Hammer

Hammer takes YAML specs and uses them to build packages (with FPM.) Here's a pretty minimal example, please see the docs for more information.

When saved as spec.yml in some folder, Hammer will find and execute it, producing a package. Most fields are templated, and you can use Go templates to get fields on the Package struct.

Installation

First, you'll need to get FPM (which should just be gem install fpm) and any build tools you need (for example, to build RPMs you'll need rpmbuild.) Then, go install github.com/asteris-llc/hammer.

Contributing

Got a feature you'd like to see? PRs are very welcome. Just make sure that your build passes all the checks on gometalinter. Tests are appreciated, as well!
