Question 1

What is OpenBao?

Accepted Answer

OpenBao is a secrets management platform — a central, audited place to store database passwords, API keys, certificates, and encryption keys, with policies controlling who can read what. It can also generate short-lived dynamic credentials on demand.

Question 2

Why OpenBao instead of HashiCorp Vault?

Accepted Answer

Licensing. HashiCorp moved Vault to the Business Source License, which is not open source and imposes conditions many organizations can't accept.

Question 3

What does dev mode mean here — and why does it matter?

Accepted Answer

It matters a great deal. This deployment runs with the -dev flag: storage is entirely in memory, the vault auto-unseals so no unseal keys are ever generated, and TLS is disabled. Every secret, policy, and mount disappears when the container restarts.

Question 4

Where are the unseal keys?

Accepted Answer

There aren't any, because dev mode auto-unseals. In a production OpenBao or Vault deployment, initialization produces unseal keys that must be safeguarded and supplied to unseal the vault after a restart — a central part of the security model. Dev mode skips that entirely for convenience.

Question 5

Which port does it use and how do I log in?

Accepted Answer

The web UI and API are on host port 8245, mapped from the container's standard 8200 — so point clients and the CLI at 8245, not 8200. Authentication uses the 24-character root token the installer generates and prints.
