FluxCD 101 with Hands-On Labs from Udemy

GitOps is a framework where the entire code delivery process is controlled via the Git repository. GitOps operators such as Flux can automatically pull the desired state from Git and apply them to Kubernetes targets.

Some of the Flux's features are,

Flux provides GitOps for both applications and infrastructure
Just push to Git and Flux does the rest
Flux is designed with security in mind and provides ways to encrypt/decrypt secrets
Flux can work with all common Kubernetes tooling like Kustomize, Helm, RBAC, and OPA policies
Flux can send alerts and notifications to 3rd party products

I will present every topic in a simple, visual, and easy way.

we will first understand the topic by going through animated slides
we will do practical demos for every topic
we provide a GitHub repository and downloadable material with manifests and source code
we provide hands-on exercises using OOTB Lab Environments
