Prerequisites for Web Services and Applications

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

Hardware Requirements

Docker Compose (Labs only)

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

Kubernetes

  • 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

Software Requirements

Docker Compose (Labs only)

  • OS: CentOS-7
  • Docker. Please use the latest stable version.
  • Docker Compose. Please 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

  • OS: CentOS-7

Kubernetes cluster:

  • Kubernetes engine N-2 releases, where N is the current release (Example: 1.14)
  • Helm 3.x

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

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.

Infrastructure Components
