Apache Flink Helm Chart

This is an implementation of

This chart will install session cluster If you are interested in supporting session/job clusters:

Pre Requisites:

  • Kubernetes 1.3 with alpha APIs enabled and support for storage classes

  • PV support on underlying infrastructure

  • Requires at least v2.0.0-beta.1 version of helm to support dependency management with requirements.yaml

StatefulSet Details

StatefulSet Caveats

Chart Details

This chart will do the following:

  • Implement a dynamically scalable Flink(Jobmanagers and Taskmanagers) cluster using Kubernetes StatefulSets

  • Implement a dynamically scalable zookeeper cluster as another Kubernetes StatefulSet required for the Flink cluster above

Installing the Chart

To install the chart with the release name my-flink in the default namespace:

$ helm repo add riskfocus
$ helm repo update
$ helm install --name my-flink riskfocus/flink

If using a dedicated namespace(recommended) then make sure the namespace exists with:

$ helm repo add riskfocus
$ helm repo update
$ helm install --name my-flink --namespace flink riskfocus/flink

This chart can includes a ZooKeeper chart as a dependency to the Flink cluster Jobmanagers HA mode in its requirement.yaml. The chart can be customized using the following configurable parameters(other parameters can be found in values.yaml):

Install with HA

You can install this chart with enabled HA based on Zookeeper by provided follow parameters:

$ helm install --name my-flink riskfoucs/flink --set \
