Debugging Container-Based Designer Modules

Module Development
1

I’m looking for guidance on debugging modules in containers.

I have an 8.3.3 gateway (port 8089) running in a container with modules that I’d like to debug in IntelliJ.
Note that I also have an 8.1 gateway (port 8088) running directly on my computer.

When launching the debugger from IntelliJ, it does start the designer from the correct gateway and allow me to run tests from the script console.

I can set breakpoints in IntelliJ, but it never stops at them, not even in the DesignerHook’s startup(…).

Here’s the services section from the .yml file:

services:
  gateway:
    <<: *ignition-opts
    hostname: gateway
    ports:
      - 8089:8088
      - 8001:8000
    command: >
      -n Ignition-standard
      -m ${GATEWAY_MAX_MEMORY:-4096}
      -r /restore.gwbk
      -a gateway.localtest.me
      -h 8088
      -s 8043
      --

      wrapper.java.additional.12=-Dia.developer.moduleupload=true
    environment:
      GATEWAY_NETWORK_REQUIRESSL: false
      GATEWAY_NETWORK_SECURITYPOLICY: SpecifiedList
      GATEWAY_NETWORK_WHITELIST: Ignition-gatewayr-backup,Ignition-standard-backup
    volumes:
      - gateway-data:/usr/local/bin/ignition/data
      - ./gw-backup:/backup
      - ./gw-init/base.gwbk:/restore.gwbk

Are you trying to debug in the Designer scope or the Gateway scope? What does your IntelliJ launch config look like?

Designer scope.

IntelliJ debugger config:

JDK:
java temurin-17

module/classpath:
-cp designer-launcher

vm/cli options:
-Dignition.gateway.addr.0=localhost:8089 -Dignition.main=com.inductiveautomation.ignition.designer.DesignerStartupHook -Dignition.client.debug=true -Dautologin.username=admin -Dautologin.password=password -Dproject.name=dummy -Dignition.runtimeOverride=true -Dignition.version=dev -Dignition.client.logLevel=INFO @client-designer-args.txt

main method classpath:
com.inductiveautomation.ignition.client.launch.BootstrapSwing

What's this? Is the module you want to breakpoint in also on this classpath? A dependency of this project?
