-- dashboard_ro_role.sql — dedicated read-only LOGIN role for dashboard_api.
|
||
|
|
--
|
||
|
|
-- Run as the postgres SUPERUSER (CREATE ROLE), NOT via run_migrations.py (which
|
||
|
|
-- connects as the app role and may lack CREATEROLE). Apply with
|
||
|
|
-- scripts/bootstrap_dashboard_ro.sh, which supplies the password as the psql
|
||
|
|
-- variable :ro_pw from a host-only 0600 file — so no secret lives in this repo.
|
||
|
|
--
|
||
|
|
-- Purpose: a least-privilege role that can serve the FULL dashboard_api read
|
||
|
|
-- surface, so it backs BOTH the staging instance now (stage 1) AND the live prod
|
||
|
|
-- connection later (stage 2 — migrate fleetapi.rahamafresh.com off the app role).
|
||
|
|
-- It therefore grants exactly what the API reads:
|
||
|
|
-- * SELECT on reporting.* and tracksolid.* (tables + views)
|
||
|
|
-- * SELECT on the reporting.v_trips MATERIALIZED VIEW — matviews are NOT
|
||
|
|
-- covered by GRANT ... ON ALL TABLES, so it must be named explicitly
|
||
|
|
-- * EXECUTE on the reporting.fn_* map functions (fn_live_positions, etc.)
|
||
|
|
-- * DEFAULT PRIVILEGES so future objects created by the migration role are
|
||
|
|
-- auto-readable ("dynamic" — no re-grant when we add views)
|
||
|
|
-- Read-only: no INSERT/UPDATE/DELETE and not the matview owner, so dashboard_ro
|
||
|
|
-- can never write or REFRESH. Idempotent -> safe to re-apply (also rotates pw).
