|
# shared-memory — external Postgres override.
|
||
|
|
#
|
||
|
|
# Use this override when you want to point the app at a managed Postgres
|
||
|
|
# (AWS RDS, GCP Cloud SQL, Azure Database for PostgreSQL, your own VM, ...)
|
||
|
|
# instead of the bundled `db` container.
|
||
|
|
#
|
||
|
|
# Invocation (always together with the base file):
|
||
|
|
#
|
||
|
|
# docker compose -f docker-compose.yml -f docker-compose.external-db.yml up -d
|
||
|
|
#
|
||
|
|
# The caller MUST set `DATABASE_URL` explicitly in `.env` so that `migrator`
|
||
|
|
# and `app` know where to connect. The `POSTGRES_*` variables are not used
|
||
|
|
# in this mode (the bundled `db` service is disabled below). Example:
|
||
|
|
#
|
||
|
|
# DATABASE_URL=postgres://memory:STRONG_PASSWORD@your-rds.region.rds.amazonaws.com:5432/memory?sslmode=require
|
||
|
|
#
|
||
|
|
# The DB user needs privileges to `CREATE EXTENSION` for pgvector, pg_trgm,
|
||
|
|
# and pgcrypto on first run — on RDS that means the `rds_superuser` role, or
|
||
|
|
# pre-create the extensions yourself. See README "External Postgres".
