OPNFV Installation instruction for the template-os-nosdn-nofeature-ha scenario

1. Abstract

This document describes how to install the <template> scenario of the Colorado release of OPNFV.

The <template> scenario will use Fuel as a deployment tool, installing and deploying an OPNFV based OpenStack in high availability on a Pharos compliant infrastructure.

2. Introduction

This document provides guidelines on how to install and configure the <template> scenario of OPNFV including required software and hardware configurations.

Although the available installation options give a high degree of freedom in how the system is set-up, including architecture, services and features, etc., said permutations may not provide an OPNFV compliant reference architecture. This instruction provides a step-by-step guide that results in an OPNFV Compliant deployment.

The audience of this document is assumed to have good knowledge in networking and Unix/Linux administration.

3. Preparation

Before starting the installation of the <scenario> scenario some preparation must be done. You may choose to install the <scenario> scenario using an ISO image, or executing the installation from a prepared jumphost.

3.1. Preparing your jumphost to install by script

To deploy the <scenario> scenario from a script you will need to prepare the jumphost with a compatible operating system. Prepare your jumphost running CentOS 7 with libvirt running on it. You may then install the RDO Release 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.

3.2. Preparing your jumphost using an ISO image

An alternative to preparing your own jumphost id to use a <scenario> ISO image as a boot image. Download or build the ISO image according to the following instructions.

3.2.1. Retrieving the ISO image

If you choose to install the <scenario> scenario from an ISO image you must first retrieve the <template-containing>.iso image of the Colorado release. This can be found can be found at <hyperlink required>.

3.2.2. Building the ISO image

Alternatively, you may choose to build the Fuel .iso from source by cloning the opnfv/fuel git repository. To retrieve the repository for the Colorado release use the following command:

$ git clone https://gerrit.opnfv.org/gerrit/fuel

Check-out the Colorado release tag to set the HEAD to the baseline required to replicate the Colorado release:

$ git checkout colorado.1.0

Go to the fuel directory and build the .iso:

$ cd fuel/build; make all

For more information on how to build, please see Reference: 14

3.2.3. Booting from the ISO image

Mount the <scenario> ISO file/media as a boot device on the jump host server. If all your hardware preparation is complete at this time you should reboot the jumphost to establish the deployment server.

3.3. Additional preparations

Additionally, familiarize yourself with Fuel by reading the following documents:

  • Fuel planning guide, please see Reference: 8
  • Fuel user guide, please see Reference: 9
  • Fuel operations guide, please see Reference: 10
  • Fuel Plugin Developers Guide, please see Reference: 11

Prior to installation, a number of deployment specific parameters must be collected, those are:

  1. Provider sub-net and gateway information
  2. Provider VLAN information
  3. Provider DNS addresses
  4. Provider NTP addresses
  5. Network overlay you plan to deploy (VLAN, VXLAN, FLAT)
  6. How many nodes and what roles you want to deploy (Controllers, Storage, Computes)
  7. Monitoring options you want to deploy (Ceilometer, Syslog, etc.).
  8. Other options not covered in the document are available in the links above

This information will be needed for the configuration procedures provided in this document.

4. Hardware requirements

4.1. The Pharos Lab

Hardware requirements for OPNFV infrastuctures are specified by the Pharos project. The Pharos project provides an OPNFV hardware specification for configuring your hardware at: http://artifacts.opnfv.org/pharos/docs/pharos-spec.html .

4.2. Virtual deployment hardware requirements

To perform a virtual deployment of an OPNFV scenario establised different hardware requirements. The server requirements for this type of deployment are outlined in the <missing spec>.

5. <scenario> software installation and deployment

This section describes the installation of the OPNFV installation server (jumphost) as well as the deployment of the <scenario> OPNFV reference platform stack across a server cluster.

5.1. Install jumphost

If you have not already done so, prepare your jumphost according the instructions in _#ref_Preparation this can be done using an ISO image with the following commands

    • Replace the URI values for the “Name” values outlined below:
    • “ubuntu” URI=”deb http://<ip-of-fuel-server>:8080/mirrors/ubuntu/ trusty main”
    • “ubuntu-security” URI=”deb http://<ip-of-fuel-server>:8080/mirrors/ubuntu/ trusty-security main”
    • “ubuntu-updates” URI=”deb http://<ip-of-fuel-server>:8080/mirrors/ubuntu/ trusty-updates main”

    • Click <Save Settings> at the bottom to Save your changes

11. Target specific configuration

  1. Set up targets for provisioning with non-default “Offloading Modes”

    Some target nodes may require additional configuration after they are PXE booted (bootstrapped); the most frequent changes are in defaults for ethernet devices’ “Offloading Modes” settings (e.g. some targets’ ethernet drivers may strip VLAN traffic by default).

    If your target ethernet drivers have wrong “Offloading Modes” defaults, in “Configure interfaces” page (described above), expand affected interface’s “Offloading Modes” and [un]check the relevant settings:

  2. Set up targets for “Verify Networks” with non-default “Offloading Modes”

    NOTE: Check Reference 15 for an updated and comprehensive list of known issues and/or limitations, including “Offloading Modes” not being applied during “Verify Networks” step.

    Setting custom “Offloading Modes” in Fuel GUI will only apply those settings during provisioning and not during “Verify Networks”, so if your targets need this change, you have to apply “Offloading Modes” settings by hand to bootstrapped nodes.

    E.g.: Our driver has “rx-vlan-filter” default “on” (expected “off”) on the openstack interface(s) “eth1”, preventing VLAN traffic from passing during “Verify Networks”.

    • From Fuel master console identify target nodes admin IPs:

      $ fuel nodes

    • SSH into each of the target nodes and disable “rx-vlan-filter” on the affected physical interface(s) allocated for OpenStack traffic (eth1):

      $ ssh root@10.20.0.6 ethtool -K eth1 rx-vlan-filter off

    • Repeat the step above for all affected nodes/interfaces in the POD.

12. Verify Networks

It is important that the Verify Networks action is performed as it will verify that communicate works for the networks you have setup, as well as check that packages needed for a successful deployment can be fetched.

From the FUEL UI in your Environment, Select the Networks Tab and select “Connectivity check” on the left pane

  • Select <Verify Networks>
  • Continue to fix your topology (physical switch, etc) until the “Verification Succeeded” and “Your network is configured correctly” message is shown

13. Deploy Your Environment

Deploy the environment.

  • In the Fuel GUI, click on the “Dashboard” Tab.
  • Click on <Deploy Changes> in the “Ready to Deploy?” section
  • Examine any information notice that pops up and click <Deploy>

Wait for your deployment to complete, you can view the “Dashboard” Tab to see the progress and status of your deployment.

14. Installation health-check

  1. Perform system health-check (see figure below)

    • Click the “Health Check” tab inside your Environment in the FUEL Web UI
    • Check <Select All> and Click <Run Tests>
    • Allow tests to run and investigate results where appropriate
