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:
