UptimeKuma

uptime-kuma is like UptimeRobot, except free :-)

Here's how I set it up with Caddy to have UptimeKuma run with an SSL cert!

Run it in one window/terminal

docker run -d --restart=always -p 3001:3001 -v uptime-kuma:/app/data --name uptime-kuma louislam/uptime-kuma:2

Update it

Info taken from here:

# Shutdown tailscale if it's in use
# sudo tailscale down
sudo docker pull louislam/uptime-kuma:2
sudo docker stop uptime-kuma
sudo docker rm uptime-kuma
# sudo tailscale up - if it's connected to a Tailscale network

# Run with default settings:
docker run -d --restart=always -p 3001:3001 -v uptime-kuma:/app/data --name uptime-kuma louislam/uptime-kuma:2

Run Caddy server in another window/terminal

Create a Caddy file that looks something like this:

mykuma.mydomain.com {
        reverse_proxy 127.0.0.1:3001
        
        log {
                output file /var/log/caddy/mykuma.log
        }

}

Then run it:

sudo caddy run --config Caddyfile
