@xuan-cao-swi thank you for the contribution! It's clear you put a lot of effort into it.

That said, before we can proceed with code review, we'll need to discuss how exactly we want to go about introducing this new autoinstrumentation to the operator. Could you open an issue and describe how it works? Adding a new instrumentation is a very big change with major implications for the maintainability of this project, and we need to make sure we do it right.

Would it make sense for you to step up as codeowner of those files moving forward to help maintain Ruby auto-instrumentation?

Yes, I'd like to help maintain the ruby auto-instrumentation.

I've added this point to the agenda for today's SIG meeting. Anyone interested is encouraged to join in on the discussion. You can find the calendar here.

We have a pattern for test e2e-instrumentation apps

Thanks @jaronoff97 , I have the e2e instrumentation test case ready. Once this one get accepted/merged, I will create a follow up PR.

Should we make that change in the ruby auto-inst prior to merging this?

I am still working with otel ruby maintainer to push the script as a new ruby gem.

Did you land the changes @xuan-cao-swi ? That'd help with the injector project.

We are currently working on the PR to have the autoinstrumentation gem out to replace the autoinstrumention.rb file in this pr
