Ilya Buziuk commented on JBIDE-22225:
-------------------------------------

This issue is trickier than I expected, due to the fact that the app is running inside the docker container. What I tried so far:
- created a docker image with simple node.js app via s2i - https://github.com/sclorg/s2i-nodejs-container
- run the image in a DEV_MODE for debugging

{code}
docker run -p 5858:5858 -p 8080:8080 --env DEV_MODE=true ibuziuk/my-node-app
{code}
- When I now try to debug the app I'm getting null message on handshake (I guess this is because of bridging network adapter)
- The only solution I have found so far for debugging node.js inside docker is to run it with *--net="host"* parameter. 
{code}
docker run --net="host" --env DEV_MODE=true ibuziuk/my-node-app
{code}


Running docker this way allows to perform handshake and makes debugger work.
*--net="host"* gives the container full access to local system services + container will share the host’s network stack and all interfaces from the host will be available to the container.

[~adietish], [~fbricon] Do you happen to know if it is possible / allowed to run image with this option ? According to the documentation:
{code}
Note: --net="host" gives the container full access to local system services such as D-bus and is therefore considered insecure.
{code}
