# Wakdo - runner migrations + seed IN-CONTAINER (service compose one-shot wakdo-migrate).
|
|
#
|
|
# Applique, dans l'ordre lexicographique et de maniere IDEMPOTENTE :
|
|
# 1. db/migrations/*.sql (suivi : table schema_migrations)
|
|
# 2. db/seeds/*.sql (suivi : table seeds_applied)
|
|
# Relancer ne rejoue que les fichiers en attente (tracking par nom de fichier).
|
|
#
|
|
# Contrairement a db/migrate.sh (hote, via `docker exec`), ce runner tourne DANS
|
|
# un conteneur et se connecte a la base PAR LE RESEAU compose (DB_HOST). Il est
|
|
# lance par le service `wakdo-migrate` apres que `wakdo-db` soit healthy ; les
|
|
# services applicatifs (app/web) attendent sa COMPLETION (service_completed_successfully).
|
|
#
|
|
# But : `docker compose up` amene une stack COMPLETE et utilisable (schema + donnees
|
|
# de reference, dont l'admin bootstrap) en une seule commande, sans dependance a
|
|
# l'hote (Cr 7.c.4) -> remplace `make init`.
|
|
#
|
|
# Variables injectees par docker-compose : DB_HOST, DB_PORT, DB_NAME, DB_ROOT_PASSWORD.
|
|
# Root requis : migrations = DDL, seeds = INSERT de reference.
