The Clever Guide: Install Uptime Kuma with Caddy on Ubuntu 20.04

Uptime Kuma is a powerful open-source monitoring tool that allows you to track the uptime and performance of your websites and servers. To ensure seamless access and secure the installation, we will use Caddy, a lightweight web server and reverse proxy. This comprehensive guide will walk you through the step-by-step process of Install Uptime Kuma with Caddy on Ubuntu 20.04, enabling you to monitor your websites and servers with ease.

Prerequisites

– A Linux VPS server running Ubuntu 20.04 with root access or a user with sudo privileges.

– Minimum of 1 vCPU, 10 GB of storage, and 1 GB of RAM.

– A domain name pointing to your server’s IP address.

Install and Configure Caddy

To install Caddy, you can follow the following steps in order:

sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https

curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg

curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-stable.list

sudo apt update

sudo apt install caddy

Now that Caddy is installed, we need to configure it to serve Uptime Kuma efficiently.

Open the Caddyfile using the following command:

sudo nano /etc/caddy/Caddyfile

Edit the file with the following content:

your-domain.com {
reverse_proxy localhost:3000
}

Save the file and exit the text editor. (Ctrl+X and then press enter)

Restart the Caddy service using the following command:

sudo systemctl restart caddy

Install and Set Up Uptime Kuma

Now, you can Install Uptime Kuma with Caddy on Ubuntu using the following steps.

First, update the server by running the following commands:

sudo apt update
sudo apt upgrade

Now, you should install Docker using below command:

apt install docker.io -y

Then, you can create a volume for Uptime Kuma using the following command:

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

Finally, its time to 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

Configure Uptime Kuma

At the beginning of this section, we want to configure SSH and firewall. To do this, open the configuration file using the following command:

sudo nano /etc/ssh/sshd_config

Uncomment the following line, then change it to 1337:

#Port 22
To:
Port 1337 

Save the configuration file and exit.

Reload the sshd service with the help of the following command:

sudo systemctl reload sshd

Finally, you can configure the firewall as follows:

ufw allow 8001/tcp && ufw allow 8001/udp

ufw allow 80/tcp && ufw allow 80/udp

ufw allow 443/tcp

You need to configure Kuma Uptime so that a fully qualified domain name and Cloudflare DNS work. To do this, you can edit the Caddyfile using the following command:

nano /etc/caddy/Caddyfile

Finally, delete the contents of the file completely and replace it with the following commands:

subdomain.domain.com {
reverse_proxy 127.0.0.1:3001
}
