Selfhosted

i like kuma. simple, flexibel, selfhosted, and open source. one thing i missed is an API for adding / modifing hosted services.

now, i found a webapi for kuma and gave a try.

pre-condition

you have some Maschine with Docker
you have traefik running, which can terminate TLS, handle Loadbalancing

docker-compose.yml

version: '3.3'

networks:
  traefik:
    external: true

volumes:
  uptime-kuma:
  api-db:

services:
  kuma:
    container_name: uptime-kuma
    image: louislam/uptime-kuma:1.19.6
    restart: always
    volumes:
      - uptime-kuma:/app/data
    networks:
      - traefik
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.kuma.rule=Host(`kuma.your.domain`)"
      - "traefik.http.routers.kuma.tls=true"

  api:
    container_name: backend
    image: medaziz11/uptimekuma_restapi:latest
    restart: always
    volumes:
      - ./db:/db:rwx
    environment:
      - KUMA_SERVER=${KUMA_SERVER:-http://kuma:3001}
      - KUMA_USERNAME=xxxxxx
      - KUMA_PASSWORD=xxxxxx
      - ADMIN_PASSWORD=xxxxxx
      - SECRET_KEY=${SECRET_KEY:-xxxxxx}
    depends_on:
      - kuma
    networks:
      - traefik

Get Token

# API
token=$(http --form POST 127.0.0.1:8001/login/access-token 'username=xxxxxx' 'password=xxxxxx' |jq '.access_token')

List Monitors

$ http -A bearer -a $token 127.0.0.1:8001/monitors
HTTP/1.1 200 OK
content-length: 15
content-type: application/json
date: Mon, 17 Apr 2023 04:48:59 GMT
server: uvicorn

{
    "monitors": []
}

Add Service

$ http -A bearer -a $token 127.0.0.1:8001/monitors type=http name=compass url=https://www.compass-security.com

{
    "monitorID": 5,
    "msg": "Added Successfully."
}

Check Monitoring

$ http -A bearer -a $token 127.0.0.1:8001/monitors |jq '.monitors |map({id, name, url, active, interval})'
[
  {
    "id": 1,
    "name": "https://www.stoege.net",
    "url": "https://www.stoege.net",
    "active": true,
    "interval": 60
  },
  ... snip ...
  {
    "id": 5,
    "name": "compass",
    "url": "https://www.compass-security.com",
    "active": true,
    "interval": 60
  }
]
