# Create a Core Instance

After you've [installed a Core Operator](/ingest/pipeline/v2/install/install-operator) in
your Kubernetes cluster or Linux environment, you'll need to create a
[Core Instance](/ingest/pipeline/v2/concepts#core-instance) in that
environment before deploying any pipelines.

<Note>
  If you used Pipeline CLI to install your Core Operator in a Kubernetes cluster,
  use Pipeline CLI to create a Core Instance. If you used Helm to install your
  Core Operator in a Kubernetes cluster, use Helm to create a Core Instance.

  If you installed your Core Operator in a Linux environment, use Pipeline CLI
  to create a Core Instance.

    1. If you're creating a Core Instance in a Linux environment, set your
       [Linux environment variables](/ingest/pipeline/v2/install/environment-variables).

    2. Run the following command to create a new Core Instance:

       ```shell theme={null}
       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](/ingest/pipeline/v2/configure/kubernetes/namespaces),
       add the `--kube-namespace NAMESPACE` flag, and replace *`NAMESPACE`* with the
       namespace where you want to create the Core Instance.

       If you're using custom certificates or your own certificate authority, add the
       `--no-tls-verify` flag.
  </Tab>

  <Tab title="Helm" id="create-helm">
    ```shell /INSTANCE/ /TOKEN/ theme={null}
    helm install core-instance calyptia/core-instance --set coreInstance=INSTANCE --set cloudToken=TOKEN
    ```

    Replace the following values:

    * *`INSTANCE`*: The name for your new Core Instance.
    * *`TOKEN`*: [Your API token](/ingest/pipeline/pipeline-cli/authenticate) to authenticate with
      the Telemetry Pipeline backend.
  </Tab>
</Tabs>

## Next steps

After you've created a Core Instance, you can [configure](/ingest/pipeline/v2/configure)
its behavior and begin to [create telemetry pipelines](/ingest/pipeline/v2/build/create-modify).
Additionally, you can view and manage your Core Instances in the
[Telemetry Pipeline web interface](https://core.calyptia.com/).
