ytt supports two different output destinations:
- stdout, which is default
- output directory, controlled via
--output-directory
When destination is stdout, all YAML documents are combined into one document set. Non-yaml files are not printed anywhere.
When destination is an output directory, ytt will empty out directory beforehand and write out result files preserving file names.
If you want to control which files are included in the output use --file-mark 'something.yml:exclusive-for-output=true' flag to mark one or more files.
