### Database Storage
|
||
|
||
**Primary Location:** `/mnt/psql-data/`
|
||
|
||
All PostgreSQL databases are stored on a dedicated disk for performance and data isolation.

### PostgreSQL Management Commands
|
||
|
||
```bash
|
||
# Connect to PostgreSQL
|
||
docker exec -it postgres-main psql -U aimpress_admin
|
||
|
||
# Inside psql:
|
||
\l # List all databases
|
||
\du # List all users
|
||
\dt # List tables in current database
|
||
\c database_name # Connect to database
|
||
\q # Exit
|
||
|
||
# Backup single database
|
||
docker exec postgres-main pg_dump -U aimpress_admin <database> | \
|
||
gzip > /mnt/backups/db-$(date +%Y%m%d).sql.gz
|
||
|
||
# Backup ALL databases
|
||
docker exec postgres-main pg_dumpall -U aimpress_admin | \
|
||
gzip > /mnt/backups/postgres-all-$(date +%Y%m%d).sql.gz
|
||
|
||
# Restore database
|
||
gunzip < /mnt/backups/backup.sql.gz | \
|
||
docker exec -i postgres-main psql -U aimpress_admin -d <database>
|
||
|
||
# Check database sizes
|
||
docker exec postgres-main psql -U aimpress_admin -c \
|
||
"SELECT pg_database.datname, pg_size_pretty(pg_database_size(pg_database.datname)) \
|
||
FROM pg_database ORDER BY pg_database_size(pg_database.datname) DESC;"
|

### Database Users

### Change Database Password

NEW_PASS=$(openssl rand -base64 32)
|
||
echo "New password: $NEW_PASS"
|
||
|
||
# 2. Change in PostgreSQL
|
||
docker exec postgres-main psql -U aimpress_admin -c \
|
||
"ALTER USER <username> WITH PASSWORD '$NEW_PASS';"
|
||
|
||
# 3. Save to Vault
|
||
export VAULT_ADDR="http://127.0.0.1:8200"
|
||
export VAULT_TOKEN="hvs.jYguDdf2IzobXG8b9QWyATV8"

# 4. Update application config
|
||
cd /opt/<service-path>
