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.

CONFIGURATION

PREREQUISITES

The voltha script uses several standard Linux tools to deploy VOLTHA including go, 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:

RESOURCEMINIMALFULL
K8s Control Plane Nodes11
K8s Workers23
EtcdOperator ComponentsOperator onlyOperator, Backup, Restore
EtcdCluster1 Member3 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

Demo @ Speed 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. 2.2, you could use the following command:

source releases/voltha-2.2 && voltha up

Please check the releases folder to see the available ones.

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

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.
