1. #KubeCon #CloudNativeCon Flux MCP AI-Assisted GitOps Stefan Prodan - ControlPlane Flux core maintainer
2. Flux - GitOps Continuous Delivery
3. Flux Operator - Gitless GitOps
4. GitOps - Challenges Monorepo complexity vs Config repo sprawl You’ll be reading, writing and reviewing LOTS of YAML You’ll become an YAML engineer Drift correction signal-to-noise ratio can be low
8. Flux MCP - Overview The MCP Server connects AI assistants directly to your Kubernetes clusters running Flux Operator, enabling seamless interaction through natural language. Features • GitOps pipeline analysis, generation and refactoring • Engineers learn Flux concepts in the context of your actual infrastructure • Cross-cluster comparison for Flux configuration and Kubernetes workloads • AI-assisted troubleshooting & root cause analysis
9. Flux MCP - Local Mode
10. Flux MCP - Security Considerations The Flux MCP Server is designed with security in mind: • Operates with your existing kubeconfig permissions • Supports service account impersonation for limited access • Masks sensitive information in Kubernetes Secret values • Provides a Kubernetes read-only mode for observation without affecting the cluster state When running the MCP Server in-cluster with Streamable HTTP, cluster-admins can configure OIDC-auth, Kubernetes group impersonation with fine-grained access control.
11. Flux MCP - Tools Read Tools • get_flux_instance / get_kubernetes_resources / get_kubernetes_api_versions • get_kubernetes_logs / get_kubernetes_metrics • search_flux_docs Write Tools • reconcile_flux_source / suspend_flux_reconciliation / resume_flux_reconciliation • apply_kubernetes_manifest / delete_kubernetes_resource • install_flux_instance
12. Flux MCP - Remote Mode
13. Flux MCP - Auth Config
14. Flux MCP - Preview Environments
15. Agentic AI - Incident Management The AI assistants leveraging the Flux MCP can reduce the mean time to resolution (MTTR) during incidents with contextual analysis and actionable remediation steps. • Trace issues from high-level GitOps resources like ResourceSets, Helm Releases, and Kustomizations all the way down to Kubernetes pods • Correlate events, logs, and configuration changes to identify the source of failures in GitOps pipelines
16. Flux MCP - Roadmap Highlights Better docs indexing Enhanced docs search tool with embedded index for air-gapped environments. SSO built-in integration Native support for Google, GitHub and Microsoft Entra ID Tool usage policies Fine-grained tool allow list for cluster admins https://fluxcd.control-plane.io/mcp/
