If you're packaging up applications in debian packages,
you'll most likely be running dpkg-buildpackage to build them.
This container allows you to mount your project and build it.
Inside the repo where the debian folder is, run:
docker run -v $(pwd):/package -it -e ghcr.io/lion7/dpkg-buildpackage
By default, it runs with the following arguments:
-us -uc
You can override these defaults by adding them to the end of the command:
docker run -v $(pwd):/package -it ghcr.io/lion7/dpkg-buildpackage -rfakeroot
