Tackling Configuration Management at Scale with Flux, CUE and OCI

Explore a conference talk on managing large-scale configuration for IoT devices using Flux, CUE, and OCI at Cisco. Discover how Cisco's IoT platform handles 245M+ devices across global Kubernetes clusters with GitOps and Flux. Learn about the challenges of configuration management at scale and Cisco's innovative approach using open-source tools like Flux, Helm, OCI, CUE, and Timoni. Examine their GitOps implementation featuring a 3-tier Git repository layout and how CUE integrates with Flux for configuration validation and secret management. Understand how this approach scales Flux-managed Helm releases across cluster fleets while promoting collaboration between development, testing, build, release, and SRE teams. Gain insights from Flux core maintainer Stefan Prodan on leveraging OCI artifacts to address complexities in managing Git repository layers and learn about Timoni, a Kubernetes package manager that combines CUE's features for robust deployments.
