Prerequisites

Hardware Requirements

The solution can be deployed at a Kubernetes cluster with a minimal size of 3 nodes with an overall amount of 64 GB RAM. Recommended hardware requirements for each Kubernetes node:

• Nodes: 3 nodes (Virtual Machines)
• RAM: Approximately 22 GB for each node (64 GB in total)
• CPU: 15 cores for each node (45 cores in total)
• HDD: 100 GB for each node

Software Requirements

• OS: CentOS-7

Kubernetes cluster:

• Rancher Kubernetes Deployment
• Client-side utilities installed at deployment host:

  • Kubectl tool
  • Helm

Workspace Web Requirements

• Browser:

  • Google Chrome 75+
  • Mozilla Firefox 68+
  • Firefox ESR 60.9
  • Microsoft Internet Explorer 11

Configuring Web Services Applications

To configure Web services and applications, refer to Configuring Web Services and Applications.

Deploying GWS

Implementation Steps

Unpack installation package (Example: IP_HTCCDev_9000197b1_ENU_dockerlinux.zip file) and navigate to "ip" folder which should contain following files: gws-microservices.tgz exported microservices in tar.gz format (e.g. gws-platform-configuration_9.0.000.42.tar.gz) Unpack gws-microservices.tgz archive to /opt/genesys/gws directory.

mkdir -p /opt/genesys/gws
tar xvf gws-microservices.tgz -C /opt/genesys/gws

Populate the Docker images (presented in *.tar.gz format) from installation package to your corporate docker registry.

for i in *.tar.gz; do /opt/genesys/gws/kubernetes/bin/push-containers-to-local-registry.sh $i %corporate_registry_address% --push; done

Important

This script must be run with Docker capable privileges and you must login to your registry before pushing.

Variable	Value	Description
REGISTRY	NA	Corporate docker registry, which is accessible from all Kubernetes nodes.
GWS_DOMAIN	"onpremiselab.com"	Domain associated with this contact center.
LOCATION	/USW2	Location of Configuration Server Note: The GWS Cluster Application object (typically named CloudCluster) in the Configuration Database must be configured with a specified location for each connection to Genesys servers, like Configuration Server, Stat Server, T-Server, and so on. This setting defines which server instance is visible by the GWS node based on its position in the GWS Cluster.
CS_USERNAME	default	Username to connect to Configuration Server.
CS_PASSWORD	password	Password to connect to Configuration Server.
CS_APPNAME	Cloud	Application name to connect to Configuration Server.
CS_ADDRESS	127.0.0.1	Address of primary Configuration Server.
CS_PORT	8888	Port of primary Configuration Server.
CS_BACKUP_ADDRESS	127.0.0.1	Address of backup Configuration Server.
CS_BACKUP_PORT	8888	Port of backup Configuration Server.
CS_TENANT	Environment	Configuration Server's tenant name.
GWS_REDIRECT_URI	http://onpremiselab.com	Specifies an array by using double quotes and comma to separate values with no whitespace between. Used as part of OAuth authentication flow.
ingressTlsEnable	false	Enables Ingress secured endpoint configuration for Web Service and Applications.
POST_DEPLOY_UPDATE	true	Enable post deploy procedure, which creates default Genesys environment, contact center and OAuth client.
DEPLOY_POSTGRES	false	Enable PostgreSQL deployment procedure in same namespace as Web Services and Applications. Note: For Lab deployments only.
POSTGRES_ADDR	postgres	Address of PostgreSQL installation Note : If DEPLOY_POSTGRES set to true, default value should be kept.
POSTGRES_DB	gws_environment	PostgreSQL database nameNote : If DEPLOY_POSTGRES set to true, default value should be kept.

POSTGRES_PASS	gws_env_password	PostgreSQL user passwordNote : If DEPLOY_POSTGRES set to true, default value should be kept.
DEPLOY_REDIS	false	Enable Redis cluster deployment procedure in same namespace as Web Services and Applications. Note: For Lab deployments only.
REDIS_ADDR	redis-cluster:6379	Address of Redis cluster installation Note : If DEPLOY_REDIS set to true, default value should be kept.
DEPLOY_ELASTICSEARCH	false	Enable ElasticSearch cluster deployment procedure in same namespace as Web Services and Applications. Note: For Lab deployments only.
