Create a Core Instance

TELEMETRY PIPELINE

After you've installed a Core Operator in your Kubernetes cluster or Linux environment, you'll need to create at least one Core Instance in that environment before deploying any pipelines.

Create a new Core Instance

You can use Pipeline CLI or Helm to create a Core Instance. For best results, use the same method that you used to install the associated Core Operator.

Pipeline CLI commands and flags are identical regardless of whether your Core Operator is in a Kubernetes cluster or in a Linux environment. However, if you're creating a Core Instance in a Linux environment, you'll need to set your Linux environment variables before proceeding.

Run the following command to create a new Core Instance:
```
calyptia create core_instance operator --name INSTANCE
```
Replace INSTANCE with the name you'd like to give your new Core Instance.

To create your Core Instance in a specific namespace, add the --kube-namespace NAMESPACE flag, and replace NAMESPACE with the namespace where you'd like to create the Core Instance.

If you're using custom certificates or your own certificate authority, add the --no-tls-verify flag.
Repeat this command to create additional Core Instances as necessary. You must create at least one Core Instance in each of the Kubernetes clusters or Linux environments where you installed a Core Operator. Optionally, you can also create multiple Core Instances in any of those clusters or environments.

Next steps

After you've created a Core Instance, you can configure its behavior and begin to route telemetry data. Additionally, you can view and manage your Core Instances in the Telemetry Pipeline web interface (opens in a new tab).
