In my lab environment using the docker image https://github.com/jarischaefer/docker-librenms, rrdcached is enabled on one docker container as dedicated rrdcached server and is disabled on poller container and web UI container.
How to configure poller container and web ui container to consume the rrdcached service? Does the docker image have the environment variables like
RRDCACHED_HOST, RRDCACHED_PORT?
Thank you.
