Step-by-Step Installation

1. Connect to Your Server

Log in to your Ubuntu 24.04 server via SSH:

 
ssh root@your-server-ip

2. Update and Install Prerequisites

Update system packages:

 
apt update && apt upgrade -y

Install required dependencies:

 
apt install -y apt-transport-https ca-certificates curl gnupg lsb-release python3-pip

3. Install Docker

Install Docker from Ubuntu’s repositories:

 
apt install -y docker.io systemctl enable --now docker

Verify the installation:

 
docker --version

4. Prepare Persistent Directories

Create directories for cache and configuration to ensure data survives container restarts:

 
mkdir -p /var/cache/ntfy mkdir -p /etc/ntfy chmod 755 /var/cache/ntfy /etc/ntfy

5. Pull and Run the Ntfy Container

Download the official Ntfy image:

 
docker pull binwiederhier/ntfy

Run the container:

 
docker run -d \ --name ntfy \ -p 80:80 \ -v /var/cache/ntfy:/var/cache/ntfy \ -v /etc/ntfy:/etc/ntfy \ -e TZ=UTC \ --restart unless-stopped \ binwiederhier/ntfy serve

Explanation of key parameters

  • -p 80:80 exposes the Ntfy web interface and API on port 80.

  • -v /var/cache/ntfy stores the persistent message cache.

  • -v /etc/ntfy stores configuration files.

  • --restart unless-stopped ensures Ntfy restarts automatically after a reboot.

6. Access the Web Interface

Open a browser and visit:

 
http://<your-server-ip>

The Ntfy dashboard will appear, ready for you to create topics and send messages.
