[Wolfi Package Request]: micromamba

[rigzba21]

What software would you like us to add to wolfi-os. Ideally include a URL to the project and its source.

• https://mamba.readthedocs.io/en/latest/user_guide/mamba.html
• https://mamba.readthedocs.io/en/latest/installation/micromamba-installation.html
• https://github.com/mamba-org/mamba/tree/main

which versions of the software should we include?

Latest: https://github.com/mamba-org/mamba/releases/tag/2023.12.21

Add some justification for why this specific package and versions are important.

micromamba is a self-contained statically-linked executable for managing and working with conda environments, with a key difference being the base conda environment is empty.

From https://mamba.readthedocs.io/en/latest/user_guide/micromamba.html#micromamba-user-guide

micromamba is a tiny version of the mamba package manager. It is a statically linked C++ executable with a separate command line interface. It does not need a base environment and does not come with a default version of Python.

It's a smaller alternative to conda, and works well in constrained environments due to micromamba not requiring a default version of python or default packages in the base conda environment. #4888 is an example related to the default bundled python and associated base environment packages.

I'm happy to submit a PR for this, though I'm new to working with Wolfi OS. Thanks!

Please check all that apply

• This package has an un-restrictive license
• The package/versions proposed are actively maintained upstream
• I am interested in adding this package to Wolfi OS myself
• I am willing to help maintain this package

Is there a getting started with adding new packages guide? I'm new to the wolfi-os/apko/melange ecosystem.

I found it: https://edu.chainguard.dev/open-source/wolfi/building-a-wolfi-package/

I am interested in this proposal, is there anything I can help with?
I can also take over this task should you do not mind it :-)

I can also take over this task should you do not mind it :-)

Please do so! I currently do not have the time to dedicate to this.
