This article explains how to install Uptime Kuma with Caddy. Uptime Kuma is a self-hosted monitoring tool like "Uptime Robot". Caddy 2 is a powerful, enterprise-ready, open source web server with automatic HTTPS written in Go.
You need a freshly installed Ubuntu 20.04 cloud server. It should have a minimum of 1 vCPU, 10 GB of storage, and 512 MB of RAM. For best performance, 1 GB or RAM or more is recommended.
Update the server.
$ apt update && apt upgrade -y
Install Docker.
$ apt install docker.io -y
Create a volume for Uptime Kuma.
$ docker volume create uptime-kuma
Start the container.
$ docker run -d --restart=always -p 3001:3001 -v uptime-kuma:/app/data --name uptime-kuma louislam/uptime-kuma:1
Update Uptime Kuma
$ docker pull louislam/uptime-kuma:1
$ docker stop uptime-kuma
$ docker rm uptime-kuma
$ docker run -d --restart=always -p 3001:3001 -v uptime-kuma:/app/data --name uptime-kuma louislam/uptime-kuma:1
Install Caddy
$ sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https
$ curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | $ sudo tee /etc/apt/trusted.gpg.d/caddy-stable.asc

Setting up your VPS is pretty simple. We will go through things like Changing SSH port, allowing certain ports via UFW and more.
Start by opening the configuration file with nano or your preferred text editor.
$ sudo nano /etc/ssh/sshd_config
Uncomment the #Port 22
line and change the port to 1337.
Change:
#Port 22
To:
Port 1337
Save the changes youâve made to this file and exit.
Finish up by reloading the sshd service.
$ sudo systemctl reload sshd
Configure the firewall.
$ ufw allow 8001/tcp && ufw allow 8001/udp
$ ufw allow 80/tcp && ufw allow 80/udp
$ ufw allow 443/tcp
To make Uptime Kuma work with a Fully-Qualified Domain Name and Cloudflare DNS you need to edit the Caddyfile.
$ nano /etc/caddy/Caddyfile
Delete everything in the file and replace it with:
subdomain.domain.com {
reverse_proxy 127.0.0.1:3001
}
If the website wont load, follow these steps:
$ pkill nginx
$ pkill caddy
$ sudo service caddy start
