This section provides instructions to quickly bring up SEBA.

Contents


Note: This Installation Guide assumes that prerequisite hardware is met and software (Akraino Stack with CORD Platform) have already been installed.

Specifically, wait for the three EtcdCluster CustomResourceDefinitions to appear in Kubernetes:

kubectl get crd | grep etcd | wc -l

Once the CRDs are present, proceed with the seba chart installation.

Overview

This page walks through the sequence of Helm operations needed to bring up the SEBA profile.

Prerequisites

It assumes the Akraino Stack with CORD Platform has already been installed.

Installation

Install components as a whole

Add the CORD repository and update indexes

$ helm repo add cord https://charts.opencord.org
$ helm repo update

Install the CORD platform
$ helm install -n cord-platform --version 6.1.0 cord/cord-platform

Wait until 3 etcd CRDs are present in Kubernetes
$ kubectl get crd | grep -i etcd | wc -l

Install the SEBA profile
$ helm install -n seba --version 1.0.0 cord/seba


Install the AT&T workflow
$ helm install -n att-workflow --version 1.0.2 cord/att-workflow

Alternatively, install as separate components

Add the official Kubernetes incubator repository (for Kafka) and update the indexes
$ helm repo add incubator http://storage.googleapis.com/kubernetes-charts-incubator
$ helm repo update

Add the CORD repository and update the indexes
$ helm repo add cord https://charts.opencord.org
$ helm repo update

Install the CORD platform components
$ helm install -n onos cord/onos
$ helm install -n xos-core cord/xos-core
$ helm install --version 0.13.3 \
             --set configurationOverrides."offsets.topic.replication.factor"=1 \
             --set configurationOverrides."log.retention.hours"=4 \
             --set configurationOverrides."log.message.timestamp.type"="LogAppendTime" \
             --set replicas=1 \
             --set persistence.enabled=false \
             --set zookeeper.replicaCount=1 \
             --set zookeeper.persistence.enabled=false \
             -n cord-kafka incubator/kafka

Optionally, install the logging and monitoring infrastructure components
$ helm install -n nem-monitoring cord/nem-monitoring
$ helm install --set elasticsearch.cluster.env.MINIMUM_MASTER_NODES="1" \
             --set elasticsearch.client.replicas=1 \
             --set elasticsearch.master.replicas=2 \
             --set elasticsearch.master.persistence.enabled=false \
             --set elasticsearch.data.replicas=1 \
             --set elasticsearch.data.persistence.enabled=false \
             -n logging cord/logging

Install etcd-operator and wait until 3 etcd CRDs are present in Kubernetes
$ helm install -n etcd-operator stable/etcd-operator --version 0.8.3
$ kubectl get crd | grep -i etcd | wc -l

Install the rest of the SEBA profile components
$ helm install -n voltha cord/voltha
$ helm install -n seba-service cord/seba-services
$ helm install -n base-kubernetes cord/base-kubernetes

Install the AT&T workflow
$ helm install -n att-workflow --version 1.0.2 cord/att-workflow

Verify your installation and next steps

Once the installation completes, monitor your setup using kubectl get pods. Wait until all pods are in Running state and “tosca-loader” pods are in Completed state.

Note: The tosca-loader pods may periodically transition into error state. This is expected. They will retry and eventually get to the desired state. Note: Depending on the profile you're installing, you may need to check also different namespaces (for example, check the voltha namespace if you're installing SEBA with kubectl get pods -n voltha)

Your POD is now installed and ready for use. To learn how to operate your POD continue to the SEBA configuration section.
