fcrepo (Fedora Commons) is the linked data repository that Islandora uses to store digital objects and their metadata alongside Drupal. In an ISLE stack, fcrepo runs as a Docker service alongside the rest of the application. The fcrepo component controls whether the Fedora service, its volumes, and related Islandora configuration are part of your stack.

​
Check current state

sitectl component status
The output shows whether fcrepo is on, off, or drifted (meaning the project files no longer match the last applied state).

​
Enable fcrepo

sitectl component set fcrepo on
This adds the fcrepo service and its volumes back to docker-compose.yml and restores the Islandora configuration required to connect Drupal to Fedora.

​
Disable fcrepo

sitectl component set fcrepo off
This removes the fcrepo service and volumes from docker-compose.yml. A future docker compose up will no longer start Fedora.
Disabling fcrepo removes volumes from the Compose project definition. Existing fcrepo data on disk is not deleted immediately, but once you run docker compose down -v or similar, that data will be gone. Back up your fcrepo data before disabling on a site with content.

​
Sync fcrepo between environments

Copy the fcrepo database from one context to another: 
sitectl isle sync fcrepo --source museum-prod --target museum-local
This backs up the fcrepo database on the source context, stages it, and imports it into the target. Like the Drupal database sync, it asks for confirmation before importing. Pass --yolo to skip in automation. Use --fresh to always take a new backup rather than reusing one from today.

​
When to disable fcrepo

fcrepo adds significant resource requirements to a stack. You might disable it for:
  • Minimal local development — if you’re working on Drupal theme or module code that doesn’t interact with digital objects
  • Stacks that don’t use Islandora’s linked data features — some projects use ISLE as a Drupal hosting pattern but don’t use Fedora-backed objects
If you’re running a full Islandora installation with digital objects, fcrepo should be on.
