Installation Guide - Bare Metal Deployment
==========================================
----------------------------
1a. If your Jump Host does not have CentOS 7 already on it, or you would like
- to do a fresh install, then download the Apex bootable ISO from the OPNFV
- artifacts site <http://artifacts.opnfv.org/apex.html>. There have been
- isolated reports of problems with the ISO having trouble completing
- installation successfully. In the unexpected event the ISO does not work
- please workaround this by downloading the CentOS 7 DVD and performing a
+ to do a fresh install, then download the CentOS 7 DVD and perform a
"Virtualization Host" install. If you perform a "Minimal Install" or
install type other than "Virtualization Host" simply run
``sudo yum -y groupinstall "Virtualization Host"``
Replace /dev/sdX with the device assigned to your usb drive. Then select
the USB device as the boot media on your Jump Host

+2a. Install these repos:
- ``sudo yum install https://repos.fedorapeople.org/repos/openstack/openstack-ocata/rdo-release-ocata-3.noarch.rpm``
+ ``sudo yum install https://repos.fedorapeople.org/repos/openstack/openstack-queens/rdo-release-queens-1.noarch.rpm``
``sudo yum install epel-release``

The RDO Project release repository is needed to install OpenVSwitch, which
is a dependency of opnfv-apex. If you do not have external connectivity to
opnfv-apex repo hosts all of the Apex dependencies which will automatically
be installed when installing RPMs, but will be pre-installed with the ISO.
-2b. If you chose not to use the Apex ISO, then you must download and install
- the Apex RPMs to the Jump Host. Download the first 3 Apex RPMs from the
- OPNFV downloads page, under the TripleO RPMs

The following RPMs are available for installation:

- - opnfv-apex-undercloud - (reqed) Undercloud Image
- python34-opnfv-apex - (reqed) OPNFV Apex Python package

3. Edit the following values for each node:
network_settings.yaml allows you to customize your networking topology.
Note it can also be useful to run the command with the ``--debug``
argument which will enable a root login on the overcloud nodes with
- password: 'opnfv-apex'. It is also useful in some cases to surround the
+ password: 'opnfvapex'. It is also useful in some cases to surround the
deploy command with ``nohup``. For example:
``nohup <deploy command> &``, will allow a deployment to continue even if
ssh access to the Jump Host is lost during deployment.
3. When the deployment is complete the undercloud IP and overcloud dashboard
url will be printed. OPNFV has now been deployed using Apex.
