Radio Edge Cloud is Apache 2.0 licensed. The goal of the project is the packaging and installation of upstream Open Source projects. Each of those upstream projects is separately licensed. For a full list of packages included in REC you can refer to (the 313 in this URL is the Akraino REC/TA build number, see for the latest build.) All of the upstream projects that are packaged into the REC/TA build image are Open Source.


This document outlines the steps to deploy Radio Edge Cloud (REC) cluster. It has a minimum of three controller nodes. Optionally it may include worker nodes if desired. REC was designed from the ground up to be a highly available, flexible, and cost-efficient system for the use and support of Cloud RAN and 5G networks. The production deployment of Radio Edge Cloud is intended to be done using the Akraino Regional Controller which has been significantly enhanced during the Akraino Release 1 timeframe, but for evaluation purposes, it is possible to deploy REC without the Regional Controller. Regardless of whether the Regional Controller is used, the installation process is cluster oriented. The Regional Controller or a human being initiates the process on the first controller in the cluster, then that controller automatically installs an image onto every other server in the cluster using IPMI and Ironic (from OpenStack) to perform a zero touch install.

In a Regional Controller based deployment, the Regional Controller API will be used to upload the REC Blueprint YAML (available from the REC repository) which informs the Regional Controller of where to obtain the REC ISO images, the REC workflows (executable code for creating, modifying and deleting REC sites) and the REC remote installer component (a container image which will be instantiated by the create workflow and which will then invoke the REC Deployer (which is located in the ISO DVD disc image file) which conducts the rest of the installation.

The instructions below skip most of this and directly invoke the REC Deployer from the Baseboard Management Controller (BMC), integrated Lights Out (iLO) or integrated Dell Remote Access Controller (iDRAC) of a physical server. The basic workflow of the REC deployer is to copy a base image to the first controller in the cluster and then read the contents of a configuration file (typically called user_config.yaml) to deploy the base OS and all additional software to the rest of the nodes in the cluster.

Although the purpose of the Radio Edge Cloud is to run the RAN Intelligent Controller (RIC), the RIC software (which was written from scratch starting in the spring of 2019) is not quite stable enough yet to incorporate into the REC ISO image. The manual installation procedure described below does not result in the installation of the RIC. In the REC Continuous Deployment system, as of the Akraino Release 1 and 2 timeframe, a Jenkins job deploys a snapshot of the RIC and runs a small set of tests. These steps may be manually executed and this procedure is described in the last section of this WIKI document.  Fully automated installation of the RIC as part of the REC will not be complete until sometime in 2020. If you are interested in actually interfacing a REC appliance with eNodeB/gNode B and radio infrastructure you should really join the Radio Edge Cloud Project Meetings on a weekly basis and let the REC team know of your interest. We will be happy to coordinate with you and welcome any testing that you can do.

Pre-Installation Requirements for REC Cluster

Hardware Requirements:

REC is a fully integrated stack from the hardware up to and including the application, so for best results, it is necessary to use one of the tested hardware configurations. Although REC is intended to run on a variety of different hardware platforms, it includes a hardware detector component that customizes each installation based on the hardware present and will need (possibly minor) changes to run on additional hardware configurations. Preliminary support is present in Akraino Release 1 of REC for HP DL380 generation 9 and 10, Dell R740xd and Nokia Open Edge servers, but the primary focus of Release 1 testing is the Nokia Open Edge servers, so some issues may be encountered with other server types.

  • Minimum of 3 nodes
  • Total Physical Compute Cores:  60 (120 vCPUs)
  • Total Physical Compute Memory:  192GB minimum per node
  • Total SSD-based OS Storage:  2.8 TB (6 x 480GB SSDs)
  • Total Application-based Raw Storage:  5.7 TB (6 x 960GB SSD0
  • Networking Per Server:     Apps - 2 x 25GbE (per Server) and DCIM - 2 x 10GbE + 1 1Gbt (shared)                                        

The specific recommended configuration as of the Release 1 timeframe is the Open Edge configuration documented in the Radio Edge Cloud Validation Lab

BIOS Requirements:

  • BIOS set to Legacy (Not UEFI, although UEFI support is partially implemented and should be available in 2020)
  • CPU Configuration/Turbo Mode Disabled
  • Virtualization Enabled
  • IPMI Enabled
  • Boot Order set with Hard Disk listed as first in the list.

As of Release 1 and 2, Radio Edge Cloud does not yet include automatic configuration for a pre-boot environment. The following versions were manually loaded on the Open Edge servers in the Radio Edge Cloud Validation Lab using the incomplete but functional script available here. In the future, automatic configuration of the pre-boot environment is expected to be a function of the Regional Controller under the direction of the REC pod create workflow script.

  • BIOS1: 3B06
  • BMC1: 3.13.00
  • BMC2: 3.08.00
  • CPLD: 0x01

Network Requirements:

The REC cluster requires the following segmented  (VLAN), routed networks accessible by all nodes in the cluster:

  • External Operations, Administration and Management (OAM) Network
  • Out Of Band (OOB) (iLO/iDRAC) network(s)
  • Storage/Ceph network(s)
  • Internal network for Kubernetes connectivity
  • NTP and DNS accessibility

The REC installer will configure NTP and DNS using the parameters entered in the user_config.yaml. However, the network

must be configured for the REC cluster to be able to access the NTP and DNS servers prior to the install.

About user_config.yaml

The user_config.yaml file contains details for your REC cluster such as required network CIDRs, usernames, passwords,

DNS and NTP server ip addresses, etc.  The REC configuration is flexible, but there are dependencies: e.g., using DPDK

requires a networking profile with ovs-dpdk type, a performance profile with CPU pinning & hugepages and performance

profile links on the compute node(s).

The following link points to the latest user_config template with descriptions and examples for every available parameter:

user_config.yaml template

Note: the version number listed in the user_config.yaml needs to follow closely the version from the template. There is a strict version checking during deployment for the first two part of the version number. The following rules apply to the yaml's version parameter:

### Version numbering:
###    X.0.0
###        - Major structural changes compared to the previous version.
###        - Requires all users to update their user configuration to
###          the new template
###    a.X.0
###        - Significant changes in the template within current structure
###          (e.g. new mandatory attributes)
###        - Requires all users to update their user configuration according
###          to the new template (e.g. add new mandatory attributes)
###    a.b.X
###        - Minor changes in template (e.g. new optional attributes or
###          changes in possible values, value ranges or default values)
###        - Backwards compatible

YAML Requirements

  • The YAML files need to edited/created using Linux editors or in Windows Notepad++
  • YAML files do not support TABS.  You must space over to the location for the text.

Note:  You have a better chance at creating a working YAML by editing an existing file or using the template rather than starting from scratch.

Installing REC

Obtaining the ISO Image

Recent builds can be obtained from the Akraino Nexus server. Choose either "latest" or a specific build number from the old release images directory for builds prior to the AMD/ARM split or the AMD64 builds or the ARM64 builds and download the file install.iso.

Akraino ReleaseREC or TA ISO BuildBuild DateNotes


Build number 9 is known to NOT work on Dell servers or any of the ARM options listed below. If attempting to install on Dell servers, it is suggested to use builds from no earlier than June 10th


2019-11-18It is possible that there may still be some issues on Dell servers. Most testing has been done on Open Edge. Some builds between June 10th and November 18th have been successfully used on Dell servers, but because of a current lack of Remote Installer support for Dell (or indeed anything other than Open Edge), the manual testing is not as frequent as the automated testing of REC on Open Edge. If you are interested in testing or deploying on platforms other than Open Edge, please join the Radio Edge Cloud Project Meetings.
3 - AMD64

2020-05-29This is a minor update to Akraino Release 2 of AMD64 based Radio Edge Cloud
3 - ARM64

2020-04-13This is the first ARM based release of Radio Edge Cloud

Options for booting the ISO on your target hardware include NFS, HTTP, or USB memory stick. You must place the ISO in a suitable location (e.g., NFS server, HTTP(S) server or USB memory stick before starting the boot process. The file bootcd.iso, which is also in the same directory, is used only when deploying via the Akraino Regional Controller using the Telco Appliance Remote Installer. You can ignore bootcd.iso when following the manual procedure below.

Preparing for Boot from ISO Image

Nokia OpenEdge Servers

Using the BMC, configure a userid and password on each blade and ensure that the VMedia Access checkbox is checked.

The expected physical configuration as described in Radio Edge Cloud Validation Lab is that each server in the cluster has two SSD 480GB SATA 1dwpd M.2 2280 on a riser card inside the server and two SSD 960GB SATA 3dwpd 2.5 inch on the front panel. There is no RAID configuration used. The reference implementation in the Radio Edge Cloud Validation Lab uses one M.2 drive as the physical volume for LVM and both 2.5 inch SSDs as Ceph volumes.

HP Servers

Dell Servers

Provision the disk configuration of the server via iDRAC such that the desired disks will be visible to the OS in the desired order. The installation will use /dev/sda as the root disk and /dev/sdb and /dev/sdc as the Ceph volumes.

Uploading user_config.yaml

Go to your RC or jump server and scp (or sftp) your user_config.yaml to controller-1’s /etc/userconfig directory.

initial credentials: root/root.

scp user_config.yaml root@<controller-1 ip address>/etc/userconfig/

Select, 1 Start installation and OK.

After selecting Start Installation, the installation should start automatically, and the content of /srv/deployment/log/bootstrap.log should be displayed on the remote console.

Monitoring Deployment Progress/Status

You can monitor the REC deployment by checking the remote console screen or by tailing the logs on controller-1 node's /srv/deployment/log/ directory.

There are two log files:

bootstrap.log: deployment status log

cm.log: ansible execution log

tail -f /srv/deployment/log/cm.log

tail -f /srv/deployment/log/bootstrap.log

Note:  When the deployment to all the nodes has completed, “controller-1” will reboot automatically.

Special Attention Required on Dell

A Note on deploying on DELL severs:

Currently, a manual step is required when doing an installation on Dell servers.  After the networking has been set up and the deployment has started, the following message will be shown on the console screen on controller-2 and controller-3:

At this point, both controller-2 and controller-3 should be set to boot from virtual CD/DVD/ISO.

To do this:

  • Log on to the iDrac web interface
  • Select "Launch Virtual Console"
  • In the Virtual Console:
    • Select "Boot | Virtual CD/DVD/ISO" and confirm
    • Select "Power | Reset System (Warm Boot)" and confirm

Again, this needs to be done for both controller-2 and controller-3.  After this, the installation should continue normally.

As a reference, during this time, viewing the file /srv/deployment/log/cm.log on controller-1 will show the following:

   FAILED - RETRYING: Verify node provisioning state. Waiting for 60mins max. (278 retries left).

   FAILED - RETRYING: Verify node provisioning state. Waiting for 60mins max. (277 retries left).

   FAILED - RETRYING: Verify node provisioning state. Waiting for 60mins max. (276 retries left).

This will continue until the above manual step is completed or a timeout happens.  After the manual step, the following messages will appear:

   ok: [controller-2 -> localhost]

   ok: [controller-3 -> localhost]

Verifying Deployment

A post-installation verification is required to ensure that all nodes and services were properly deployed.

You need to establish an ssh connection to the controller’s VIP address and login with administrative rights.

tail /srv/deployment/log/bootstrap.log

You should see: Installation complete, Installation Succeeded.

Go to REC Test Document and follow the steps outlined there to ensure that all nodes and services were properly deployed.

Deployment Failures

Sometimes failures happen, usually due to misconfigurations or incorrect addresses entered.

To re-launch a failed deployment

There are two options for redeploying.  (Execute as root)

  1. /opt/cmframework/scripts/ /etc/userconfig/user_config.yaml --install &
  2. openvt -s -w /opt/start-menu/ &

Note:  In some cases modifications to the user_config.yaml may be necessary to resolve a failure. 

If re-deployment is not possible, then the deployment will need to be started from booting to the REC.iso,

RIC R0 Installation onto REC

REC Release R1 includes the ability to run the R0 version of the RIC.
This R0 is limited functionality of the RIC plaform, but demonstrates the basic RIC platform components of appmgr, rtmgmr, redis, e2term, etmgr.

Additionally it is possible to load robot test suites to verify functionality, but not all test cases will work in this version of RIC.
As more functionality becomes available, more test cases will work and more tests will be added.

Onboarding RIC R0 is a manual step at present, in future it will be included in the REC build process.
RIC R0 includes scripts to bring up the RIC onto a generic kubernetes platform.
To bring it up on the REC, follow the steps below.

Step 1:

Login to the controller 1 as cloudadmin and clone the scripts used to bring up the RIC on a REC cluster.

git clone

Step 2:

Copy the scripts to your home directory

cp rec/workflows/ rec/workflows/ rec/workflows/ ./

Step 3:

Run the script.


Once the script completes, verify the output below indicating successful deployment of the RIC helm charts.

+ helm install localric/ric --namespace ricplatform --name ric-full --set appmgr.appmgr.service.appmgr.extport=30099 --set e2mgr.e2mgr.service.http.extport=30199

Verify the RIC pods are all coming up and running.

kubectl get pods -n ricplatform

ric-full-dbaas-877f5788d-rpg87 1/1 Running 0 2m5s

ric-full-rtmgr-95f7cb5cc-bfhdx 1/1 Running 0 2m5s

Note:  It may take a little time so repeat the command at some intervals.  If they do not come up as Running, you should use standard kubernetes command such as kubectl describe, kubectl logs to troubleshoot and resolve the issue.

Now that you have running RIC R0, on the REC, you can install robot test scripts to do more verification of the RIC components. These at present only provide limited testing but more tests will be added later as more functionality is developed in later RIC releases.

  1. Hi Paul Carver,

           We want to port the REC into Aarch64 platform. Could you please give more detail information about install.iso so that we could install those software on Aarch64 platform step by step? And what is the base OS system? Thanks.

  2. Hi Paul Carver,

    We are building our cluster in our lab for REC. I need to understand why do we need 3 controllers in a 3 node cluster. I mean what is the purpose of 3 controllers ? And can we use these controllers  for hosting container loads like (RIC or Xapps)

    1. 3-controller nodes is the minimum number of Nodes required to provide a high-available infrastructure, which is basic requirement in TelCo. with a 3-controller setup the installation can seamlessly survive, and recover from the loss of a whole physical node

      but yes, containerized workloads can be instantiated on controller nodes too!

    2. Ankit Arora I agree with Levente Kálé 's reply and I would also add that for development purposes it would be nice to be able to deploy on a 3 VM cluster running on a single physical server, but we would never deploy that type of cluster in production. Since the priority for REC is to develop a blueprint for production deploy-able clusters we aren't focusing any effort on VMs. We focus on developing and testing for our target edge site hardware. However, we would welcome anyone who wants to help create a "devstack" for REC if doing so is helpful to them. But it can't be at the expense of the main goal of producing a production deploy-able system. So removing the quorum based cluster redundancy mechanisms isn't an acceptable change.
