# Nix-built Paperless-ngx for ringtail (amd64).
|
||
|
|
#
|
||
|
|
# Replaces the from-source Dockerfile build (s6-overlay) with nixpkgs'
|
||
|
|
# paperless-ngx, which already bundles the full OCR/imaging closure
|
||
|
|
# (tesseract, ghostscript, imagemagick, qpdf, poppler, jbig2enc) and the
|
||
|
|
# NLTK data via wrappers — so the image stays lean.
|
||
|
|
#
|
||
|
|
# Unlike the upstream s6 image, this image does NOT run all processes
|
||
|
|
# itself. Paperless is multi-process; on ringtail it runs as four
|
||
|
|
# containers sharing this one image, each with a different command:
|
||
|
|
# web -> paperless-web (granian, the wrapper below)
|
||
|
|
# worker -> celery --app paperless worker
|
||
|
|
# beat -> celery --app paperless beat
|
||
|
|
# consumer -> paperless-ngx document_consumer
|
||
|
|
# plus a redis/valkey sidecar. The PYTHONPATH/granian invocation mirrors
|
||
|
|
# the nixpkgs paperless NixOS module's paperless-web service exactly.
|
||
|
|
#
|
||
|
|
# Self-pins nixos-unstable: stable nixpkgs lags at 2.19.6, while unstable
|
||
|
|
# carries 2.20.15 — a same-minor forward patch bump from the previous
|
||
|
|
# Dockerfile build (v2.20.13). The version assertion makes nix-build fail
|
||
|
|
# if a pin bump changes the version, forcing an explicit acknowledgment
|
||
|
|
# here and in service-versions.yaml (enforced by container-version-check).
