uptimekuma Setup

In this tutorial we're going to setup Uptime Kuma to monitor services.

Initial Setup

Install it using git and run it with docker:


apt install docker.io docker-compose -y

[ 10.8.0.2/24 ] [ home ] [/srv/uptimekuma]
→ cat docker-compose.yml
version: '3.3'

services:
  uptime-kuma:
    image: louislam/uptime-kuma:1
    container_name: uptime-kuma
    volumes:
      - ./uptime-kuma-data:/app/data
    ports:
      - 3001:3001
    restart: always


[ 10.8.0.2/24 ] [ home ] [/srv/uptimekuma]
→ docker-compose up -d

[ 10.8.0.2/24 ] [ home ] [/srv/uptimekuma]
→ ls
docker-compose.yml  uptime-kuma-data

→ ls -lash uptime-kuma-data

[ 10.8.0.2/24 ] [ home ] [/srv/uptimekuma]
→ nmap 127.0.0.1 -p 3001
Starting Nmap 7.93 ( https://nmap.org ) at 2023-07-23 16:58 CEST

Next you can put it behind a reverse nginx proxy and use it:


[ 10.8.0.2/24 ] [ home ] [/srv/uptimekuma]
→ systemctl stop nginx

[ 10.8.0.2/24 ] [ home ] [/srv/uptimekuma]
→ acme.sh --issue --standalone -d status.nowhere.moe -k 4096

[ 10.8.0.2/24 ] [ home ] [/etc/nginx/sites-available]
→ vim status.nowhere.moe.conf

[ 10.8.0.2/24 ] [ home ] [/etc/nginx/sites-available]
→ cat status.nowhere.moe.conf
upstream statusbackend {
        server 127.0.0.1:3001;
}

server {
        listen 80;
        listen [::]:80;
        server_name status.nowhere.moe;
        return 301 https://$server_name$request_uri;
}

server {
        listen 443 ssl http2;
        listen [::]:443 ssl http2;
        server_name status.nowhere.moe;

        ssl_certificate /root/.acme.sh/status.nowhere.moe/fullchain.cer;

                proxy_set_header Connection "Upgrade";
        }
}

[ 10.8.0.2/24 ] [ home ] [/etc/nginx/sites-available]
→ ln -s /etc/nginx/sites-available/status.nowhere.moe.conf /etc/nginx/sites-enabled

[ 10.8.0.2/24 ] [ home ] [/etc/nginx/sites-available]
→ nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

[ 10.8.0.2/24 ] [ home ] [/srv/uptimekuma]
→ systemctl start nginx

From there we're going to add hosts to check the uptime:

To make it more organised we'll create a status page for a group of hosts to monitor:

And in here we're going to add hosts to track

We can also add tcp-specific ports like 18081 monero node:

After populating them it looks like so:

Next step: monitoring onion services:

Then you need to make sure that the docker container can access the tor socks proxy port on the host machine like so:


[ 10.8.0.2/24 ] [ home ] [~]
→ cat /etc/tor/torrc | grep 9050
SocksPort 0.0.0.0:9050

[ 10.8.0.2/24 ] [ home ] [~]
→ systemctl restart tor@default

[ 10.8.0.2/24 ] [ home ] [~]
→ systemctl status tor@default

Then if you want to make your dashboards available for the public you just give them the link to your status pages like the ones below:

nowhere.moe Status page https://status.nowhere.moe/status/daturanetwork

nowhere.moe Status page https://status.nowhere.moe/status/nihilismnetwork



UPDATE NOTE: if your docker container gets updated and the database gets corrupted, you're going to need to go to dashboard > settings > backup > export backup (json file) > docker-compose down, delete the uptimekuma data floder > docker-compose up -d --force-recreate > then you need to go create the admin account again, then go to settings backup import backup (json file) and need to redo the status pages.

The reason for this is the developers do database changes from a version to the next without caring about database breaking changes. Hence need to do all this to fix an uptimekuma upgrade db failure
