How to Set Up Uptime Kuma with Docker

Step 1: Update Your System

Ensure your system is up-to-date to avoid issues during the installation.

sudo apt update && sudo apt upgrade -y

Step 2: Install Docker

Docker simplifies deploying applications like Uptime Kuma. Follow these steps:

1. Install Docker Dependencies:

sudo apt install -y apt-transport-https ca-certificates curl software-properties-common

1. Add the Docker Repository:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

1. Install Docker:

sudo apt update sudo apt install -y docker-ce

1. Verify Installation:

docker --version

Step 3: Install Docker Compose

Docker Compose makes it easy to manage Uptime Kuma with a simple configuration file.

1. Download Docker Compose:

sudo curl -L "https://github.com/docker/compose/releases/download/2.27.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

1. Make it Executable:

sudo chmod +x /usr/local/bin/docker-compose

1. Verify Installation:

docker-compose --version

Step 4: Set Up Uptime Kuma with Docker Compose

1. Create a directory for Uptime Kuma:

mkdir -p ~/uptime-kuma && cd ~/uptime-kuma

1. Create a docker-compose.yml file:

nano docker-compose.yml

1. Add the following configuration:

version: '3.3'
services:
  uptime-kuma:
    image: louislam/uptime-kuma:latest
    container_name: uptime-kuma
    restart: unless-stopped
    ports:
      - "3001:3001"
    volumes:
      - ./data:/app/data

1. Save the file and exit.
2. Start Uptime Kuma:

docker-compose up -d

Step 5: Access the Uptime Kuma Dashboard

Once the Docker container is running, open your browser and visit:

http://<your-server-ip>:3001

Set up your admin account and begin configuring your monitors.

Step 6: Monitor Services and SSL Certificates

1. Add monitors for HTTP, HTTPS, Ping, or TCP services.
2. Configure SSL certificate checks to get alerts before expiration.
3. Customize notification settings for instant updates.

Step 7: Secure Uptime Kuma with SSL (Optional)

For public-facing setups, use a reverse proxy like NGINX or Traefik with Let’s Encrypt for SSL encryption. This ensures secure access to the dashboard.

Step 8: Keep Your Uptime Kuma Setup Updated

Regularly update the Docker container to access the latest features and security fixes:

docker-compose pull
docker-compose up -d
