There is something strange, when i launch docker with docker-compose up -d, i see spawn message about debug but nothing about Rails server, later i connect VSCode and rails server starts working.

But nothing is shown inside VSCode, no breakpoints is working... what i'm missing?

Ok now seems working.

What i changed:

• Installed specific version of solargraph
• Installed this fork: https://github.com/wenlock/ruby-debug-ide
• Changed launch.json with

  {
  "version": "0.2.0",
  "configurations": [
  {
    "name": "Rails",
    "type": "Ruby",
    "request": "attach",
    "remoteHost": "0.0.0.0",
    "remotePort": "1234",
    "remoteWorkspaceRoot": "/app",
    "cwd": "${workspaceRoot}",
    "showDebuggerOutput": true
  } ,
  {
    "name": "Sidekiq",
    "type": "Ruby",
    "request": "attach",
    "remoteHost": "0.0.0.0",
    "remotePort": "1235",
    "remoteWorkspaceRoot": "/app",
    "cwd": "${workspaceRoot}",
    "showDebuggerOutput": true
  }
  ]
  }

• Change command in my docker entrypoint with: bundle exec rdebug-ide --host 0.0.0.0 --port 1234 --dispatcher-port 26162 -- bin/rails s -p 3000 -b 0.0.0.0
