Installing Voice Gateway

A project administrator can install Voice Gateway on IBM Cloud Pak® for Data.

What permissions do you need to complete this task?
The permissions that you need depend on which tasks you must complete:
  • To install the Voice Gateway operators, you must have the appropriate permissions to create operators and you must be an administrator of the project where the Cloud Pak for Data operators are installed. This project is identified by the ${PROJECT_CPD_OPS} environment variable.
  • To install Voice Gateway, you must be an administrator of the project where you will install Voice Gateway. This project is identified by the ${PROJECT_CPD_INSTANCE} environment variable.
When do you need to complete this task?
If you didn't install Voice Gateway when you installed the platform, you can complete this task to add Voice Gateway to your environment.

If you want to install all of the Cloud Pak for Data components at the same time, follow the process in Installing the platform and services instead.

Important: All of the Cloud Pak for Data components in a deployment must be installed at the same release.

Information you need to complete this task

Review the following information before you install Voice Gateway:

Environment variables
The commands in this task use environment variables so that you can run the commands exactly as written.
  • If you don't have the script that defines the environment variables, see Setting up installation environment variables.
  • To use the environment variables from the script, you must source the environment variables before you run the commands in this task, for example:
    source ./cpd_vars.sh
Security context constraint requirements
Voice Gateway uses the restricted security context constraint (SCC).
Installation location
Voice Gateway must be installed in the same project (namespace) as the Cloud Pak for Data control plane. This project is identified by the ${PROJECT_CPD_INSTANCE} environment variable.
Storage requirements
You don't need to specify storage when you install Voice Gateway. For more information about available storage options, see Storage considerations.

Before you begin

This task assumes that the following prerequisites are met:

Prerequisite Where to find more information
The cluster meets the minimum requirements for installing Voice Gateway. If this task is not complete, see System requirements.
The workstation from which you will run the installation is set up as a client workstation and includes the following command-line interfaces:
  • Cloud Pak for Data CLI: cpd-cli
  • OpenShift® CLI: oc
If this task is not complete, see Setting up a client workstation.
The Cloud Pak for Data control plane is installed. If this task is not complete, see Installing the platform and services.
For environments that use a private container registry, such as air-gapped environments, the Voice Gateway software images are mirrored to the private container registry. If this task is not complete, see Mirroring images to a private container registry.
The vgw-tenantconfig-secret secret must exist in the project that you chose or created for the Voice Gateway installation. See Setting up Watson™ Assistant for Voice Interaction.

Procedure

Complete the following tasks to install Voice Gateway:

  1. Logging in to the cluster
  2. Installing the operator
  3. Installing the service
  4. Validating the installation
  5. What to do next

Logging in to the cluster

To run cpd-cli manage commands, you must log in to the cluster.

To log in to the cluster:

  1. Run the cpd-cli manage login-to-ocp command to log in to the cluster as a user with sufficient permissions to complete this task. For example:
    cpd-cli manage login-to-ocp \
    --username=${OCP_USERNAME} \
    --password=${OCP_PASSWORD} \
    --server=${OCP_URL}
    Tip: The login-to-ocp command takes the same input as the oc login command. Run oc login --help for details.

Installing the operator

The Voice Gateway operator simplifies the process of managing the Voice Gateway service on Red Hat® OpenShift Container Platform.

To install Voice Gateway, you must install the Voice Gateway operator and create the Operator Lifecycle Manager (OLM) objects, such as the catalog source and subscription, for the operator.

Who needs to complete this task?
You must be a cluster administrator (or a user with the appropriate permissions to install operators) to create the OLM objects.
When do you need to complete this task?
Complete this task if the Voice Gateway operator and other OLM artifacts have not been created for the current release.

If you complete this task and the OLM artifacts already exist on the cluster, the cpd-cli detects that you already have the OLM objects for the components at the specified release, the cpd-cli does not attempt to create the OLM objects again.

To install the operator:

  1. Create the OLM objects for Voice Gateway:
    cpd-cli manage apply-olm \
    --release=${VERSION} \
    --cpd_operator_ns=${PROJECT_CPD_OPS} \
    --components=voice_gateway
    • If the command succeeds, it returns [SUCCESS]... The apply-olm command ran successfully.
    • If the command fails, it returns [ERROR] and includes information about the cause of the failure.

What to do next: Install the Voice Gateway service.

Installing the service

After the Voice Gateway operator is installed, you can install Voice Gateway.

Who needs to complete this task?
You must be an administrator of the project where you will install Voice Gateway.
When do you need to complete this task?
Complete this task if you want to add Voice Gateway to your environment.

To install the service:

  1. Create the custom resource for Voice Gateway:

    cat <<EOF |oc apply -f -
    apiVersion: voicegateway.watson.ibm.com/v1
    kind: VoiceGateway
    metadata:
      name: voicegateway-cr       # This is the recommended name, but you can change it
      namespace: PROJECT_CPD_INSTANCE
    spec:
      license:
        accept: true
        license: Enterprise     # Specify the license you purchased
      replicas: 1                 # Set the number of desired replicas
      sslConfig:
        disableSslCertValidation: true
      resources:                  # Allocate available resources: 80% to mediaRelay and 20% to sipOrchestrator container
        sipOrchestrator:
          requests:
            cpu: "1.0"
            memory: 2Gi
          limits:
            cpu: "1.0"
            memory: 2Gi
        mediaRelay:
          requests:
            cpu: "0.5"
            memory: 1Gi
          limits:
            cpu: "0.5"
            memory: 1Gi 
    EOF

Validating the installation

When you create the custom resource, the Voice Gateway operator processes the contents of the custom resource and creates a deployment and pods. Voice Gateway is installed when the status of all the pods is Running.

To check the status of the installation:

  1. Get the status of the Voice Gateway pods:
    oc get pods --selector=app.kubernetes.io/name=ibm-voice-gateway-operator -o wide
Tip: To balance the load across multiple Voice Gateway pods, you need an external SIP load balancer or an SBC. The preceding command returns the IP addresses of the pods. You can add these IP addresses in your SIP load balancer or SBC device or you can directly call into them.
