WebRTC Video Support in Customer widget via Secure link

https://expertflow-docs.atlassian.net/wiki/x/AYD3Dg

The WebRTC Video Call feature via secure link enhances the customer widget by allowing standalone video calls without relying on the chat features. This is facilitated through secure link and token authentication, ensuring privacy and security. The feature is activated based on a specific secure link and session code generated by the agent during an active chat with the customer on any chat channel, The Generated Link will be valid for the next 30 minutes allowing the customer to rejoin if mistaken disconnect any active video call session. Once the secure link expires, it will go through the Session Expired error on the screen.

Secure Link APIs Deployment:

Step 1: Clone the repository

CODE 
git clone -b main https://efcx:RecRpsuH34yqp56YRFUb@gitlab.expertflow.com/cti/securelinkgenreation_deployment.git
CODE 
cd securelinkgenreation_deployment

 

Step 2: Update configMap

FQDN and Widgetidentifier must be the same as the EFCX WebRTC widget.

  1. Open securelinkgenreation_deployment/ConfigMaps/ef-securelinkgeneration-configmap.yaml file and add the following parameters

    CODE 
       SPRING_DATASOURCE_URL : jdbc:postgresql://ef-postgresql.ef-external.svc.cluster.local:5432/securelinkgeneration_db
   SPRING_DATASOURCE_USERNAME : "sa"
   SPRING_DATASOURCE_PASSWORD : "Expertflow123"
   ENCRYPTION_KEY: "1234567890123456"
   webwidgetfqdn : https://cim.expertflow.com/customer-widget/#/widget
   source : "SLG"
   linktimeout : "30"
   widgetIdentifier : "webrtc-widget"



Step 3: Update FQDN

Expertflow CX should be accessible by a fully qualified domain name. Assign the FQDN that resolves to the control plane node or KubeVIP.

Replace <FQDN> with your FQDN for Expertflow CX and run this command.

CODE 
sed -i 's/devops[0-9]*.ef.com/<FQDN>/g' ConfigMaps/* Ingresses/nginx/* Ingresses/traefik/*

Step 4: Pull Image Mannualy

CODE 
CONTAINERD_ADDRESS=/run/k3s/containerd/containerd.sock /var/lib/rancher/rke2/bin/ctr  -n k8s.io i pull -u saifullah:saifullah96 gitimages.expertflow.com/cti/securelinkgeneration:1.6


Step 5: Update Deployment

CODE 
kubectl apply -f ConfigMaps/ef-securelinkgeneration-configmap.yaml
kubectl apply -f Services/ef-securelinkgeneration-service.yaml
kubectl apply -f Deployments/ef-securelinkgeneration-deployment.yaml
#Apply Ingresses 
#for RKE
kubectl apply -f Ingresses/nginx/ef-securelinkgeneration-ingress.yaml
#or 
#for Traefik
kubectl apply -f Ingresses/traefik/ef-securelinkgeneration-ingress.yaml
