GitOps at Scale
summary
Rancher Fleet is presented as a GitOps system that scales to up to a million clusters by installing a lightweight fleet agent on each cluster and using a central fleet controller in the Rancher management server. It deploys bundles (Kubernetes manifests or Helm charts) from Git repositories (GitHub/GitLab/Bitbucket), targets deployments to cluster groups or workspaces, and uses a pull-based GitOps approach so edge k3s devices update when they reconnect. A Continental case is cited with about 80% faster production migrations/upgrades.
