There will be need of olt-service and XOS updates for SEBA 2.0 in order to work with voltha 2.x architecture.

New voltctl can be used from: https://github.com/opencord/voltctl or from https://github.com/ciena/voltctl

Building  https://github.com/opencord/voltctl:

1. Ensure go 1.13 or later is installed
2. make build, then make install

Building https://github.com/ciena/voltctl:

1. Get release source files into <go dir>/src/github.com/ciena/voltctl
2. make build, then make install

Fix patches attached: 0001-Voltha-2.x-bbsim-fix.patch 0001-Voltha-2.x-onos-fix.patch

ONOS 2.2.2 is used for voltha 2.3 and new ONOS applications. Source code and documentation: https://docs.voltha.org/2.3.0/release_notes/voltha_2.3.html

There is no onos 2.2.2 chart in opencord for the moment but https://charts.opencord.org/onos-3.0.1.tgz can be used to use the updates for deployment and log using new karaf version 4.2.8

Patches attached for using non private kafka and etcd clusters so all pods can share it not just voltha pods: 

0001-voltha-2.x-public-kafka-and-etcd-clusters.patch

0001-voltha-2.x-public-kafka-and-etcd-clusters-automation.patch

The new voltha 2.x architecture is very different by the old 1.x voltha and requires several updates in seba that are current unavailable in opencord charts. One of the updates due architecture changes is that voltha APIs differs and are used over gRPC over http2 instead of restful APIs. Also ssh access seems unavailable even if it is documented (ssh pod and service is missing). Due voltha API limitation volt seba service will need updates and not only but seems to be unavailable in opencord at this time. Regarding ssh missing, it seems voltctl tool is available and shall be enough to debug the devices and some limited configuration. 

Patches for helm-charts and automation tools attached: 0001-Voltha-2.x-helm-charts-updates.patch respective 0001-Voltha-2.x-automation-tools-example.patch and includes:

1. charts updates
2. New voltha230 and related components like adapters and simulator charts added
3. bbsim added
4. Installing voltha after onos according opencord recommendation due some potential errors in onos

Voltha is installed from opencord for testing using the following commands (voltha 2.3 example):

git clone https://gerrit.opencord.org/voltha-test-manifest.git -b voltha-2.3
sudo apt-get install repo
git clone https://gerrit.googlesource.com/git-repo
repo init -u https://gerrit.opencord.org/voltha-test-manifest.git -b voltha-2.3 --current-branch
repo forall -c "git reset --hard"
repo sync -d -c -q --force-sync --jobs=4
repo manifest -o - -r
git rev-parse HEAD
sudo snap install yq
./kind-voltha/voltha

./kind-voltha/voltha is the script from where can be seen how helm is used to install voltha components, onos, kafka, etcd and other commands like port forwarding.

Voltha robot tests can be run from voltha-system-tests as follows:

1. make vst_venv

2. source ./vst_venv/bin/activate ; set -u ;

3. cd tests/functional

4. VOLTCONFIG=_{/.volt/config KUBECONFIG=}/.kube/config robot -V <full path here>/voltha-system-tests/tests/data/bbsim-kind.yaml Voltha_PODTests.robot

Remains to investigate other SEBA components dependent of voltha 2.3.
