Updates

Keep your Bloqd installation up to date with the latest features and security fixes.

Update Strategy

Version Numbering

Bloqd follows semantic versioning (SemVer):

Version	Meaning	Example
Major	Breaking changes	1.x.x → 2.0.0
Minor	New features, backwards compatible	1.0.x → 1.1.0
Patch	Bug fixes, security patches	1.0.0 → 1.0.1

Update Channels

Channel	Tag	Stability
Stable	latest	Production ready
Beta	beta	Feature preview
Development	dev	Unstable, testing only

Updating the Server

Docker (Recommended)

# Navigate to Bloqd directory
cd /opt/bloqd

# Pull latest image
docker compose pull

# Restart with new image
docker compose up -d

# Verify version
docker compose exec bloqd node -e "console.log(require('./package.json').version)"

Zero-Downtime Update

# Pull new image without stopping
docker compose pull

# Recreate container with new image
docker compose up -d --no-deps bloqd

# Watch logs for startup
docker compose logs -f bloqd

Rollback

# Stop current container
docker compose down

# Use specific version
# Edit docker-compose.yml or use command line
docker compose pull bloqd/bloqd-server:1.0.0

# Start with previous version
docker compose up -d

Updating Agents

Automatic Updates

Agents can be updated remotely from the dashboard:

1. Navigate to Servers → Select server → Agent tab
2. Click Update Agent
3. Confirm the update

Manual Agent Update

On each managed server:

# Download latest installer
curl -sSL https://your-bloqd-server.com/api/v1/install -o /tmp/install.sh

# Run with update flag
sudo bash /tmp/install.sh --update

Bulk Agent Update

From the dashboard:

1. Navigate to Servers
2. Select multiple servers (checkbox)
3. Click Bulk Actions → Update Agents
4. Monitor progress in the command queue

Agent Update via API

# Update single agent
curl -X POST "https://bloqd.example.com/api/v1/servers/{server_id}/agent/update" \
  -H "Authorization: Bearer f2b_your_api_key"

# Update all agents
curl -X POST "https://bloqd.example.com/api/v1/servers/agents/update-all" \
  -H "Authorization: Bearer f2b_your_api_key"

Pre-Update Checklist

Before Updating Server

• Backup database - See Backup & Restore
• Check changelog - Review breaking changes
• Test in staging - If possible, test update first
• Plan maintenance window - Notify users if needed
• Verify disk space - Ensure space for new images

Before Updating Agents

• Check agent compatibility - Server and agent versions must be compatible
• Update server first - Always update server before agents
• Test on one server - Update a single agent first
• Have SSH access ready - In case of issues

Database Migrations

Database migrations run automatically on startup:

# View migration logs
docker compose logs bloqd | grep -i migration

# Example output
# [INFO] Running migrations...
# [INFO] Migration 001_initial: already applied
# [INFO] Migration 002_add_commands: already applied
# [INFO] Migration 003_add_siem: applying...
# [INFO] Migration 003_add_siem: completed
# [INFO] All migrations complete

Manual Migration

If automatic migration fails:

# Enter container
docker compose exec bloqd sh

# Run migrations manually
npm run migrate

# Check migration status
npm run migrate:status

Troubleshooting Updates

Server Won't Start After Update

# Check logs
docker compose logs bloqd

# Common issues:
# 1. Database migration failed
# 2. Missing environment variable
# 3. Port already in use

Fix migration issues:

# Restore database backup
cp ./backups/bloqd-backup.db ./data/bloqd.db

# Try update again
docker compose up -d

Agent Update Failed

# Check agent logs
journalctl -u bloqd-agent -n 100

# Reinstall agent
curl -sSL https://your-bloqd-server.com/api/v1/install | sudo bash

Version Mismatch

If agent and server versions are incompatible:

# Check versions
# Server
docker compose exec bloqd node -e "console.log(require('./package.json').version)"

# Agent
cat /etc/bloqd/agent.yaml | grep version

Resolution: Always update server first, then agents.
