[SOLVED] How can i debug the the docker container(storm crawler) which is written in java in vs code?

How can i debug the the docker container(storm crawler) which is written in java in vs code?

I am unable to get how can i debug the docker container(which is running storm crawler) in the vs code? I tried looking for https://code.visualstudio.com/docs/containers/debug-common and other https://github.com/DigitalPebble/storm-crawler/wiki/Debug-with-Eclipse. But I did not anything, like how can i configure launch.json file for the same.

Can anyone guide me how can i do this?

Solution

This solves problem for me: Writing launch.json file as :

{
    "version": "0.2.0",
    "configurations": [
       {
           "type": "java",
           "name": "Debug (Attach) - Remote",
           "request": "attach",
           "hostName": "localhost",
           "port": 8000,
       }
    ]
}

and connecting it to docker container of storm crawler as:

version: "3"

services:
  storm-jar:
    command: bash -c "storm kill crawler -w 0 ; storm local target/stormcrawler-1.0.jar org.apache.storm.flux.Flux es-crawler.flux --sleep 86400000" 
    environment:
      - STORM_JAR_JVM_OPTS="-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=8000"
    ports:
      - 8000:8000
