Pin OpenBao base image from unpinned :2 tag to :2.5.0 (latest stable,
released 2026-02-04) in both the Dockerfile and the dev docker-compose.
CVEs resolved:
- CVE-2025-68121 (CRITICAL): Go stdlib crypto/tls session resumption
- CVE-2024-8185 (HIGH): DoS via Raft join requests
- CVE-2024-9180 (HIGH): Root namespace privilege escalation
- CVE-2025-59043 (HIGH): DoS via malicious JSON
- CVE-2025-64761 (HIGH): Identity group root escalation
All fixed in OpenBao >= 2.4.4; v2.5.0 includes all patches plus new
features (horizontal read scalability, OCI plugin distribution).
Files changed:
- docker/openbao/Dockerfile: FROM tag 2 -> 2.5.0
- docker/docker-compose.yml: openbao + openbao-init image tags 2 -> 2.5.0
The production/swarm compose files use the custom-built
git.mosaicstack.dev/mosaic/stack-openbao image which is built FROM
this Dockerfile, so they inherit the fix on next CI build.
Fixes#363
The docker-build-openbao pipeline step was failing because the Dockerfile
was missing from docker/openbao/.
Created a minimal Dockerfile that:
- Uses official quay.io/openbao/openbao:2 as base
- Copies config.hcl and init.sh into the image
- Exposes port 8200
- Preserves the default entrypoint from base image
This allows Kaniko to build the stack-openbao image for Swarm deployment.
Fixes pipeline #325 docker-build-openbao failure.

Implements secure credential storage using OpenBao Transit encryption.
Features:
- Auto-initialization on first run (1-of-1 Shamir key for dev)
- Auto-unseal on container restart with verification and retry logic
- Transit secrets engine with 4 named encryption keys
- AppRole authentication with Transit-only policy
- Localhost-only API binding for security
- Comprehensive integration test suite (22 tests, all passing)
Security:
- API bound to 127.0.0.1 (localhost only, no external access)
- Unseal verification with 3-attempt retry logic
- Sanitized error messages in tests (no secret leakage)
- Volume-based secret reading (doesn't require running container)
Files:
- docker/openbao/config.hcl: Server configuration
- docker/openbao/init.sh: Auto-init/unseal script
- docker/docker-compose.yml: OpenBao and init services
- tests/integration/openbao.test.ts: Full test coverage
- .env.example: OpenBao configuration variables
Closes#357
