Updating groups in AWS Resource Groups

To update a tag-based resource group in Resource Groups, you can edit the query and tags that are the basis of your group. You can add and remove resources from your group only by applying changes to the query or tags. You cannot select specific resources to add to or remove from your group. The best way to add or remove a specific resource from a group is to edit the resource's tags. Then verify that your resource group tag query either includes or omits the tag, depending on whether you want the resource in your group.

To update an AWS CloudFormation stack-based resource group, you can choose a different stack. You can also add or remove resource types from the stack that you want to be part of the group. To change the resources that are available in the stack, update the AWS CloudFormation template used to create the stack, and then update the stack in AWS CloudFormation. For more information about how to update an AWS CloudFormation stack, see AWS CloudFormation stacks updates in the AWS CloudFormation User Guide.

In the AWS CLI, you update groups in two commands.

In the console, you cannot change an AWS CloudFormation stack-based group to a tag-based query group, or vice versa. However, you can do this by using the Resource Groups API, including in the AWS CLI.
