Flask deployment questions
What does the Flask template deploy?
Use the Flask template in Server Compass to deploy a generated Flask starter on your VPS, then verify the app loads in a browser.
Which port did the tutorial use?
The tutorial used host port 5000, mapped to container port 5000.
Should this become a blog post?
No. The deployment guide should live on the Flask template detail page and be linked from the reusable template deployment docs page.
Command Line Setup
Install Flask Manually
Set up Flask yourself using Docker Compose and the command line.
1
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-ipFirst time? Make sure Docker is installed on your VPS. Run: curl -fsSL https://get.docker.com | sh
2
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/flask3
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
Configuration Options
PORTApplication port(default: 5000)FLASK_APPFlask app entry point(default: app.py)WSGI_MODULEGunicorn WSGI module(default: app:app)SECRET_KEYFlask secret keyDATABASE_URLDatabase URL4
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
docker compose logs -f5
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:5000Skip the Terminal
