AUTOKUMA__KUMA__USERNAME kuma.username The username for logging into Uptime Kuma (required unless auth is disabled)
AUTOKUMA__KUMA__PASSWORD kuma.password The password for logging into Uptime Kuma (required unless auth is disabled)
AUTOKUMA__KUMA__MFA_TOKEN kuma.mfa_token The MFA token for logging into Uptime Kuma (required if MFA is enabled)
AUTOKUMA__KUMA__HEADERS kuma.headers List of HTTP headers to send when connecting to Uptime Kuma
AUTOKUMA__KUMA__CONNECT_TIMEOUT kuma.connect_timeout The timeout for the initial connection to Uptime Kuma
AUTOKUMA__KUMA__CALL_TIMEOUT kuma.call_timeout The timeout for executing calls to the Uptime Kuma server
AUTOKUMA__DOCKER__HOSTS docker.hosts List of Docker hosts. Use a semicolon separated string when setting using an env variable.
AUTOKUMA__DOCKER__LABEL_PREFIX docker.label_prefix Prefix used when scanning for container labels
AUTOKUMA__DOCKER__SOURCE docker.source Whether monitors should be created from Containers or Services labels (or Both).
AUTOKUMA__DOCKER__TLS__VERIFY docker.tls.verify Whether to verify the TLS certificate or not.
AUTOKUMA__DOCKER__TLS__CERT docker.tls.cert The path to a custom tls certificate in PEM format.

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

Platform Value Example
Linux $XDG_CONFIG_HOME/autokuma/config.{toml,yaml,json} /home/alice/.config/autokuma/config.toml
macOS $HOME/Library/Application Support/autokuma/config.{toml,yaml,json} /Users/Alice/Library/Application Support/autokuma/config.toml
Windows %LocalAppData%\autokuma\config.{toml,yaml,json} C:\Users\Alice\AppData\Local\autokuma\config.toml

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>

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 entity types and their corresponding settings.

Groups

To assign a monitor to a group set it's parent_name property to the autokuma id of the group, e.g.

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'

Notifications

WARNING: Defining Notifications is currently experimental and might change in the future.

kuma.mynotificationprovider.notification.name: 'This is a Matrix notification provider'
kuma.mynotificationprovider.notification.active: 'true'
kuma.mynotificationprovider.notification.config: '{"type": "matrix", "accessToken": "XXXXXXXXXXXXXXXXXX", "homeserverUrl": "https://matrix.org", "internalRoomId": "!xxxxxxxxxxxxxxxxxx:matrix.org"}'

kuma.mymonitor.http.name: 'This is a Monitor with a notification provider'
kuma.mymonitor.http.notification_names: '["mynotificationprovider"]'
kuma.mymonitor.http.url: 'https://example.com'

Docker Hosts

WARNING: Defining Docker Hosts is currently experimental and might change in the future.

kuma.mydocker.docker_host.name: 'My Docker Host'
kuma.mydocker.docker_host.connection_type: 'socket'
kuma.mydocker.docker_host.path: '/var/run/docker.sock'

kuma.mymonitor.http.name: 'This is a Docker Monitor'
kuma.mymonitor.http.docker_host_name: 'mydocker'
kuma.mymonitor.http.url: 'https://example.com'

Tags

WARNING: Defining Tags is currently experimental and might change in the future.

kuma.mytag.tag.name: 'A purple label'
kuma.mytag.tag.color: '#FF00FF'

kuma.mymonitor.http.name: 'This is a Monitor with a label'
kuma.mymonitor.http.tag_names: '[{"name": "mytag", "value": "A value (this is optional)" }]'
kuma.mymonitor.http.url: 'https://example.com'

Templating

AutoKuma allows the usage of Tera templates in labels and Snippets, the following variables are available: Template Description Example Value
Containers
container_id The container id 92366941fb1f211c573c56d261f3b3e5302f354941f2aa295ae56d5781e97221
image_id Sha256 of the container image sha256:c2e38600b252f147de1df1a5ca7964f9c8e8bace97111e56471a4a431639287a
image Name of the container image ghcr.io/immich-app/immich-server:release
container_name Name of the container immich-immich-1
container Nested structure with container details See the Docker Engine Documentation for the available data
system_info Nested structure with host details See the Docker Engine Documentation for the available data
Services
service Nested structure with service details See the Docker Engine Documentation for the available data
system_info Nested structure with host details See the Docker Engine Documentation for the available data

Snippets 📝

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:

Platform Value Example
Linux $XDG_CONFIG_HOME/autokuma/static-monitors/ /home/alice/.config/autokuma/static-monitors/
macOS $HOME/Library/Application Support/autokuma/static-monitors/ /Users/Alice/Library/Application Support/autokuma/static-monitors/
Windows %LocalAppData%\autokuma\static-monitors\ C:\Users\Alice\AppData\Local\autokuma\static-monitors\

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