Prerequisites for Web Services and Applications

When your environment is ready, you can deploy Web Services and Applications.

Hardware Requirements

Docker Compose (Non-Production Lab Deployment only)

• RAM: 16 GB
• CPU: 2 cores minimum
• HDD: 100 GB

Kubernetes (Minimum sizing for Non-Production Lab Deployment only)

• Nodes: 3 nodes (Virtual Machines)
• RAM: Approximately 32 GB for each node (96 GB in total)
• CPU: 10 cores for each node (30 cores in total)
• HDD: 100 GB for each node

Important

Contact your Genesys representative and the Architecture team for guidance about recommended sizing for your specific production deployment.

Software Requirements

Olena's Note: CentOS latest per GAPI-25169 for Dec 2020 release

• CentOS-7 operating system CentOS latest

Docker Compose (Non-Production Lab Deployment only)

• Docker — use the latest stable version.
• Docker Compose — use the latest stable version.

Web Services and Applications is installed using Docker containers. A Docker deployment provides a complete self-contained environment, so that you do not need to manually configure ports or address compatibility issues. All of that is taken care of ahead of time, and the completed Docker containers work together seamlessly upon deployment.

Refer to the Docker and Docker installation documentation for more information about how to install and set up the latest releases.

Kubernetes

* CentOS-7 operating system

Kubernetes cluster:

• Kubernetes 1.16 or 1.17
• Helm 3.x

You must also install the kubectl tool which corresponds to the Kubernetes cluster version.

Rancher Kubernetes Engine (RKE) cluster:

• To deploy the RKE cluster, refer to RKE Kubernetes Installation.

The exact installation procedure for Kubernetes varies significantly depending on numerous factors, including the type of machines in your environment (these could be real machines, virtual machines, or cloud machines), operating system, networking model, planned load, and Kubernetes version.

Refer to the Kubernetes installation documentation for more information about how to install and set up Kubernetes for your environment.
