Relational Databases
A relational database cluster is a managed MySQL or PostgreSQL deployment on your Hetzner account. myStack provisions servers, DNS endpoints, security groups, backups, and parameter groups.
Engines
| Engine | Version | Port | Admin user |
|---|---|---|---|
| MySQL | 5.7 | 3306 | root |
| PostgreSQL | 16 | 5432 | postgres |
In the console
Open Databases in the navigation pane. From there you can:
- List and create clusters for MySQL or PostgreSQL
- Manage parameter groups, backup policies, backup runs, replications, and migrations
What myStack creates
When you create a cluster, myStack:
- Provisions the primary server
- Creates read/write and read-only DNS endpoints
- Attaches a managed security group, backup storage, a dedicated data key for backup encryption, and default parameter group
- Attaches the account default TLS certificate if one exists
- Sets status to provisioning until the cluster is Ready
Note
While status is restricted (for example, pending), the console disables modification actions. For MongoDB, see Document Databases. For Redis or Valkey, see Caches.
