add optional read-replica database to docker compose#31
Conversation
Updated `docker-compose.yml`: The main db service to prepare it for replication. It now starts with the required Postgres flags (`wal_level=replica`) and mounts the new `init-replication.sh` script. Added `init-replication.sh`: Helper script to run inside the main db container on startup and add a security rule to `pg_hba.conf`. This rule is necessary to give the new replica permission to connect and clone the database. Added `docker-compose.replica.yml`: New docker compose file defines the new `db-replica` service, which clones the primary database and keeps itself in sync.
