Learning project for Azure Kubernetes Service, Helm, Kafka and Azure Table Storage. Load testing with Locust.

Setup

Install Python3 using chocolatey (as administrator)

choco install python3

Create a virtual environment called venv

python -m venv venv

Activate the virtual environment

venv\Scripts\activate.bat

Install the requirements in requirements.txt

pip install -r requirements.txt

Running

Open a command prompt with the virtual environment activated. Shortcut to do this is to just double-click "!_SHELL.cmd".

Run flask locally

cd containers\uwsgi-server
python server.py

Or run the app using Kubernetes, with uWSGI as the app server and NGINX as the reverse proxy.

kubectl apply -f kubernetes.yaml

Smoke Testing

Run one of the following curl commands (Kubernetes):

curl localhost:30001
curl localhost:30001/time

Run one of the following curl commands (Flask dev):

curl localhost:5000
curl localhost:5000/time

Load Testing

Create another virtual environment for the locust test and install requirements. Then run:

cd load-test
python -m locust

The web interface will spin up and is locally accessible at http://localhost:8089

Monitor the horizontal pod autoscaler and the nodes with the following:

kubectl get hpa -w
kubectl get nodes -w
