Project to take the first steps in the GitOps work philosophy using Flux CD.

The project shows how to configure a Kubernetes cluster based on GitOps. The organization of folders and services deployed correspond to a hypothetical cluster used for development or staging environments. This cluster configuration is not ready to be used in production.

To get more out of the repository it is recommended to have basic knowledge about the GitOps work philosophy. You can expand your knowledge on this topic through this link from the Weaveworks website.

The systems used during the exercise were: Git, Terraform, Docker, Flux CD y Kubernetes. The platform used to create the Kubernetes cluster is Digital Ocean, but Minikube can also be used.
