Every infrastructure tool has a founding myth, a first commit pushed to solve a problem nobody else would. These are the origin stories — the initial need, the people, the pivots that almost killed the project, and the crises that forged it — told through a sourced timeline.

2018–presentA Kubernetes-community fusion of three rival DNS controllers, ExternalDNS became the default way Kubernetes services get DNS records while never leaving 0.x.
2017–presentBuilt inside Weaveworks as a deployment daemon called fluxy, Flux gave the industry the word GitOps — then survived its maker's collapse under CNCF governance.
2016–presentBorn as a sample controller inside the kubernetes/contrib repo, Ingress NGINX became the default traffic entry point for half the cloud-native world — then was archived after years of one-maintainer heroics.
