🚀 How to Self-Host These Apps on Ubuntu Server (Step-by-Step)

We’ll walk through installing AppFlowy as an example! 🎯

🔧 Step 1: Prepare Your Server

sudo apt update && sudo apt upgrade -y
sudo apt install docker.io docker-compose -y

Make sure Docker is running:

sudo systemctl enable --now docker

📂 Step 2: Create a Docker Compose File for AppFlowy

Create a directory for your app:

mkdir ~/appflowy && cd ~/appflowy
nano docker-compose.yml

Paste this Docker Compose config:

version: '3.8'
services:
  appflowy:
    image: appflowy/appflowy:latest
    ports:
      - '8080:80'
    volumes:
      - appflowy_data:/appflowy/data
    restart: unless-stopped
volumes:
  appflowy_data:

🚀 Step 3: Start the Container

Save the file, then run:

docker-compose up -d

Your AppFlowy instance should be live at:

http://your-server-ip:8080

🔒 Step 4: Secure with Nginx & SSL

(Optional but recommended!) Use Nginx as a reverse proxy and add a free SSL certificate with Let’s Encrypt.

Would you like me to add this Nginx setup, or cover another app installation? Let me know! ✌️
