Command Line Setup

Install Flask Manually

Set up Flask yourself using Docker Compose and the command line.

Access Your VPS Terminal

Use your terminal to securely access your server. You'll need your server's IP address.

terminal

# Connect via SSH
ssh root@your-vps-ip

# Alternative with key file
ssh -i /path/to/key root@your-vps-ip

First time? Make sure Docker is installed on your VPS. Run: curl -fsSL https://get.docker.com | sh

Set Up the Deployment Folder

Initialize a project folder on your server.

terminal

# Create and navigate to project directory
mkdir -p ~/apps/flask
cd ~/apps/flask

Set Up the Stack Definition

Use this Docker Compose configuration for your deployment:

docker-compose.yml

services:
  flask:
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - "5000:5000"
    environment:
      - FLASK_APP=app.py
      - FLASK_ENV=production
      - WSGI_MODULE=app:app
      - SECRET_KEY=<your-secret-key>
      - DATABASE_URL=<your-database-url>
    restart: unless-stopped

Start the Containers

Bring up your containers in detached mode.

terminal

# Start all services
docker compose up -d

# List running containers
docker compose ps

# Watch the logs

Set Up Firewall Rules

Allow the application port through your server's firewall.

terminal

# Allow the application port through firewall
sudo ufw allow 5000/tcp
sudo ufw reload

# Access your app at:
# http://your-server-ip:5000

Flask FAQ

Common questions about self-hosting Flask

How do I deploy Flask with Server Compass?

Simply download Server Compass, connect to your VPS, and select Flask from the templates list. Fill in the required configuration and click Deploy. The entire process takes under 3 minutes.

What are the system requirements for Flask?

Flask requires a minimum of 256MB RAM. We recommend a VPS with at least 1024MB RAM for optimal performance. Any modern Linux server with Docker support will work.

Can I migrate my existing Flask data?

Yes! Server Compass provides volume mapping that allows you to import existing data. You can also use standard Flask backup and restore procedures.

How do I update Flask to the latest version?

Server Compass makes updates easy. Simply click the Update button in your deployment dashboard, and the latest Flask image will be pulled and deployed with zero downtime.

Is Flask free to self-host?

Flask is open-source software. You only pay for your VPS hosting (typically $5-20/month) and optionally Server Compass ($29 one-time). No subscription fees or per-seat pricing.
