Apply both the Fleet GitRepo commands from below to the local cluster. I find it easiest to use the kubectl shell inside of the Rancher Manager.
Add a Cluster Label to each cluster: Rancher Manager UI -> Hamburger Menu -> Continuous Delivery -> Clusters -> Select Cluster & Edit Labels
For Rancher Longhorn, use the label: longhorn=enabled
For Rancher NeuVector, use the label: neuvector=enabled
For Rancher Monitoring, use the label: monitoring=enabled
Fleet Local and Fleet Default
### Adds the GitRepo(s) to the local cluster.
kubectl apply -f https://raw.githubusercontent.com/nnewc/fleet/main/gitrepo-local.yaml
### Adds the GitRepo(s) to all downstream cluster(s).
kubectl apply -f https://raw.githubusercontent.com/nnewc/fleet/main/gitrepo-default.yaml
