Data flow

Pre requisites

You need Kubernetes and Helm It has been tested with Docker For Windows, because it includes k8s as well.

Install

Release name is hard coded now (frx), because of Helm approach (hard to templating in parent chart's values.yaml). Installation of frx deployment:

$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm repo add lsmhun https://lsmhun.github.io/lsmhun-helm-charts/
$ helm dep update
$ helm install frx . --create-namespace -n frxns

Grafana interface is available through NodePort.

$ kubectl expose deployment frx --type=NodePort --name=frxgraf -n frxns 
$ kubectl describe service frxgraf -n frxns | grep NodePort:

Then you can visit the page: https://127.0.0.1: YOUR_NODE_PORT

Default username and password (admin/admin) is defined in values.yaml .

Uninstalling the Chart

To uninstall/delete the frx deployment:

$ helm delete frx -n frxns

The command removes all the Kubernetes components but PVC's associated with the chart and deletes the release.

To delete the PVC's associated with frx:

$ kubectl delete pvc -n frxns data-frx-kafka-0 data-frx-postgresql-0  data-frx-zookeeper-0

Note: Deleting the PVC's will delete postgresql data as well. Please be cautious before doing it.
