**Important Notes:**
- **OpenBao Requirement:** OpenBao MUST be deployed as standalone container (not in swarm). Use `docker-compose.openbao.yml` or external Vault.
- Swarm does NOT support docker-compose profiles
- To use external services (PostgreSQL, Authentik, etc.), manually comment them out in `docker-compose.swarm.yml`
- OpenBao requires manual initialization (no auto-init sidecar in swarm mode)

# OpenBao Deployment Guide
## Overview
OpenBao provides Transit encryption for sensitive credentials in Mosaic Stack. Due to the stateful nature of secrets management and port binding requirements, OpenBao has specific deployment constraints.
## Deployment Options
### Option 1: Standalone Container (Recommended for Swarm)
**When to use:**
- Docker Swarm deployments
- You want OpenBao isolated from the main stack
- You need guaranteed port availability
**How to deploy:**
```bash
# Deploy OpenBao as standalone container
docker compose -f docker-compose.openbao.yml up -d
# Check status
docker ps | grep openbao
# View logs
docker logs mosaic-openbao
docker logs mosaic-openbao-init
# The init container auto-initializes OpenBao on first run
# Check initialization status
docker logs mosaic-openbao-init
```
**Configuration:**
The standalone deployment:
- Binds to `127.0.0.1:8200` (localhost only for security)
- Auto-initializes via `openbao-init` sidecar
- Connects to swarm stack via `mosaic_internal` network
- Uses named volumes for persistence
**File:** `docker-compose.openbao.yml`
### Option 2: Bundled (Standalone Docker Compose Only)
**When to use:**
- Standalone docker-compose deployment (NOT swarm)
- Development/testing environments
- All-in-one turnkey setup
**How to deploy:**
```bash
# Use docker-compose.yml with full profile
export COMPOSE_PROFILES=full
docker compose up -d
```
**Configuration:**
OpenBao runs as part of the main stack with:
- `openbao` and `openbao-init` services
- Automatic initialization on first startup
- Integrated with other services
**File:** `docker-compose.yml` (with `COMPOSE_PROFILES=full` or `COMPOSE_PROFILES=openbao`)
### Option 3: External HashiCorp Vault
**When to use:**
- Production environments with existing Vault infrastructure
- Managed secrets service (HashiCorp Cloud Platform, AWS Secrets Manager + Vault)
- Multi-region deployments
- High availability requirements
**How to configure:**
1. Set environment variables:
```bash
OPENBAO_ADDR=https://vault.example.com:8200
OPENBAO_ROLE_ID=your-approle-role-id
OPENBAO_SECRET_ID=your-approle-secret-id
```
2. Ensure external Vault has:
- Transit secrets engine enabled
- Encryption key created: `mosaic-credentials`
- AppRole configured for Mosaic API authentication
3. Comment out OpenBao in all compose files
4. API will automatically connect to external Vault
### Option 4: Fallback Mode (No Vault)
**When to use:**
- Development/testing without secrets infrastructure
- Simplified deployments
- Gradual migration to Vault
**How to configure:**
1. Comment out or don't deploy OpenBao
2. Set `ENCRYPTION_KEY` in `.env` (required!)
3. API automatically falls back to AES-256-GCM encryption
**Configuration:**
```bash
# Generate encryption key
ENCRYPTION_KEY=$(openssl rand -hex 32)
echo "ENCRYPTION_KEY=$ENCRYPTION_KEY" >> .env
```
**Note:** This provides graceful degradation but lacks the key management features of OpenBao/Vault.
## Why OpenBao Can't Run in Swarm
OpenBao is a **stateful service** that binds to a specific port (`8200`). In Docker Swarm:
1. **Port binding conflicts:** Swarm services use overlay networks and can't reliably bind to host ports
2. **State management:** OpenBao maintains unsealed state and encryption keys that don't work with Swarm's task model
3. **Multiple replicas:** Swarm tries to create multiple replicas, causing port conflicts
**Solution:** Deploy OpenBao as a standalone container that connects to the swarm network.
## Deployment Workflows
### Swarm + Standalone OpenBao
```bash
# 1. Deploy OpenBao standalone
docker compose -f docker-compose.openbao.yml up -d
# 2. Wait for initialization
sleep 30
docker logs mosaic-openbao-init
# 3. Deploy swarm stack
IMAGE_TAG=dev ./scripts/deploy-swarm.sh mosaic
# 4. Verify API connects to OpenBao
docker service logs mosaic_api | grep -i openbao
```
### Standalone Compose + Bundled OpenBao
```bash
# 1. Set profile
export COMPOSE_PROFILES=full
# 2. Deploy everything
docker compose up -d
# 3. Verify OpenBao initialization
docker logs mosaic-openbao-init
```
### External Vault
```bash
# 1. Configure .env with external Vault URL and credentials
# OPENBAO_ADDR=https://vault.example.com:8200
# OPENBAO_ROLE_ID=...
# OPENBAO_SECRET_ID=...
# 2. Deploy stack (no OpenBao)
IMAGE_TAG=dev ./scripts/deploy-swarm.sh mosaic
# 3. Verify API connects to external Vault
docker service logs mosaic_api | grep -i vault
```
## Network Configuration
### Standalone OpenBao with Swarm Stack
The standalone OpenBao container connects to the swarm stack's internal network:
```yaml
networks:
mosaic_internal:
external: true
name: mosaic_internal
```
This allows services in the swarm stack to reach OpenBao at `http://openbao:8200`.
### Port Exposure
- **Standalone:** `127.0.0.1:8200` (localhost only)
- **Bundled:** No port exposure (internal network only)
- **External:** Your Vault URL (typically HTTPS on 8200)
**Security Note:** Never expose OpenBao to the public internet without proper TLS and authentication.
## Initialization and Unsealing
### Auto-Initialization (Standalone & Bundled)
The `openbao-init` sidecar automatically:
1. Initializes OpenBao on first run
2. Creates unseal keys and root token
3. Unseals OpenBao
4. Enables Transit secrets engine
5. Creates `mosaic-credentials` encryption key
6. Sets up AppRole authentication
**Credentials location:** `/openbao/init/approle-credentials` (mounted volume)
### Manual Initialization (External Vault)
For external Vault, you must manually:
```bash
# 1. Enable transit engine
vault secrets enable transit
# 2. Create encryption key
vault write -f transit/keys/mosaic-credentials
# 3. Enable AppRole
vault auth enable approle
# 4. Create role for Mosaic API
vault write auth/approle/role/mosaic-api \
token_policies="default" \
token_ttl=1h \
token_max_ttl=4h
# 5. Get credentials
vault read auth/approle/role/mosaic-api/role-id
vault write -f auth/approle/role/mosaic-api/secret-id
# 6. Set in .env
# OPENBAO_ROLE_ID=<role-id>
# OPENBAO_SECRET_ID=<secret-id>
```
## Troubleshooting
### OpenBao Won't Start in Swarm
**Symptom:** `Error initializing listener: bind: address already in use`
**Cause:** OpenBao cannot run in swarm mode
**Fix:** Deploy as standalone container:
```bash
docker compose -f docker-compose.openbao.yml up -d
```
### API Can't Connect to OpenBao
**Symptom:** API logs show connection errors to OpenBao
**Check:**
1. OpenBao is running: `docker ps | grep openbao`
2. Network connectivity: `docker exec mosaic_api curl http://openbao:8200/v1/sys/health`
3. Environment variable: `OPENBAO_ADDR=http://openbao:8200`
**Swarm specific:** Ensure standalone OpenBao is connected to `mosaic_internal` network
### Initialization Failed
**Symptom:** `openbao-init` container exits with errors
**Check:**
1. OpenBao is healthy: `docker logs mosaic-openbao`
2. Init logs: `docker logs mosaic-openbao-init`
3. Volume permissions: `docker volume inspect mosaic-openbao-init`
**Fix:** Remove volumes and redeploy:
```bash
docker compose -f docker-compose.openbao.yml down -v
docker compose -f docker-compose.openbao.yml up -d
```
### Fallback Mode Active (Unintended)
**Symptom:** API logs show "Using fallback encryption"
**Cause:** OpenBao not reachable
**Fix:**
1. Verify OpenBao deployment
2. Check `OPENBAO_ADDR` in `.env`
3. Test connectivity from API container
## Security Considerations
1. **Never commit unseal keys or root tokens** to version control
2. **Store credentials securely** - Use a password manager or secrets management system
3. **Rotate AppRole secrets regularly** - At least every 90 days
4. **Use TLS for external Vault** - Never use HTTP in production
5. **Restrict port exposure** - OpenBao should only be accessible from API/services
6. **Monitor access logs** - Review Vault audit logs regularly
7. **Backup regularly** - Backup OpenBao volumes and external Vault state

## Deployment
### Deploy the Stack
### Step 1: Deploy OpenBao (Standalone)
**CRITICAL:** OpenBao CANNOT run in swarm mode due to port binding conflicts. Deploy it as a standalone container first.
```bash
cd /opt/mosaic/stack
# Deploy OpenBao standalone
docker compose -f docker-compose.openbao.yml up -d
# Verify OpenBao is running
docker ps | grep openbao
# Check initialization (should complete in ~30 seconds)
docker logs mosaic-openbao-init --follow
# Wait for OpenBao to be ready
sleep 30
```
**Alternative Options:**
- **External Vault:** Skip this step and configure `OPENBAO_ADDR` to point to your external Vault instance
- **Fallback Mode:** Skip this step - API will use AES-256-GCM encryption with `ENCRYPTION_KEY`
See [OpenBao Deployment Guide](OPENBAO-DEPLOYMENT.md) for detailed options.
### Step 2: Deploy the Swarm Stack

## Post-Deployment Configuration
### 1. Initialize OpenBao (CRITICAL)
### 1. Verify OpenBao Initialization
**Important:** Unlike docker-compose, the swarm file does NOT include the `openbao-init` sidecar. You must manually initialize OpenBao:
OpenBao was deployed as a standalone container with automatic initialization. Verify it completed:
```bash
# Wait for OpenBao to be healthy
sleep 30
# Check OpenBao container is running
docker ps | grep openbao
# Get the OpenBao container ID
OPENBAO_CONTAINER=$(docker ps -q -f label=com.docker.swarm.service.name=mosaic_openbao)
# Verify initialization completed
docker logs mosaic-openbao-init
# Initialize OpenBao
docker exec $OPENBAO_CONTAINER bao operator init -key-shares=1 -key-threshold=1
# Expected output:
# ✓ OpenBao initialized successfully
# ✓ Transit engine enabled
# ✓ Encryption key created: mosaic-credentials
# ✓ AppRole authentication configured
# Save the output - you'll need the Unseal Key and Root Token!
# Example output:
# Unseal Key 1: abc123...
# Initial Root Token: xyz789...
# Unseal OpenBao
docker exec $OPENBAO_CONTAINER bao operator unseal <unseal-key-from-above>
# Enable Transit engine
docker exec -e BAO_TOKEN=<root-token> $OPENBAO_CONTAINER \
bao secrets enable transit
# Create encryption key
docker exec -e BAO_TOKEN=<root-token> $OPENBAO_CONTAINER \
bao write -f transit/keys/mosaic-credentials
# Create AppRole for API
docker exec -e BAO_TOKEN=<root-token> $OPENBAO_CONTAINER \
bao auth enable approle
docker exec -e BAO_TOKEN=<root-token> $OPENBAO_CONTAINER \
bao write auth/approle/role/mosaic-api \
token_policies="default" \
token_ttl=1h \
token_max_ttl=4h
# Get Role ID and Secret ID
docker exec -e BAO_TOKEN=<root-token> $OPENBAO_CONTAINER \
bao read auth/approle/role/mosaic-api/role-id
docker exec -e BAO_TOKEN=<root-token> $OPENBAO_CONTAINER \
bao write -f auth/approle/role/mosaic-api/secret-id
# Update API service with AppRole credentials (optional - or store in volume)
docker service update mosaic_api \
--env-add OPENBAO_ROLE_ID=<role-id> \
--env-add OPENBAO_SECRET_ID=<secret-id>
# Test OpenBao connectivity from host
curl http://localhost:8200/v1/sys/health
```
**Automated Alternative:** Create an init script and run it as a Docker container:
```bash
# See docker/openbao/init.sh for reference
# Create a one-time task that runs initialization
docker service create --name openbao-init \
--network mosaic_internal \
--restart-condition=none \
--mount type=volume,source=mosaic_openbao_init,target=/openbao/init \
git.mosaicstack.dev/mosaic/stack-openbao:dev \
/openbao/init.sh
```
**If using external Vault:** Skip this step - verify your external Vault is configured per [OpenBao Deployment Guide](OPENBAO-DEPLOYMENT.md#option-3-external-hashicorp-vault).
### 2. Run Database Migrations
