GitOps Evolution Through the Lens of a Flux Maintainer
summary
Timeline starts in 2016 and traces concrete changes: monolithic v1 (one repo → one cluster) gives way to a controller-runtime rewrite in v2 and a split into focused controllers, driving community growth and 1 billion+ downloads; Flux runs in ~40MB memory enabling edge use; Flagger implements progressive delivery; OCI artifacts become a unified desired-state registry; Flux Operator provides declarative cluster bootstrap and fleet management for hundreds of clusters; the resource set API adds preview environments; the Flux MCP Server connects LLMs for troubleshooting, cross-cluster diffs and dependency graphs.
