Project Description

I recently used melange and apko to build a from scratch image. The result was a set of auditable and easy to use container and apk repository. The toolkit reduces the work need to make from scratch images with minimal work on the actual docker container(which can be quite painful if you've tried making a from scratch image on your own).

The end goal would be to produce 2 utilities. 1. A utility that can build rpms from yaml thus simplifying the rpm building process. This would not aim to replace the entire rpm spec but rather be a subset of functionality and will not include macros for now. The counterpart to this utility would another utility to produce a container image including a minimal set of dependencies from the opensuse repos.

As for the language used for the project, I believe rust will be a good choice, it provides enough flexibility along with a large collection of utilities we can use for this including but not limited to, rpm, oci-spec-rs along with compile time checks to speed up the development process

Goals for this Hackweek

The goals for this hackweek for the rpm utility are the following: 1. produce a signing keypair for packages 2. run a set of commands to produce a binary/lib that can be copied to a directory that will be converted to a rpm 3. output a rpm 4. make a rpm repository that can be used by the container utility

The goals for the container utility are the following: 1. build a container from a repository 2. output the container as a tarball 3. publish the container to a repo
