How to setup kafka through pulumi on kubernetes cluster

Hi, I’ve followed simple tutorial for creating K8S cluster on DO with Pulumi, but now I like to configure kafka provider from Pulumi on to the same cluster previously created.

I’m not sure how to achieve and if is possible to do it in simple manner, without extra scripts or manual editing of different kafka files.

So far, I have this code:


const kafkaProvider = new kafka.Provider(kafkaProviderName, {
  bootstrapServers: ["x.x.x.x:9092"],
}, { provider: kubernetesProvider });

export const topic = new kafka.Topic('demo-topic', {
  replicationFactor: 1,
  partitions: 1,
}, { provider: kafkaProvider });

export { kafkaProvider };

The Kafka provider creates resources within an existing Kafka cluster. Your example would create a new Topic by connecting to a Kafka cluster on that given IP and port.

If I understand correctly, you have a clean K8s cluster without Kafka installed on it yet. If so, you need to define another set of resources to provision a Kafka cluster on your K8s cluster.

Unfortunately, I don’t have an ready-to-use example of a Kafka installation. I suspect you may want to use a Helm chart for that. If so, this example shows how to provision a Helm chart with Pulumi: https://github.com/pulumi/examples/tree/master/kubernetes-ts-helm-wordpress
