About this template

Overview

Design database diagrams and generate SQL with drawDB on Sealos. Open the browser editor over HTTPS, then export your work from its local browser storage.

From the documentation

drawDB runs as a single web service served by NGINX. Users open the editor, choose a database dialect, build ER diagrams, import SQL, export diagrams, and generate SQL without creating an account.

How to deploy drawDB

  1. Choose Deploy now to start drawDB in your Sealos workspace.
  2. Sign in to Sealos and review the template configuration in your workspace.
  3. Launch the template, then inspect the application status and resource cards in Canvas.

Resources to plan for

Start with the resources defined by the drawDB template. Review CPU, memory, persistent storage, and network allocations for every service in Canvas. Capacity needs depend on your data and workload; monitor usage as they grow.

Template configuration and setup

Access after deployment

Use the application URL or connection details shown in Canvas. Follow the deployment guide for first-time account setup or client configuration, and keep generated credentials available for that step.

Hosting and billing

Sealos monthly plans include compute, memory, storage, and traffic. Size your plan for all deployed services. Software licenses and external AI or API services may have separate terms and charges. Confirm the applicable plan and optional charges in Cost Center.

Deploy and Host drawDB on Sealos

drawDB is a browser-based database entity relationship diagram editor and SQL generator. This template deploys the drawDB static web app on Sealos Cloud with automatic HTTPS access.

About Hosting drawDB

drawDB runs as a single web service served by NGINX. Users open the editor, choose a database dialect, build ER diagrams, import SQL, export diagrams, and generate SQL without creating an account.

The template deploys the core drawDB editor. Diagram data is stored in the browser through drawDB's client-side storage and can be exported or imported by users when they need portable files.

drawDB also offers an optional sharing backend through drawdb-server. That backend requires external email and GitHub token configuration, so this template keeps the default account-free editor flow.

Common Use Cases

  • Database schema design: Create ER diagrams for new database projects.
  • SQL review: Import SQL scripts and inspect table relationships visually.
  • Migration planning: Generate SQL and compare schema changes before implementation.
  • Team documentation: Export diagrams as files or images for architecture notes.
  • Learning databases: Explore MySQL, PostgreSQL, SQLite, MariaDB, MSSQL, Oracle SQL, and generic schema models.

Dependencies for drawDB Hosting

The Sealos template includes the drawDB web container, a Kubernetes Deployment, Service, Ingress, App link, and a small NGINX configuration that opens the editor route directly.

Deployment Dependencies

Implementation Details

Architecture Components:

This template deploys one service:

  • drawDB Web App: Static React application served by NGINX on port 80.

Configuration:

  • The App link opens /editor so users land on the working editor.
  • The NGINX configuration redirects / to /editor.
  • The deployment uses the official ghcr.io/drawdb-io/drawdb:v1.5.0 container image.
  • Resource requests and limits follow the docker-to-sealos baseline for lightweight web services.
  • No database, persistent volume, or object storage is required for the default editor flow.

License Information:

drawDB is licensed under the AGPL-3.0 license. This Sealos template follows the same application distribution terms.

Why Deploy drawDB on Sealos?

Sealos is an AI-assisted Cloud Operating System built on Kubernetes that unifies the application lifecycle from deployment to operations. By deploying drawDB on Sealos, you get:

  • One-Click Deployment: Deploy drawDB from the App Store template page without writing Kubernetes YAML.
  • Automatic HTTPS: Every deployment receives a public URL with managed TLS.
  • Simple Operations: Use Canvas, the AI dialog, and resource cards for post-deployment changes.
  • Pay-as-You-Go Efficiency: Run a lightweight editor with small baseline resources.
  • Kubernetes Foundation: Keep the portability and resilience of Kubernetes while using a simpler interface.

Deployment Guide

  1. Open the drawDB template and click Deploy Now.
  2. Configure the app name and public host in the popup dialog.
  3. Wait for deployment to complete, usually 2-3 minutes. After deployment, you will be redirected to the Canvas. For later changes, describe your requirements in the AI dialog, or click the relevant resource cards to modify settings.
  4. Access drawDB from the App link. The app opens the /editor route.
  5. Choose a database dialect such as MySQL or PostgreSQL, then start adding tables and relationships.

Configuration

The default deployment works without setup steps. To enable sharing features, deploy drawdb-server separately, configure its email and GitHub token settings, and provide its URL to the drawDB frontend through VITE_BACKEND_URL in a custom build.

Scaling

drawDB is a static editor and usually runs well as a single replica. To adjust resources:

  1. Open the Canvas for your deployment.
  2. Click the drawDB Deployment resource card.
  3. Adjust CPU, memory, or replica count.
  4. Apply the change in the dialog.

Troubleshooting

The editor opens with an empty diagram

Choose a database dialect from the startup dialog, then add tables from the editor toolbar.

Sharing options need server configuration

Use the optional drawdb-server project and connect a custom frontend build to that backend.

From launch to everyday operations

Why deploy
on Sealos

A shorter path from an app you want to an app you can run. Sealos brings deployment and ongoing operations into one place.

  1. One-click deployment

    Start with a ready-made template. Review its configuration and launch from the Sealos console.

  2. Managed Kubernetes

    Run on managed infrastructure with built-in workload scheduling and recovery.

  3. Automatic HTTPS

    Give your application a public HTTPS endpoint with certificates managed for you.

  4. Persistent storage

    Keep application data on persistent volumes across container restarts.

  5. Room to grow

    Adjust CPU, memory, and replicas from the console as your workload changes.

One template. Connected resources.

You Get the Whole Stack

Sealos provisions the resources defined by your template and brings them together in your workspace.

  • App Service

    Container workloads with configurable CPU, memory, and replicas.

  • Public HTTPS URL

    An address for your app, with managed TLS certificates.

  • Database

    A database provisioned alongside your app when the template calls for one.

  • Persistent Volume

    Storage for the files and data your application needs to keep.

  • Environment Variables

    Application settings and secrets configured in one place.

  • Logs & Metrics

    Inspect container logs and resource usage from the console.

Resources and their configuration vary by template. Review the deployment form for this app’s exact setup.
