Cannot attach docker container with `debugger` while `pry.binding` can about debug

[ko1]

Let me clear the repro process.

• 1. (D(ocker)) docker run with detached mode
• 2. (D) Rails server starts
• 3. (C(lient)) curl
• 4. (D) debugger method is invoked
• 5. (C) docker attach

Questions:

• please correct me if the process is wrong.
• and what happens after (5)?
• How to invoke rails server in docker container?
• Could you repro with simple ruby program instead of Rails program?

Thanks,
Koichi

I have no idea about it.
Have you verified that debugger method is invoked?

Yes. The debug gem's debugger has shown in docker console when runtime ruby has reached the debugger line.

Thank you. I'll create MRE code soon.
