Flux

Name: Flux
Availability: InStock

A standalone path through Flux, the GitOps toolkit built as a set of composable Kubernetes controllers. Beginner covers the controller model, bootstrapping, GitRepository sources, and Kustomization reconciliation. Intermediate builds real delivery: HelmRelease and the helm-controller, dependencies and health, image automation, and notifications/alerts. Advanced goes deep: multi-tenancy and RBAC, secrets (SOPS/SealedSecrets), hardening the toolkit and supply chain, and Flux vs Argo CD. Real CRDs and CLI output throughout; each level ends with a self-test feeding a rotating final exam.
