# docker-compose.yml — PgBouncer in front of timescale_db.
|
||
|
|
# ─────────────────────────────────────────────────────────────────────────────
|
||
|
|
# Deploy:
|
||
|
|
# 1. Apply auth_setup.sql to the DB as postgres (creates pgbouncer_auth + lookup fn).
|
||
|
|
# 2. Generate pgbouncer/userlist.txt (see userlist.txt.example).
|
||
|
|
# 3. Put this stack on the SAME docker network as timescale_db so `timescale_db`
|
||
|
|
# resolves (the tracksolid stack's network — the one with the 10.0.15.x addrs).
|
||
|
|
# 4. `docker compose -f pgbouncer/docker-compose.yml up -d`
|
||
|
|
# 5. Repoint each app's DSN host:port from timescale_db:5432 → pgbouncer:6432
|
||
|
|
# (same dbname/user/password) and redeploy it. Migrate the SUPERUSER app pools
|
||
|
|
# first — they are the heaviest consumers.
