Create your first database

In dFlow, a managed database runs as a database Service inside an Application (not as a separate “addon” outside the model).

Read Databases overview under Databases in the sidebar and Database services under Services in the sidebar for how this maps to the UI.

Prerequisites

• An Application with compute attached so the Environment can schedule the database Service.

• You know which engine you need (PostgreSQL, MySQL, MongoDB, Redis, etc.).

• Optional: Service settings under Services in the sidebar if you plan to wire connection strings into app Services.

1. Add a database Service

1. Open your Application and the Environment where the database should run.

2. Create Service (or Add new on an empty canvas) and choose a database type.

3. Set name, version (if offered), storage, and credentials as the UI prompts.

2. Deploy

1. Save the Service configuration.

2. Click Deploy or Redeploy so the database is provisioned on the Worker Node.

Expected outcome: The database Service shows a successful Deployment and a healthy status in the UI.

3. Get credentials and connect

1. Open the Service detail page and find connection details or environment variables dFlow generated.

2. Reference those values from app Services using the patterns in Service settings under Services in the sidebar.

3. For external tools, see Database credentials and connections under Databases in the sidebar when published.
