This topic is part of the manual Genesys Authentication Private Edition Guide for version Current of Genesys Authentication.

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 Genesys Authentication:

Important

For OpenShift, you must deploy Genesys Authentication in the gws namespace if you are using the OpenShift Ingress Controller.

oc new-project gauth

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-gauth-namespace.json with the following content:

{
  "apiVersion": "v1",
  "kind": "Namespace",
  "metadata": {
    "name": "gauth",
    "labels": {
      "name": "gauth"
    }
  }
}

Use the JSON file to create a new namespace for Genesys Authentication:

kubectl apply -f apply create-gauth-namespace.json

Now confirm the namespace was created:

kubectl describe namespace gauth

Deploy

To deploy Genesys Authentication, you'll need the Helm package and your overrides file. Copy values.yaml and the Helm package (gauth-<version>.tgz) to the installation location.

For OpenShift, select the gauth project (or gws if you are using the OpenShift Ingress Controller) you created in Prepare your environment:

oc project gauth

For debugging purposes, use the following command to render templates without installing so you can check that resources are created properly:

helm template --debug /gauth-<version>.tgz -f values.yaml

The result shows Kubernetes descriptors. The values you see are generated from Helm templates, and based on settings from values.yaml. Ensure that no errors are displayed; you will later apply this configuration to your Kubernetes cluster.

Now you're ready to deploy Genesys Authentication:

helm install gauth ./gauth-<version>.tgz -f values.yaml -n gauth

Configure external access

Follow the instructions for either OpenShift or GKE to make the Genesys Authentication services accessible from outside the cluster.

Create routes in OpenShift

After deploying, make the Genesys Authentication services accessible from outside the OpenShift cluster using the standard HTTP port. Make sure to use the same hostname for all three routes. Genesys recommends using the following hostname format: gauth.<cluster-subdomain>. For example, the VCE cluster (https://console-openshift-console.apps.<yourclusterdomain>.com/) should have the hostname gauth.apps.<yourclusterdomain>.com

oc create route edge --service=<env-service> --hostname=<hostname> --path /environment
oc create route edge --service=<gauth-service> --hostname=<hostname> --path /auth
oc create route edge --service=<gauth-auth-ui-service> --hostname=<hostname> --path /ui/auth

Verify the new route is created in the gauth namespace (or gws if you are using the OpenShift Ingress Controller):

oc get route -n gauth

The result includes the following information about the services:

NAME            HOST/PORT                                          PATH                SERVICES              PORT   TERMINATION   WILDCARD
env             gauth.apps.<yourclusterdomain>.com                 /environment        gauth-environment     https                 None
gauth           gauth.apps.<yourclusterdomain>.com                 /auth               gauth-auth            https                 None
gauth-auth-ui   gauth.apps.<yourclusterdomain>.com                 /ui/auth            gauth-auth-ui         https                 None

Note: HOST is the host name generated by OpenShift.

Provision ingresses for GKE

After deploying, make Genesys Authentication services accessible from outside the GKE cluster using the NGINX Ingress Controller.

Create a YAML file called gauth-ingress.yaml with the content below. Note: Replace gws.<domain> and gauth.<domain> with your GWS and Genesys Authentication domains, such as gws.test.dev.

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: gauth-gws-ingress
  namespace: gauth
  annotations:
    # add an annotation indicating the issuer to use.
    cert-manager.io/cluster-issuer: "selfsigned-cluster-issuer"
    # Custom annotations for NGINX Ingress Controller
    kubernetes.io/ingress.class: "nginx"
    nginx.ingress.kubernetes.io/ssl-redirect: "false"
    nginx.ingress.kubernetes.io/use-regex: "true"
spec:
  rules:
  - host: gws.<domain> - e.g. gws.test.dev
    http:
      paths:
        - path: /ui/auth/.*
          backend:
            serviceName:  gauth-auth-ui
            servicePort: 80
        - path: /auth/.*
          backend:
            serviceName:  gauth-auth
            servicePort: 80
        - path: /environment/.*
          backend:
            serviceName:  gauth-environment
            servicePort: 80
  tls:
  - hosts:
    - gws.<domain> - e.g. gws.test.dev
    secretName: gauth-gws-ingress-cert

apiVersion: extensions/v1beta1
kind: Ingress

  namespace: gauth

    # add an annotation indicating the issuer to use.
    cert-manager.io/cluster-issuer: "selfsigned-cluster-issuer"
    # Custom annotations for NGINX Ingress Controller
    kubernetes.io/ingress.class: "nginx"
    nginx.ingress.kubernetes.io/ssl-redirect: "false"
    nginx.ingress.kubernetes.io/use-regex: "true"
spec:
  rules:
  - host: gauth.<domain> - e.g. gauth.test.dev
    http:
      paths:
        - path: /ui/auth/.*
          backend:
            serviceName:  gauth-auth-ui
            servicePort: 80
        - path: /auth/.*
          backend:
            serviceName:  gauth-auth
            servicePort: 80
 
        - path: /environment/.*
          backend:
            serviceName:  gauth-environment
            servicePort: 80
  tls:
  - hosts:
    - gauth.<domain> - e.g. gauth.test.dev
    secretName: gauth-gauth-ingress-cert

Create ingresses with the following command:

kubectl apply -f gauth-ingress.yaml -n gws

Validate the deployment

Check the installed Helm release:

helm list

The results should show the Genesys Authentication deployment details. For example:

NAME    NAMESPACE       REVISION        UPDATED                                 STATUS          CHART           APP VERSION
gauth   gauth           1               2021-05-20 11:56:32.5531685 +0530 +0530 deployed        gauth-0.1.77    0.1

Check the gauth namespace (or gws if you are using the OpenShift Ingress Controller) status:

helm status gauth

The result should show the namespace details with a status of deployed:

NAME: gauth
LAST DEPLOYED: Thu May 20 11:56:32 2021
NAMESPACE: gauth
STATUS: deployed
REVISION: 1
TEST SUITE: None

Check the Genesys Authentication Kubernetes objects created by Helm:

kubectl get all -n gauth

The result should show all the created pods, service ConfigMaps, and so on.

Finally, verify that you can now access Genesys Authentication at the following URL: https://<hostname>/ui/auth/sign-in.html
