Overview
Uptime Kuma is a monitoring tool that can be used to monitor the status of multiple types of services. Install instructions can be found in the uptime kuma documentation.
Installing Docker
These steps are taken directly from Docker’s documentation. I have used these steps on Ubuntu 22.04.3 LTS.
- Remove old/conflicting packages
for pkg in docker.io docker-doc docker-compose docker-compose-v2 podman-docker containerd runc; do sudo apt-get remove $pkg; done- Add Docker’s repository to the machine
sudo apt-get updatesudo apt-get install ca-certificates curl gnupgsudo install -m 0755 -d /etc/apt/keyringscurl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpgsudo chmod a+r /etc/apt/keyrings/docker.gpgecho \ "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \ "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \ sudo tee /etc/apt/sources.list.d/docker.list > /dev/nullsudo apt-get update- Install docker packages

sudo docker run hello-worldUptime Kuma
I have modified the docker compose file located in the Uptime Kuma repository to work with Traefik as a reverse proxy. I have also bound the docker socket to the container so that it can monitor the status of other containers on the virtual machine.
The process I followed for installing Uptime Kuma is as follows:
- Create a directory for the Uptime Kuma data
mkdir uptimekuma- Create a docker-compose.yml file with the contents below
version: "3.8"
services: uptime-kuma: image: louislam/uptime-kuma:1 container_name: uptime-kuma volumes: - /var/run/docker.sock:/var/run/docker.sock:ro - ./uptimekuma/uptime-kuma-data:/app/data restart: always security_opt: - no-new-privileges:true networks: - proxy labels: - "traefik.enable=true" - "traefik.http.routers.uptime.entrypoints=http" - "traefik.http.routers.uptime.rule=Host(`your-hostname.yourdomain.tld here`)" - "traefik.http.middlewares.uptime-https-redirect.redirectscheme.scheme=https" - "traefik.http.routers.uptime.middlewares=uptime-https-redirect" - "traefik.http.routers.uptime-secure.entrypoints=https" - "traefik.http.routers.uptime-secure.rule=Host(`your-hostname.yourdomain.tld here`)" - "traefik.http.routers.uptime-secure.tls=true" - "traefik.http.routers.uptime-secure.service=uptime" - "traefik.http.services.uptime.loadbalancer.server.port=3001" - "traefik.docker.network=proxy"networks: proxy: external: trueTip (Traefik Reverse Proxy)
This assumes that you have a Traefik container running on the same host machine. If you are not running traefik as a reverse proxy, you can remove the labels section from the docker-compose.yml file and add a section to expose the appropriate ports. You will then need to access the Uptime Kuma web interface by going to http://HOST_IP:3001
- Run the docker-compose.yml file with the following command
docker compose up -dTip (Docker Compose CLI Options)
The -d option will start the Uptime Kuma container in the background
- Access the Uptime Kuma web interface by going to https://SUB_DOMAIN.YOUR_DOMAIN.com
- After initial configuration the Uptime Kuma web interface looks similar to the following:

Extras
Discord Notifications
Some other functionality that I have found useful is the ability to send notifications via discord. This can be configured by going to the settings page and selecting the notifications tab. You will need to create a discord webhook and paste the URL into the discord webhook field. The message prefix shown below is an example of how to notify a specific role in a discord server.

Here is an example of what the notification looks like in discord. This has been used at various CTF competitions at TU to nofity the team when a challenge is down.
