Templated metadata values

Some labels and annotations that MTO applies to managed namespaces need a value that differs per user or per tenant. Instead of a fixed string, you write a templated value — a placeholder that MTO replaces with real data when it reconciles the resource.

This page lists the templated values MTO supports today.

Supported templated values

{{ TENANT.USERNAME }}

Resolves to the username of the tenant member a namespace belongs to — one of the users listed under owners or editors in the Tenant. Use it where a per-user namespace needs a label or annotation carrying that user's name, as DevWorkspace sandboxes do.

Set it in either of two places, depending on how widely it should apply. The key name differs between the two, and both are correct:

Resource	Field	Applies to
Tenant	spec.namespaces.metadata.sandbox.labels / .annotations — singular sandbox	that tenant's sandboxes
IntegrationConfig	spec.metadata.sandboxes.labels / .annotations — plural sandboxes	every tenant's sandboxes, cluster-wide

Example:

annotations:
  che.eclipse.org/username: "{{ TENANT.USERNAME }}"   # the double quotes are required

The double quotes are not optional: unquoted, the leading {{ is read as the start of a YAML flow mapping, so the value fails to parse.
