Docker debugging and sub-debugger with random port #107
Description
Hi,
I'm trying to debug rails on a docker container using RubyMine. For lack of a better term, I do have an initial successful hand shake. However, the debugger then creates a "sub-debugger" on a different port. This port seems to be random, therefore, I can't pre-configure to have that port shared. Since the IDE doesn't respond to the sub-debugger port being open, then my rails site doesn't start.
root@f79144807c32:/myapp# rdebug-ide -d --host 0.0.0.0 --port 1234 --dispatcher-port 26162 -- /usr/local/bundle/bin/rails s -b 0.0.0.0 -p 3000 -e development
Fast Debugger (ruby-debug-ide 0.6.1.beta4, debase 0.2.2.beta9, file filtering is supported) listens on 0.0.0.0:1234
Connected from 10.211.55.2
5: Starting control thread
5: Processing in control: b /myapp/app/api/v1/users.rb:6
5: <breakpointAdded no="1" location="/myapp/app/api/v1/users.rb:6"/>
5: Processing in control: start
5: Starting: running program script
Fast Debugger (ruby-debug-ide 0.6.1.beta4, debase 0.2.2.beta9, file filtering is supported) listens on 0.0.0.0:37922
5: Ide process dispatcher notified about sub-debugger which listens on 37922
Note the port 37922. I'm having trouble finding documentation on the sub-debugger. Do you have any suggestions on how to get around this?
Other info, I'm not using "Docker for Mac" I installed docker tools via brew and and my default docker machine is using the parallels driver.
