+:bulb: The above helm command is hard-coding the `loki` chart version to 5.48.0, since we only tested it with `loki` 2.9.6. `loki` 3.x charts (v6.0.x and up) have a breaking change, so if you would like to install `loki` 3.x please visit the [loki's official docs](https://grafana.com/docs/loki/latest/setup/install/helm/) and provide your own `loki-values.yaml`

 ```yaml
 * "loki" will be the service name, the url to access loki as a datasource can be visualised as http://<service_name>.<namespace>:<port>
       ex: http://loki.$INST_NAMESPACE:3100 will be the "loki_url" value
