Flagger Grafana
Grafana dashboards for monitoring progressive deployments powered by Istio, Prometheus and Flagger.
Prerequisites
- Kubernetes >= 1.11
- Istio >= 1.0
- Prometheus >= 2.6
Installing the Chart
Add Flagger Helm repository:
helm repo add flagger https://flagger.app
To install the chart with the release name flagger-grafana:
helm upgrade -i flagger-grafana flagger/grafana \
--namespace=istio-system \
--set url=http://prometheus:9090 \
--set user=admin \

The command deploys Grafana on the Kubernetes cluster in the default namespace. The configuration section lists the parameters that can be configured during installation.

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