Cluster Configuration Overview

In the cluster provision process, when you select a release channel, you can choose to enable or disable the cluster features and protocols based on your requirements. You can also click the “Add optional custom configuration” to set custom cluster settings for your Pulsar cluster.

After cluster is provisioned, you can view the current cluster configuration through the “Configuration” page of your Pulsar cluster. You can also update the cluster configuration by clicking the “Edit Cluster” button at the top right corner of the page. You will be redirected to the same configuration page you see in the provision process, where you can make the desired changes to the configuration options.

To update the cluster configuration using snctl:

1. Ensure you have the latest version of snctl installed and configured.

2. Update the PulsarCluster CRD file (e.g., <cluster-name>.yaml) with the desired configuration options.

   Copy

   apiVersion: pulsar.streamnative.cloud/v1beta1
   kind: PulsarCluster
   metadata:
     name: <cluster-name>
   spec:
     config:
       # Add your desired configuration options here
       functionEnabled: true
       transactionEnabled: true
       <...>
   

3. Apply the updated PulsarCluster CRD file to the cluster:

   Copy

   Ask AI

   snctl apply -f <cluster-name>.yaml
   

To view the cluster configuration, you can use the following command:

snctl get pulsarcluster <cluster-name> -o yaml

To update the cluster configuration using the StreamNative Terraform Provider:

1. Ensure you have the StreamNative Terraform Provider configured in your environment.

2. Use the streamnative_pulsar_cluster resource to define or update your cluster configuration.

3. Specify the desired configuration options within the config block.

Here’s an example of how to update the cluster configuration using Terraform:

resource "streamnative_pulsar_cluster" "example" {
  name = "example"
  config {
    websocket_enabled = true
    transaction_enabled = true
    <...>
  }
}

To apply the changes, run the following command:

terraform apply

To view the cluster configuration, you can use the following command:

terraform show
