDRESS:3000 - Log in with the default credentials username=admin, password=admin.
Add Prometheus as a datasource:
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: Consider HA to be in an alpha release.
