Method: ActiveEncode::EngineAdapters::MediaConvertAdapter#setup!

Defined in:
lib/active_encode/engine_adapters/media_convert_adapter.rb

#setup! ⇒ Object

Creates a [CloudWatch Logs] (aws.amazon.com/cloudwatch/) log group and an EventBridge rule to forward status change notifications to the log group, to catch result information from MediaConvert jobs.

Will use the configured queue and log_group values.

The active AWS user/role when calling the #setup! method will require permissions to create the necessary CloudWatch and EventBridge resources

This method chooses a conventional name for the EventBridge rule, if a rule by that name already exists, it will silently exit. So this method can be called in a boot process, to check if this infrastructure already exists, and create it only if it does not.
