The eventbridge component is a Terraform module that defines a CloudWatch EventBridge rule. The rule is pointed at cloudwatch by default.

Usage

Stack Level: Regional

Here's an example snippet for how to use this component.

components:
  terraform:
    eventbridge/ecs-alerts:
      metadata:
        component: eventbridge
      vars:
        name: ecs-faults
        enabled: true
        cloudwatch_event_rule_description: "ECS failures and warnings"
        cloudwatch_event_rule_pattern:
          source:
            - aws.ecs
          detail:
            $or:

<a name="input_additional_tag_map"></a> additional_tag_map	Additional key-value pairs to add to each map in `tags_as_list_of_maps`. Not added to `tags` or `id`.<br>This is for some rare cases where resources want additional configuration of tags<br>and therefore take a list of maps with tag key, value, and additional configuration.	`map(string)`	`{}`	no
<a name="input_attributes"></a> attributes	ID element. Additional attributes (e.g. `workers` or `cluster`) to add to `id`,<br>in the order they appear in the list.

<a name="input_context"></a> context	Single object for setting entire context at once.<br>See description of individual variables for details.<br>Leave string and numeric variables as `null` to use default value.<br>Individual variable settings (non-null) override settings in context object,<br>except for attributes, tags, and additional_tag_map, which are merged.	`any`	<pre>{<br> "additional_tag_map": {},<br> "attributes": [],<br> "delimiter": null,<br> "descriptor_formats": {},<br> "enabled": true,<br> "environment": null,<br> "id_length_limit": null,<br> "label_key_case": null,<br> "label_order": [],<br> "label_value_case": null,<br> "labels_as_tags": [<br> "unset"<br> ],<br> "name": null,<br> "namespace": null,<br> "regex_replace_chars": null,<br> "stage": null,<br> "tags": {},<br> "tenant": null<br>}</pre>	no
<a name="input_delimiter"></a> delimiter	Delimiter to be used between ID elements.<br>Defaults to `-` (hyphen). Set to `""` to use no delimiter at all.	`string`	`null`	no
<a name="input_descriptor_formats"></a> descriptor_formats	Describe additional descriptors to be output in the `descriptors` output map.<br>Map of maps. Keys are names of descriptors. Values are maps of the form<br>`{<br> format = string<br> labels = list(string)<br>}`<br>(Type is `any` so the map values can later be enhanced to provide additional options.)<br>`format` is a Terraform format string to be passed to the `format()` function.<br>`labels` is a list of labels, in order, to pass to `format()` function.<br>Label values will be normalized before being passed to `format()` so they will be<br>identical to how they appear in `id`.<br>Default is `{}` (`descriptors` output will be empty).	`any`	`{}`	no

<a name="input_label_value_case"></a> label_value_case	Controls the letter case of ID elements (labels) as included in `id`,<br>set as tag values, and output by this module individually.<br>Does not affect values of tags passed in via the `tags` input.<br>Possible values: `lower`, `title`, `upper` and `none` (no transformation).<br>Set this to `title` and set `delimiter` to `""` to yield Pascal Case IDs.<br>Default value: `lower`.	`string`	`null`	no
