Preparing the target machine

To prepare the target machine for the installation of KUMA components:

1. Ensure that hardware, software, and installation requirements are met.
2. Specify the host name. We recommend specifying a FQDN. For example, kuma1.example.com.

   Do not change 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. Register the target machine in your organization's DNS zone to allow host names to be translated to IP addresses.

   The option of using the /etc/hosts file is not available when the Core is deployed in Kubernetes.

4. To get the hostname that you must specify when installing KUMA, run the following command and record the result:

   hostname -f

   The control machine must be able to access the target machine using this name.

The target machine is ready for the installation of KUMA components.
