Managed Databases

Voxeltron provisions and manages database containers alongside your apps — no external services required.

Overview

Every app needs a database. Voxeltron runs fully managed database containers on the same host as your applications, backed by persistent Docker volumes and automatic backups. Connection strings are injected into your app environment automatically — zero configuration required.

Supported Databases

PostgreSQL

The primary relational database. Full SQL support, JSONB columns, extensions, and excellent performance for most workloads.

MySQL

Battle-tested relational database. Wide ecosystem compatibility for apps that require MySQL-specific features or migrations from existing setups.

Redis

In-memory data store for caching, session storage, job queues, and pub/sub messaging. Sub-millisecond latency on the same host.

MongoDB

Document store for flexible schemas and unstructured data. Ideal for content management, event logs, and rapid prototyping.

How It Works

Each database runs as a Docker container with a dedicated persistent volume for data durability. Voxeltron handles the full lifecycle:

Persistent volumes — Data survives container restarts and redeployments.
Automatic backup scheduling — Daily backups run without intervention.
Connection string injection — Credentials are injected as environment variables so your app connects without manual configuration.
Network isolation — Databases are only reachable from your app containers on the internal Docker network.

Provisioning a Database

Create a database from the CLI in one command:

voxeltron db create postgres mydb

Or for other engines:

voxeltron db create mysql mydb
voxeltron db create redis mycache
voxeltron db create mongodb mydocs

You can also provision databases from the TUI Database view — navigate to the Databases panel, select your engine, and give it a name.

Databases are linked to your app automatically. The connection string appears in your app's environment within seconds of provisioning.

Backups

Voxeltron runs automatic daily backups for every managed database. Backups are stored locally by default, with optional upload to any S3-compatible storage for off-site durability.

# Configure S3 backup destination
voxeltron db backup-config mydb \
  --s3-bucket my-backups \
  --s3-region us-east-1

# Trigger a manual backup
voxeltron db backup mydb

# Restore from a specific backup
voxeltron db restore mydb --backup 2026-02-25T03:00:00Z

Point-in-time restore is supported for PostgreSQL and MySQL, allowing you to recover to any moment within the backup retention window.

Connection Strings

When you link a database to an app, Voxeltron automatically injects the connection string as the DATABASE_URL environment variable. Your app reads it at startup — no secrets files or manual wiring needed.

# Example injected variable
DATABASE_URL=postgres://user:pass@voxeltron-db-mydb:5432/mydb

Redis and MongoDB use REDIS_URL and MONGODB_URL respectively, following the same automatic injection pattern.
