Register cluster in Rancher

[jp-gouin]

After creating a cluster in shared mode, I tried to register it in Rancher.
The registration worked but fleet failed

Warning  ProviderCreateFailed  9m50s (x15 over 20m)  k3k-single-server-test3-kubelet/pod-controller  Pod "fleet-agent-0-cattle-fleet-system-single-server-test3-666-e264d" is invalid: spec.initContainers[0].volumeMounts[0].name: Not found: "kube-api-access-94hl2

helm-operation pods fails with
