RancherProjector

---

RancherProjector is a short program, meant to be run in the Rancher Management Cluster, that will gather the Rancher Projects defined and post them to a Rancher-Selector Endpoint, deployed in a downstream cluster. Obviously, RancherProjector, needs RancherSelector to work: https://github.com/wrkode/rancher-selector

information

RancherProjector will watch the Rancher Management Cluster Projects. On event such as creation/update/deletion of Projects and Projects Annotations, RancherProjector will hit RancherSelector API on the downstream cluster with POST/Delete requests. The reasoning behind this is that Rancher Projects do not exist as CRD/Objects in the Rancher Downstream clusters. Therefor (at the time of this writing) there's no way to use the user-defined annotations defined at Project creation. The counterpart of RancherProjector, RancherSelector, will create a ConfigMap named rancher-data in the downstream cluster, in Namespace kube-system. this ConfigMap will contain all projects and annotations of all projects of the downstream cluster.

Usage

Important: make sure that RancherSelector is already deployed in all downstream clusters.

• clone this repository and cd into the root directory.
• create a non-scoped Rancher API Bearer Token.
• create a secret in the kube-system namespace named rancher-projector-secret with key:value token=<yourBearerToken>.
• Adjust file deployment.yaml as required.
• Deploy RancherProjector with kubectl apply -f deployment.yaml.
• Check in the downstream cluster namespace kube-system if ConfigMap rancher-data has been created.
