This is an example repository that demonstrates how to use GitOps to create GKE (Google Kubernetes Engine) clusters on demand, register them to a Fleet, and bootstrap them with FluxCD.

Once the newly created Fleet clusters are bootstrapped with FluxCD, they will automatically begin to synchronize all GKE cluster platform configurations and application tenant configurations.

This Git repository contains the following directories.

📁 apps             # Example of a application operators configuration
📁 hack             # Directory for scripts
📁 kubernetes       # Example of a platform operators configuration
├─📁 clusters       # FluxCD cluster installation
├─📁 namespaces     # Platform tooling and configuration
└─📁 tenants        # Teams onboarded as tenants

The below showcases the collection of open-source solutions currently implemented in the cluster. Each of these components has been documented, and their deployment is managed using FluxCD, which adheres to GitOps principles.
