Module: cloudwatch_event_target

Associates an EventBridge rule with a target: Lambda function, SSM runbook (Automation document), or direct ARN.

Input Map Key Pattern

Root variable: eb_targets (map of objects). Each key becomes a target logical name.

Field	Type	Required	Description
rule	string	required	Key of the associated eb_rules entry
lambda_function	string	conditional	Name/key of lambda (if targeting lambda)
ssm_runbook	string	conditional	Key of runbook module (if invoking SSM Automation)
arn	string	conditional	Direct target ARN (fallback)
role_arn	string	optional	Role for EventBridge to assume (e.g., SSM automation)
input	string	optional	Static JSON payload
input_path	string	optional	JSONPath to extract part of event
input_transformer	object	optional	Advanced input mapping

Exactly one of lambda_function, ssm_runbook, or arn must be set.

Resolution Logic

1. If lambda_function provided, resolves to lambda function ARN.
2. Else if ssm_runbook provided, resolves to SSM document ARN.
3. Else uses arn directly.

Naming

Rule derived unless explicitly provided: ${prefixes.eb_rule}${key}${suffixes.eb_rule}.

Example

eb_targets = {
  shutdown_target = {
    rule          = "nightly_shutdown"
    ssm_runbook   = "Stop-Instances-Runbook-TF"
    role_arn      = "EventBridge_SSM_AutomationRole"
  }
}
