FluxCD Has a Free API: GitOps Toolkit for Kubernetes at Scale

#gitops #cicd #devops #kubernetes

Why FluxCD

Flux is a CNCF GitOps toolkit — modular, composable controllers that sync Git repos, Helm charts, OCI artifacts, and Kustomize overlays to Kubernetes. It is the GitOps standard alongside Argo CD.
