Triplet service - sitectl

Triplet is the default IIIF implementation in the LibOps ISLE template. It is managed by the ISLE plugin’s iiif and iiif-topology components rather than by a separate sitectl-triplet binary or lifecycle namespace.

Select Triplet

sitectl set iiif triplet

This adds the Triplet service, derivative cache, Traefik route, and Drupal IIIF URL expected by the Islandora stack. Use core Compose commands for its runtime lifecycle:

sitectl compose up -d
sitectl compose logs triplet
sitectl compose ps triplet

Local or Distributed

Keep Triplet in the Compose project with the default local topology:

sitectl set iiif-topology disabled

Point the production stack at an external Triplet endpoint while retaining local development wiring with:

sitectl set iiif-topology distributed --iiif-upstream-url https://iiif.example.edu

See IIIF components for the complete Cantaloupe/Triplet and topology contract.
