Introduction

This repo exists to fill my own need of running Interactive Brokers Client Portal API.

There are some key modifications made to the init script and related config file, namely:

  • Allow access from all RFC1918 subnets
  • Fix config file logic as it seems broken out-of-the-box
  • Add Jolokia jar to enable exposing metrics
  • Introduce $JAVA_OPTS to allow for easy customization
  • It is possible to see which gateway version is part of the image by running: docker run --rm -ti --entrypoint /bin/ash <image> -c 'unzip dist/ibgroup.web.core.iblink.router.clientportal.gw.jar META-INF/MANIFEST.MF ; cat META-INF/MANIFEST.MF'

Customization

  • One might want to change the default GC to improve latency to reduce the chance of missed executions due to unexpected delays in order execution.
  • It is generally a good idea to set an explicit limit to Java memory usage using the -Xmx option.
  • To provide some insight into the performance of the Client Portal it is possible to hook up Jolokia. To make the metrics exposed by Jolokia available in a more easily digestible format one can use the included jolokia-exporter.yaml together with jolokia_exporter for Prometheus consumption.

Example: JAVA_OPTS="-javaagent:/jolokia-jvm.jar=host=0.0.0.0 -XX:+UseZGC -Xmx128m"
