Nginx reverse proxy set up behind a elastic load balancer and in front of a Play web app. Redirects http to https.
# This sets up a nginx reverse proxy behind a load balancer and in front of
# the Play web app. The setup is illustrated as the following:
#
# LB:80 ==> RP:80 ==> (Redirect to https)
# LB:443 ==> RP:8080 ==> Backend:9001
#
# LB -- Load Balancer
# RP -- Reverse Proxy
#
# IMPORTANT: Remove the line `include /etc/nginx/sites-enabled/*` from this config

Example of how to use curator and elasticsearch python api to update index settings
import elasticsearch
import curator
import json
client = elasticsearch.Elasticsearch()
indices = curator.get_indices(client)
# Filter anything older than or equal to 3 days
_filter = curator.build_filter(kindOf='newer_than', value=3, time_unit='days', timestring='%Y.%m.%d')
indices = curator.apply_filter(indices, **_filter)
