Cluster Setup

We are going to need a StreamNative Cloud cluster for our client application to operate with. This guide can help you create your first StreamNative Cloud cluster.

Create a StreamNative Cloud cluster

From within the StreamNative Cloud console, creating a new cluster is just a few clicks.

  1. In the upper-right corner of the StreamNative Cloud Console, click your Profile and select Organizations to list your created organizations.

  2. Click the name of your first organization. In the figure below, the organization name is Demos.

  3. On the Select an Instance card of the Organization Dashboard page, click the + button.

  4. On the Choose the deployment type for your instance, click Deploy Serverless to start the instance creation process.

  5. On the Instance Configuration page, enter a name for your instance, and select a Cloud Provider. The instance name starts with a lowercase letter, contains any combination of lowercase letters (a-z), numbers (0-9), and hyphens (-), and must be 4-10 characters.

  6. Click Cluster Location to start the cluster creation process.

  7. On the Cluster Location page, enter a name for your cluster, select the cluster location, and then click Finish. The cluster name starts with a lowercase letter, contains any combination of lowercase letters (a-z), numbers (0-9), and hyphens (-), and must be 4-10 characters.

The cluster page appears, displaying the cluster creation process. Depending on the chosen cloud provider and other settings, it may take a few seconds to several minutes to provision the cluster. Once the cluster has been provisioned, the Cluster Dashboard page will be displayed.

Now you can get started configuring apps and data on your new cluster.

Get the cluster service URLs

Next, you'll need to get your StreamNative Cloud cluster's Service URLs to configure your client applications. These URLs allow your applications to connect to and interact with your cluster.

Your cluster provides different Service URLs depending on which protocol you plan to use:

For Pulsar Protocol:

  • Broker Service URL: Used to configure Pulsar clients to connect to the brokers for producing and consuming messages
  • HTTP Service URL: Used for administrative operations via the Pulsar admin API

For Kafka Protocol:

  • Kafka Service URL: Used as bootstrap servers in Kafka client configurations
  • Schema Registry URL: Used to configure Kafka serializers and deserializers that work with schemas

You'll need these URLs in the upcoming steps when setting up your producer and consumer clients.

To get the service URL(s) of a StreamNative cluster, follow these steps.

  1. Navigate to the Cluster Dashboard page by switching to the cluster workspace.

  2. On the Cluster Dashboard page, click Details tab.

  3. You will see the available service URLs in the Access Points area.

  4. You can click Copy at the end of the row of the service URL that you want to use.

Create a service account and API key

Next, to connect your client application to your cluster to produce and consume messages, you need to create a Service Account and choose an authentication mechanism: either API Key or OAuth.

API Key authentication is quicker to implement since you only need to create an API key in StreamNative Cloud. This guide uses API Key authentication.

  1. In the upper-right corner of the StreamNative Cloud Console, click your Profile and select Accounts & Accesses.

  2. On the left navigation pane, click Service Accounts.

  3. On the Service Account page, click + New.

  4. On the Create Service Account dialog, enter a name for the service account, and then click Confirm.

  5. On the Service Account page, in the row of the service account you just created, click the ... icon, and select Create API Key in the dropdown menu.

  6. On the New API Key dialog:

    • Enter a name for the API key
    • Set the expiration date
    • Select the instance you created in Step 2
    • Write a description for the API key
    • Click Confirm

    Note

    An API key and associated secret apply to the active StreamNative instance. If you add a new instance, you must create a new API key for producers and consumers on the new Pulsar instance. For more information, see Use API Keys to Authenticate to StreamNative Cloud.

  7. After the API key is created, you can see the API key shown in the New API Key dialog. Click the Copy and close button to copy the API key to your clipboard. Please note that you cannot retrieve the API key later after closing the dialog.

Note the API key as we will use them when configuring the producer and consumer clients in upcoming steps.
