# The dictionaries' image: the curator, keeping a server's dictionary files current
|
||
|
|
# from EDRDG's files of the day (`curate update`, the README). Built from the
|
||
|
|
# repository root (the build context), where the workspace's root pubspec and lockfile
|
||
|
|
# live:
|
||
|
|
#
|
||
|
|
# docker build -f halkyon_learn_curator/Dockerfile .
|
||
|
|
#
|
||
|
|
# A container of its own beside the server (deploy/compose.yaml, decided 2026-10-09):
|
||
|
|
# the curator (AGPL) never enters the server's image or process, and a conversion
|
||
|
|
# that fails can't touch the server. They share only the folder of files.
