VOLTHA DEPLOYMENT TOOL
Thie repository describes how to the the voltha script to install a VOLTHA deployment. voltha can be used to deploy an instance into an existing Kubernetes cluster (physical or virtual) or can be start up a local docker-in-docker KinD Kuberentes cluster in which to deploy VOLTHA.
When deploying VOLTHA there are several configuration options tha can be set as described in the CONFIGURATION section below. All configuration options are specified as envirment variables.
PREREQUISITES
The voltha script uses several standard Linux tools to deploy VOLTHA including curl, sed, and jq. This tools must be installed before using the script. The script checks for the presence of these tools before it deployes VOLTHA and will exit with an error if the tools are not present.
NOTE: If you are deploying a KinD Kubernetes cluster using the voltha script, you must also also have Docker installed
INSTALL TYPE
The voltha script can install two variations or types of a VOLTHA deployment: minimal or full. The difference is characterized in the following table:
| RESOURCE | MINIMAL | FULL |
|---|---|---|
| K8s Control Plane Nodes | 1 | 1 |
| K8s Workers | 2 | 3 |
| EtcdOperator Components | Operator only | Operator, Backup, Restore |
| EtcdCluster | 1 Member | 3 Members |
Throughout this README.md file deployment and configuration files are referenced in the form $TYPE-cluster.cfg and $TYPE-values.yaml. Depending on which type of deloyment you wish to install replace $TYPE with either minimal or full. If you set the environment variable TYPE to the desired deployment type, example below, then the commands can be executed via a simply copy and paste to your command line.
export TYPE=minimal
TL;DR
OK, if you really don't care how it starts and you just want it started. After cloning the repository and making sure you have the prerequisites installed, just execute
DEPLOY_K8S=y WITH_BBSIM=y WITH_RADIUS=y CONFIG_SADIS=y ./voltha up
and the minimal cluster should start.
To remove voltha use DEPLOY_K8S=y ./voltha down
RUN WITHOUT CLONING REPOSITORY
The voltha script can be run without cloning the complete repository. To do so, download the script and run it.
curl -sSL https://raw.githubusercontent.com/opencord/kind-voltha/master/voltha --output ./voltha chmod +x ./voltha DEPLOY_K8S=y WITH_BBSIM=y WITH_RADIUS=y CONFIG_SADIS=y ./voltha up
NOTE: Shown significantly sped up (20x), actual install was about 8 minutes.
CONFIGURATION
The option should be set using environment variables, thus to start VOLTHA with the BBSIM POD, RADIUS, and ONOS SADIS configured you could use the following command:
WITH_BBSIM=yes WITH_RADIUS=y CONFIG_SADIS=y voltha up
To start a specific version of VOLTHA, e.g. 2.3, you could use the following commands:
git checkout tags/3.0.3 -b 3.0.3 source releases/voltha-2.3 && voltha up
Please check the releases folder to see the available ones and pick the correct tag associatet do that release.

Custom Namespaces
Separate namespaces can be specified for various components
VOLTHA_NS(default:voltha) for cores, ofagent, Etcd (yes), Kafka (yes)ADAPTER_NS(default:voltha) for device adaptersINFRA_NS(default:default) for RADIUS, ONOS, Etcd (external), Kafka (external)BBSIM_NS(default:voltha) for BBSIM instances
As an example BBSIM_NS=devices deployes BBSim in the devices namespace.
External Kafka, Etcd and ONOS
WITH_ETCD, WITH_KAFKA and WITH_ONOS can have different values depending on the deployment needs:
| VALUE | DESCRIPTION |
|---|---|
yes or y | installs Etcd and Kafka in the voltha namespace |
external | installs Etcd and Kafka in the default namespace |
<endpoint> | connects the deployment to pre-deployed instance of the service |
When specifying the <endpoint> of the service the format for each of these is service-name[:port]. Port is optional and will default to the standard port for the given service. For example, WITH_KAFA=kafka.infra.svc.cluster.local
Specifying the endpoint enable to use ./voltha up incrementally, for example:
DEPLOY_K8S=n WITH_BBSIM=y WITH_RADIUS=no CONFIG_SADIS=no WITH_ONOS=onos-openflow.infra.svc.cluster.local WITH_ETCD=etcd-cluster-client.infra.svc.cluster.local WITH_KAFKA=kafka.infra.svc.cluster.local INFRA_NS=infra BBSIM_NS=devices ADAPTER_NS=adapters ./voltha up
starts VOLTHA with external ONOS,KAFKA,ETCD in the infra namespace.
CONFIG_SADIS Values
| VALUE | DESCRIPTION |
|---|---|
yes or file | use the contents of a file to configure SADIS in ONOS. The file used defaults toonos-files/onos-sadis-sample.json but can be specified via the SADIS_CFGenvironment variable |
no | do not configure ONOS for SADIS usage |
url | configure ONOS to use SADIS via a URL. The URL used for subscriber information is specified in the variable SADIS_SUBSCRIBERS and the URL used for bandwidthprofiles is specified in the variable SADIS_BANDWIDTH_PROFILES |
bbsim | configure ONOS use use the SADIS servers that are part of BBSIM |
external | an additional helm chart will be installed (bbsim-sadis-server) and ONOS will be configured to use that service for SADIS queries |
Controlling VOLTHA with an ONOS cluster
To provide HA, resilinecy and failover ONOS can be configured in cluster mode. A 3 node ONOS deployment for example can be achieved via the full configuration:
TYPE=full WITH_ONOS=classic NUM_OF_ONOS=3 NUM_OF_ATOMIX=3 ./voltha up
Please note the TYPE=full that deploys a 3 worker nodes for k8s and WITH_ONOS=classic that uses the cluster-enabled helm chart for ONOS (version 2.2). The NUM_OF_ONOS=3 NUM_OF_ATOMIX=3 flags set the number of Atomix nodes and ONOS nodes. As usual one can add as many other options, for example CONFIG_SADIS=y.
GENERATED CONFIGURATION
When the voltha script is run it generates a file that contains the configuration settings. This file will be named $TYPE-env.sh. The user can source this file to set the configuration as well as establish key environment variables in order to access VOLTHA, including:
| VARIABLE | DESCRIPTION |
|---|---|
| KUBECONFIG | Sets the configuration file for the Kubernetes control application kubectl |
| VOLTCONFIG | Sets the configuration file for the VOLTHA control application voltctl |
| PATH | Augments the PATH to include kubectl and voltctl |
After voltha up is run, it is useful to source this file.
QUICK CHECK
After source the $TYPE-env.sh file, you should be able to access VOLTHA via the control application voltctl. To validate this you can use the following command
voltctl version
and should see output similar to
Client: Version 1.0.14 Go version: go1.12.8 Vcs reference: 086629f0403fe67213fa0df5dc4d7b7ee317cbac Vcs dirty: false Built: 2020-03-03T13:48:00Z OS/Arch: linux/amd64 Cluster: Version 2.3.3-dev Go version: 1.13.8 Vcs feference: aa8bd4dcc3510caf2c5362106d9bff2852663d31 Vcs dirty: false Built: 2020-03-06T16:16:47Z OS/Arch: linux/amd64
If you've run the voltha script with WITH_BBSIM=y you can now create a BBSIM OLT with
voltctl device create -t openolt -H bbsim0.voltha.svc:50060
TROUBLESHOOTING
When VOLTHA is installed the install log is written to the file install-$TYPE.log. If the install appears stalled or is not completing consulting this file may indicate the reason.
Similarly, when VOLTHA is uninstalled down-$TYPE.log is written and should be consulted in the event of an error or unexpected result.
