Flagger Grafana

Grafana dashboards for monitoring progressive deployments powered by Flagger and Prometheus.

Prerequisites

• Kubernetes >= 1.11
• Prometheus >= 2.6

Installing the Chart

Add Flagger Helm repository:

helm repo add flagger https://flagger.app

To install the chart for Istio run:

helm upgrade -i flagger-grafana flagger/grafana \
--namespace=istio-system \
--set url=http://prometheus:9090

To install the chart for AWS App Mesh run:

helm upgrade -i flagger-grafana flagger/grafana \
--namespace=appmesh-system \
--set url=http://appmesh-prometheus:9090

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

Uninstalling the Chart

To uninstall/delete the flagger-grafana deployment:

helm delete --purge flagger-grafana

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

Configuration

The following tables lists the configurable parameters of the Grafana chart and their default values.

Parameter	Description	Default
image.repository	Image repository	grafana/grafana
image.pullPolicy	Image pull policy	IfNotPresent
image.tag	Image tag	<VERSION>
replicaCount	desired number of pods	1
resources	pod resources	none
tolerations	List of node taints to tolerate	[]
affinity	node/pod affinities	node
nodeSelector	node labels for pod assignment	{}
service.type	type of service	ClusterIP
url	Prometheus URL	http://prometheus:9090

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

helm install flagger/grafana --name flagger-grafana \
--set token=WEAVE-CLOUD-TOKEN

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

helm install flagger/grafana --name flagger-grafana -f values.yaml

Tip: You can use the default values.yaml
