Preparing the hosts for installation of the KUMA services

The KUMA services (collectors, correlators, and storages) are installed on the KUMA target hosts that are located outside the Kubernetes cluster.

To prepare the KUMA target hosts for installation of the KUMA services:

1. Ensure that hardware, software, and installation requirements are met.
2. Specify the host names.

   We recommend specifying the FQDN, for example: kuma1.example.com.

   We do not recommend changing the KUMA host name after installation. This will make it impossible to verify the authenticity of certificates and will disrupt the network communication between the application components.

3. Configure the SSH connection between the administrator host and hosts on which the KUMA services will be installed.

   You can use the SSH keys created for the target hosts. Alternatively, you can generate new SSH keys by using the ssh-keygen utility:

   1. On the administrator host, generate SSH keys by using the ssh-keygen utility without a passphrase.
   2. Copy the public key to hosts on which the KUMA services will be installed by using the ssh-copy-id utility.
4. Register the KUMA target hosts in your organization's DNS zone to allow host names to be translated to IP addresses.
5. To get the hostname that you must specify in the KUMA inventory file, run the following command:

   hostname -f

   The prepared hosts must provide access for the administrator host by the hostname.

The hosts are ready for installation of the KUMA services.
