The Using tags in Puppet Bolt aws_inventory target_mapping showed how to use AWS "Name" tag as the target name for Puppet Bolt. Use of tags can be extended to creating Bolt target groups:
groups: - name: webservers targets: - _plugin: aws_inventory region: _plugin: env_var var: AWS_DEFAULT_REGION filters: - name: tag:Type values: [webserver] target_mapping: name: tags.Name uri: public_ip_address
All you need to do is add a "filter" section with one filter. The "name" parameter tells Bolt that the filter is based on tags and what tag to look for. The "Type" that follows "tag" is the name of the tag you want to filter by. The "values" array lists acceptable values for that tag. Any nodes that don't have the tag (here: "Type") or where tag value is not acceptable (e.g. "db") will not be shown in the group.
