My setup is the following one :
- a django server running in a docker with port mapping: 8090:8090
- Eclipse with PyDev

I want to be able to put breakpoint on Pydev (click on a line, step by step)

I found several articles like;
<http://www.pydev.org/manual_adv_remote_debugger.html>

but it's still not working.

1) Should I update the manage.py to "import pydev" ? which lines to add and do I have to copy inside the docker container the pysrc of pydev plugin in order to be able to do the module import ? 

2) Is there a port forwarding needed ? python instance running into docker should have access to remote debug server on host machine ?

3) I found article about pycharm and remote debug using ssh ? not possible to do similar with pydev ?

4) How to "link" my local directory and docker "directory" ?

**[EDIT] I found the solution**

* Copy the eclipse/path\_to\pydev\plugins\org.python.pydev\pysrc directory into a place where your docker container can access it.
* Edit pysrc/pydevd\_file\_utils.py, and add directory mapping between your host and docker container like:
PATHS\_FROM\_ECLIPSE\_TO\_PYTHON = [(r'C:/django',r'/.../lib/django'),
(r'C:/workspace/myapp',r'/var/www/myapp')]
you can set several tuples if you have several paths containing python code
* edit manage.py and add the following 

sys.path.append('/my\_path/to\_pysrc\_/under\_docker/pysrc')
import pydevd
pydevd.settrace(host='172.17.42.1') #IP of your host
* In Pydev, in preferences > Pydev > Run/Debug > Port for remote debugger: 5678
* In Debug Perspective, click on "Start the Pydev server"
* in your docker, run: python manage.py runserver 0.0.0.0:8090 --noreload

(replace 8090 by your http port) 

	+ In Pydev: you will see that the code just break after settrace !
	+ Now You can add some breakpoint and use the debug CLI of Pydev:) Enjoy !
