Manage Label Definitions
A Label Definition is the schema for a label key plus its value contract and on-delete policy. plexctl label define wraps /v1/label-definitions.
Prerequisites
- An authenticated session — see Log in with plexctl.
- The scope coordinate:
platform,domain:<uuid>, orproject:<uuid>. Pick the narrowest scope that covers every object you label.
Steps
Create a Definition
shell
plexctl label define create \
--scope domain:<domain-uuid> \
--key tier \
--type enum \
--on-delete block
# ID SCOPE QUALIFIED_KEY TYPE APPLICABLE_KINDS
# … domain:… tier enum …--type is checked against the value-schema kinds (boolean, numeric, regex, enum, string). --on-delete is block, cascade, or orphan — the policy applied when you later delete the Definition while Assignments still exist. block refuses the delete; cascade removes the Assignments with the Definition; orphan detaches them, leaving them readable per object (with a null parent definition) but excluded from Definition-scoped listings.
List, inspect, and update
shell
plexctl label define list --scope domain:<domain-uuid>
plexctl label define get <definition-uuid>
plexctl label define update <definition-uuid> --description "Service tier"scope, key, and immutable are frozen after creation.
Delete a Definition
shell
plexctl label define delete <definition-uuid> --yesDelete honours the Definition's own on_delete policy.
From the Console
Open the Domain's Label definitions page, use the per-row Delete action, and confirm in the modal. The delete is irreversible.
Two refusals surface inline rather than as a generic error:
- A
block-policy Definition that still has Assignments is refused — detach the Assignments first, or choose a Definition whose on-delete policy allows removal. - A system-managed Definition cannot be deleted.
Verification
shell
plexctl label define get <definition-uuid> --output json | jq '{local_key, value_schema}'
# {
# "local_key": "tier",
# "value_schema": { … }
