How to Resolve Manually

A task definition is a blueprint for your application. It is a text file in JSON format that describes the parameters and one or more containers that form your application.

This config rules checks if log configuration property exists in the latest active version of a Task Definition. The rule will be marked non-compliant if there isn't any kind of logging configured for the task definition.


In order to resolve this you will need to create a new revision for your particular non-compliant task definition. To do so head on over to the Elastic Container Service (ECS) and click on Task definitions from the left menu. From the list, click on the definition that is not compliant and then choose the latest revision.

At the properties screen, if you click on the JSON tab, you can check that the 'logConfiguration' parameter is not present.

To resolve the issue, click on Create New Revision button at the top right, then you can select Create new revision with JSON to use the current JSON definition as a baseline. Once there, you can configure the logging type that better suits your organization's needs. You can check this AWS article for further reference.
