Databases Overview
Miabi can provision and run managed databases as Docker containers, owned by a workspace and ready for your apps to consume — no manual container wrangling required.
Supported engines
| Engine | Typical use |
|---|---|
| PostgreSQL | General-purpose relational database. |
| MySQL | Relational database, broad app compatibility. |
| MariaDB | MySQL-compatible relational database. |
| Redis | In-memory cache, queues, sessions. |
| MongoDB | Document database. |
| libSQL | SQLite-compatible edge/embedded database (Turso sqld), accessed over HTTP. |
libSQL behaves a little differently from the other engines: an instance hosts a
single database (you can't create additional logical databases on it), clients speak
HTTP/Hrana rather than a wire protocol (so there's no psql-style shell), and it
authenticates with a JWT auth token instead of a username/password. See
Access & Credentials.
What "managed" means
When you provision a database, Miabi:
- Runs the engine in a container scoped to your workspace.
- Generates and stores managed credentials, encrypted at rest.
- Connects it to the workspace's internal network so apps can reach it — without exposing any port on the host.
- Tracks its engine, version, and resource sizing so you can upgrade or scale later.
You don't get root over the host's Docker; you get a database that Miabi keeps wired up to the rest of your workspace.
Lifecycle
- Provision — pick an engine, version, and size. See Provisioning.
- Connect — apps consume the credentials over the internal network.
- Operate — monitor, back up, and upgrade over time.
- Decommission — delete when no longer needed (take a backup first).
Where related features live
- Access from your machine — databases aren't exposed to the host by default; use port forwarding for temporary external access.
- Backups — scheduled and manual backups are covered in Storage & Backups.
- Upgrades — in-place engine version upgrades.
Redis backups are not yet supported. Treat Redis as a cache/queue you can rebuild, not as your source of truth, until backup support lands.
