Deployment Aplikasi Flask di Ubuntu 24.04, dari awal sampai bisa diakses via browser pakai domain atau IP publik. Kita akan deploy menggunakan Gunicorn + Nginx supaya production-ready.

Install Dependensi Dasar

sudo apt update && sudo apt upgrade -y
sudo apt install python3 python3-pip python3-venv nginx -y

Siapkan Direktori Project

mkdir ~/flaskapp
cd ~/flaskapp
python3 -m venv venv
source venv/bin/activate

Install Flask dan Gunicorn

pip install flask gunicorn

Buat Aplikasi Flask (`app.py`)

# app.py

from flask import Flask 

app = Flask(__name__)

@app.route('/')
def home():
    return "Hello, Metro TV from Flask on Ubuntu 24.04!"

Test Jalankan Lokal

python app.py

Tambahkan ini kalau kamu mau bisa akses langsung: 

if __name__ == '__main__':
    app.run(host='0.0.0.0')

Jalankan dengan Gunicorn

gunicorn --bind 0.0.0.0:8000 app:app

Cek dengan: `http://YOUR_SERVER_IP:8000`

(Opsional) Buat File Service Systemd

sudo nano /etc/systemd/system/flaskapp.service

Isi dengan: 

[Unit]
Description=Gunicorn instance to serve flaskapp
After=network.target 

[Service]
User=ubuntu
Group=www-data
WorkingDirectory=/home/ubuntu/flaskapp
Environment="PATH=/home/ubuntu/flaskapp/venv/bin"
ExecStart=/home/ubuntu/flaskapp/venv/bin/gunicorn --workers 3 --bind unix:flaskapp.sock -m 007 app:app

[Install]
WantedBy=multi-user.target

> Ganti `ubuntu` sesuai user kamu, dan `WorkingDirectory` sesuai folder.

Lalu: 

sudo systemctl daemon-reexec
sudo systemctl daemon-reload
sudo systemctl start flaskapp
sudo systemctl enable flaskapp

Konfigurasi Nginx

sudo nano /etc/nginx/sites-available/flaskapp

Isi dengan: 

nginx
server {
    listen 80;
    server_name your_domain.com;  # Atau IP kamu

    location / {
        include proxy_params;
        proxy_pass http://unix:/home/ubuntu/flaskapp/flaskapp.sock;
    }
}

Aktifkan config-nya: 

sudo ln -s /etc/nginx/sites-available/flaskapp /etc/nginx/sites-enabled
sudo nginx -t
sudo systemctl restart nginx

(Opsional) Tambah HTTPS dengan Let's Encrypt

Install Certbot: 

sudo apt install certbot python3-certbot-nginx -y

Dapatkan SSL gratis: 

sudo certbot --nginx -d your_domain.com

Final Cek

Bonus: Struktur Folder
