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
- 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

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

Network Connectivity
The Build Server must have connectivity to the Bare Metal Server iDRAC interface on ports 80 (http) and 443 (https).
...
Verification of the Build Server and Bare Metal Server primary networks is beyond the scope of this guide.
Installation
Repository Cloning
Repositories are located under /opt/akraino:

Operating System
Begin the OS installation:
...
Note that any time estimates (e.g., "This step could take up to 15 minutes") and elapsed times are likely inaccurate. The total install time is longer, on the order of hours. Enjoy that beverage. 
Regional Controller
Update the Akraino run command (rc) file in /opt/akraino/region:
...
The Regional Controller Node installation is now complete.
Akraino Portal Operations
Login
Visit the portal URL http://REGIONAL_NODE_IP:8080/AECPortalMgmt/ where REGIONAL_NODE_IP is the Portal IP.
