Prerequisites to install Portworx Backup on TKGS
Tanzu Kubernetes Grid Service (TKGS) administrators can create deployments, StatefulSets, and DaemonSet (privileged pods) in the kube-system and default namespace, but cannot create in other namespaces. For example, Portworx Backup deployment in the central namespace fails, because Tanzu Kubernetes clusters include the default PodSecurityPolicy.
Before you deploy Portworx Backup, for example in the central namespace, you need to create a rolebinding for privileged and restricted workload deployment using the following commands:
kubectl create ns central
kubectl create rolebinding rolebinding-default-privileged-sa-ns_default --namespace=central --clusterrole=psp:vmware-system-privileged --group=system:serviceaccounts
