Remote debug ec2 java instance

Question

My application is running in EC2 as a docker with java application. I'm exposing 5005 port for debug, and locally it works perfectly. However on EC2 environment I get java.net.ConnectException "Connection refused (Connection refused)" when trying to connect using Intelij.

• Security group is set to open ports 80, 5005, 22
• Docker is exposing port 80 and 5005
• Application is running with java args -Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=5005,suspend=n

Am I missing something ?

Answer 1

For those who are still interested, here is a way how to create a Remote JVM Debug on EC2 with docker

1. On the yaml file add the 'port' attribute.

 ports:
     - "5005:5005"

2. To the dockerfile run the Jar with the following command

-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005

3. On the inbound role on the EC2:

Cutsom TCP => 5005 => Your IP

4. In the Intellij create Remote JVM debug
   • In the host enter the host ip
   • Port: 5005
   • Choose JDK 9 or later as the address should be with *:5005
5. Click the Debug Button and it should work
