Hi!

Rancher 2.7 seems to have change to a random id since
rancher/rancher@cc9f7ee

Make it much harder to do project and fix permissions for the created clusters.

Still a problem on Rancher v2.7.5

Is there a workaround? How is the Rancher cattle-management cluster name generated? Simply truncating the sha256sum of the release namespace concatted with / + cluster name is no longer valid.

clusterroletemplatebinding.yaml

  1 {{ $root := . }}                                                                                                  
  2 {{- range $index, $member := .Values.clusterMembers }}
  3 apiVersion: management.cattle.io/v3
  4 clusterName: c-m-{{ trunc 8 (sha256sum (printf "%s/%s" $root.Release.Namespace $root.Values.cluster.name)) }}
  5 kind: ClusterRoleTemplateBinding
  6 metadata:
  7   name: ctrb-{{ trunc 8 (sha256sum (printf "%s/%s" $root.Release.Namespace $member.principalName )) }}
  8   namespace: c-m-{{ trunc 8 (sha256sum (printf "%s/%s" $root.Release.Namespace $root.Values.cluster.name)) }}
  9 roleTemplateName: {{ $member.roleTemplateName }}
 10 userPrincipalName: {{ $member.principalName }}
 11 principalId: {{ $member.principalId }}
 12 {{- end }}

Example deploying cluster template:

Valid Namespace: c-m-ppthnkp5

Output:

$ helm  upgrade -i  -n fleet-default --values ./charts/values.yaml $(CLUSTER) ./charts
