 This document describes how to build offline installer packages. The build process should be triggered on a host with internet connectivity. It will retrieve all artifacts required for ONAP deployment based on both - static data list files and dynamically assembled ones. The host used for the procedure in this guide should be preferably a separate build server.
 
-Procedure was completely tested on RHEL 7.6 as it’s the default target installation platform, however with small adaptations it should be applicable also for other platforms.
-Some discrepancies when Centos 7.6 is used are described below as well.

-We assume that procedure is executed on RHEL 7.6 server with \~300G disc space, 16G+ RAM and internet connectivity.

-As of now, the offline installer supports only **RHEL 7.x** and **CentOS 7.6** distributions, with at least *@core* and *@base* package groups installed including *Mandatory* and *Default* package sets. So, your VMs should be preinstalled with this operating system - the hypervisor and platform can be of your choosing.

 We will expect from now on that you installed four VMs and they are connected to the shared network. All VMs must be reachable from *install-server* (below), which can be the hypervisor, *infra-node* or completely different host. But in either of these cases the *install-server* must be able to connect over ssh to all of these nodes.
