Quick start

Create your first Flask app:

sudo fmanager create app1 --domain app1.com

Create systemd service:

sudo fmanager gen-systemd app1
sudo systemctl daemon-reload
sudo systemctl enable --now app1

Create Nginx config:

sudo fmanager gen-nginx app1
sudo nginx -t
sudo systemctl reload nginx

Add SSL:

sudo fmanager ssl app1 --email you@example.com --redirect

Existing Flask app

If you already have an app:

sudo fmanager add app1 \
  --path /apps/app1 \
  --domain app1.com \
  --port 8001 \
  --module app:app

Then generate systemd + Nginx:

sudo fmanager gen-systemd app1
sudo systemctl daemon-reload
sudo systemctl enable --now app1

sudo fmanager gen-nginx app1
sudo nginx -t
sudo systemctl reload nginx
