Single node deployment: Installing Kaspersky Next XDR Expert

If necessary, you can perform the single node deployment of Kaspersky Next XDR Expert so that the solution requires fewer computing resources (for example, for demonstration purposes).

In this configuration, the administrator host is used to install and manage the Kubernetes cluster and Kaspersky Next XDR Expert, as with distributed deployment. KDT is launched from the administrator host.

One target host, which acts as the primary and worker nodes, manages the Kubernetes cluster, stores metadata, and performs the workload of the Kaspersky Next XDR Expert components. The Kubernetes cluster and Kaspersky Next XDR Expert components are installed on this target host. Only the target host is included in the Kubernetes cluster (the primary worker node of the cluster).

To perform the single node deployment of Kaspersky Next XDR Expert:

1. Download the distribution package that has the Kaspersky Next XDR Expert components.
2. Install a database management system.

   Skip this step if you want to install the DBMS inside the cluster. KDT will install the DBMS during the Kaspersky Next XDR Expert deployment. In this case, the Kaspersky Next XDR Expert components and the DBMS will use one target host.

   Alternatively, you can install the DBMS on a separate server outside the cluster.

3. Prepare the administrator and target hosts, as with distributed deployment.

   Make sure that the hardware and software on the target host meet the requirements for the single node deployment.

   For the target host that acts as a primary worker node, perform all preparatory steps necessary for both primary and worker nodes.

4. Prepare the KUMA target hosts for installation of the KUMA services.
5. Prepare the KUMA inventory file.
6. Fill out the configuration file manually or by using the Configuration wizard.

   The deployment method (distributed deployment or single node deployment) is determined by the installation parameters. The following installation parameters are specific to the single node deployment: type, lowResources, vault_replicas, vault_ha_mode, vault_standalone, defaultClassReplicaCount.

7. Install Kaspersky Next XDR Expert by using KDT.

The Kubernetes cluster and Kaspersky Next XDR Expert components are deployed on the primary worker node, and the KUMA services are installed.
