Dynamic Secrets and Rotation
Generate short-lived, auto-rotating PostgreSQL credentials for the real TaskFlow backend with Vault's database secrets engine, then manage leases and compliance controls.
Lab Overview
🛠Lab from the Platform Engineering Bootcamp. Used in Week 18. Bootcamp landing page: https://academy.tekanaid.com/bootcamps/platform-engineering-bootcamp Parent course(s):
- Week 18: Secrets Management with HashiCorp Vault (slug: secrets-management-vault)
This lab runs the real TaskFlow backend and its PostgreSQL database (the same TaskFlow project that grows across all 21 weeks of the bootcamp). You configure Vault's database secrets engine against taskflow_db, feed a dynamically generated credential to the real backend, and prove it connects, then rotate, manage leases, and enforce compliance controls against those live credentials.
Master dynamic secrets management with Vault by generating short-lived PostgreSQL credentials for TaskFlow, rotating a managed service credential, managing leases, and implementing compliance controls.
What You'll Learn
Configure Vault's database secrets engine to manage taskflow_db and hand over the bootstrap password via root rotation
Generate short-lived dynamic credentials and wire one into the running TaskFlow backend, verifying a live database connection
Bring a fixed service account under a Vault static role and confirm rotation invalidates the previous password
Look up, renew, and revoke a credential lease and verify the revoked credential can no longer reach the database
Enable Vault audit logging, confirm database credential access is recorded, enforce TTL limits, and perform bulk lease revocation
