Deploy VOLTHA

VOLTHA depends on having a kafka message bus deployed with a name of cord-kafka, so deploy that with helm before deploying the voltha chart.

First Time Installation

Download the helm charts incubator repository:

helm repo add incubator https://kubernetes-charts-incubator.storage.googleapis.com/

Install the etcd-operator helm chart. This chart provides a convenient way of creating and managing etcd clusters. When voltha installs it will attempt to use etcd-operator to create its etcd cluster. Once installed etcd-operator can be left running.

helm install -n etcd-operator stable/etcd-operator --version 0.8.0

Allow etcd-operator enough time to create the EtdCluster CustomResourceDefinitions. This should only be a couple of seconds after the etcd-operator pods are running. Check the CRD are ready by running the following:

kubectl get crd | grep etcd

Update dependencies within the voltha chart:

helm dep up voltha

Install the voltha helm chart. This will create the voltha pods and additionally create the etcd-cluster pods

helm install -n voltha voltha

Allow enough time for the 3 etcd-cluster pods to start before using the voltha pods.

Standard Uninstall

helm delete --purge voltha

Standard Install

helm install -n voltha voltha

Nodeports Exposed

  • Voltha CLI
    • Inner port: 5022
    • Nodeport: 30110
  • Voltha REST APIs
    • Inner port: 8882
    • Nodeport: 30125

Accessing the VOLTHA CLI

Assuming you have not changed the default ports in the chart, you can use this command to access the VOLTHA CLI:

ssh voltha@<pod-ip> -p 30110

The default VOLTHA password is admin.

Building and using development images

In some cases you want to build custom images to try out development code. The suggested way to do that is:

cd ~/cord/incubator/voltha
REPOSITORY=voltha/ TAG=dev VOLTHA_BUILD=docker make build
cd ~/cord/automation-tools/developer
bash tag_and_push.sh dev 192.168.99.100:30500

This set of commands will build the VOLTHA containers and push them to a local docker registry using a TAG called dev

NOTE: Read more about the tag_and_push script here

Once the images are pushed to a docker registry on the POD, you can use a values file like the following one:

# voltha-values.yaml
images:
  vcore:
    repository: '192.168.99.100:30500/voltha-voltha'
    tag: 'dev'
    pullPolicy: 'Always'

  vcli:
    repository: '192.168.99.100:30500/voltha-cli'
    tag: 'dev'
    pullPolicy: 'Always'

  ofagent:
    repository: '192.168.99.100:30500/voltha-ofagent'
    tag: 'dev'
    pullPolicy: 'Always'

  netconf:
    repository: '192.168.99.100:30500/voltha-netconf'
    tag: 'dev'
    pullPolicy: 'Always'

  envoy_for_etcd:
    repository: '192.168.99.100:30500/voltha-envoy'
    tag: 'dev'
    pullPolicy: 'Always'

and you can install VOLTHA using:

helm install -n voltha voltha -f voltha-values.yaml
