From 3b86e1b9fafeab1261b1caae3b2d08ad410822b7 Mon Sep 17 00:00:00 2001 From: ChristopherPrice Date: Sun, 31 Jan 2016 19:19:36 +0100 Subject: Updating directory structure to add files to the central docs. Moved the introduction and baremetal installation instructions to /configguide. The files baremetal and introduction will be pulled into the central config guide document for release. (A little local file name juggling was required to accommodate the toolchain.) Once merged this should be pulled into the configguide. Will work on a patch for that now.

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 . + +1b. If your Jump host already has CentOS 7 with libvirt running on it then install the + opnfv-apex RPM from OPNFV artifacts . + +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://:5000. This url is also the endpoint for the OPNFV Horizon Dashboard + if connected to on port 80. diff --git a/docs/configguide/introduction.rst b/docs/configguide/introduction.rst new file mode 100644 index 00000000..af8e03b6 --- /dev/null +++ b/docs/configguide/introduction.rst @@ -0,0 +1,41 @@ +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. -- cgit 1.2.3-korg
