Customize Trident operator deployment

Contributors juliantap

The Trident operator allows you to customize Astra Trident installation using the attributes in the TridentOrchestrator spec.

If you want to customize the installation beyond what TridentOrchestrator arguments allow, you should consider using tridentctl to generate custom YAML manifests that you can modify as needed.

Warning spec.namespace is specified in TridentOrchestrator to signify which namespace where Astra Trident is installed. This parameter cannot be updated after Astra Trident is installed. Attempting to do so causes the TridentOrchestrator status to change to Failed. Astra Trident is not intended to be migrated across namespaces.
