Install the etcd-operator helm chart first. 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 0.8.3

Wait for etcd-operator 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


If you haven't done it yet, add the CORD repository to the list of your local repositories and update the repo index:

helm repo add cord
helm repo update

To install the VOLTHA helm chart:

helm install -n voltha cord/voltha --version=1.0.6 \
    --set etcd-cluster.clusterSize=3

Allow all etcd-cluster pods to start before using VOLTHA. If not all etcd-cluster pods are starting successfully, you may want to try --set etcd-cluster.clusterSize=1 above.


helm delete --purge 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@<node-ip> -p 30110

The default VOLTHA password is admin.

Building and using development images

In some cases you may want to build custom images to try out development code. In order to do that, from the CORD repository, do:

cd incubator/voltha
REPOSITORY=voltha/ TAG=dev VOLTHA_BUILD=docker make build
cd ~/cord/automation-tools/developer
bash -f dev -r

This set of commands builds the VOLTHA containers and pushes them to a local docker registry using a tag called dev.

Once the images are pushed to a docker registry on the POD, you can create a values file like the following one, to override the default chart values, so use your images:

# voltha-values.yaml
    repository: ''
    tag: 'dev'
    pullPolicy: 'Always'

    repository: ''
    tag: 'dev'
    pullPolicy: 'Always'

    repository: ''
    tag: 'dev'
    pullPolicy: 'Always'

    repository: ''
    tag: 'dev'
    pullPolicy: 'Always'

    repository: ''
    tag: 'dev'
    pullPolicy: 'Always'

Then, install VOLTHA using:

helm install -n voltha -f voltha-values.yaml cord/voltha --version=1.0.6
