Prerequisites for Web Services and Applications

To work with Web Services and Applications, your system must meet the software requirements established in the Genesys Supported Operating Environment Reference, and meet the minimum requirements outlined on this page.

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

Hardware requirements

JM: I just copied these values from another product to use as a starting point.

  • OS: CentOS 7 (64 Bit) or RHEL 7 (64 Bit)
  • RAM: 16Gb
  • CPU: 4 cores minimum
  • Disk space: 20Gb free space minimum required, 50Gb recommended

Software requirements

Docker

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

Kubernetes

You'll also need to install the latest release of Kubernetes, which is an open-source system for automating deployment, scaling, and management of containerized Docker applications. It's sometimes called a container orchestration system.

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.

Openshift

  • RHEL7
  • GlusterFS(Red Hat Container storage)
  • Openshift licenses
  • A passwordless ssh root account, with operator's keys added


DNS Requirements

All of the services, either cluster-wide, infrastructure or GWS-applications ingresses require DNS names to be pre-populated to get access to and for host-based naming virtualization. 

    XX.XX.XX.XX   grafana.gke.local
    XX.XX.XX.XX   consul.gke.local
    XX.XX.XX.XX   active.gke.local
    XX.XX.XX.XX   test.gke.local

Persistent Storage Requirements

  • Openshift : the GlusterFS storage can be pre-populated manually.
  • GKE : No specific configuration is required.
  • No storage : Set the PERSISTENT_STORAGE=false in the environment file.
