Support alpine Docker image environment about ruby-packer HOT 5 CLOSED

I've seen this same issue building go binaries on the ubuntu:16.04 image and trying to run them on the alpine:latest image.

Some googling suggests installing libc6-compat may allow you to run rubyc?

Looked into those glibc dynamic linking workarounds and they do not seem to be working in this situation.

Should I be looking into other software for lightweight Ruby software packaging and containerization, or is there interest in first party support for this?

I know Hashi just released a Vagrant version packaged with AppImage so that route may work.

I don't know what is different about the alpine linux environment and unfortunately I don't have the time to figure out how to get the packaged rubyc to work in it.

You can define a Dockerfile that builds rubyc under alpine, then uses that rubyc to package your application, then copies the packaged application to a standalone image. I have added some instructions for building rubyc yourself to the README that may get you started.

Since you need the same toolchain for building your own rubyc and for packaging your application with rubyc the main downside is the extra time spent building rubyc. Of course, you can store your alpine-compatible rubyc to save time.

Sure, if the AppImage route does not work I will look at building rubyc with musl links.
Thanks.

Great, thanks for the feedback, and let us know if we can improve the build instructions!
