Red Hat Install - Docker and Core Installation

OVERVIEW

The VersaVision software runs inside of a Docker environment.

Each Application runs inside of a specific Container on Docker.

In order to get the system running, we will need to install Docker and the Core Package on the Red Hat Computer/Server/VM

The user will need the IP Address of the Computer/Server/VM.

Verify with your IT Department that the IP Address assigned is either a Static IP or DHCP Reserved Address.

The guide below will explain how to install Docker and the Core Software Package.

REQUIREMENTS

Computer/Server/VM must be loaded with Red Hat 8 or 9.

IT must assign an Administrator level user name and password for VersaCall Installation/User.

Internet Access Required for the Installation process. Access can be removed after installation.

SSH Client is required if the User/Installer does not have physical access to the server.

Server/Computer/VM must have a Static IP Address or a DHCP Reserved IP Address.

The Core and Docker files must already be downloaded and uploaded to the Red Hat Computer/Server/VM.
