Multi K8s

This project is a designed to explore kubernetes deployments using a highly overly complicated architecture to allow for creating many pods and using multiple different technologies.

NOTE: This project is not being updated and may use old / insecure packages. It should be used for reference only.

A high level overview of the architecture is down in the image below.

What it does

Once deployed the multi-k8s website allows users to enter a number and calculates the Fibonacci number at that index.

The user-facing deployment consits of the following:

• The multi-client — a simple ReactJS site with the form to enter a new index and shows the results of the calculations.
• The multi-server — an express server that acts as the REST API, reading and writing to the postgres database and redis instance.
• The multi-worker — a nodejs worker that subscribes to inserts into the redis instance and calcualtes the Fibonacci number for the given index, saving the result back into redis.

Also created:

• A postgres database with a persistant volume claim
• A redis instance
• NGINX ingress routing requests to the multi-client or multi-server depending on the path component of the request.

Google Cloud deployment

This project is automatically deployed to Google Cloud using Travis CI

On Google Cloud the deployment makes use of a Google Cloud Load balancer
