AutoKuma 🐻

AutoKuma is a utility that automates the creation of Uptime Kuma monitors based on Docker container labels. With AutoKuma, you can eliminate the need for manual monitor creation in the Uptime Kuma UI.

How to Install 📦

Supported Platforms

Binaries for windows linux and mac are provided for GitHub Releases, additionally AutoKuma is available as a Docker container on GitHub Container Registry (GHCR). To install, simply pull the container using:

Latest Release:

docker pull ghcr.io/bigboot/autokuma:latest

Dev Version:

docker pull ghcr.io/bigboot/autokuma:master

❗ The dev version might break or contain breaking changes without warning, usage on a production system is not adviced.

Example Docker Compose 🚀

Here's an example docker-compose.yml:

version: '3'

services:

      #    *.max_retries: 3
      # AUTOKUMA__SNIPPETS__WEB: |- 
      #    {{container_name}}_http.http.name: {{container_name}} HTTP
      #    {{container_name}}_http.http.url: https://{{@0}}:{{@1}}
      #    {{container_name}}_docker.docker.name: {{container_name}} Docker
      #    {{container_name}}_docker.docker.docker_container: {{container_name}}
      # AUTOKUMA__DOCKER__HOSTS: unix:///var/run/docker.sock
      # AUTOKUMA__DOCKER__LABEL_PREFIX: kuma
      
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

Configuration 🔧

AutoKuma can be configured using the following environment variables/config keys:

AutoKuma will read configuration from a file named autokuma.{toml,yaml,json} in the current directory and in the following locations:

An example .toml config could look like the following:

[kuma]
url = "http://localhost:3001/"
username = "<username>"
password = "<password>"

Usage 💡

AutoKuma interprets Docker container labels with the following format:

<prefix>.<id>.<type>.<setting>: <value>

• <prefix>: Default is kuma unless changed using the DOCKER__LABEL_PREFIX env variable.
• <id>: A unique identifier for the monitor (ensure it's unique between all monitors).
• <type>: The type of the monitor as configured in Uptime Kuma.
• <setting>: The key of the value to be set.
• <value>: The value for the option.

Labels are grouped by <id> into a single monitor. For example, to create a simple HTTP monitor, use the following labels:

kuma.example.http.name: "Example"
kuma.example.http.url: "https://example.com"

Take a look at all available monitor types and the corresponding settings.

AutoKuma also provides support for creating and assigning groups:

kuma.mygroup.group.name: "This is a Group"
kuma.mymonitor.http.name: "This is a Monitor assigned to a Group"
kuma.mymonitor.http.parent_name: "mygroup"
kuma.mymonitor.http.url: "https://example.com"

AutoKuma allows the usage of Tera templates in labels and Snippets, the following variables are available:

Snippets 📝

WARNING: Snippets are currently experimental and might change in the future.

AutoKuma provides the ability to define reusable snippets. Snippets need to be defined in the configuration, for example, using environment variables:

AUTOKUMA__SNIPPETS__WEB: |-
    {{ container_name }}_http.http.name: {{ container_name }} HTTP
    {{ container_name }}_http.http.url: https://{{ args[0] }}:{{ args[1] }}
    {{ container_name }}_docker.docker.name: {{ container_name }} Docker
    {{ container_name }}_docker.docker.docker_container: {{ container_name }}

or in an equivalent TOML config file:

[snippets]
web = '''
    {{ container_name }}_http.http.name: {{ container_name }}
    {{ container_name }}_http.http.url: https://{{ args[0] }}:{{ args[1] }}
    {{ container_name }}_docker.docker.name: {{ container_name }}_docker
    {{ container_name }}_docker.docker.docker_name: {{ container_name }}
'''

These define a snippet called web.

A snippet can have a variable number of arguments, which are available as replacements using {{ args[0] }}, {{ args[1] }}, {{ args[2] }}, etc., as seen above.

To use a snippet on a container, assign a label in the format:

<prefix>.__<snippet>: <arguments>

For example, the above snippet could be included using the following label:

kuma.__web: '"example.com", 443'

Snippets also use Tera, which allows for some quite advanced templates, here's a extended variation of the above example:

{# Assign the first snippet arg to args to make access easier #}
{% set args = args[0] %}

{# Generate an autokuma id by slugifying the "name" arg #}
{% set id = args.name | slugify %}

{# if we have a "keyword" generate a "keyword" monitor, otherwise generate a "http" monitor #}
{% if args.keyword %}
    {% set type = "keyword" %}
{% else %}
    {% set type = "http" %}
{% endif %}


{# below are the actual lines which end up defining the monitor #}
{{ id }}-group.group.name: {{ args.name }}
{{ id }}-http.{{ type }}.name: {{ args.name }} (HTTP)
{{ id }}-http.{{ type }}.parent_name: {{ id }}-group
{{ id }}-http.{{ type }}.url: {{ args.url }}
{% if args.keyword %}
    {{ id }}-http.{{ type }}.keyword: {{ args.keyword }}
{% endif %}
{% if args.status_code %}
    {{ id }}-http.{{ type }}.status_code: {{ args.status_code }}
{% endif %}
{{ id }}-http-container.docker.name: {{ args.name }} (Container)
{{ id }}-http-container.docker.parent_name: {{ id }}-group

And the usage of it would be like the following: Just a basic http monitor:

kuma.__web: '{ "name": "Example HTTP", "url": "https://example.com" }'

Keyword monitor with custom status_codes:

kuma.__web: '{ "name": "Example HTTP", "url": "https://example.com", "keyword": "Example Domain", "status_codes": ["200"] }'

Static Monitors 📊

In addition to reading Monitors from Docker labels, AutoKuma can create Monitors from files. This can be usefull if you have want AutoKuma to manage monitors which aren't directly related to a container.

To create static Monitors just add a .json or .toml file in the directory specified by AUTOKUMA__STATIC_MONITORS, take a look at the examples here.

The default directory for static monitors is:

In case of static Monitors the id is determined by the filename (without the extension).
