Steps to run

  1. Install dependencies

    npm install

  2. Build the docker image.

    docker build --pull --rm -f "Dockerfile" -t rheasample:latest "."

  3. Run docker in privileged mode so that you can run iptables commands.

    docker run --privileged --rm -it rheasample:latest

  4. In docker container, run

DEBUG=* \
AMQP_HOST="HOST" \
AMQP_USERNAME="USERNAME" \
AMQP_PASSWORD="PASSWORD" \
RECEIVER_ADDRESS="ADDRESS" \
node index.js

Findings

One of two things should happen after the iptables INPUT rule is removed.

  1. After some time, an error (e.g. ECONNRESET) crashes the process.
  2. Nothing happens, but the process doesn't exit even though all connections should be closed. (It's possible that waiting a long enough time might cause something to happen).

If you're not seeing an error, you can play with the DURATION environment variable to change how long the network is in a bad state. Currently defaulted to 120000 ms (2 minutes).
