I am trying to attach a remote debugger to a node.js app running in docker from within WebStorm but am unable to do. I can successfully run docker app from IDE but cannot debug it.

I am following this guide to setup remote interpreter : https://www.jetbrains.com/help/webstorm/running-and-debugging-node-js.html#node_debugging_overview

My docker-compose.yaml looks something like this:

ports:
  - 8080:8080
  - 9229:9229

command: [ "npm", "run","debug" ]

package.json has debug script defined like :

"debug":"node --inspect-brk"

If someone has set this up can you please suggest what am I not doing correct ?

Reset to default

You need to bind to all interfaces in container

--inspect=0.0.0.0

or

--inspect-brk=0.0.0.0

Command-line options

However this is dangerous in production environments Exposing the debug port publicly is unsafe

Thank You for all your replies : So this is what my debug script looks like now: "develop": "NODE_ENV=development node -- --inspect=0.0.0.0:8090 ./baseFille.js" Another weird thing is when i send a curl Request to port 8090 (which is suppose to be my debugger port) i don't get any response. Can that be the issue why i cannot debug?

Using Docker Compose as Node.js remote interpreter is not currently supported, see WEB-23404. So you need using Attach to Node.js/Chrome run configuration to attach to your node.js app running in docker:

But, as node binds to localhost by default and thus can't be accessed from outside, you need changing your npm script to "debug":"node --inspect-brk=0.0.0.0:9229", as it's mentioned in @ponury-kostek answer

So i tried using this but for some reason it breaks up abruptly and comes out. Gives a error message with 'driver failed programming external connectivity on endpoint'.
doesn't look related to debugging. see github.com/docker/compose/issues/3277 for some hints
