Deploy Voice Microservices

From Genesys Documentation
Jump to: navigation, search
This topic is part of the manual Voice Microservices Private Edition Guide for version Current of Voice Microservices.

Learn how to deploy Voice Microservices 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 Voice Microservices.

To deploy the Tenant service, see the Tenant Service Private Edition Guide.

For information about deploying Voicemail Service, see Deploy Voicemail.

General deployment prerequisites

Before you deploy the Voice Services, you must deploy the infrastructure services. See Third-party prerequisites for the list of required infrastructure services.

In addition, see Consul requirements for Voice services and Redis requirements for Voice services for information about specific configuration that must be completed in Consul before you configure or deploy Voice Microservices.

To override values for both the infrastructure services and voice services, see Override Helm chart values.

Deployment order for Voice Microservices

Genesys recommends the following order of deployment for the Voice Microservices:

Create the Voice namespace

Before deploying Voice Services and their dependencies, create a namespace using the following command:

kubectl create ns voice

In all Voice Services and the configuration files of their dependencies, the namespace is voice. If you want a specific, custom namespace, create the namespace (using the preceding command) and remember to change the namespace in files, as required.

Deploy Voice services

Voice Services require a Persistent Volume Claim (PVC); the Voice SIP Cluster Service uses a persistent volume to store traditional SIP Server logs. Before deploying Voice Services, create the PVC.

Storage class and Claim name

The created persistent volume must be configured in the sip_node_override_values.yaml file as shown below:

# pvc will be created for logs
volumes:
  pvcLog:
    create: true
    claim: sip-log-pvc
    storageClass: voice
    volumeName: <pv name> (ex sip-log-pv)
   
  pvcJsonLog:
    create: true
    claim: sip-json-log-pvc
    storageClass: voice
    volumeName: <pv name> (ex sip-log-pv)

Configure the DNS Server for voice-sip

The Voice SIP Cluster Service requires the DNS server to be configured in its sip_node_override_values.yaml file. Follow the steps in the Kubernetes documentation to install a dnsutils pod. Using the dnsutils pod, get the dnsserver that's used in the environment.

The default value in the SIP Helm chart is 10.0.0.10. If the dnsserver address is different, update it in the sip_node_override_values.yaml file as shown below:

# update dns server ipaddress
  context:
    envs:
      dnsServer: "10.202.0.10"

Voice Service Helm chart deployment

Deploy the Voice Services using the provided Helm charts.

Deploy in OpenShift

Add a rule for Consul DNS forwarding

In the OpenShift Container Platform (OCP), as part of the general deployment prerequisites, you must add a rule for Consul DNS forwarding. OpenShift sends DNS requests to the DNS server in the openshift-dns namespace. To forward Consul FQDN resolution to a Consul DNS server, add the forwarding rule to the configmap of the default DNS operator. Save the Consul DNS IP address using the following command:

kubectl get svc consul-dns -n <consul namespace> -o jsonpath={.spec.clusterIP} (Internal IP of consul-dns service)
> oc edit dns.operator/default
Add the below specs:
spec:
servers:
- name: consul-dns
zones:
- consul
forwardPlugin:
upstreams:
- <Internal IP of consul-dns service>

Persistent volumes

The general Voice Services deployment is described in Deploy Voice Services. There are some differences when creating PVCs in the OpenShift Container Platform (OCP). This section describes the configuration for OCP.

Persistent Volume in OCS Storage Type

A Storage Class might have been created already in the OCP. This Storage Class is used for creating PVCs and must be set in the override values of the sip_node_override_values.yaml file.

For an OpenShift cluster with OpenShift Container Storage (OCS), configure the Storage Class to be used for creating the persistent volume. In the case of OCS, the PV is created automatically when the PVC is claimed. For such clusters, the volumeName parameter in the sip_node_override_values.yaml file must be empty.

#  PVC's section
## This section defines about creating PVCs
volumes:
  pvcLog:
    create: true                                    # create defines whether a PVC needs to be created with the chart.
    claim: sip-log-pvc                              # Name of PVC
    volumeName:                                     # To bind this PVC to specified Persistent Volume.In case of Openshift, this is required only for NFS mounting and not needed for OCS.
    claimSize: 10Gi                                 # This field sets the storage size requested by PVC
    storageClass: voice                             # This field sets the storage class requested by PVC
    mountPath: /opt/genesys/logs/volume             # Volume mount path for PV
	       
  pvcJsonLog:
    create: true                                    # create defines whether a PVC needs to be created with the chart.
    claim: sip-json-log-pvc                         # Name of PVC
    volumeName:                                     # To bind this PVC to specified Persistent Volume.In case of Openshift, this is required only for NFS mounting and not needed for OCS.
    claimSize: 10Gi                                 # This field sets the storage size requested by PVC
    storageClass: voice                             # This field sets the storage class requested by PVC
    mountPath: /opt/genesys/logs/sip_node/JSON      # Volume mount path for PV

Configure the DNS Server for voice-sip

The Voice SIP Cluster Service requires the DNS server to be configured in its sip_node_override_values.yaml file.

In the OCP environment, you can find the Kubernetes DNS server name using the following command:

oc get dns.operator/default -o jsonpath={.status.clusterIP}

The default value in the SIP Helm chart is "10.0.0.10"; if the DNS server address is different, update it in the sip_node_override_values.yaml file as shown below:

# update dns server ipaddress
  context:
    envs:
      dnsServer: "10.202.0.10"

Deploy the Tenant service

The Tenant Service is included with the Voice Microservices, but has its own deployment procedure. To deploy the Tenant Service, see Deploy the Tenant Service.

Validate the deployment

Follow the steps below to validate the successful deployment of voice microservices.

  1. Verify the helm deployments using the following command.
    helm list -n voice

  4. Verify the health status of the pods in Consul dashboard.
    If the services are running and in Ready state, the health check will be marked as Green in Consul dashboard.
    Voicemcs deploy validate consul.png
  5. Check the versions of microservices in Grafana dashboard.
    Only if voice-dashboards are deployed in the voice namespace, you can perform this check in the dashboard.
    Voicemcs deploy validate grafana.png
  6. Check for any crash, KafkaJS or Redis connection errors in Prometheus, Grafana dashboards and/or logs of the respective microservices.

From a functional point of view, you can validate the voice microservices deployment by performing the following steps.

  1. Before you can validate the voice microservices, you must create few objects in the Tenant configdb to start the verification.
    1. Port forward the Tenant instance at 8888 port and access the tenant objects through Configuration Manager application.
      kubectl port forward t2100-0 8888:8888 -n voice
    2. Create a few Directory Numbers (DNs) under the Sip_Cluster switch with the following options:
      [TServer]
      	contact=*
      	dual-dialog-enabled=false
      	infra-class=2
      	make-call-rfc3725-flow=1
      	refer-enabled=false
      	sip-cti-control=talk,hold
      	sip-ring-tone-mode=1
      	use-contact-as-dn=true
      	use-register-for-service-state=false
    3. Create a Place object and map the DNs created.
    4. Create new Agents with username and password, under the "Persons" section.
    5. Map the Place to the agent.
  2. Once the objects are created successfully, follow the steps below to validate the voice microservices deployment..
    1. Register the DNs from Endpoints.
    2. Login/Logout the Agents from Workspace Web Edition or a similar application and change the states - Ready, Not Ready and Logout.
    3. Make few test calls between the agents.
    4. Perform other call functionalities like - hold/retrieve, conference, transfer, after call work, and so on.
    5. If Designer is available, load different strategies onto route points (external facing SBC Numbers) and validate if the inbound call made from PSTN is being routed to the agent/skill group configured.
  3. Additionally, you can also check the below after the deployment of voice microservices.
    1. Verify whether the Grafana dashboards of the voice microservices are updated with relevant data and they reflect the status of the services correctly.
    2. Check if the alerts and alarms are configured for the voice microservices and are active.
