[ https://issues.jboss.org/browse/JBIDE-22225?page=com.atlassian.jira.plugi... ] 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} -- This message was sent by Atlassian JIRA (v6.4.11#64026)
