KAAP chart

Kaap manages Apache Pulsar clusters guided by a single CRD, called PulsarCluster.

Installation

Import the repository and install the operator:

helm repo add kaap https://datastax.github.io/kaap
helm repo update
helm install kaap kaap/kaap 

Usage

Install a PulsarCluster resource.

helm upgrade kaap kaap/kaap -f helm/examples/grafana/values.yaml

Wait for the cluster to be up and running

kubectl wait pulsar pulsar-cluster --for condition=Ready=True --timeout=240s

Uninstall the operator and the PulsarCluster

helm uninstall kaap

Upgrading to newer version

Since now the CRDs are in version v1alpha1 you need to replace them when they change. Note this is only needed in the early stages of the project.

kubectl replace -f helm/kaap/crds

Now you can proceed with the upgrade of the operator.

Configure the operator

The operator implementation is based on Quarkus. To configure the operator you can modify the operator.config section.

operator:
    config:
        logLevel: info|debug|trace
        quarkus: {}
        operator: {}

• The logLevel is referred only to the operator logs.

• The quarkus section is used to configure the Quarkus runtime. For instance, it might be useful to edit the Quarkus Operator SDK configuration. For more info see the Quarkus Operator SDK documentation. The proper format is explained in Quarkus Configuration Reference.

• The operator section is used to configure the operator itself.

    operator:
        config:
            operator:
                reconciliationRescheduleSeconds: 10
  

Configuration property	Type	Default	Description
reconciliationRescheduleSeconds	int	5	The number of seconds to wait before rescheduling a reconciliation while waiting for resources to be ready.
