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

...

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 Workflow and Decision Engine
• Akraino Web Portal
• LDAP configuration

...

• 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

...

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

  • 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)

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: 

# nmap -sS 192.168.41.44 
Starting Nmap 7.01 ( https://nmap.org ) at 2018-07-10 13:55 UTC Nmap scan report for 192.168.41.44 Host is up (0.00085s latency).
