Only - Packer — ContextQMD

-only=foo,bar,baz - Only run the builds with the given comma-separated names. In legacy JSON templates, build names default to the types of their builders (e.g. docker or amazon-ebs or virtualbox-iso), unless a specific name attribute is specified within the configuration. In HCL2 templates, the "name" is the source block's "name" label, unless an in-build source definition adds the "name" configuration option.
