Database Inventory

Database Inventory

Maintain and update documentation of databases across AWS environments (QA, UAT, Production).

Inventory Location

Default inventory file: .stoobz/datagrip/databases.md

Workflow

1. Load Current Inventory

Read the existing inventory file to understand documented state:

cat .stoobz/datagrip/databases.md

2. Fetch Live Database List

For each environment, get current databases:

# Get RDS endpoint
ENDPOINT=$(aws rds describe-db-instances --profile <env> \
  --query 'DBInstances[0].Endpoint.Address' --output text)

# Get credentials from Secrets Manager
CREDS=$(aws secretsmanager get-secret-value --profile <env> \
  --secret-id <secret-name> --query 'SecretString' --output text)

# List databases (PostgreSQL)
PGPASSWORD=$(echo $CREDS | jq -r .password) psql \
  -h $ENDPOINT \
  -U $(echo $CREDS | jq -r .username) \
  -d postgres \
  -c "SELECT datname FROM pg_database WHERE datistemplate = false ORDER BY datname;" \
  -t

3. Compare and Report

Generate comparison between documented and live state:

4. Update Inventory

Update the markdown file with:

• Current database list per environment
• Last updated timestamp
• Any notes about changes

Inventory Format

# Database Inventory

Last updated: 2026-02-02

## QA Environment

| Database  | Purpose          | Owner       | Notes        |
| --------- | ---------------- | ----------- | ------------ |
| orders_db | Order processing | orders-team | Primary OLTP |
| users_db  | User accounts    | auth-team   |              |

## UAT Environment

| Database  | Purpose          | Owner       | Notes        |
| --------- | ---------------- | ----------- | ------------ |
| orders_db | Order processing | orders-team | Mirror of QA |

Commands

Full Sync

Fetch all environments and update inventory:

1. Authenticate to each environment
2. List all databases
3. Compare with inventory
4. Report changes
5. Prompt to update file

Quick Check

Compare single environment without updating:

# Just show differences, don't modify inventory

Integration with aws-env-discovery

This skill complements aws-env-discovery:

• Use aws-env-discovery to get connection details
• Use database-inventory to maintain documentation

Safety Notes

• Always show diff before updating inventory file
• Preserve manual annotations (Purpose, Owner, Notes columns)
• Back up inventory before major updates
