Rails Byebug Did Not Stop Application

Question

I want to use byebug to debug my application but the app is never stop although I already put byebug inside my code. Here is my Gemfile.

group :deve         


        

Answer 1

To enable debugger mode:

docker-compose run --service-ports web

See this blog post

Answer 2

I was having issues with changes to files (like adding byebug) being synced and found adding consistent to the volume definition helped:

  volumes:
    - .:/usr/src/app:consistent

Answer 3

When using docker-compose in combination with byebug this needs to be added to make it work properly. Found in this blog post

Add this to docker-compose.yml

web:
  ...
  stdin_open: true
  tty: true

Then run docker-compose in deamonized mode and attach to the web container with docker:

docker-compose up -d
docker attach myappname_web_1
