1. GitOps Evolution Through the Lens of a Flux Maintainer Stefan Prodan Principal Engineer @ ControlPlane.io FluxCon NA 2025
2. GitOps - The Early Days @ C O N T R O L P L A N E I O
3. Flux v1 - GitOps Inception (2016 - 2019) @ C O N T R O L P L A N E I O
4. Flux v2 - GitOps Maturity (2020 - present) @ C O N T R O L P L A N E I O
5. Flagger - GitOps Progressive Delivery (2020 - present) @ C O N T R O L P L A N E I O
6. Flux v2 - Open Container Initiative (2022 - present) @ C O N T R O L P L A N E I O
7. Flux Operator GitOps on Autopilot Mode
8. Flux Operator - Overview @ C O N T R O L P L A N E I O The Flux Operator is designed to automate the lifecycle management of Flux components and to streamline the GitOps workflows for Kubernetes clusters. Highlights • Declarative cluster bootstrap (FluxInstance CRD) • Flexible cluster synchronisation (Git repos, OCI registries, S3 buckets) • Deep insight into the delivery pipelines managed by Flux • High-level abstractions built on top of Flux APIs (ResourceSet CRD) • AI-assistant GitOps with Flux MCP Server • Enterprise Edition with vulnerably remediation & automated patching
9. Flux Operator Declarative Cluster Bootstrap
11. Flux Operator - Gitless GitOps (2024 - present) @ C O N T R O L P L A N E I O
12. Flux Operator Dynamic Resource Composition
13. ResourceSet API @ C O N T R O L P L A N E I O The ResourceSet API offers a high-level abstraction for defining and managing Flux resources and related Kubernetes objects as a single unit. Features • Reduces the complexity of GitOps repositories • Multi-instance & multi-cluster provisioning for tenants and workloads • Advanced dependency management based on CEL expressions • Deploy app code and config changes made in Pull Requests to ephemeral environments for testing and validation
15. Flux MCP Server Agentic GitOps
16. Flux Operator - Model Context Protocol (MCP) Server @ C O N T R O L P L A N E I O The MCP Server connects AI assistants directly to your Kubernetes clusters running Flux Operator, enabling seamless interaction through natural language. Features • AI-powered troubleshooting & root cause analysis for issues with apps and infrastructure deployments • Cross-cluster comparison for Flux configuration and Kubernetes workloads • GitOps pipeline analysis, generation and refactoring • Engineers learn Flux concepts in the context of your actual infrastructure
