Deploy Guides

Learn how to host your application on Vertra Cloud with language and framework-specific guides. Each tutorial covers project structure, necessary configuration and the complete deployment process.

Node.js

Node.js applications with or without framework.

Python

Python scripts, bots and APIs.

Express.js

REST APIs with Express.js.

Fastify

High-performance APIs with Fastify.

Next.js

React applications with SSR and SSG.

Go

APIs and services in Go.

Static Sites

HTML, CSS and pure JavaScript.

Discord Bots

Bots for Discord with discord.js or discord.py.

Common Structure

Regardless of the framework chosen, every deployment on Vertra Cloud follows the same structure:

Prepare the project

Organize files and configure the main file and startup command.

Configure (optional)

Create the vertracloud.config file with desired settings.

Upload

Send the code via ZIP, GitHub or VSCode extension.

Verify

Monitor logs and application status in the dashboard.

`vertracloud.config` File

The configuration file is optional but recommended. It must be at the project root:

MAIN=index.js
START=npm start
SUBDOMAIN=my-app
VERSION=recommended
MEMORY=512
AUTORESTART=true

Field	Description	Required
`MAIN`	Application’s main file	Yes
`START`	Custom startup command	No
`SUBDOMAIN`	Custom subdomain	No
`VERSION`	Runtime version (`recommended`, `latest`)	No
`MEMORY`	Memory in MB	No
`AUTORESTART`	Auto-restart on crash	No

Application Port

Web applications must listen on the port defined by the PORT environment variable. The platform automatically injects this variable into the container.

Node.js
Python
Go

const port = process.env.PORT || 80;
app.listen(port, '0.0.0.0', () => {
  console.log(`Server running on port ${port}`);
});

import os
port = int(os.environ.get('PORT', 80))
app.run(host='0.0.0.0', port=port)

port := os.Getenv("PORT")
if port == "" {
    port = "80"
}
http.ListenAndServe("0.0.0.0:"+port, nil)

Always use 0.0.0.0 as host instead of localhost or 127.0.0.1. Inside the container, binding must be on all interfaces for external traffic to reach the application.
