Setup in Google GCP (GKE Creation)

The following steps can be followed to install the LumenVox software within Google’s Kubernetes platform.

Create Kubernetes Cluster

Note: DNS associated with cluster can be noted for API calls into the LumenVox software

Set up cluster basics

Provide a cluster name and networking information (e.g. publicly available) to be set up
Version 1.27.6 is currently recommended – see latest minimum requirements in GitHub - lumenvox/helm-charts: LumenVox Kubernetes Helm Charts

Set up Node pool details

This will host your various pods
Numbers to be created will depend on call volumes and products used

The following default values are recommended but should be changed as per the client’s individual requirements:

Set up node configurations

The following default values are recommended however the client should select the operating system that best suits their needs. LumenVox recommend 8 vCPUs, 32GB memory per node.

Set up node security

The following default values are recommended but should be changed as per the client’s individual requirements:

Set up node networking

The following default values are recommended but should be changed as per the client’s individual requirement. LumenVox recommends using a public cluster network access.

Create VPC Firewall Rule for Rabbit MQ

Google doesn’t add automatically add this

Add persistent storage

The following default values are recommended but should be changed as per the client’s individual requirements:

Install GCloud CLI

This will include the required KubeCTL

Download from: https://cloud.google.com/sdk/docs/install

Connect to Cluster (configuring KUBECTL to talk to new cluster) ---this is on the user machine – e.g. remote connection tool.

1. gcloud container clusters get-credentials aether-test-cluster-1 --zone us-central1-c --project aether-gcp-

Install Linkerd CLI

This is run on KubeCTL and will install to local machine. We only support up to Linkerd edge-24.5.5.

1. curl --proto '=https' --tlsv1.2 -sSfL https://run.linkerd.io/install | sh

Add the Linkerd CLI to your path

1. export PATH=$PATH:$HOME/.linkerd2/bin

Install Linkerd

1. linkerd check --pre

2. linkerd install --crds | kubectl apply -f -

3. linkerd install | kubectl apply -f -

4. linkerd check

Install Jaeger

1. linkerd jaeger install | kubectl apply -f -

Install Linkerd Dashboard

1. linkerd viz install | kubectl apply -f

Should be ever need to uninstall Linkerd for troubleshooting purposes (e.g. deleting a cluster or you have issues with the Linkerd side cars you can use the following commands:

Uninstall Linkerd

1. linkerd viz uninstall | kubectl delete -f -

2. linkerd jaeger uninstall | kubectl delete -f -

3. linkerd uninstall | kubectl delete -f -

Install Helm

1. curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3

2. chmod 700 get_helm.sh

3. ./get_helm.sh4.

Install nginx Ingress

1. helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx

2. helm repo update

3. kubectl create ns ingress-nginx

4. helm upgrade --install ingress-nginx ingress-nginx --repo https://kubernetes.github.io/ingress-nginx -n ingress-nginx --create-namespace --set controller.hostNetwork=true --set controller.allowSnippetAnnotations=true

Create LumenVox Namespace

1. kubectl create namespace lumenvox

Change NameSpace

1. kubectl config set-context --current --namespace=lumenvox

Setup TLS for Ingress

The example below shows guideline values, clients can amend as needed e.g. certificate validity period and subject alternative name.

1. openssl genrsa -out server.key 2048

2. openssl req -new -x509 -sha256 -key server.key -out server.crt -days 3650 -addext "subjectAltName = DNS:lumenvox-api.testmachine.com, DNS:biometric-api.testmachine.com, DNS:management-api.testmachine.com, DNS:reporting-api.testmachine.com, DNS:admin-portal.testmachine.com, DNS:deployment-portal.testmachine.com"

3. kubectl create secret tls speech-tls-secret --key server.key --cert server.crt

Apply Secrets File

1. kubectl apply -f lumenvox-secrets.yaml

Installation of Helm Charts

Deploy Public Chart

1. helm install lumenvox lumenvox/lumenvox -f speech-values.yaml -n lumenvox
