Prove of concept that we can debug node apps through node containers.

Server configurations

The server runs under the following ports:

  • 5000: Server
  • 5001: Debugger


Start server

In the debug pane, you will find a configuration called Start Server which will run the app, and attach the debbuger at the same time

$ docker build --tag poc-hapijs .
$ docker run --rm -p 5000:5000 -d --name poc-hapijs-container poc-hapijs

Attach Debugger (Without Docker)

This configuration will only attach VS code to the debugger so you will need to run in your terminal npm start which is equipped with a node inspector.

Attach Debugger (With Docker)

In order for this configuration to work, you need to make sure that the docker container is running:

$ docker build --tag poc-hapijs .
$ docker run --rm -p 5001:5001 -p 5000:5000 -d --name poc-hapijs-container poc-hapijs

Now simply run the Attach Debugger (With Docker) configuration and create a breakpoint then go to the hapi server
