Hello,
We are using Elasticsearch, Logstash and Kibana stack with Docker on production to monitor several application servers. They are not badass at all, but we have ~ 2Gb logs data + ~ 1Gb topbeat and packetbeat statistics per day.
Everything working good so far. We had no docker-specific problems except initial configuration, which wasn't too painfull i should say.
You can check out my simple ready-to-go Docker configuration for ELK stack:
