OpenBao in Practice: Operating an Open Vault-Style Secrets Platform

"OpenBao in Practice: Operating an Open Vault‑Style Secrets Platform"

OpenBao is not “just a secrets store”—it’s a security control plane whose smallest misconfiguration can become an organization-wide incident. This book is written for experienced operators, SREs, platform engineers, and security engineers who need a precise mental model of how OpenBao behaves under pressure: failures, upgrades, compromised workloads, and human error. If you run production infrastructure and want to make secrets delivery boring, predictable, and auditable, this is your playbook.

You’ll learn OpenBao end-to-end as a single pipeline—auth to policy evaluation to secrets engine to audit—and use that model to design trust boundaries and rank operational risks. The book goes deep on secure bootstrap, storage durability and HA semantics, sealing and unsealing as a real security boundary, and least-privilege at scale through tokens, leases, and policy composition. It then tackles identity integrations (Kubernetes, OIDC/JWT), production operations of KV, dynamic credentials, PKI, and Transit, and finishes with automation patterns, audit-driven forensics, disciplined upgrades, disaster recovery engineering, namespaces/multi-tenancy, and migration from Vault CE.

Expect CLI/API-first workflows, runbook-grade procedures, and decision criteria grounded in threat modeling and failure modes. Familiarity with TLS, Linux operations, Kubernetes, and IAM concepts is assumed.
