About this template

Overview

Start a web application with the Full Stack FastAPI template on Sealos, combining a Python API, PostgreSQL database, and React frontend.

How to deploy Full Stack FastAPI

Choose Deploy now to start Full Stack FastAPI in your Sealos workspace.
Review SECRET_KEY, FIRST_SUPERUSER, FIRST_SUPERUSER_PASSWORD and the remaining settings in the deployment form.
Launch the template, then inspect the application status and resource cards in Canvas.

Resources to plan for

Start with the resources defined by the Full Stack FastAPI 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.

Full Stack FastAPI

Overview

Production-ready FastAPI + PostgreSQL + Frontend stack

This Sealos template deploys Full Stack FastAPI as the full-stack-fastapi application. It uses the repository-maintained Sealos manifest and keeps deployment, networking, and storage configuration inside the template.

Deploy on Sealos

Open this template in the Sealos App Store, review the configuration values, and click Deploy. Sealos renders the template variables, creates the required Kubernetes resources, and manages the public endpoint for the application.

Access

After deployment, open https://${{ defaults.app_host }}.${{ SEALOS_CLOUD_DOMAIN }}. The concrete hostname is generated from defaults.app_host and your Sealos Cloud domain.

Configuration

The following user-facing inputs are available during deployment:

Name	Description	Required	Default
`EMAILS_FROM_EMAIL`	Sender email for SMTP (optional)	`false`	``
`FIRST_SUPERUSER`	Initial superuser email for backend	`true`	``
`FIRST_SUPERUSER_PASSWORD`	Initial superuser password for backend	`true`	`<redacted>`
`SECRET_KEY`	Backend secret key (JWT signing)	`true`	`<redacted>`
`SENTRY_DSN`	Sentry DSN (optional)	`false`	``
`SMTP_HOST`	SMTP host (optional)	`false`	``
`SMTP_PASSWORD`	SMTP password (optional)	`false`	`<redacted>`
`SMTP_USER`	SMTP user (optional)	`false`	``

Keep sensitive values in Sealos-managed inputs or generated defaults. Do not commit private credentials to the template repository.
