You can use the CLI installer to perform a silent deployment of a vCenter Server appliance on an ESXi host or vCenter Server instance.

The CLI deployment process includes downloading the vCenter Server installer on a network virtual machine or physical server from which you want to perform the deployment, preparing a JSON configuration file with the deployment information, and running the deployment command.

Important: The user name that you use to log in to the machine from which you want to run the CLI installer, the path to the vCenter Server installer, the path to your JSON configuration file, and the string values in your JSON configuration file, including the passwords, must contain only ASCII characters. Extended ASCII and non-ASCII characters are unsupported.

The vCenter Server appliance ISO file contains templates of JSON files that contain the minimum configuration parameters that are required for deploying the vCenter Server appliance. For information about preparing JSON templates for CLI deployment, see Prepare Your JSON Configuration File for CLI Deployment.
