Deployment -options are put into the YAML file (``/etc/opnfv-apex/deploy_settings.yaml``). Networking -definitions gathered under section `Network Requirements`_ are put into the YAML file -(``/etc/opnfv-apex/network_settings.yaml``). ``opnfv-deploy`` will boot the Instack VM -and load the target deployment configuration into the provisioning toolchain.

The nodes will reboot and PXE again off the Instack PXE server to -provision each node using the Glance disk images provided by Instack. These disk images -include all the necessary packages and configuration for an OPNFV deployment to execute. -Once the node's disk images have been written to disk the nodes will boot off the newly written -disks and execute cloud-init which will execute the final node configuration. This -configuration is largly completed by executing a puppet apply on each node. - -Installation High-Level Overview - VM Deployment -================================================ - -The VM nodes deployment operates almost the same way as the bare metal deployment with a -few differences. ``opnfv-deploy`` still deploys an Instack VM. In addition to the Instack VM -a collection of VMs (3 control nodes + 2 compute for an HA deployment or 1 control node and -1 compute node for a Non-HA Deployment) will be defined for the target OPNFV deployment. -The part of the toolchain that executes IPMI power instructions calls into libvirt instead of -the IPMI interfaces on baremetal servers to operate the power managment. These VMs are then -provisioned with the same disk images and configuration that baremetal would be. - -To RDO Manager these nodes look like they have just built and registered the same way as -bare metal nodes, the main difference is the use of a libvirt driver for the power management. - -Installation Guide - Bare Metal Deployment -========================================== - -**WARNING: Baremetal documentation is not complete. WARNING: The main missing instructions are r elated to bridging -the networking for the undercloud to the physical underlay network for the overcloud to be deployed to.** - -This section goes step-by-step on how to correctly install and provision the OPNFV target -system to bare metal nodes. - -Install Bare Metal Jumphost ---------------------------- - -1a. If your Jumphost does not have CentOS 7 already on it, or you would like to do a fresh - install, then download the Apex bootable ISO from OPNFV artifacts <http://artifacts.opnfv.org/>. - -1b. If your Jump host already has CentOS 7 with libvirt running on it then install the - opnfv-apex RPM from OPNFV artifacts <http://artifacts.opnfv.org/>. - -2a. Boot the ISO off of a USB or other installation media and walk through installing OPNFV CentOS 7. - The ISO comes prepared to be written directly to a USB drive with dd as such: - - ``dd if=opnfv-apex.iso of=/dev/sdX bs=4M`` - - Replace /dev/sdX with the device assigned to your usb drive. Then select the USB device as the - boot media on your Jumphost - -2b. Install the RDO Release RPM and the opnfv-apex RPM: - - ``sudo yum install -y https://www.rdoproject.org/repos/rdo-release.rpm opnfv-apex-{version}.rpm`` - - 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 use this repository you need to download - the OpenVSwitch RPM from the RDO Project repositories and install it with the opnfv-apex RPM. - -3. After the operating system and the opnfv-apex RPM are installed, login to your Jumphost as root. - -4. Configure IP addresses on the interfaces that you have selected as your networks. - -5. Configure the IP gateway to the Internet either, preferably on the public interface. - -6. Configure your ``/etc/resolv.conf`` to point to a DNS server (8.8.8.8 is provided by Google). - -Creating a Node Inventory File ------------------------------- - -IPMI configuration information gathered in section `Execution Requirements (Bare Metal Only)`_ -needs to be added to the ``inventory.yaml`` file. - -1. Edit ``/etc/apex-opnfv/inventory.yaml``. - -2. The nodes dictionary contains a definition block for each baremetal host that will be deployed. - 1 or more compute nodes and 3 controller nodes are required. - (The example file contains blocks for each of these already). - It is optional at this point to add more compute nodes into the node list. - -3. Edit the following values for each node: - - - ``mac_address``: MAC of the interface that will PXE boot from Instack - - ``ipmi_ip``: IPMI IP Address - - ``ipmi_user``: IPMI username - - ``ipmi_password``: IPMI password - - ``ipmi_type``: Power Management driver to use for the node - - ``cpus``: (Introspected*) CPU cores available - - ``memory``: (Introspected*) Memory available in Mib - - ``disk``: (Introspected*) Disk space available in Gb - - ``arch``: (Introspected*) System architecture - - ``capabilities``: (Optional**) Intended node role (profile:control or profile:compute) - -* Introspection looks up the overcloud node's resources and overrides these value. You can -leave default values and Apex will get the correct values when it runs introspection on the nodes. - -** If capabilities profile is not specified then Apex will select node's roles in the OPNFV cluster -in a non-deterministic fashion. - -Creating the Settings Files ------------------------------------ - -Edit the 2 settings files in /etc/opnfv-apex/. These files have comments to help you customize them. - -1. deploy_settings.yaml - This file includes basic configuration options deployment. - -2. network_settings.yaml - This file provides Apex with the networking information that satisfies the - prerequisite `Network Requirements`_. These are specific to your environment. - -Running ``opnfv-deploy`` ------------------------- - -You are now ready to deploy OPNFV using Apex! -``opnfv-deploy`` will use the inventory and settings files to deploy OPNFV. - -Follow the steps below to execute: - -1. Execute opnfv-deploy - ``sudo opnfv-deploy [ --flat | -n network_setttings.yaml ] -i instackenv.json -d deploy_settings.yaml`` - If you need more information about the options that can be passed to opnfv-deploy use ``opnfv-deploy --help`` - --flat will collapse all networks onto a single nic, -n network_settings.yaml allows you to customize your - networking topology. - -2. Wait while deployment is executed. - If something goes wrong during this part of the process, - it is most likely a problem with the setup of your network or the information in your configuration files. - You will also notice different outputs in your shell. - -3. The message "Overcloud Deployed" will display when When the deployment is complete. Just above this message there - will be a URL that ends in port http://<host>:5000. This url is also the endpoint for the OPNFV Horizon Dashboard - if connected to on port 80. +.. include:: ../installation-instructions/baremetal.rst diff --git a/docs/configguide/introduction.rst b/docs/configguide/introduction.rst index af8e03b6..fba7922b 100644 --- a/docs/configguide/introduction.rst +++ b/docs/configguide/introduction.rst @@ -1,41 +1 @@ -Introduction -============ - -This document describes the steps to install an OPNFV Bramaputra reference -platform, as defined by the Genesis Project using the Apex installer. - -The audience is assumed to have a good background in networking -and Linux administration. - -Preface -======= - -Apex uses the RDO Manager Open Source project as a server provisioning tool. -RDO Manager is the RDO Project implimentation of OpenStack's Triple-O project. -The Triple-O image based life cycle installation tool provisions an OPNFV -Target System (3 controllers, n number of compute nodes) with OPNFV specific -configuration provided by the Apex deployment tool chain. - -The Apex deployment artifacts contain the necessary tools to deploy and -configure an OPNFV target system using the Apex deployment toolchain. -These artifacts offer the choice of using the Apex bootable ISO -(``opnfv-apex-bramaputra.iso``) to both install CentOS 7 and the -nessesary materials to deploy or the Apex RPM (``opnfv-apex.rpm``) -which expects installation to a CentOS 7 libvirt enabled host.
