All the networks involved in the OPNFV infrastructure as well as the provider +networks and the private tenant VLANs needs to be manually configured. + +The Jumphost can be installed using the bootable ISO or by other means including the +(``opnfv-apex``) RPM and virtualization capabilities. The Jumphost should then be +configured with an IP gateway on its admin or public interface and configured with a +working DNS server. The Jumphost should also have routable access to the lights out network. + +``opnfv-deploy`` is then executed in order to deploy the Instack VM. ``opnfv-deploy`` uses +three configuration files in order to know how to install and provision the OPNFV target system. +The information gathered under section `Execution Requirements (Bare Metal Only)`_ is put +into the YAML file (``/etc/opnfv-apex/inventory.yaml``) configuration file. 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. This includes +MAC address, IPMI, Networking Environment and OPNFV deployment options. + +Once configuration is loaded and Instack is configured it will then reboot the nodes via IPMI. +The nodes should already be set to PXE boot first off the admin interface. The nodes will +first PXE off of the Instack PXE server and go through a discovery/introspection process. + +Introspection boots off of custom introspection PXE images. These images are designed to look +at the properties of the hardware that is booting off of them and report the properties of +it back to the Instack node. + +After introspection Instack will execute a Heat Stack Deployment to being node provisioning +and configuration. 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. + +.. _`Execution Requirements (Bare Metal Only)`: requirements.html#execution-requirements-bare-metal-only +.. _`Network Requirements`: requirements.html#network-requirements diff --git a/docs/installation-instructions/introduction.rst b/docs/installation-instructions/introduction.rst index 883c148a..af8e03b6 100644 --- a/docs/installation-instructions/introduction.rst +++ b/docs/installation-instructions/introduction.rst @@ -1,2 +1,41 @@ -.. include:: ../configguide/introduction.rst +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. The RPM +contains a collection of configuration file, prebuilt disk images, +and the automatic deployment script (``opnfv-deploy``). + +An OPNFV install requires a "Jumphost" in order to operate. The bootable +ISO will allow you to install a customized CentOS 7 release to the Jumphost, +which includes the required packages needed to run ``opnfv-deploy``. +If you already have a Jumphost with CentOS 7 installed, you may choose to +skip the ISO step and simply install the (``opnfv-apex.rpm``) RPM. The RPM +is the same RPM included in the ISO and includes all the necessary disk +images and configuration files to execute an OPNFV deployment. Either method +will prepare a host to the same ready state for OPNFV deployment. + +``opnfv-deploy`` instantiates an RDO Manager Instack VM server using libvirt +as its provider. This VM is then configured and used to provision the +OPNFV target deployment (3 controllers, n compute nodes). These nodes can +be either virtual or bare metal. This guide contains instructions for +installing either method. diff --git a/docs/installation-instructions/virtualinstall.rst b/docs/installation-instructions/virtualinstall.rst index 5ca20d4f..b31a6af0 100644 --- a/docs/installation-instructions/virtualinstall.rst +++ b/docs/installation-instructions/virtualinstall.rst @@ -81,3 +81,6 @@ and read to be SSHed to. | ``ping 192.168.37.1`` Now continue with the `Verifying the Setup`_ section. + +.. _`Install Bare Metal Jumphost`: baremetal.html +.. _`Verifying the Setup`: verification.html |
