Doradus LogHA Dockerfile

This is a highly configurable Doradus LogHA image running two instances of logstash and a custom Doradus GEM published to the public Docker Hub Registry. The docker container logs are read by mounting the directory containing your Docker data (/var/log/ in the below example) into the containers /host/var/log. The Doradus LogHA container monitors the mounted directory, tailing the log files and buffers the log events to Redis. The image also monitors the linked Redis container, tailing the log files, queueing up batches of records and when it either reaches the maximum batch size or when the maximum idle time has elapsed then docker-redis-logstash would then write the log events to Doradus for enhanced performance reasons. The image employs the Doradus-logstash GEM to interact with Doradus which is characterized by batch_size, batch_wait and can be viewed at https://git.labs.dell.com/projects/BD/repos/logstash-output-batched_http/browse
