Deploy Digital Channels

This topic is part of the manual Digital Channels Private Edition Guide for version Current of Digital Channels.


Learn how to deploy Digital Channels into a private edition environment.

Assumptions

  • The instructions on this page assume you are deploying the service in a service-specific namespace or OpenShift project, named in accordance with the requirements on Creating namespaces. If you are using a single namespace for all private edition services, replace the namespace element in the commands on this page with the name of your single namespace or project.
  • Similarly, the configuration and environment setup instructions assume you need to create namespace-specific (in other words, service-specific) secrets. If you are using a single namespace for all private edition services, you might not need to create separate secrets for each service, depending on your credentials management requirements. However, if you do create service-specific secrets in a single namespace, be sure to avoid naming conflicts.
Important
Make sure to review Before you begin for the full list of prerequisites required to deploy Digital Channels.

Prepare your environment

To prepare your environment for the deployment, complete the steps in this section for either OpenShift or Google Kubernetes Engine (GKE).

OpenShift

Log in to the OpenShift cluster from the host where you will run the deployment:
oc login --token <token> --server <url of api server>
First confirm the cluster is running:
oc get clusterversion
Create a new project for Digital Channels:
oc new-project nexus

GKE

Log in to the GKE cluster from the host where you will run the deployment:
gcloud container clusters get-credentials <cluster>
Create a JSON file called create-nexus-namespace.json with the following content:
{
  "apiVersion": "v1",
  "kind": "Namespace",
  "metadata": {
    "name": "nexus",
    "labels": {
      "name": "nexus"
    }
  }
}
Use the JSON file to create a new namespace for Digital Channels:
kubectl apply -f apply create-nexus-namespace.json
Now confirm the namespace was created:
kubectl describe namespace nexus

Configure a secret to access JFrog

If you haven't done so already, create a secret for accessing the JFrog registry:

kubectl create secret docker-registry <credential-name> --docker-server=<docker repo> --docker-username=<jfrog_username> --docker-password=<API_key_from_jfrog>

For OpenShift deployments, map the secret to the default service account (this is an optional step):

oc secrets link default <credential-name> --for=pull

Deploy

To deploy Digital Channels, you'll need the Helm package and override files you downloaded in a previous step. Copy values.yaml and the Helm package (nexus-<version>.tgz) to the installation location.

You must override the following key sections in values.yaml:

Here's an example of how your values.yaml file might look:
deploymentType: Deployment
replicaCount: 1
image:
  registry: pureengage-docker-staging.jfrog.io
  repository: nexus/nexus
  pullPolicy: IfNotPresent
imagePullSecrets: [ mycred ]
nameOverride: ""
fullnameOverride: ""
existingSecret:
existingConfig:
nexus:
  fqdn: "http://digital.<your-cluster>"
  redirectProtocol: "http://"
  redis:
    enabled: true
    nodes: "redis://<redis-url>:<redis-port>"
    useCluster: true
    enableTls: false
    password: $nexus_redis_password
  db:
    host: "<postgres-host>"
    port: <postgres-port>
    user: "<db-user>"
    password: nexus_db_password
    enableSsl: false
  social:
    apikey: ""
    retryTimeout: 10000
service:
  enabled: true
  type: ClusterIP
ingress:
  tls:
    - hosts:
      - digital.<your-cluster>
      secretName: letsencrypt 
  enabled: true
  hosts:
    - host: digital.<your-cluster>
      paths:
        - path: '/chat/v3/'
          port: http
        - path: '/nexus/v3/'
          port: http
        - path: '/ux/'
          port: http
        - path: '/admin/'
          port: http
        - path: '/auth/'
          port: http
monitoring:
  enabled: true
  alarms: true
Run the following command to install Digital Channels:
helm install nexus ./nexus-<version>.tgz --set version=<version> -f values.yaml

Validate the deployment

To validate the deployment, send the following GET request:

$nexusURL/health/detail 

Where $nexusURL is the fully qualified domain name (FQDN) for Digital Channels.

The response should look like this:
{
	"buildInfo": {
		"@genesys/nexus-admin-ux": "^1.0.21",
		"@genesys/nexus-ux": "^2.2.46",
		"version": "9.0.001.01.95292",
		"changeset": "8c3a2b34888d41b318d949a4bda2903368cf3bda",
		"timestamp": "Thu Oct 21 13:55:13 UTC 2021"
	},
	"startTime": "2021-10-22T10:40:27.456Z",
	"os": {
		"upTime": 1142897,
		"freemem": 105664512,
		"loadavg": [1.32, 0.68, 0.43],
		"totalmem": 2052542464
	},
	"upTime": 279363374,
	"memoryUsage": {
		"rss": 306659328,
		"heapTotal": 196685824,
		"heapUsed": 162114568,
		"external": 2490373,
		"arrayBuffers": 818214
	},
	"cache": {
		"ready": true,
		"state": "READY"
	},
	"db": {
		"ready": true
	},
	"state": "green"
}
The deployment was successful if state="green". You can also confirm that db.ready=true and cache.ready=true.
