Key Configuration Fields

  • core_service: Set to decypharr, nzbdav, or a list of both to enable DUMB integration.
  • use_neutarr: Opt this instance into NeutArr automation.
  • use_profilarr: Opt this instance into Profilarr auto‑linking.
  • port: Web UI port (default 7878).
  • pinned_version: Optional version pin for Radarr updates.
  • repo_owner / repo_name: GitHub repo used for releases or branch builds.
  • release_version_enabled / release_version: Use GitHub releases (e.g., latest, nightly, prerelease, or a tag).
  • clear_on_update: Clear the install directory before updating.
  • exclude_dirs: Directories to preserve when clearing.
  • platforms: Build platforms (auto‑defaults to ["dotnet"] when using branches).
  • config_dir, config_file, log_file: Paths for config and logs.

Repo-based installs and updates

Radarr now supports the same repo‑based controls as other DUMB services.

  • GitHub releases: Set release_version_enabled: true with a valid repo_owner/repo_name.
  • Default updater: Leave release_version_enabled: false to use the standard Arr updater.

GitHub sources take priority when enabled and are not a fallback. pinned_version only applies to the traditional Arr updater.

Integration with DUMB

  • For Decypharr integration, set core_service to decypharr and follow the Decypharr guide.
  • For NzbDAV integration, set core_service to nzbdav and follow the NzbDAV guide.
  • For combined workflows, set core_service to ["decypharr", "nzbdav"].
  • Use Prowlarr to centrally manage indexers and sync them to Radarr.
  • DUMB enables Arr folder permission updates and applies permissions to configured root folders during integration.
  • See Core Service Routing for how core_service affects automation.
