FluxCD
FluxCD is a GitOps tool that automates the deployment of containerized applications to Kubernetes clusters. It continuously monitors Git repositories for changes to Kubernetes manifests and Helm charts, then automatically synchronizes those changes to the target clusters. This ensures that the cluster state matches the desired configuration defined in version control.
Developers should use FluxCD when implementing GitOps workflows for Kubernetes, as it provides declarative, automated deployment and configuration management. It's particularly valuable in production environments for ensuring consistency, enabling rollbacks via Git history, and reducing manual intervention in deployments. Use cases include multi-cluster management, continuous delivery pipelines, and maintaining compliance through auditable Git-based changes.
