Hi, I have been experimenting with slider to run docker containers on a yarn cluster (HDP 2.6) by following https://slider.incubator.apache.org/docs/slider_specs/application_pkg_docker.html and was able to launch the redis and nodejs docker containers. However the only thing that I could not get to work is nodejs to connect to redis container. The REDIS_HOST env variable in the appConfig.json shows up as empty. Here is the line that sets this env variable:
"nodejs.options":"-d -e REDIS_HOST=${REDIS_HOST} --net=host" So how do I solve this problem? Specifically, I need is to be able to dynamically discover my peer container address from within one container. Any help is much appreciated. Thanks, Shreyas
