Getting Started

Deploying Uptime Kuma with Docker Compose only requires a few steps.

Step 1: Create a Docker Compose File

Create a docker-compose.yml file in your project directory.

docker-compose.yaml

version: '3.8'


services:
  uptime-kuma:
    image: louislam/uptime-kuma:latest
    container_name: uptime-kuma
    restart: always
    volumes:
      - ./uptime-kuma-data:/app/data
    ports:
      - 3000:3000

Step 2: Start the Container

Launch the service using Docker Compose.

Run: docker-compose up -d

Docker automatically downloads the latest image and starts the monitoring service.

Step 3: Access the Dashboard

Once the container is running, open:

http://localhost:3001

Complete the initial administrator account setup.

Step 4: Create Your First Monitor

Click Add New Monitor and configure:

Save the monitor to begin tracking uptime immediately.
