The Dockerfile on this folder creates an image to create and automate Logstash tasks to run PostgreSQL indexing into
any standard ElasticSearch. Intended to be ran as a command and scheduled by used by some sort of cron, it will naturally die
after completion. Don't expect the container to stay up and running.
It basically runs a task/pod against the ES host.
Be sure to have network access to the ES cluster from wherever you are running the image, otherwise it will fail.
You need to feed the environment variables specified in the conf/opt/es.conf file to make it work.
