Exploration: Enabling Tiny as a Target Stack #323

ryanmoran · 2020-09-17T22:42:47Z

Exploration Summary

Enabling support for running .Net Core applications on top of the Tiny stack required only a few, relatively simple changes to the existing buildpacks. I've outlined those changes below, but in summary, we need to 1) update the stack references that are supported across all the buildpack.toml files, 2) make some small changes to the internal implementatons to support running on top of a stack that does not have a shell, and 3) include a couple of new packages in the Tiny Run Image that are required at runtime.

I believe the biggest hurdle to supporting .Net Core applications on Tiny is the conversation around the additions to the Tiny stack. I don't know much about the goals of Tiny and whether these additions would be welcome or considered to be outside of the scope of the stack. FWIW, the additions here seem to only amount to an ~2MB increase in the stack image size.

After the exploration, I happened upon a list of prerequisites for Linux systems. The section on Alpine likely approximates much of what we are trying to do with Tiny. In that section, there are more than just the 2 libraries I found to be required. It is unclear what from this list would need to be pulled into Tiny.
