11. Environmental Needs

11.1 Hardware Needs

Four physical or virtual machines with identical hardware specifications are required to run the Kubernetes cluster. Each machine must have a minimum of 2 GB of memory and the following minimum CPU requirements.

1. 2 AWS vCPU
2. 2 GCP Core
3. 2 Azure vCore
4. 2 Hyperthread on a bare-metal Intel processor with Hyperthreading

A single physical or virtual test machine is required to run the tests and interface with the Kubernetes cluster. It is recommended that the machine's CPU is at minimum an Intel Core i5-3330 or equivalent.

The test machine must be able to communicate with the four physical machines over a public or private network using HTTP.

11.2 Software Needs

The four machines must meet the following software requirements.

1. Kubernetes cluster. A Kubernetes cluster running version 1.8.5 must be deployed on the machines. Documentation on setting up a Kubernetes cluster can be found here.
2. Helm. The Helm server must be initialized on the Kubernetes cluster using the helm init command after installing the Helm client and kubectl on the single test machine.

The single test machine must meet the following software requirements.

1. kubectl. kubectl must be installed to interface with the Kubernetes cluster. Documentation on setting up kubectl can be found here.
2. Helm. The Helm client must be installed. Documentation on setting up the Helm client can be found here.
3. Python 3.0.

11.3 Description of Actual Testing Environment

For executing the tests, Kubernetes Engine on the Google Cloud Platform will be utilized. The node pool will be setup in the us-central1-a zone with autoscaling disabled. Four Compute Engine VM instances with 2 vCPU cores and 4 GB of memory will be utilized. The cluster will be setup to use Kubernetes v1.8.5.

To execute the tests on the Kubernetes cluster, a Mid 2014 13-inch MacBook Pro running macOS Sierra Version 10.12.6 with 16 GB of memory and a 3 GHz Intel Core i7 processor will be utilized. The University of Saskatchewan's wireless network will be used to perform the tests.
