This guide instructs how to build and install an Akraino Edge Stack (AES) Regional Controller node.

Contents

Table of Contents
excludeContents


Overview

The Regional Controller Node installation includes the following components:

Operating System

  • Redfish Integrated Dell Remote Access Controller (iDRAC) bootstrapping and hardware configuration
  • Linux OS (Ubuntu)

Regional Controller

'Build Server' remotely installs the OS and SW packages on a 'Bare Metal' server to create the 'Regional Controller' (i.e. the Bare Metal servers becomes the Regional Controller'). Once the RC is build it is used to subsequently deploy either Rover or Unicycle pods. After the Build Server has completed the creation of the Regional Controller node, the Build Server has no further role in any Network Cloud Rover and Unicycle Pod deployment. The Regional Controller Node installation includes the following components:

Operating System

  • Redfish Integrated Dell Remote Access Controller (iDRAC) bootstrapping and hardware configuration
  • Linux OS (Ubuntu)

Regional Controller

  • PostgreSQL DB
  • Camunda
  • PostgreSQL DB
  • Camunda Workflow and Decision Engine
  • Akraino Web Portal
  • LDAP configuration

Supplementary Components

Various supporting files are also installed on the Regional Controller, including:

  • OpenStack Tempest tests
  • YAML builds
  • ONAP scripts
  • Sample VNFs

 


NOTE:  The Regional Controller can be installed on an existing Ubuntu 16.04 server or virtual machine.  See the instructions below labeled:  Installation on an Existing Ubuntu Server or Virtual Machine

This installation guide refers to the following by way of example:

  • 192.168.2.43 (aknode43)Build Server (Linux Server with a Docker Containerinstalled)
  • 192.168.2.42 44 (aknode42aknode44)Bare Metal Server on which the Regional Controller will be installed
  • 192.168.41.4244Bare Metal Server iDRAC on which the Regional Controller will be installed

Steps herein presume the use of a root account. All steps are performed from the Build Server.

A clean, out-of-the-box Ubuntu environment is strongly recommended before proceeding.

Prerequisites

AES Regional Controller installation is orchestrated from a Build Server acting upon a Bare Metal Server.

Build Server

  • Any server or VM with Ubuntu Release 16.04
  • Packages: Latest versions of sshpass, xorriso, and python-requests
  • Docker 1.13.1 or later

Bare Metal Server

  • Dell PowerEdge R740 server with no installed OS
  • Two interfaces for primary network connectivity bonding
  • 802.1q VLAN tagging for primary network interfaces

System Check

Build Server 

Ensure Ubuntu Release 16.04 (specifically) and Docker 1.13.1 (or later) are installed: 

  • version of the following apt packages:
    • docker    (used to run dhcp and web containers)
    • python    (used for redfish api calls to bare metal server)
    • python-requests    (used for redfish api calls to bare metal server)
    • python-pip    (used to install hpe redfish tools)
    • sshpass    (used to copy keys to new server)
    • xorriso    (used to extract Ubuntu files to web server)
    • make    (used to build custom ipxe efi file used during bare metal server boot)
    • gcc    (used to build custom ipxe efi file used during bare metal server boot)

Bare Metal Server

  • Dell PowerEdge R740 Gen 14 server or HP DL380 Gen10 with no installed OS [ Additional types of hardware will be supported in the future release]
  • Two interfaces for primary network connectivity bonding
  • 802.1q VLAN tagging for primary network interfaces

System Check

Build Server 

Ensure Ubuntu Release 16.04 (specifically) and Docker version is 1.13.1 or newer:

Ensure the latest versions of Ensure required packages are installed including python, python-requests, python-pip, sshpassxorriso, and python-requests are , make, and gcc are installed.  Install any missing packages with apt-get install -y <package name>

Network Connectivity 

The Build Server must have connectivity to the Bare Metal Server iDRAC interface on ports 80 (http) and 443 (https).

  • The Bare Metal Server Server iDRAC/iLO interface and bonded production interfaces must be reachable from the Build Server.
  • The Build Server and Bare Metal Server primary networks must have one of the following characteristics:
    • The networks must be located on the same L2 network, or
    • DHCP requests must be forwarded from the Bare Metal Server primary network interface to the Build Server (e.g., via a DHCP relay/helper).

Specific steps to achieve this connectivity are beyond the scope of this guide. However, some verification can be performed. 

First, verify that at least ports 80 and 443 are open on the Bare Metal Server iDRAC interface: 

  • The switch configuration for the network bond of the Bare Metal Server primary interfaces must be set to bring up the bond on the first interface prior to lacp completing negotiation.
    • For Junos OS this option is typically called force-up and should be set on the first interface in the bond.
    • For Arista, this option is typically called lacp fallback.
    • Please refer to your network switch documentation to determine the correct configuration.

Here are logical views of two supported topologies as examples:

Specific steps to achieve this connectivity are beyond the scope of this guide. However, some verification can be performed. 

First, verify that at least port 443 is open on the Bare Metal Server iDRAC/iLO interface: 

Code Block
languagebash
# nmap -sS 192.168.41.44

Regional Controller

On the Build Server, update the Akraino run command (rc) file in /opt/akraino/region:

Code Block
languagebash
vim /opt/akraino/region/akrainorc

Set TARGET_SERVER_IP to the Bare Metal Server IP. This is the IP address of the Regional Controller. All other values may be left as-is.

Code Block
languagebash
export TARGET_SERVER_IP=192.168.2.44

Warning
titleIn Case of Errors

The Regional Controller installation is not idempotent at this time. If errors are encountered during this phase, it is recommended that the errors be triaged and resolved, followed by an Operating System re-installation. This will ensure a "clean slate" Bare Metal Server before trying again.
